S3

Client

class S3.Client

A low-level client representing Amazon Simple Storage Service (S3)

import boto3

client = boto3.client('s3')

These are the available methods:

abort_multipart_upload(**kwargs)

This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.

For information about permissions required to use the multipart upload, see Multipart Upload and Permissions .

Request Syntax

response = client.abort_multipart_upload(
    Bucket='string',
    Key='string',
    UploadId='string',
    RequestPayer='requester',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The bucket name to which the upload was taking place.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • Key (string) --

    [REQUIRED]

    Key of the object for which the multipart upload was initiated.

  • UploadId (string) --

    [REQUIRED]

    Upload ID that identifies the multipart upload.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

    Bucket='examplebucket',
    Key='bigobject',
    UploadId='xadcOB_7YPBOJuoFiQ9cz4P3Pe6FIZwO4f7wN93uHsNBEw97pl5eNwzExg0LAT2dUN91cOmrEQHDsP3WA60CEg--',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
close()

Closes underlying endpoint connections.

complete_multipart_upload(**kwargs)

Completes a multipart upload by assembling previously uploaded parts.

You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded.

Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. Because a request could fail after the initial 200 OK response has been sent, it is important that you check the response body to determine whether the request succeeded.

Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices .

Warning

You cannot use Content-Type: application/x-www-form-urlencoded with Complete Multipart Upload requests. Also, if you do not provide a Content-Type header, CompleteMultipartUpload returns a 200 OK response.

For more information about multipart uploads, see Uploading Objects Using Multipart Upload .

For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions .

CompleteMultipartUpload has the following special errors:
  • Error code: EntityTooSmall
    • Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part.
    • 400 Bad Request
  • Error code: InvalidPart
    • Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified entity tag might not have matched the part's entity tag.
    • 400 Bad Request
  • Error code: InvalidPartOrder
    • Description: The list of parts was not in ascending order. The parts list must be specified in order by part number.
    • 400 Bad Request
  • Error code: NoSuchUpload
    • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.
    • 404 Not Found

copy(CopySource, Bucket, Key, ExtraArgs=None, Callback=None, SourceClient=None, Config=None)

Copy an object from one S3 location to another.

This is a managed transfer which will perform a multipart copy in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'mybucket',
    'Key': 'mykey'
}
s3.meta.client.copy(copy_source, 'otherbucket', 'otherkey')
Parameters
  • CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
  • Bucket (str) -- The name of the bucket to copy to
  • Key (str) -- The name of the key to copy to
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the copy.
  • SourceClient (botocore or boto3 Client) -- The client to be used for operation that may happen at the source object. For example, this client is used for the head_object that determines the size of the copy. If no client is provided, the current client is used as the client for the source object.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the copy.
copy_object(**kwargs)

Creates a copy of an object that is already stored in Amazon S3.

Note

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API .

All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication . Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately.

If the copy is successful, you receive a response with information about the copied object.

Note

If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.

The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing .

Warning

Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration .

Metadata

When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs .

To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide . For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3 .

x-amz-copy-source-if Headers

To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters:

  • x-amz-copy-source-if-match
  • x-amz-copy-source-if-none-match
  • x-amz-copy-source-if-unmodified-since
  • x-amz-copy-source-if-modified-since

If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:

  • x-amz-copy-source-if-match condition evaluates to true
  • x-amz-copy-source-if-unmodified-since condition evaluates to false

If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:

  • x-amz-copy-source-if-none-match condition evaluates to false
  • x-amz-copy-source-if-modified-since condition evaluates to true

Note

All headers with the x-amz- prefix, including x-amz-copy-source , must be signed.

Server-side encryption

When you perform a CopyObject operation, you can optionally use the appropriate encryption-related headers to encrypt the object using server-side encryption with Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS) or a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption .

If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Checksums

When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header.

Storage Class Options

You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource.

If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.

If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.

If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject .

Parameters
  • ACL (string) --

    The canned ACL to apply to the object.

    This action is not supported by Amazon S3 on Outposts.

  • Bucket (string) --

    [REQUIRED]

    The name of the destination bucket.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • CacheControl (string) -- Specifies caching behavior along the request/reply chain.
  • ChecksumAlgorithm (string) -- Indicates the algorithm you want Amazon S3 to use to create the checksum for the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ContentDisposition (string) -- Specifies presentational information for the object.
  • ContentEncoding (string) -- Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
  • ContentLanguage (string) -- The language the content is in.
  • ContentType (string) -- A standard MIME type describing the format of the object data.
  • CopySource (str or dict) -- [REQUIRED] The name of the source bucket, key name of the source object, and optional version ID of the source object. You can either provide this value as a string or a dictionary. The string form is {bucket}/{key} or {bucket}/{key}?versionId={versionId} if you want to copy a specific version. You can also provide this value as a dictionary. The dictionary format is recommended over the string format because it is more explicit. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted. To specify an S3 access point, provide the access point ARN for the Bucket key in the copy source dictionary. If you want to provide the copy source for an S3 access point as a string instead of a dictionary, the ARN provided must be the full S3 access point object ARN (i.e. {accesspoint_arn}/object/{key})
  • CopySourceIfMatch (string) -- Copies the object if its entity tag (ETag) matches the specified tag.
  • CopySourceIfModifiedSince (datetime) -- Copies the object if it has been modified since the specified time.

  • Key (string) --

    [REQUIRED]

    The key of the destination object.

  • Metadata (dict) --

    A map of metadata to store with the object in S3.

    • (string) --
      • (string) --
  • MetadataDirective (string) -- Specifies whether the metadata is copied from the source object or replaced with metadata provided in the request.
  • TaggingDirective (string) -- Specifies whether the object tag-set are copied from the source object or replaced with tag-set provided in the request.
  • ServerSideEncryption (string) -- The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
  • StorageClass (string) -- By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability.

  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • SSEKMSKeyId (string) -- Specifies the Amazon Web Services KMS key ID to use for object encryption. All GET and PUT requests for an object protected by Amazon Web Services KMS will fail if not made via SSL or using SigV4. For information about configuring using any of the officially supported Amazon Web Services SDKs and Amazon Web Services CLI, see Specifying the Signature Version in Request Authentication in the Amazon S3 User Guide .

  • BucketKeyEnabled (boolean) --

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a COPY action doesn’t affect bucket-level settings for S3 Bucket Key.

  • CopySourceSSECustomerAlgorithm (string) -- Specifies the algorithm to use when decrypting the source object (for example, AES256).
  • CopySourceSSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.
  • CopySourceSSECustomerKeyMD5 (string) --

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • Tagging (string) -- The tag-set for the object destination object this value must be used in conjunction with the TaggingDirective . The tag-set must be encoded as URL Query parameters.
  • ObjectLockMode (string) -- The Object Lock mode that you want to apply to the copied object.
  • ObjectLockRetainUntilDate (datetime) -- The date and time when you want the copied object's Object Lock to expire.
  • ObjectLockLegalHoldStatus (string) -- Specifies whether you want to apply a legal hold to the copied object.
  • ExpectedBucketOwner (string) -- The account ID of the expected destination bucket owner. If the destination bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ExpectedSourceBucketOwner (string) -- The account ID of the expected source bucket owner. If the source bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

    Bucket='destinationbucket',
    CopySource='/sourcebucket/HappyFacejpg',
    Key='HappyFaceCopyjpg',
)

print(response)

Expected Output:

create_bucket(**kwargs)

Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules .

If you want to create an Amazon S3 on Outposts bucket, see Create Bucket .

By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket .

Note

If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets .

Access control lists (ACLs)

When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.

Warning

If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide .

There are two ways to grant the appropriate permissions using the request headers.

  • Specify a canned ACL using the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .

  • Specify access permissions explicitly using the x-amz-grant-read , x-amz-grant-write , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"

Note

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Permissions

In addition to s3:CreateBucket , the following permissions are required when your CreateBucket includes specific headers:

  • ACLs - If your CreateBucket request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both s3:CreateBucket and s3:PutBucketAcl permissions are needed. If the ACL the CreateBucket request is private or doesn't specify any ACLs, only s3:CreateBucket permission is needed.
  • Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request, s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
  • S3 Object Ownership - If your CreateBucket request includes the the x-amz-object-ownership header, s3:PutBucketOwnershipControls permission is required.

The following operations are related to CreateBucket :

    [REQUIRED]

    The name of the bucket to create.

  • CreateBucketConfiguration (dict) --

    The configuration information for the bucket.

    • LocationConstraint (string) --

      Specifies the Region where the bucket will be created. If you don't specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1).

  • GrantFullControl (string) -- Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.
  • GrantRead (string) -- Allows grantee to list the objects in the bucket.
  • GrantReadACP (string) -- Allows grantee to read the bucket ACL.
  • GrantWrite (string) --

    Allows grantee to create new objects in the bucket.

    For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.

  • GrantWriteACP (string) -- Allows grantee to write the ACL for the applicable bucket.
  • ObjectLockEnabledForBucket (boolean) -- Specifies whether you want S3 Object Lock to be enabled for the new bucket.
  • ObjectOwnership (string) --

    The container element for object ownership for a bucket's ownership controls.

    BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

    ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

    BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

response = client.create_bucket(
    Bucket='examplebucket',
    CreateBucketConfiguration={
        'LocationConstraint': 'eu-west-1',
    },
)

print(response)

Expected Output:

    'Location': 'http://examplebucket.s3.amazonaws.com/',
    'ResponseMetadata': {
        '...': '...',
    },
}

The following example creates a bucket.

response = client.create_bucket(
    Bucket='examplebucket',
)

print(response)

Expected Output:

{
    'Location': '/examplebucket',
    'ResponseMetadata': {
        '...': '...',
    },
}
create_multipart_upload(**kwargs)

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart ). You also include this upload ID in the final request to either complete or abort the multipart upload request.

For more information about multipart uploads, see Multipart Upload Overview .

If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy .

For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions .

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4) .

Note

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.

You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use Amazon Web Services KMS keys or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload .

To perform a multipart upload with encryption using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions in the Amazon S3 User Guide .

If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.

For more information, see Protecting Data Using Server-Side Encryption .

Access Permissions

When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

  • Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL .
  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview .

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Server-Side- Encryption-Specific Request Headers

You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use Amazon Web Services managed encryption keys or provide your own encryption key.

  • Use encryption keys managed by Amazon S3 or customer managed key stored in Amazon Web Services Key Management Service (Amazon Web Services KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.
    • x-amz-server-side-encryption
    • x-amz-server-side-encryption-aws-kms-key-id
    • x-amz-server-side-encryption-context

Note

If you specify x-amz-server-side-encryption:aws:kms , but don't provide x-amz-server-side-encryption-aws-kms-key-id , Amazon S3 uses the Amazon Web Services managed key in Amazon Web Services KMS to protect the data.

Warning

All GET and PUT requests for an object protected by Amazon Web Services KMS fail if you don't make them with SSL or by using SigV4.

For more information about server-side encryption with KMS key (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

  • Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.
    • x-amz-server-side-encryption-customer-algorithm
    • x-amz-server-side-encryption-customer-key
    • x-amz-server-side-encryption-customer-key-MD5

For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

Access-Control-List (ACL)-Specific Request Headers

You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs . With this operation, you can grant access permissions using one of the following two methods:

  • Specify a canned ACL (x-amz-acl ) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .
  • Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:
    • x-amz-grant-read
    • x-amz-grant-write
    • x-amz-grant-read-acp
    • x-amz-grant-write-acp
    • x-amz-grant-full-control

You specify each grantee as a type=value pair, where the type is one of the following:

  • id – if the value specified is the canonical user ID of an Amazon Web Services account
  • uri – if you are granting permissions to a predefined group
  • emailAddress – if the value specified is the email address of an Amazon Web Services account

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)

delete_bucket_intelligent_tiering_configuration(**kwargs)

Deletes the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects .

    Bucket='examplebucket',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
delete_object(**kwargs)

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker , to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.

For more information about MFA Delete, see Using MFA Delete . To see sample requests that use versioning, see Sample Request .

You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle ) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject , s3:DeleteObjectVersion , and s3:PutLifeCycleConfiguration actions.

The following action is related to DeleteObject :

    Bucket='examplebucket',
    Key='HappyFace.jpg',
)

print(response)

Expected Output:

{
    'VersionId': 'null',
    'ResponseMetadata': {
        '...': '...',
    },
}
delete_objects(**kwargs)

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete .

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

The following operations are related to DeleteObjects :

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.

Examples

The following example deletes objects from a bucket. The request specifies object versions. S3 deletes specific object versions and returns the key and versions of deleted objects in the response.

response = client.delete_objects(
    Bucket='examplebucket',
    Delete={
        'Objects': [
            {
                'Key': 'HappyFace.jpg',
                'VersionId': '2LWg7lQLnY41.maGB5Z6SWW.dcq0vx7b',
            },
            {
                'Key': 'HappyFace.jpg',
                'VersionId': 'yoz3HB.ZhCS_tKVEmIOr7qYyyAaZSKVd',
            },
        ],
        'Quiet': False,
    },
)

print(response)

Expected Output:

{
    'Deleted': [
        {
            'Key': 'HappyFace.jpg',
            'VersionId': 'yoz3HB.ZhCS_tKVEmIOr7qYyyAaZSKVd',
        },
        {
            'Key': 'HappyFace.jpg',

        '...': '...',
    },
}

The following example deletes objects from a bucket. The bucket is versioned, and the request does not specify the object version to delete. In this case, all versions remain in the bucket and S3 adds a delete marker.

response = client.delete_objects(
    Bucket='examplebucket',
    Delete={
        'Objects': [
            {
                'Key': 'objectkey1',
            },
            {
                'Key': 'objectkey2',
            },
        ],
        'Quiet': False,
    },
)

print(response)

Expected Output:

{
    'Deleted': [
        {
            'DeleteMarker': 'true',

download_fileobj(Bucket, Key, Fileobj, ExtraArgs=None, Callback=None, Config=None)

Download an object from S3 to a file-like object.

The file-like object must be in binary mode.

This is a managed transfer which will perform a multipart download in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.client('s3')

with open('filename', 'wb') as data:
    s3.download_fileobj('mybucket', 'mykey', data)
Parameters
  • Bucket (str) -- The name of the bucket to download from.
  • Key (str) -- The name of the key to download from.
  • Fileobj (a file-like object) -- A file-like object to download into. At a minimum, it must implement the write method and must accept bytes.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the download.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the download.
generate_presigned_post(Bucket, Key, Fields=None, Conditions=None, ExpiresIn=3600)

Builds the url and the form fields used for a presigned s3 post

Parameters
  • Bucket (string) -- The name of the bucket to presign the post to. Note that bucket related conditions should not be included in the conditions parameter.
  • Key (string) -- Key name, optionally add ${filename} to the end to attach the submitted filename. Note that key related conditions and fields are filled out for you and should not be included in the Fields or Conditions parameter.
  • Fields (dict) --

    A dictionary of prefilled form fields to build on top of. Elements that may be included are acl, Cache-Control, Content-Type, Content-Disposition, Content-Encoding, Expires, success_action_redirect, redirect, success_action_status, and x-amz-meta-.

    Note that if a particular element is included in the fields dictionary it will not be automatically added to the conditions list. You must specify a condition for the element as well.

  • Conditions (list) --

    A list of conditions to include in the policy. Each element can be either a list or a structure. For example:

    [
    {"acl": "public-read"}, ["content-length-range", 2, 5], ["starts-with", "$success_action_redirect", ""]

    ]

    Conditions that are included may pertain to acl, content-length-range, Cache-Control, Content-Type, Content-Disposition, Content-Encoding, Expires, success_action_redirect, redirect, success_action_status, and/or x-amz-meta-.

    Note that if you include a condition, you must specify the a valid value in the fields dictionary as well. A value will not be added automatically to the fields dictionary based on the conditions.

  • ExpiresIn (int) -- The number of seconds the presigned post is valid for.
Return type

dict

Returns

A dictionary with two elements: url and fields. Url is the url to post to. Fields is a dictionary filled with the form fields and respective values to use when submitting the post. For example:

{'url': 'https://mybucket.s3.amazonaws.com
'fields': {'acl': 'public-read',

'key': 'mykey', 'signature': 'mysignature', 'policy': 'mybase64 encoded policy'}

}

generate_presigned_url(ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None)

Generate a presigned url given a client, its method, and arguments

Parameters
  • ClientMethod (string) -- The client method to presign for
  • Params (dict) -- The parameters normally passed to ClientMethod.
  • ExpiresIn (int) -- The number of seconds the presigned url is valid for. By default it expires in an hour (3600 seconds)
  • HttpMethod (string) -- The http method to use on the generated url. By default, the http method is whatever is used in the method's model.
Returns

The presigned url

get_bucket_accelerate_configuration(**kwargs)

This implementation of the GET action uses the accelerate subresource to return the Transfer Acceleration state of a bucket, which is either Enabled or Suspended . Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to and from Amazon S3.

To use this operation, you must have permission to perform the s3:GetAccelerateConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide .

You set the Transfer Acceleration state of an existing bucket to Enabled or Suspended by using the PutBucketAccelerateConfiguration operation.

A GET accelerate request does not return a state value for a bucket that has no transfer acceleration state. A bucket has no Transfer Acceleration state if a state has never been set on the bucket.

For more information about transfer acceleration, see Transfer Acceleration in the Amazon S3 User Guide.

Request Syntax

response = client.get_bucket_accelerate_configuration(
    Bucket='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket for which the accelerate configuration is retrieved.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Return type

dict

Returns

Response Syntax

{
    'Status': 'Enabled'|'Suspended'
}

Response Structure

  • (dict) --

    • Status (string) --

      The accelerate configuration of the bucket.

get_bucket_acl(**kwargs)

This implementation of the GET action uses the acl subresource to return the access control list (ACL) of a bucket. To use GET to return the ACL of the bucket, you must have READ_ACP access to the bucket. If READ_ACP permission is granted to the anonymous user, you can return the ACL of the bucket without using an authorization header.

Note

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide .

Setting the BucketKeyEnabled element to true causes Amazon S3 to use an S3 Bucket Key. By default, S3 Bucket Key is not enabled.

            For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

get_bucket_intelligent_tiering_configuration(**kwargs)

Gets the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects .

get_bucket_ownership_controls(**kwargs)

Retrieves OwnershipControls for an Amazon S3 bucket. To use this operation, you must have the s3:GetBucketOwnershipControls permission. For more information about Amazon S3 permissions, see Specifying permissions in a policy .

For information about Amazon S3 Object Ownership, see Using Object Ownership .

The following operations are related to GetBucketOwnershipControls :

  • PutBucketOwnershipControls
  • DeleteBucketOwnershipControls

See also: AWS API Documentation

Request Syntax

response = client.get_bucket_ownership_controls(
    Bucket='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the Amazon S3 bucket whose OwnershipControls you want to retrieve.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Return type

dict

Returns

Response Syntax

{
    'OwnershipControls': {
        'Rules': [
            {
                'ObjectOwnership': 'BucketOwnerPreferred'|'ObjectWriter'|'BucketOwnerEnforced'
            },
        ]
    }
}

Response Structure

  • (dict) --

    • OwnershipControls (dict) --

      The OwnershipControls (BucketOwnerEnforced, BucketOwnerPreferred, or ObjectWriter) currently in effect for this Amazon S3 bucket.

      • Rules (list) --

        The container element for an ownership control rule.

        • (dict) --

          The container element for an ownership control rule.

          • ObjectOwnership (string) --

            The container element for object ownership for a bucket's ownership controls.

            BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

            ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

            BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

get_bucket_policy(**kwargs)

Returns the policy of a specified bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

Warning

As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

For more information about bucket policies, see Using Bucket Policies and User Policies .

            • Account (string) --

              Destination bucket owner account ID. In a cross-account scenario, if you direct Amazon S3 to change replica ownership to the Amazon Web Services account that owns the destination bucket by specifying the AccessControlTranslation property, this is the account ID of the destination bucket owner. For more information, see Replication Additional Configuration: Changing the Replica Owner in the Amazon S3 User Guide .

            • StorageClass (string) --

              The storage class to use when replicating objects, such as S3 Standard or reduced redundancy. By default, Amazon S3 uses the storage class of the source object to create the object replica.

              For valid values, see the StorageClass element of the PUT Bucket replication action in the Amazon S3 API Reference .

            • AccessControlTranslation (dict) --

              Specify this only in a cross-account scenario (where source and destination bucket owners are not the same), and you want to change replica ownership to the Amazon Web Services account that owns the destination bucket. If this is not specified in the replication configuration, the replicas are owned by same Amazon Web Services account that owns the source object.

              • Owner (string) --

                Specifies the replica ownership. For default and valid values, see PUT bucket replication in the Amazon S3 API Reference .

            • EncryptionConfiguration (dict) --

              A container that provides information about encryption. If SourceSelectionCriteria is specified, you must specify this element.

              • ReplicaKmsKeyID (string) --

                Specifies the ID (Key ARN or Alias ARN) of the customer managed Amazon Web Services KMS key stored in Amazon Web Services Key Management Service (KMS) for the destination bucket. Amazon S3 uses this key to encrypt replica objects. Amazon S3 only supports symmetric, customer managed KMS keys. For more information, see Using symmetric and asymmetric keys in the Amazon Web Services Key Management Service Developer Guide .

            • ReplicationTime (dict) --

              A container specifying S3 Replication Time Control (S3 RTC), including whether S3 RTC is enabled and the time when all objects and operations on objects must be replicated. Must be specified together with a Metrics block.

              • Status (string) --

                Specifies whether the replication time is enabled.

              • Time (dict) --

                A container specifying the time by which replication should be complete for all objects and operations on objects.

                  Contains an integer specifying time in minutes.

                  Valid value: 15

            • Metrics (dict) --

              A container specifying replication metrics-related settings enabling replication metrics and events.

              • Status (string) --

                Specifies whether the replication metrics are enabled.

                A container specifying the time threshold for emitting the s3:Replication:OperationMissedThreshold event.

                • Minutes (integer) --

                  Contains an integer specifying time in minutes.

                  Valid value: 15

          • DeleteMarkerReplication (dict) --

            Specifies whether Amazon S3 replicates delete markers. If you specify a Filter in your replication configuration, you must also include a DeleteMarkerReplication element. If your Filter includes a Tag element, the DeleteMarkerReplication Status must be set to Disabled, because Amazon S3 does not support replicating delete markers for tag-based rules. For an example configuration, see Basic Rule Configuration .

            For more information about delete marker replication, see Basic Rule Configuration .

            Note

            If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility .

            • Status (string) --

              Indicates whether to replicate delete markers.

              Note

              Indicates whether to replicate delete markers.

Examples

The following example retrieves website configuration of a bucket.

response = client.get_bucket_website(
    Bucket='examplebucket',
)

print(response)

Expected Output:

{
    'ErrorDocument': {
        'Key': 'error.html',
    },
    'IndexDocument': {
        'Suffix': 'index.html',
    },
    'ResponseMetadata': {
        '...': '...',
    },
}
get_object(**kwargs)

Retrieves objects from Amazon S3. To use GET , you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg , you can name it photos/2006/February/sample.jpg .

To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg , specify the resource as /photos/2006/February/sample.jpg . For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket , specify the resource as /examplebucket/photos/2006/February/sample.jpg . For more information about request types, see HTTP Host Header Bucket Specification .

For more information about returning the ACL of an object, see GetObjectAcl .

If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject . Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects .

Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning

By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.

Note

  • If you supply a versionId , you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission.
  • If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

For more information about versioning, see PutBucketVersioning .

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type , Content-Language , Expires , Cache-Control , Content-Disposition , and Content-Encoding . To override these header values in the GET response, you use the following request parameters.

Note

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

  • response-content-type
  • response-content-language
  • response-expires
  • response-cache-control
  • response-content-disposition
  • response-content-encoding
Additional Considerations about Request Headers

If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true , and; If-Unmodified-Since condition evaluates to false ; then, S3 returns 200 OK and the data requested.

If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:If-None-Match condition evaluates to false , and; If-Modified-Since condition evaluates to true ; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232 .

get_object_acl(**kwargs)

Returns the access control list (ACL) of an object. To use this operation, you must have s3:GetObjectAcl permissions or READ_ACP access to the object. For more information, see Mapping of ACL permissions and access policy permissions in the Amazon S3 User Guide

This action is not supported by Amazon S3 on Outposts.

Versioning

By default, GET returns ACL information about the current version of an object. To return ACL information about a different version, use the versionId subresource.

Note

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, requests to read ACLs are still supported and return the bucket-owner-full-control ACL with the owner being the account that created the bucket. For more information, see Controlling object ownership and disabling ACLs in the Amazon S3 User Guide .

The following operations are related to GetObjectAcl :

get_object_attributes(**kwargs)

Retrieves all the metadata from an object without returning the object itself. This action is useful if you're interested only in an object's metadata. To use GetObjectAttributes , you must have READ access to the object.

GetObjectAttributes combines the functionality of GetObjectAcl , GetObjectLegalHold , GetObjectLockConfiguration , GetObjectRetention , GetObjectTagging , HeadObject , and ListParts . All of the data returned with each of those individual calls can be returned with a single call to GetObjectAttributes .

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide .

Note

  • Encryption request headers, such as x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with Amazon Web Services KMS keys stored in Amazon Web Services Key Management Service (SSE-KMS) or server-side encryption with Amazon S3 managed encryption keys (SSE-S3). If your object does use these types of keys, you'll get an HTTP 400 Bad Request error.
  • The last modified property in this case is the creation date of the object.

Consider the following when using request headers:

  • If both of the If-Match and If-Unmodified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 200 OK and the data requested:
    • If-Match condition evaluates to true .
    • If-Unmodified-Since condition evaluates to false .
  • If both of the If-None-Match and If-Modified-Since headers are present in the request as follows, then Amazon S3 returns the HTTP status code 304 Not Modified :
    • If-None-Match condition evaluates to false .
    • If-Modified-Since condition evaluates to true .

For more information about conditional requests, see RFC 7232 .

Permissions

The permissions that you need to use this operation depend on whether the bucket is versioned. If the bucket is versioned, you need both the s3:GetObjectVersion and s3:GetObjectVersionAttributes permissions for this operation. If the bucket is not versioned, you need the s3:GetObject and s3:GetObjectAttributes permissions. For more information, see Specifying Permissions in a Policy in the Amazon S3 User Guide . If the object that you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 Not Found ("no such key") error.
  • If you don't have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 Forbidden ("access denied") error.

When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • Key (string) --

    [REQUIRED]

    The object key.

  • VersionId (string) -- The version ID used to reference a specific version of the object.
  • MaxParts (integer) -- Sets the maximum number of parts to return.
  • PartNumberMarker (integer) -- Specifies the part after which listing should begin. Only parts with higher part numbers will be listed.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ObjectAttributes (list) --

    [REQUIRED]

    An XML header that specifies the fields at the root level that you want returned in the response. Fields that you do not specify are not returned.

Retrieves the PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation, you must have the s3:GetBucketPublicAccessBlock permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy .

Warning

When Amazon S3 evaluates the PublicAccessBlock configuration for a bucket or an object, it checks the PublicAccessBlock configuration for both the bucket (or the bucket that contains the object) and the bucket owner's account. If the PublicAccessBlock settings are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public" .

        'BlockPublicAcls': True|False,
        'IgnorePublicAcls': True|False,
        'BlockPublicPolicy': True|False,
        'RestrictPublicBuckets': True|False
    }
}

Response Structure

  • (dict) --

    • PublicAccessBlockConfiguration (dict) --

      The PublicAccessBlock configuration currently in effect for this Amazon S3 bucket.

      • BlockPublicAcls (boolean) --

        Specifies whether Amazon S3 should block public access control lists (ACLs) for this bucket and objects in this bucket. Setting this element to TRUE causes the following behavior:

        • PUT Bucket ACL and PUT Object ACL calls fail if the specified ACL is public.
        • PUT Object calls fail if the request includes a public ACL.
        • PUT Bucket calls fail if the request includes a public ACL.

        Enabling this setting doesn't affect existing policies or ACLs.

      • IgnorePublicAcls (boolean) --

        Specifies whether Amazon S3 should ignore public ACLs for this bucket and objects in this bucket. Setting this element to TRUE causes Amazon S3 to ignore all public ACLs on this bucket and objects in this bucket.

        Enabling this setting doesn't affect the persistence of any existing ACLs and doesn't prevent new public ACLs from being set.

      • BlockPublicPolicy (boolean) --

        Specifies whether Amazon S3 should block public bucket policies for this bucket. Setting this element to TRUE causes Amazon S3 to reject calls to PUT Bucket policy if the specified bucket policy allows public access.

        Enabling this setting doesn't affect existing bucket policies.

      • RestrictPublicBuckets (boolean) --

        Specifies whether Amazon S3 should restrict public bucket policies for this bucket. Setting this element to TRUE restricts access to this bucket to only Amazon Web Service principals and authorized users within this account if the bucket has a public policy.

        Enabling this setting doesn't affect previously stored bucket policies, except that public and cross-account access within any public bucket policy, including non-public delegation to specific accounts, is blocked.

get_waiter(waiter_name)

Returns an object that can wait for some condition.

Parameters
waiter_name (str) -- The name of the waiter to get. See the waiters section of the service docs for a list of available waiters.
Returns
The specified waiter object.
Return type
botocore.waiter.Waiter
head_bucket(**kwargs)

This action is useful to determine if a bucket exists and you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.

If the bucket does not exist or you do not have permission to access it, the HEAD request returns a generic 404 Not Found or 403 Forbidden code. A message body is not included, so you cannot determine the exception beyond these error codes.

To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

To use this API against an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using the Amazon Web Services SDKs, you provide the ARN in place of the bucket name. For more information see, Using access points .

See also: AWS API Documentation

Request Syntax

response = client.head_bucket(
    Bucket='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The bucket name.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns

None

Exceptions

  • S3.Client.exceptions.NoSuchBucket

Examples

This operation checks to see if a bucket exists.

response = client.head_bucket(
    Bucket='acl1',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
head_object(**kwargs)

The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.

A HEAD request has the same options as a GET action on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic 404 Not Found or 403 Forbidden code. It is not possible to retrieve the exact exception beyond these error codes.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Note

  • Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
  • The last modified property in this case is the creation date of the object.

Request headers are limited to 8 KB in size. For more information, see Common Request Headers .

Consider the following when using request headers:

  • Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:
    • If-Match condition evaluates to true , and;
    • If-Unmodified-Since condition evaluates to false ;

Then Amazon S3 returns 200 OK and the data requested.

  • Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:
    • If-None-Match condition evaluates to false , and;
    • If-Modified-Since condition evaluates to true ;

Then Amazon S3 returns the 304 Not Modified response code.

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 ("access denied") error.

Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket containing the object.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • IfMatch (string) -- Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.
  • IfModifiedSince (datetime) -- Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.
  • IfNoneMatch (string) -- Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.
  • IfUnmodifiedSince (datetime) -- Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.
  • Key (string) --

    [REQUIRED]

    The object key.

  • Range (string) -- Because HeadObject returns only the metadata for an object, this parameter has no effect.
  • VersionId (string) -- VersionId used to reference a specific version of the object.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • PartNumber (integer) -- Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumMode (string) --

    To retrieve the checksum, this parameter must be enabled.

    In addition, if you enable ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

    • ChecksumSHA256 (string) --

      The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide .

    • ETag (string) --

      An entity tag (ETag) is an opaque identifier assigned by a web server to a specific version of a resource found at a URL.

    • MissingMeta (integer) --

      This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.

    • VersionId (string) --

      Version of the object.

    • CacheControl (string) --

      Specifies caching behavior along the request/reply chain.

    • ContentDisposition (string) --

      Indicates whether the object uses an S3 Bucket Key for server-side encryption with Amazon Web Services KMS (SSE-KMS).

    • StorageClass (string) --

      Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.

      For more information, see Storage Classes .

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

    • ReplicationStatus (string) --

      Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

      In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (GetObject ) or object metadata (HeadObject ) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:

      • If requesting an object from the source bucket , Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs . Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf , are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
      • If requesting an object from a destination bucket , Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.
      • When replicating objects to multiple destination buckets , the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

      For more information, see Replication .

    • PartsCount (integer) --

      The count of parts this object has. This value is only returned if you specify partNumber in your request and the object was uploaded as a multipart upload.

    • ObjectLockMode (string) --

      The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock .

    • ObjectLockRetainUntilDate (datetime) --

      The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.

    • ObjectLockLegalHoldStatus (string) --

      Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock .

Exceptions

  • S3.Client.exceptions.NoSuchKey

list_bucket_analytics_configurations(**kwargs)

Lists the analytics configurations for the bucket. You can have up to 1,000 analytics configurations per bucket.

This action supports list pagination and does not return more than 100 configurations at a time. You should always check the IsTruncated element in the response. If there are no more configurations to list, IsTruncated is set to false. If there are more configurations to list, IsTruncated is set to true, and there will be a value in NextContinuationToken . You use the NextContinuationToken value to continue the pagination of the list by passing the value in continuation-token in the request to GET the next page.

To use this operation, you must have permissions to perform the s3:GetAnalyticsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

list_bucket_intelligent_tiering_configurations(**kwargs)

Lists the S3 Intelligent-Tiering configuration from the specified bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects .

list_bucket_inventory_configurations(**kwargs)

Returns a list of inventory configurations for the bucket. You can have up to 1,000 analytics configurations per bucket.

This action supports list pagination and does not return more than 100 configurations at a time. Always check the IsTruncated element in the response. If there are no more configurations to list, IsTruncated is set to false. If there are more configurations to list, IsTruncated is set to true, and there is a value in NextContinuationToken . You use the NextContinuationToken value to continue the pagination of the list by passing the value in continuation-token in the request to GET the next page.

To use this operation, you must have permissions to perform the s3:GetInventoryConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

list_multipart_uploads(**kwargs)

This action lists in-progress multipart uploads. An in-progress multipart upload is a multipart upload that has been initiated using the Initiate Multipart Upload request, but has not yet been completed or aborted.

This action returns at most 1,000 multipart uploads in the response. 1,000 multipart uploads is the maximum number of uploads a response can include, which is also the default value. You can further limit the number of uploads in a response by specifying the max-uploads parameter in the response. If additional multipart uploads satisfy the list criteria, the response will contain an IsTruncated element with the value true. To list the additional multipart uploads, use the key-marker and upload-id-marker request parameters.

In the response, the uploads are sorted by key. If your application has initiated more than one multipart upload using the same object key, then uploads in the response are first sorted by key. Additionally, uploads are sorted in ascending order within each key by the upload initiation time.

For more information on multipart uploads, see Uploading Objects Using Multipart Upload .

For information on permissions required to use the multipart upload API, see Multipart Upload and Permissions .

    MaxUploads=123,
    Prefix='string',
    UploadIdMarker='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket to which the multipart upload was initiated.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • Delimiter (string) --

    Character you use to group keys.

    All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes . If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.

  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • KeyMarker (string) --

    Together with upload-id-marker, this parameter specifies the multipart upload after which listing should begin.

    If upload-id-marker is not specified, only the keys lexicographically greater than the specified key-marker will be included in the list.

    If upload-id-marker is specified, any multipart uploads for a key equal to the key-marker might also be included, provided those multipart uploads have upload IDs lexicographically greater than the specified upload-id-marker .

  • MaxUploads (integer) -- Sets the maximum number of multipart uploads, from 1 to 1,000, to return in the response body. 1,000 is the maximum number of uploads that can be returned in a response.
  • Prefix (string) -- Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.)
  • UploadIdMarker (string) -- Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored. Otherwise, any multipart uploads for a key equal to the key-marker might be included in the list only if they have an upload ID lexicographically greater than the specified upload-id-marker .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

list_object_versions(**kwargs)

Returns metadata about all versions of the objects in a bucket. You can also use request parameters as selection criteria to return metadata about a subset of all the object versions.

Warning

To use this operation, you must have permissions to perform the s3:ListBucketVersions action. Be aware of the name difference.

Note

A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately.

To use this operation, you must have READ access to the bucket.

This action is not supported by Amazon S3 on Outposts.

Request Syntax

response = client.list_object_versions(
    Bucket='string',
    Delimiter='string',
    EncodingType='url',
    KeyMarker='string',
    MaxKeys=123,
    Prefix='string',
    VersionIdMarker='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The bucket name that contains the objects.

  • Delimiter (string) -- A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.
  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • KeyMarker (string) -- Specifies the key to start with when listing objects in a bucket.
  • MaxKeys (integer) -- Sets the maximum number of keys returned in the response. By default the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more. If additional keys satisfy the search criteria, but were not returned because max-keys was exceeded, the response contains <isTruncated>true</isTruncated>. To return the additional keys, see key-marker and version-id-marker.
  • Prefix (string) -- Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.) You can use prefix with delimiter to roll up numerous objects into a single result under CommonPrefixes.
  • VersionIdMarker (string) -- Specifies the object version you want to start listing from.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Response Structure

  • (dict) --

    • IsTruncated (boolean) --

      A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria.

    • Marker (string) --

      Indicates where in the bucket listing begins. Marker is included in the response if it was sent with the request.

    • NextMarker (string) --

      When response is truncated (the IsTruncated element value in the response is true), you can use the key name in this field as marker in the subsequent request to get next set of objects. Amazon S3 lists objects in alphabetical order Note: This element is returned only if you have delimiter request parameter specified. If response does not include the NextMarker and it is truncated, you can use the value of the last Key in the response as the marker in the subsequent request to get the next set of object keys.

    • Contents (list) --

      Metadata about each object returned.

      • (dict) --

        An object consists of data and its descriptive metadata.

        • Key (string) --

          The name that you assign to an object. You use the object key to retrieve the object.

        • LastModified (datetime) --

          Creation date of the object.

        • ETag (string) --

          The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

          • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.
          • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.
          • If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.
        • ChecksumAlgorithm (list) --

          The algorithm that was used to create a checksum of the object.

          • (string) --
        • Size (integer) --

          Size in bytes of the object

        • StorageClass (string) --

          The class of storage used to store the object.

        • Owner (dict) --

          The owner of the object

          • DisplayName (string) --

            Container for the display name of the owner.

          • ID (string) --

            Container for the ID of the owner.

    • Name (string) --

      The bucket name.

    • Prefix (string) --

      Keys that begin with the indicated prefix.

    • Delimiter (string) --

      Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.

    • MaxKeys (integer) --

      The maximum number of keys returned in the response body.

    • CommonPrefixes (list) --

      All of the keys (up to 1,000) rolled up in a common prefix count as a single return when calculating the number of returns.

      A response can contain CommonPrefixes only if you specify a delimiter.

      CommonPrefixes contains all (if there are any) keys between Prefix and the next occurrence of the string specified by the delimiter.

      CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix.

      For example, if the prefix is notes/ and the delimiter is a slash (/) as in notes/summer/july, the common prefix is notes/summer/. All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.

      • (dict) --

        Container for all (if there are any) keys between Prefix and the next occurrence of the string specified by a delimiter. CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix. For example, if the prefix is notes/ and the delimiter is a slash (/) as in notes/summer/july, the common prefix is notes/summer/.

        • Prefix (string) --

          Container for the specified common prefix.

    • EncodingType (string) --

      Encoding type used by Amazon S3 to encode object keys in the response.

Exceptions

  • S3.Client.exceptions.NoSuchBucket

list_objects_v2(**kwargs)

Returns some or all (up to 1,000) of the objects in a bucket with each request. You can use the request parameters as selection criteria to return a subset of the objects in a bucket. A 200 OK response can contain valid or invalid XML. Make sure to design your application to parse the contents of the response and handle it appropriately. Objects are returned sorted in an ascending order of the respective key names in the list. For more information about listing objects, see Listing object keys programmatically

To use this operation, you must have READ access to the bucket.

To use this action in an Identity and Access Management (IAM) policy, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

    • StartAfter (string) --

      If StartAfter was sent with the request, it is included in the response.

Exceptions

  • S3.Client.exceptions.NoSuchBucket

Examples

The following example retrieves object list. The request specifies max keys to limit response to include only 2 object keys.

response = client.list_objects_v2(
    Bucket='examplebucket',

list_parts(**kwargs)

Lists the parts that have been uploaded for a specific multipart upload. This operation must include the upload ID, which you obtain by sending the initiate multipart upload request (see CreateMultipartUpload ). This request returns a maximum of 1,000 uploaded parts. The default number of parts returned is 1,000 parts. You can restrict the number of parts returned by specifying the max-parts request parameter. If your multipart upload consists of more than 1,000 parts, the response returns an IsTruncated field with the value of true, and a NextPartNumberMarker element. In subsequent ListParts requests you can include the part-number-marker query string parameter and set its value to the NextPartNumberMarker field value from the previous response.

If the upload was created using a checksum algorithm, you will need to have permission to the kms:Decrypt action for the request to succeed.

For more information on multipart uploads, see Uploading Objects Using Multipart Upload .

For information on permissions required to use the multipart upload API, see Multipart Upload and Permissions .

    • AbortDate (datetime) --

      If the bucket has a lifecycle rule configured with an action to abort incomplete multipart uploads and the prefix in the lifecycle rule matches the object name in the request, then the response includes this header indicating when the initiated multipart upload will become eligible for abort operation. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy .

      The response will also include the x-amz-abort-rule-id header that will provide the ID of the lifecycle configuration rule that defines this action.

    • AbortRuleId (string) --

      This header is returned along with the x-amz-abort-date header. It identifies applicable lifecycle configuration rule that defines the action to abort incomplete multipart uploads.

    • Bucket (string) --

      The name of the bucket to which the multipart upload was initiated. Does not return the access point ARN or access point alias if used.

    • Key (string) --

      Object key for which the multipart upload was initiated.

    • UploadId (string) --

      Upload ID identifying the multipart upload whose parts are being listed.

    • PartNumberMarker (integer) --

      When a list is truncated, this element specifies the last part in the list, as well as the value to use for the part-number-marker request parameter in a subsequent request.

    • NextPartNumberMarker (integer) --

      When a list is truncated, this element specifies the last part in the list, as well as the value to use for the part-number-marker request parameter in a subsequent request.

    • MaxParts (integer) --

      Maximum number of parts that were allowed in the response.

    • IsTruncated (boolean) --

      Indicates whether the returned list of parts is truncated. A true value indicates that the list was truncated. A list can be truncated if the number of parts exceeds the limit returned in the MaxParts element.

    • Parts (list) --

      Container for elements related to a particular part. A response can contain zero or more Part elements.

      • (dict) --

        Container for elements related to a part.

put_bucket_accelerate_configuration(**kwargs)

Sets the accelerate configuration of an existing bucket. Amazon S3 Transfer Acceleration is a bucket-level feature that enables you to perform faster data transfers to Amazon S3.

To use this operation, you must have permission to perform the s3:PutAccelerateConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

The Transfer Acceleration state of a bucket can be set to one of the following two values:

  • Enabled – Enables accelerated data transfers to the bucket.
  • Suspended – Disables accelerated data transfers to the bucket.

The GetBucketAccelerateConfiguration action returns the transfer acceleration state of a bucket.

After setting the Transfer Acceleration state of a bucket to Enabled, it might take up to thirty minutes before the data transfer rates to the bucket increase.

The name of the bucket used for Transfer Acceleration must be DNS-compliant and must not contain periods (".").

For more information about transfer acceleration, see Transfer Acceleration .

The following operations are related to PutBucketAccelerateConfiguration :

Request Syntax

response = client.put_bucket_accelerate_configuration(
    Bucket='string',
    AccelerateConfiguration={
        'Status': 'Enabled'|'Suspended'
    },
    ExpectedBucketOwner='string',
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket for which the accelerate configuration is set.

  • AccelerateConfiguration (dict) --

    [REQUIRED]

    Container for setting the transfer acceleration state.

    • Status (string) --

      Specifies the transfer acceleration status of the bucket.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

Returns

None

put_bucket_acl(**kwargs)

Sets the permissions on an existing bucket using access control lists (ACL). For more information, see Using ACLs . To set the ACL of a bucket, you must have WRITE_ACP permission.

You can use one of the following two ways to set a bucket's permissions:

  • Specify the ACL in the request body
  • Specify permissions using request headers

Note

You cannot specify access permission using both the body and the request headers.

Depending on your application needs, you may choose to set the ACL on a bucket using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, then you can continue to use that approach.

Warning

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide .

Access Permissions

You can set access permissions using one of the following methods:

  • Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-acl . If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL .

  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use the x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-write header grants create, overwrite, and delete objects permission to LogDelivery group predefined by Amazon S3 and two Amazon Web Services accounts identified by their email addresses.

x-amz-grant-write: uri="http://acs.amazonaws.com/groups/s3/LogDelivery", id="111122223333", id="555566667777"

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>lt;/Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

response = client.put_bucket_acl(
    Bucket='examplebucket',
    GrantFullControl='id=examplee7a2f25102679df27bb0ae12b3f85be6f290b936c4393484',
    GrantWrite='uri=http://acs.amazonaws.com/groups/s3/LogDelivery',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_analytics_configuration(**kwargs)

Sets an analytics configuration for the bucket (specified by the analytics configuration ID). You can have up to 1,000 analytics configurations per bucket.

You can choose to have storage class analysis export analysis reports sent to a comma-separated values (CSV) flat file. See the DataExport request element. Reports are updated daily and are based on the object filters that you configure. When selecting data export, you specify a destination bucket and an optional destination prefix where the file is written. You can export the data to a destination bucket in a different account. However, the destination bucket must be in the same Region as the bucket that you are making the PUT analytics configuration to. For more information, see Amazon S3 Analytics – Storage Class Analysis .

Warning

You must create a bucket policy on the destination bucket where the exported file is written to grant permissions to Amazon S3 to write objects to the bucket. For an example policy, see Granting Permissions for Amazon S3 Inventory and Storage Class Analysis .

To use this operation, you must have permissions to perform the s3:PutAnalyticsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

Special Errors
    • HTTP Error: HTTP 400 Bad Request
    • Code: InvalidArgument
    • Cause: Invalid argument.
    • HTTP Error: HTTP 400 Bad Request
    • Code: TooManyConfigurations
    • Cause: You are attempting to create a new configuration but have already reached the 1,000-configuration limit.
    • HTTP Error: HTTP 403 Forbidden
    • Code: AccessDenied
    • Cause: You are not the owner of the specified bucket, or you do not have the s3:PutAnalyticsConfiguration bucket permission to set the configuration on the bucket.

put_bucket_cors(**kwargs)

Sets the cors configuration for your bucket. If the configuration exists, Amazon S3 replaces it.

To use this operation, you must be allowed to perform the s3:PutBucketCORS action. By default, the bucket owner has this permission and can grant it to others.

You set this configuration on a bucket so that the bucket can service cross-origin requests. For example, you might want to enable a request whose origin is http://www.example.com to access your Amazon S3 bucket at my.example.bucket.com by using the browser's XMLHttpRequest capability.

To enable cross-origin resource sharing (CORS) on a bucket, you add the cors subresource to the bucket. The cors subresource is an XML document in which you configure rules that identify origins and the HTTP methods that can be executed on your bucket. The document is limited to 64 KB in size.

When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a bucket, it evaluates the cors configuration on the bucket and uses the first CORSRule rule that matches the incoming browser request to enable a cross-origin request. For a rule to match, the following conditions must be met:

  • The request's Origin header must match AllowedOrigin elements.
  • The request method (for example, GET, PUT, HEAD, and so on) or the Access-Control-Request-Method header in case of a pre-flight OPTIONS request must be one of the AllowedMethod elements.
  • Every header specified in the Access-Control-Request-Headers request header of a pre-flight request must match an AllowedHeader element.

For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide .

put_bucket_encryption(**kwargs)

This action uses the encryption subresource to configure default encryption and Amazon S3 Bucket Key for an existing bucket.

Default encryption for a bucket can use server-side encryption with Amazon S3-managed keys (SSE-S3) or customer managed keys (SSE-KMS). If you specify default encryption using SSE-KMS, you can also configure Amazon S3 Bucket Key. When the default encryption is SSE-KMS, if you upload an object to the bucket and do not specify the KMS key to use for encryption, Amazon S3 uses the default Amazon Web Services managed KMS key for your account. For information about default encryption, see Amazon S3 default bucket encryption in the Amazon S3 User Guide . For more information about S3 Bucket Keys, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Warning

This action requires Amazon Web Services Signature Version 4. For more information, see Authenticating Requests (Amazon Web Services Signature Version 4) .

To use this operation, you must have permissions to perform the s3:PutEncryptionConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • ServerSideEncryptionConfiguration (dict) --

    [REQUIRED]

    Specifies the default server-side-encryption configuration.

    • Rules (list) -- [REQUIRED]

      Container for information about a particular server-side encryption configuration rule.

      • (dict) --

        Specifies the default server-side encryption configuration.

        • ApplyServerSideEncryptionByDefault (dict) --

          Specifies the default server-side encryption to apply to new objects in the bucket. If a PUT Object request doesn't specify any server-side encryption, this default encryption will be applied.

          • SSEAlgorithm (string) -- [REQUIRED]

            Server-side encryption algorithm to use for the default encryption.

          • KMSMasterKeyID (string) --

            Amazon Web Services Key Management Service (KMS) customer Amazon Web Services KMS key ID to use for the default encryption. This parameter is allowed if and only if SSEAlgorithm is set to aws:kms .

            You can specify the key ID or the Amazon Resource Name (ARN) of the KMS key. However, if you are using encryption with cross-account or Amazon Web Services service operations you must use a fully qualified KMS key ARN. For more information, see Using encryption for cross-account operations .

            For example:
            • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab
            • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

            Warning

            Amazon S3 only supports symmetric KMS keys and not asymmetric KMS keys. For more information, see Using symmetric and asymmetric keys in the Amazon Web Services Key Management Service Developer Guide .

        • BucketKeyEnabled (boolean) --

          Specifies whether Amazon S3 should use an S3 Bucket Key with server-side encryption using KMS (SSE-KMS) for new objects in the bucket. Existing objects are not affected. Setting the BucketKeyEnabled element to true causes Amazon S3 to use an S3 Bucket Key. By default, S3 Bucket Key is not enabled.

          For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns

None

put_bucket_intelligent_tiering_configuration(**kwargs)

Puts a S3 Intelligent-Tiering configuration to the specified bucket. You can have up to 1,000 S3 Intelligent-Tiering configurations per bucket.

The S3 Intelligent-Tiering storage class is designed to optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead. S3 Intelligent-Tiering delivers automatic cost savings in three low latency and high throughput access tiers. To get the lowest storage cost on data that can be accessed in minutes to hours, you can choose to activate additional archiving capabilities.

The S3 Intelligent-Tiering storage class is the ideal storage class for data with unknown, changing, or unpredictable access patterns, independent of object size or retention period. If the size of an object is less than 128 KB, it is not monitored and not eligible for auto-tiering. Smaller objects can be stored, but they are always charged at the Frequent Access tier rates in the S3 Intelligent-Tiering storage class.

For more information, see Storage class for automatically optimizing frequently and infrequently accessed objects .

Operations related to PutBucketIntelligentTieringConfiguration include:

Note

You only need S3 Intelligent-Tiering enabled on a bucket if you want to automatically move objects stored in the S3 Intelligent-Tiering storage class to the Archive Access or Deep Archive Access tier.

put_bucket_inventory_configuration(**kwargs)

This implementation of the PUT action adds an inventory configuration (identified by the inventory ID) to the bucket. You can have up to 1,000 inventory configurations per bucket.

Amazon S3 inventory generates inventories of the objects in the bucket on a daily or weekly basis, and the results are published to a flat file. The bucket that is inventoried is called the source bucket, and the bucket where the inventory flat file is stored is called the destination bucket. The destination bucket must be in the same Amazon Web Services Region as the source bucket.

When you configure an inventory for a source bucket, you specify the destination bucket where you want the inventory to be stored, and whether to generate the inventory daily or weekly. You can also configure what object metadata to include and whether to inventory all object versions or only current versions. For more information, see Amazon S3 Inventory in the Amazon S3 User Guide.

Warning

You must create a bucket policy on the destination bucket to grant permissions to Amazon S3 to write objects to the bucket in the defined location. For an example policy, see Granting Permissions for Amazon S3 Inventory and Storage Class Analysis .

To use this operation, you must have permissions to perform the s3:PutInventoryConfiguration action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide.

put_bucket_lifecycle(**kwargs)

Warning

For an updated version of this API, see PutBucketLifecycleConfiguration . This version has been deprecated. Existing lifecycle configurations will work. For new lifecycle configurations, use the updated API.

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. For information about lifecycle configuration, see Object Lifecycle Management in the Amazon S3 User Guide .

By default, all Amazon S3 resources, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration) are private. Only the resource owner, the Amazon Web Services account that created the resource, can access it. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, users must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. Explicit denial also supersedes any other permissions. If you want to prevent users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

  • s3:DeleteObject
  • s3:DeleteObjectVersion
  • s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide .

For more examples of transitioning objects to storage classes such as STANDARD_IA or ONEZONE_IA, see Examples of Lifecycle Configuration .

Danger

This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.

put_bucket_lifecycle_configuration(**kwargs)

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle .

Note

Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, or a combination of both. Accordingly, this section describes the latest API. The previous version of the API supported filtering based only on an object key name prefix, which is supported for backward compatibility. For the related API description, see PutBucketLifecycle .

Rules

You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:

  • Filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, or a combination of both.
  • Status whether the rule is in effect.
  • One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements .

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. Explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

  • s3:DeleteObject
  • s3:DeleteObjectVersion
  • s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources .

put_bucket_logging(**kwargs)

Set the logging parameters for a bucket and to specify permissions for who can view and modify the logging parameters. All logs are saved to buckets in the same Amazon Web Services Region as the source bucket. To set the logging status of a bucket, you must be the bucket owner.

The bucket owner is automatically granted FULL_CONTROL to all logs. You use the Grantee request element to grant access to other people. The Permissions request element specifies the kind of access the grantee has to the logs.

Warning

If the target bucket for log delivery uses the bucket owner enforced setting for S3 Object Ownership, you can't use the Grantee request element to grant access to others. Permissions can only be granted using policies. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide .

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request.
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress></Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>

To enable logging, you use LoggingEnabled and its children request elements. To disable logging, you use an empty BucketLoggingStatus request element:

<BucketLoggingStatus xmlns="http://doc.s3.amazonaws.com/2006-03-01" />

Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket for which to set the logging parameters.

  • BucketLoggingStatus (dict) --

    [REQUIRED]

    Container for logging status information.

    • LoggingEnabled (dict) --

      Describes where logs are stored and the prefix that Amazon S3 assigns to all log object keys for a bucket. For more information, see PUT Bucket logging in the Amazon S3 API Reference .

      • TargetBucket (string) -- [REQUIRED]

        Specifies the bucket where you want Amazon S3 to store server access logs. You can have your logs delivered to any bucket that you own, including the same bucket that is being logged. You can also configure multiple buckets to deliver their logs to the same target bucket. In this case, you should choose a different TargetPrefix for each source bucket so that the delivered log files can be distinguished by key.

      • TargetGrants (list) --

        Container for granting information.

        Buckets that use the bucket owner enforced setting for Object Ownership don't support target grants. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide .

        • (dict) --

          Container for granting information.

          Buckets that use the bucket owner enforced setting for Object Ownership don't support target grants. For more information, see Permissions server access log delivery in the Amazon S3 User Guide .

          • Grantee (dict) --

            Container for the person being granted permissions.

            • DisplayName (string) --

              Screen name of the grantee.

            • EmailAddress (string) --

              Email address of the grantee.

              Note

              Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

              • US East (N. Virginia)
              • US West (N. California)
              • US West (Oregon)

              • Asia Pacific (Sydney)
              • Asia Pacific (Tokyo)
              • Europe (Ireland)
              • South America (São Paulo)

              For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

            • ID (string) --

              The canonical user ID of the grantee.

            • Type (string) -- [REQUIRED]

              Type of grantee

            • URI (string) --

              URI of the grantee group.

  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns

None

Examples

The following example sets logging policy on a bucket. For the Log Delivery group to deliver logs to the destination bucket, it needs permission for the READ_ACP action which the policy grants.

response = client.put_bucket_logging(
    Bucket='sourcebucket',
    BucketLoggingStatus={
        'LoggingEnabled': {
            'TargetBucket': 'targetbucket',
            'TargetGrants': [
                {
                    'Grantee': {
                        'Type': 'Group',
                        'URI': 'http://acs.amazonaws.com/groups/global/AllUsers',

                },
            ],
            'TargetPrefix': 'MyBucketLogs/',
        },
    },
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_metrics_configuration(**kwargs)

Sets a metrics configuration (specified by the metrics configuration ID) for the bucket. You can have up to 1,000 metrics configurations per bucket. If you're updating an existing metrics configuration, note that this is a full replacement of the existing metrics configuration. If you don't include the elements you want to keep, they are erased.

To use this operation, you must have permissions to perform the s3:PutMetricsConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

For information about CloudWatch request metrics for Amazon S3, see Monitoring Metrics with Amazon CloudWatch .

Returns

None

put_bucket_notification_configuration(**kwargs)

Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications .

Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.

By default, your bucket has no event notifications configured. That is, the notification configuration will be an empty NotificationConfiguration .

<NotificationConfiguration>

</NotificationConfiguration>

This action replaces the existing notification configuration with the configuration you include in the request body.

After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events .

You can disable notifications by adding the empty NotificationConfiguration element.

For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in Amazon Web Services General Reference .

By default, only the bucket owner can configure notifications on a bucket. However, bucket owners can use a bucket policy to grant permission to other users to set this configuration with s3:PutBucketNotification permission.

Note

The PUT notification is an atomic operation. For example, suppose your notification configuration includes SNS topic, SQS queue, and Lambda function configurations. When you send a PUT request with this configuration, Amazon S3 sends test messages to your SNS topic. If the message fails, the entire PUT action will fail, and Amazon S3 will not add the configuration to your bucket.

Responses

If the configuration in the request body includes only one TopicConfiguration specifying only the s3:ReducedRedundancyLostObject event type, the response will also include the x-amz-sns-test-message-id header containing the message ID of the test notification sent to the topic.

    Bucket='examplebucket',
    NotificationConfiguration={
        'TopicConfigurations': [
            {
                'Events': [
                    's3:ObjectCreated:*',
                ],

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_ownership_controls(**kwargs)

Creates or modifies OwnershipControls for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketOwnershipControls permission. For more information about Amazon S3 permissions, see Specifying permissions in a policy .

For information about Amazon S3 Object Ownership, see Using object ownership .

The following operations are related to PutBucketOwnershipControls :

  • GetBucketOwnershipControls
  • DeleteBucketOwnershipControls

See also: AWS API Documentation

Request Syntax

response = client.put_bucket_ownership_controls(
    Bucket='string',
    ContentMD5='string',
    ExpectedBucketOwner='string',
    OwnershipControls={
        'Rules': [
            {
                'ObjectOwnership': 'BucketOwnerPreferred'|'ObjectWriter'|'BucketOwnerEnforced'
            },
        ]
    }
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the Amazon S3 bucket whose OwnershipControls you want to set.

  • ContentMD5 (string) --

    The MD5 hash of the OwnershipControls request body.

    For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • OwnershipControls (dict) --

    [REQUIRED]

    The OwnershipControls (BucketOwnerEnforced, BucketOwnerPreferred, or ObjectWriter) that you want to apply to this Amazon S3 bucket.

    • Rules (list) -- [REQUIRED]

      The container element for an ownership control rule.

      • (dict) --

        The container element for an ownership control rule.

        • ObjectOwnership (string) -- [REQUIRED]

          The container element for object ownership for a bucket's ownership controls.

          BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

          ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

          BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

Returns

None

put_bucket_policy(**kwargs)

Applies an Amazon S3 bucket policy to an Amazon S3 bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the PutBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

Warning

As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

For more information, see Bucket policy examples .

The following operations are related to PutBucketPolicy :

See also: AWS API Documentation

Request Syntax

response = client.put_bucket_policy(
    Bucket='string',
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256',
    ConfirmRemoveSelfBucketAccess=True|False,
    Policy='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket.

  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • ConfirmRemoveSelfBucketAccess (boolean) -- Set this parameter to true to confirm that you want to remove your permissions to change this bucket policy in the future.
  • Policy (string) --

    [REQUIRED]

    The bucket policy as a JSON document.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns

None

Examples

The following example sets a permission policy on a bucket.

response = client.put_bucket_policy(
    Bucket='examplebucket',
    Policy='{"Version": "2012-10-17", "Statement": [{ "Sid": "id-1","Effect": "Allow","Principal": {"AWS": "arn:aws:iam::123456789012:root"}, "Action": [ "s3:PutObject","s3:PutObjectAcl"], "Resource": ["arn:aws:s3:::acl3/*" ] } ]}',
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_replication(**kwargs)

Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 User Guide .

Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket or buckets where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information.

A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset.

To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication , Status , and Priority .

Note

If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility .

For information about enabling versioning on a bucket, see Using Versioning .

Handling Replication of Encrypted Objects

By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with KMS keys. To replicate Amazon Web Services KMS-encrypted objects, add the following: SourceSelectionCriteria , SseKmsEncryptedObjects , Status , EncryptionConfiguration , and ReplicaKmsKeyID . For information about replication configuration, see Replicating Objects Created with SSE Using KMS keys .

For information on PutBucketReplication errors, see List of replication-related error codes

Permissions

To create a PutBucketReplication request, you must have s3:PutReplicationConfiguration permissions for the bucket.

By default, a resource owner, in this case the Amazon Web Services account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources .

Note

To perform this operation, the user or role performing the action must have the iam:PassRole permission.

Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket

  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • ReplicationConfiguration (dict) --

    [REQUIRED]

    A container for replication rules. You can add up to 1,000 rules. The maximum size of a replication configuration is 2 MB.

    • Role (string) -- [REQUIRED]

      The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role that Amazon S3 assumes when replicating objects. For more information, see How to Set Up Replication in the Amazon S3 User Guide .

    • Rules (list) -- [REQUIRED]

      A container for one or more replication rules. A replication configuration must have at least one rule and can contain a maximum of 1,000 rules.

      • (dict) --

        Specifies which Amazon S3 objects to replicate and where to store the replicas.

        • ID (string) --

          A unique identifier for the rule. The maximum value is 255 characters.

        • Priority (integer) --

          The priority indicates which rule has precedence whenever two or more replication rules conflict. Amazon S3 will attempt to replicate objects according to all replication rules. However, if there are two or more rules with the same destination bucket, then objects will be replicated according to the rule with the highest priority. The higher the number, the higher the priority.

          For more information, see Replication in the Amazon S3 User Guide .

        • Prefix (string) --

          An object key name prefix that identifies the object or objects to which the rule applies. The maximum prefix length is 1,024 characters. To include all objects in a bucket, specify an empty string.

          Warning

          Replacement must be made for object keys containing special characters (such as carriage returns) when using XML requests. For more information, see XML related object key constraints .

        • Filter (dict) --

          A filter that identifies the subset of objects to which the replication rule applies. A Filter must specify exactly one Prefix , Tag , or an And child element.

          • Prefix (string) --

            An object key name prefix that identifies the subset of objects to which the rule applies.

            Warning

            Replacement must be made for object keys containing special characters (such as carriage returns) when using XML requests. For more information, see XML related object key constraints .

          • Tag (dict) --

            A container for specifying a tag key and value.

            The rule applies only to objects that have the tag in their tag set.

              Name of the object key.

            • Value (string) -- [REQUIRED]

              Value of the tag.

          • And (dict) --

            A container for specifying rule filters. The filters determine the subset of objects to which the rule applies. This element is required only if you specify more than one filter. For example:

            • If you specify both a Prefix and a Tag filter, wrap these filters in an And tag.
            • If you specify a filter based on multiple tags, wrap the Tag elements in an And tag.
            • Prefix (string) --

              An object key name prefix that identifies the subset of objects to which the rule applies.

        • Status (string) -- [REQUIRED]

          Specifies whether the rule is enabled.

        • SourceSelectionCriteria (dict) --

          A container that describes additional filters for identifying the source objects that you want to replicate. You can choose to enable or disable the replication of these objects. Currently, Amazon S3 supports only the filter that you can specify for objects created with server-side encryption using a customer managed key stored in Amazon Web Services Key Management Service (SSE-KMS).

          • SseKmsEncryptedObjects (dict) --

            A container for filter information for the selection of Amazon S3 objects encrypted with Amazon Web Services KMS. If you include SourceSelectionCriteria in the replication configuration, this element is required.

            • Status (string) -- [REQUIRED]

              Specifies whether Amazon S3 replicates objects created with server-side encryption using an Amazon Web Services KMS key stored in Amazon Web Services Key Management Service.

          • ReplicaModifications (dict) --

            A filter that you can specify for selections for modifications on replicas. Amazon S3 doesn't replicate replica modifications by default. In the latest version of replication configuration (when Filter is specified), you can specify this element and set the status to Enabled to replicate modifications on replicas.

            Note

            If you don't specify the Filter element, Amazon S3 assumes that the replication configuration is the earlier version, V1. In the earlier version, this element is not allowed

          • Account (string) --

            Destination bucket owner account ID. In a cross-account scenario, if you direct Amazon S3 to change replica ownership to the Amazon Web Services account that owns the destination bucket by specifying the AccessControlTranslation property, this is the account ID of the destination bucket owner. For more information, see Replication Additional Configuration: Changing the Replica Owner in the Amazon S3 User Guide .

          • StorageClass (string) --

            The storage class to use when replicating objects, such as S3 Standard or reduced redundancy. By default, Amazon S3 uses the storage class of the source object to create the object replica.

            For valid values, see the StorageClass element of the PUT Bucket replication action in the Amazon S3 API Reference .

          • AccessControlTranslation (dict) --

            Specify this only in a cross-account scenario (where source and destination bucket owners are not the same), and you want to change replica ownership to the Amazon Web Services account that owns the destination bucket. If this is not specified in the replication configuration, the replicas are owned by same Amazon Web Services account that owns the source object.

            • Owner (string) -- [REQUIRED]

              Specifies the replica ownership. For default and valid values, see PUT bucket replication in the Amazon S3 API Reference .

          • EncryptionConfiguration (dict) --

            A container that provides information about encryption. If SourceSelectionCriteria is specified, you must specify this element.

            • ReplicaKmsKeyID (string) --

              Specifies the ID (Key ARN or Alias ARN) of the customer managed Amazon Web Services KMS key stored in Amazon Web Services Key Management Service (KMS) for the destination bucket. Amazon S3 uses this key to encrypt replica objects. Amazon S3 only supports symmetric, customer managed KMS keys. For more information, see Using symmetric and asymmetric keys in the Amazon Web Services Key Management Service Developer Guide .

          • ReplicationTime (dict) --

            A container specifying S3 Replication Time Control (S3 RTC), including whether S3 RTC is enabled and the time when all objects and operations on objects must be replicated. Must be specified together with a Metrics block.

            • Status (string) -- [REQUIRED]

              Specifies whether the replication time is enabled.

            • Time (dict) -- [REQUIRED]

              A container specifying the time by which replication should be complete for all objects and operations on objects.

              • Minutes (integer) --

                Contains an integer specifying time in minutes.

                Valid value: 15

        • DeleteMarkerReplication (dict) --

          Specifies whether Amazon S3 replicates delete markers. If you specify a Filter in your replication configuration, you must also include a DeleteMarkerReplication element. If your Filter includes a Tag element, the DeleteMarkerReplication Status must be set to Disabled, because Amazon S3 does not support replicating delete markers for tag-based rules. For an example configuration, see Basic Rule Configuration .

          For more information about delete marker replication, see Basic Rule Configuration .

          Note

          If you are using an earlier version of the replication configuration, Amazon S3 handles replication of delete markers differently. For more information, see Backward Compatibility .

          • Status (string) --

            Indicates whether to replicate delete markers.

            Note

            Indicates whether to replicate delete markers.

response = client.put_bucket_request_payment(
    Bucket='examplebucket',
    RequestPaymentConfiguration={
        'Payer': 'Requester',
    },
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_tagging(**kwargs)

Sets the tags for a bucket.

Use tags to organize your Amazon Web Services bill to reflect your own cost structure. To do this, sign up to get your Amazon Web Services account bill with tag key values included. Then, to see the cost of combined resources, organize your billing information according to resources with the same tag key values. For example, you can tag several resources with a specific application name, and then organize your billing information to see the total cost of that application across several services. For more information, see Cost Allocation and Tagging and Using Cost Allocation in Amazon S3 Bucket Tags .

Note

When this operation sets the tags for a bucket, it will overwrite any current tags the bucket already has. You cannot use this operation to add tags to an existing list of tags.

To use this operation, you must have permissions to perform the s3:PutBucketTagging action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

PutBucketTagging has the following special errors:
  • Error code: InvalidTagError
  • Error code: MalformedXMLError
    • Description: The XML provided does not match the schema.
  • Error code: OperationAbortedError
    • Description: A conflicting conditional action is currently in progress against this resource. Please try again.
  • Error code: InternalError
    • Description: The service was unable to apply the provided tag to the bucket.

Returns

None

Examples

The following example sets tags on a bucket. Any existing tags are replaced.

response = client.put_bucket_tagging(
    Bucket='examplebucket',
    Tagging={
        'TagSet': [
            {
                'Key': 'Key1',
                'Value': 'Value1',
            },
            {
                'Key': 'Key2',
                'Value': 'Value2',
            },
        ],
    },
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_bucket_versioning(**kwargs)

Sets the versioning state of an existing bucket.

You can set the versioning state with one of the following values:

Enabled —Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID.

Suspended —Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null.

If the versioning state has never been set on a bucket, it has no versioning state; a GetBucketVersioning request does not return a versioning state value.

In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket.

Warning

If you have an object expiration lifecycle policy in your non-versioned bucket and you want to maintain the same permanent delete behavior when you enable versioning, you must add a noncurrent expiration policy. The noncurrent expiration lifecycle policy will manage the deletes of the noncurrent object versions in the version-enabled bucket. (A version-enabled bucket maintains one current and zero or more noncurrent object versions.) For more information, see Lifecycle and Versioning .

Examples

The following example sets versioning configuration on bucket. The configuration enables versioning on the bucket.

response = client.put_bucket_versioning(
    Bucket='examplebucket',
    VersioningConfiguration={
        'MFADelete': 'Disabled',
        'Status': 'Enabled',

}
put_bucket_website(**kwargs)

Sets the configuration of the website that is specified in the website subresource. To configure a bucket as a website, you can add this subresource on the bucket with website configuration information such as the file name of the index document and any redirect rules. For more information, see Hosting Websites on Amazon S3 .

This PUT action requires the S3:PutBucketWebsite permission. By default, only the bucket owner can configure the website attached to a bucket; however, bucket owners can allow other users to set the website configuration by writing a bucket policy that grants them the S3:PutBucketWebsite permission.

To redirect all website requests sent to the bucket's website endpoint, you add a website configuration with the following elements. Because all requests are sent to another website, you don't need to provide index document name for the bucket.

  • WebsiteConfiguration
  • RedirectAllRequestsTo
  • HostName
  • Protocol

If you want granular control over redirects, you can use the following elements to add routing rules that describe conditions for redirecting requests and information about the redirect destination. In this case, the website configuration must provide an index document for the bucket, because some requests might not be redirected.

  • WebsiteConfiguration
  • IndexDocument
  • Suffix
  • ErrorDocument
  • Key
  • RoutingRules
  • RoutingRule
  • Condition
  • HttpErrorCodeReturnedEquals
  • KeyPrefixEquals
  • Redirect
  • Protocol
  • HostName
  • ReplaceKeyPrefixWith
  • ReplaceKeyWith
  • HttpRedirectCode

Amazon S3 has a limitation of 50 routing rules per website configuration. If you require more than 50 routing rules, you can use object redirect. For more information, see Configuring an Object Redirect in the Amazon S3 User Guide .

Examples

The following example adds website configuration to a bucket.

response = client.put_bucket_website(
    Bucket='examplebucket',
    ContentMD5='',
    WebsiteConfiguration={
        'ErrorDocument': {
            'Key': 'error.html',
        },
        'IndexDocument': {
            'Suffix': 'index.html',
        },
    },
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
put_object(**kwargs)

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.

To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

Note

  • To successfully complete the PutObject request, you must have the s3:PutObject in your IAM permissions.
  • To successfully change the objects acl of your PutObject request, you must have the s3:PutObjectAcl in your IAM permissions.
  • The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide .

Server-side Encryption

You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption .

If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported .

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Storage Class Options

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.

For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

For more information, see Storage Classes in the Amazon S3 User Guide .
  • WebsiteRedirectLocation (string) --

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata .

    In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

    x-amz-website-redirect-location: /anotherPage.html

    In the following example, the request header sets the object redirect to another website:

    x-amz-website-redirect-location: http://www.example.com/

  • SSEKMSKeyId (string) -- If x-amz-server-side-encryption is present and has the value of aws:kms , this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetrical customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms , but do not provide``x-amz-server-side-encryption-aws-kms-key-id`` , Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.
  • SSEKMSEncryptionContext (string) -- Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
  • BucketKeyEnabled (boolean) --

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .

put_object_acl(**kwargs)

Uses the acl subresource to set the access control list (ACL) permissions for a new or existing object in an S3 bucket. You must have WRITE_ACP permission to set the ACL of an object. For more information, see What permissions can I grant? in the Amazon S3 User Guide .

This action is not supported by Amazon S3 on Outposts.

Depending on your application needs, you can choose to set the ACL on an object using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, you can continue to use that approach. For more information, see Access Control List (ACL) Overview in the Amazon S3 User Guide .

Warning

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide .

Access Permissions

You can set access permissions using one of the following methods:

  • Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-ac l. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL .

  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants list objects permission to the two Amazon Web Services accounts identified by their email addresses.

x-amz-grant-read: emailAddress="xyz@amazon.com", emailAddress="abc@amazon.com"

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request.
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>lt;/Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

Versioning

The ACL of an object is set at the object version level. By default, PUT sets the ACL of the current version of an object. To set the ACL of a different version, use the versionId subresource.

put_object_tagging(**kwargs)

Sets the supplied tag-set to an object that already exists in a bucket.

A tag is a key-value pair. You can associate tags with an object by sending a PUT request against the tagging subresource that is associated with the object. You can retrieve tags by sending a GET request. For more information, see GetObjectTagging .

For tagging-related restrictions related to characters and encodings, see Tag Restrictions . Note that Amazon S3 limits the maximum number of tags to 10 tags per object.

To use this operation, you must have permission to perform the s3:PutObjectTagging action. By default, the bucket owner has this permission and can grant this permission to others.

To put tags of any other version, use the versionId query parameter. You also need permission for the s3:PutObjectVersionTagging action.

For information about the Amazon S3 object tagging feature, see Object Tagging .

Special Errors
    • Code: InvalidTagError
    • Cause: The tag provided was not a valid tag. This error can occur if the tag did not pass input validation. For more information, see `Object Tagging <https://docs.aws.amazon.com/AmazonS3/latest/dev/object-tagging.html>`__ .
    • Code: MalformedXMLError

put_public_access_block(**kwargs)

Creates or modifies the PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy .

Warning

When Amazon S3 evaluates the PublicAccessBlock configuration for a bucket or an object, it checks the PublicAccessBlock configuration for both the bucket (or the bucket that contains the object) and the bucket owner's account. If the PublicAccessBlock configurations are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.

For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of "Public" .

Request Syntax

response = client.put_public_access_block(
    Bucket='string',
    ContentMD5='string',
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256',
    PublicAccessBlockConfiguration={
        'BlockPublicAcls': True|False,

        'BlockPublicPolicy': True|False,
        'RestrictPublicBuckets': True|False
    },
    ExpectedBucketOwner='string'
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the Amazon S3 bucket whose PublicAccessBlock configuration you want to set.

  • ContentMD5 (string) --

    The MD5 hash of the PutPublicAccessBlock request body.

    For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.

  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • PublicAccessBlockConfiguration (dict) --

    [REQUIRED]

    The PublicAccessBlock configuration that you want to apply to this Amazon S3 bucket. You can enable the configuration options in any combination. For more information about when Amazon S3 considers a bucket or object public, see The Meaning of "Public" in the Amazon S3 User Guide .

    • BlockPublicAcls (boolean) --

      Specifies whether Amazon S3 should block public access control lists (ACLs) for this bucket and objects in this bucket. Setting this element to TRUE causes the following behavior:

      • PUT Bucket ACL and PUT Object ACL calls fail if the specified ACL is public.
      • PUT Object calls fail if the request includes a public ACL.
      • PUT Bucket calls fail if the request includes a public ACL.

      Enabling this setting doesn't affect existing policies or ACLs.

    • IgnorePublicAcls (boolean) --

      Specifies whether Amazon S3 should ignore public ACLs for this bucket and objects in this bucket. Setting this element to TRUE causes Amazon S3 to ignore all public ACLs on this bucket and objects in this bucket.

      Enabling this setting doesn't affect the persistence of any existing ACLs and doesn't prevent new public ACLs from being set.

    • BlockPublicPolicy (boolean) --

      Specifies whether Amazon S3 should block public bucket policies for this bucket. Setting this element to TRUE causes Amazon S3 to reject calls to PUT Bucket policy if the specified bucket policy allows public access.

      Enabling this setting doesn't affect existing bucket policies.

    • RestrictPublicBuckets (boolean) --

      Specifies whether Amazon S3 should restrict public bucket policies for this bucket. Setting this element to TRUE restricts access to this bucket to only Amazon Web Service principals and authorized users within this account if the bucket has a public policy.

      Enabling this setting doesn't affect previously stored bucket policies, except that public and cross-account access within any public bucket policy, including non-public delegation to specific accounts, is blocked.

  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns

None

restore_object(**kwargs)

Restores an archived copy of an object back into Amazon S3

This action is not supported by Amazon S3 on Outposts.

This action performs the following types of requests:

  • select - Perform a select query on an archived object
  • restore an archive - Restore an archived object

To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide .

Querying Archives with Select Requests

You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon S3 User Guide .

When making a select request, do the following:

  • Define an output location for the select query's output. This must be an Amazon S3 bucket in the same Amazon Web Services Region as the bucket that contains the archive object that is being queried. The Amazon Web Services account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon S3 User Guide . For more information about the S3 structure in the request body, see the following:
  • Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.
    • The following expression returns all records from the specified object. SELECT * FROM Object
    • Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers. SELECT s._1, s._2 FROM Object s WHERE s._3 > 100
    • If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE , you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE , the first row is skipped for the query.) You cannot mix ordinal positions with header column names. SELECT s.Id, s.FirstName, s.SSN FROM S3Object s

For more information about using SQL with S3 Glacier Select restore, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide .

When making a select request, you can also do the following:

  • To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.
  • Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.

The following are additional important facts about the select feature:

  • The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.
  • You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.
  • Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409 .
Restoring objects

Objects that you archive to the S3 Glacier or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers are not accessible in real time. For objects in Archive Access or Deep Archive Access tiers you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier. For objects in S3 Glacier or S3 Glacier Deep Archive storage classes you must first initiate a restore request, and then wait until a temporary copy of the object is available. To access an archived object, you must restore the object for the duration (number of days) that you specify.

To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.

When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:

  • Expedited - Expedited retrievals allow you to quickly access your data stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
  • Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
  • Bulk - Bulk retrievals are the lowest-cost retrieval option in S3 Glacier, enabling you to retrieve large amounts, even petabytes, of data inexpensively. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Bulk retrievals are free for objects stored in S3 Intelligent-Tiering.

For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide .

You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide .

To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide .

After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.

If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide .

Responses

A successful action returns either the 200 OK or 202 Accepted status code.

  • If the object is not previously restored, then Amazon S3 returns 202 Accepted in the response.
  • If the object is previously restored, Amazon S3 returns 200 OK in the response.
Special Errors
    • Code: RestoreAlreadyInProgress
    • Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)
    • HTTP Status Code: 409 Conflict
    • SOAP Fault Code Prefix: Client
    • Code: GlacierExpeditedRetrievalNotAvailable
    • Cause: expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)
    • HTTP Status Code: 503
    • SOAP Fault Code Prefix: N/A

    Bucket='examplebucket',
    Key='archivedobjectkey',
    RestoreRequest={
        'Days': 1,
        'GlacierJobParameters': {
            'Tier': 'Expedited',
        },
    },
)

print(response)

Expected Output:

{
    'ResponseMetadata': {
        '...': '...',
    },
}
select_object_content(**kwargs)

This action filters the contents of an Amazon S3 object based on a simple structured query language (SQL) statement. In the request, along with the SQL expression, you must also specify a data serialization format (JSON, CSV, or Apache Parquet) of the object. Amazon S3 uses this format to parse object data into records, and returns only records that match the specified SQL expression. You must also specify the data serialization format for the response.

This action is not supported by Amazon S3 on Outposts.

For more information about Amazon S3 Select, see Selecting Content from Objects and SELECT Command in the Amazon S3 User Guide .

For more information about using SQL with Amazon S3 Select, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide .

Permissions

You must have s3:GetObject permission for this operation. Amazon S3 Select does not support anonymous access. For more information about permissions, see Specifying Permissions in a Policy in the Amazon S3 User Guide .

Object Data Formats

You can use Amazon S3 Select to query objects that have the following format properties:

  • CSV, JSON, and Parquet - Objects must be in CSV, JSON, or Parquet format.
  • UTF-8 - UTF-8 is the only encoding type Amazon S3 Select supports.
  • GZIP or BZIP2 - CSV and JSON files can be compressed using GZIP or BZIP2. GZIP and BZIP2 are the only compression formats that Amazon S3 Select supports for CSV and JSON files. Amazon S3 Select supports columnar compression for Parquet using GZIP or Snappy. Amazon S3 Select does not support whole-object compression for Parquet objects.
  • Server-side encryption - Amazon S3 Select supports querying objects that are protected with server-side encryption. For objects that are encrypted with customer-provided encryption keys (SSE-C), you must use HTTPS, and you must use the headers that are documented in the GetObject . For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) in the Amazon S3 User Guide . For objects that are encrypted with Amazon S3 managed encryption keys (SSE-S3) and Amazon Web Services KMS keys (SSE-KMS), server-side encryption is handled transparently, so you don't need to specify anything. For more information about server-side encryption, including SSE-S3 and SSE-KMS, see Protecting Data Using Server-Side Encryption in the Amazon S3 User Guide .
Working with the Response Body

Given the response size is unknown, Amazon S3 Select streams the response as a series of messages and includes a Transfer-Encoding header with chunked as its value in the response. For more information, see Appendix: SelectObjectContent Response .

GetObject Support

The SelectObjectContent action does not support the following GetObject functionality. For more information, see GetObject .

  • Range : Although you can specify a scan range for an Amazon S3 Select request (see SelectObjectContentRequest - ScanRange in the request parameters), you cannot specify the range of bytes of an object to return.
  • GLACIER, DEEP_ARCHIVE and REDUCED_REDUNDANCY storage classes: You cannot specify the GLACIER, DEEP_ARCHIVE, or REDUCED_REDUNDANCY storage classes. For more information, about storage classes see Storage Classes in the Amazon S3 User Guide .
Special Errors

upload_file(Filename, Bucket, Key, ExtraArgs=None, Callback=None, Config=None)

Upload a file to an S3 object.

Usage:

import boto3
s3 = boto3.resource('s3')
s3.meta.client.upload_file('/tmp/hello.txt', 'mybucket', 'hello.txt')

Similar behavior as S3Transfer's upload_file() method, except that parameters are capitalized. Detailed examples can be found at S3Transfer's Usage.

Parameters
  • Filename (str) -- The path to the file to upload.
  • Bucket (str) -- The name of the bucket to upload to.
  • Key (str) -- The name of the key to upload to.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed upload arguments see boto3.s3.transfer.S3Transfer.ALLOWED_UPLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the upload.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the transfer.
upload_fileobj(Fileobj, Bucket, Key, ExtraArgs=None, Callback=None, Config=None)

Upload a file-like object to S3.

The file-like object must be in binary mode.

This is a managed transfer which will perform a multipart upload in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.client('s3')

with open('filename', 'rb') as data:
    s3.upload_fileobj(data, 'mybucket', 'mykey')
Parameters
  • Fileobj (a file-like object) -- A file-like object to upload. At a minimum, it must implement the read method, and must return bytes.
  • Bucket (str) -- The name of the bucket to upload to.
  • Key (str) -- The name of the key to upload to.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed upload arguments see boto3.s3.transfer.S3Transfer.ALLOWED_UPLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the upload.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the upload.
upload_part(**kwargs)

Uploads a part in a multipart upload.

Note

In this operation, you provide part data in your request. However, you have an option to specify your existing Amazon S3 object as a data source for the part you are uploading. To upload a part from an existing object, you use the UploadPartCopy operation.

You must initiate a multipart upload (see CreateMultipartUpload ) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier, that you must include in your upload part request.

Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide .

To ensure that data is not corrupted when traversing the network, specify the Content-MD5 header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.

If the upload request is signed with Signature Version 4, then Amazon Web Services S3 uses the x-amz-content-sha256 header as a checksum instead of Content-MD5 . For more information see Authenticating Requests: Using the Authorization Header (Amazon Web Services Signature Version 4) .

Note: After you initiate multipart upload and upload one or more parts, you must either complete or abort multipart upload in order to stop getting charged for storage of the uploaded parts. Only after you either complete or abort multipart upload, Amazon S3 frees up the parts storage and stops charging you for the parts storage.

For more information on multipart uploads, go to Multipart Upload Overview in the Amazon S3 User Guide .

For information on the permissions required to use the multipart upload API, go to Multipart Upload and Permissions in the Amazon S3 User Guide .

You can optionally request server-side encryption where Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it for you when you access it. You have the option of providing your own encryption key, or you can use the Amazon Web Services managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in the request must match the headers you used in the request to initiate the upload by using CreateMultipartUpload . For more information, go to Using Server-Side Encryption in the Amazon S3 User Guide .

Server-side encryption is supported by the S3 Multipart Upload actions. Unless you are using a customer-provided encryption key, you don't need to specify the encryption parameters in each UploadPart request. Instead, you only need to specify the server-side encryption parameters in the initial Initiate Multipart request. For more information, see CreateMultipartUpload .

If you requested server-side encryption using a customer-provided encryption key in your initiate multipart upload request, you must provide identical encryption information in each part upload using the following headers.

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

  • ChecksumCRC32 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ChecksumCRC32C (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32C checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ChecksumSHA1 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ChecksumSHA256 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • Key (string) --

    [REQUIRED]

    Object key for which the multipart upload was initiated.

  • PartNumber (integer) --

    [REQUIRED]

    Part number of part being uploaded. This is a positive integer between 1 and 10,000.

  • UploadId (string) --

    [REQUIRED]

    Upload ID identifying the multipart upload whose part is being uploaded.

  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header . This must be the same encryption key specified in the initiate multipart upload request.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

upload_part_copy(**kwargs)

Uploads a part by copying data from an existing object as data source. You specify the data source by adding the request header x-amz-copy-source in your request and a byte range by adding the request header x-amz-copy-source-range in your request.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide .

Note

Instead of using an existing object as part data, you might use the UploadPart action and provide data in your request.

You must initiate a multipart upload before you can upload any part. In response to your initiate request. Amazon S3 returns a unique identifier, the upload ID, that you must include in your upload part request.

For more information about using the UploadPartCopy operation, see the following:

  • For conceptual information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide .
  • For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide .
  • For information about copying objects using a single atomic action vs. a multipart upload, see Operations on Objects in the Amazon S3 User Guide .
  • For information about using server-side encryption with customer-provided encryption keys with the UploadPartCopy operation, see CopyObject and UploadPart .

Note the following additional considerations about the request headers x-amz-copy-source-if-match , x-amz-copy-source-if-none-match , x-amz-copy-source-if-unmodified-since , and x-amz-copy-source-if-modified-since :

  • Consideration 1 - If both of the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows: x-amz-copy-source-if-match condition evaluates to true , and; x-amz-copy-source-if-unmodified-since condition evaluates to false ; Amazon S3 returns 200 OK and copies the data.
  • Consideration 2 - If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows: x-amz-copy-source-if-none-match condition evaluates to false , and; x-amz-copy-source-if-modified-since condition evaluates to true ; Amazon S3 returns 412 Precondition Failed response code.
Versioning

If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the object to copy. If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source , Amazon S3 returns a 404 error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source .

You can optionally specify a specific version of the source object to copy by adding the versionId subresource as shown in the following example:

x-amz-copy-source: /bucket/object?versionId=version id

Parameters
  • Bucket (string) --

    [REQUIRED]

    The bucket name.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • CopySource (str or dict) -- [REQUIRED] The name of the source bucket, key name of the source object, and optional version ID of the source object. You can either provide this value as a string or a dictionary. The string form is {bucket}/{key} or {bucket}/{key}?versionId={versionId} if you want to copy a specific version. You can also provide this value as a dictionary. The dictionary format is recommended over the string format because it is more explicit. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted. To specify an S3 access point, provide the access point ARN for the Bucket key in the copy source dictionary. If you want to provide the copy source for an S3 access point as a string instead of a dictionary, the ARN provided must be the full S3 access point object ARN (i.e. {accesspoint_arn}/object/{key})
  • CopySourceIfMatch (string) -- Copies the object if its entity tag (ETag) matches the specified tag.
  • CopySourceIfModifiedSince (datetime) -- Copies the object if it has been modified since the specified time.
  • CopySourceIfNoneMatch (string) -- Copies the object if its entity tag (ETag) is different than the specified ETag.
  • CopySourceIfUnmodifiedSince (datetime) -- Copies the object if it hasn't been modified since the specified time.
  • CopySourceRange (string) -- The range of bytes to copy from the source object. The range value must use the form bytes=first-last, where the first and last are the zero-based byte offsets to copy. For example, bytes=0-9 indicates that you want to copy the first 10 bytes of the source. You can copy a range only if the source object is greater than 5 MB.
  • Key (string) --

    [REQUIRED]

    Object key for which the multipart upload was initiated.

  • PartNumber (integer) --

    [REQUIRED]

    Part number of part being copied. This is a positive integer between 1 and 10,000.

write_get_object_response(**kwargs)

Passes transformed objects to a GetObject operation when using Object Lambda access points. For information about Object Lambda access points, see Transforming objects with Object Lambda access points in the Amazon S3 User Guide .

This operation supports metadata that can be returned by GetObject , in addition to RequestRoute , RequestToken , StatusCode , ErrorCode , and ErrorMessage . The GetObject response metadata is supported so that the WriteGetObjectResponse caller, typically an Lambda function, can provide the same metadata when it internally invokes GetObject . When WriteGetObjectResponse is called by a customer-owned Lambda function, the metadata returned to the end user GetObject call might differ from what Amazon S3 would normally return.

You can include any number of metadata headers. When including a metadata header, it should be prefaced with x-amz-meta . For example, x-amz-meta-my-custom-header: MyCustomValue . The primary use case for this is to forward GetObject metadata.

Amazon Web Services provides some prebuilt Lambda functions that you can use with S3 Object Lambda to detect and redact personally identifiable information (PII) and decompress S3 objects. These Lambda functions are available in the Amazon Web Services Serverless Application Repository, and can be selected through the Amazon Web Services Management Console when you create your Object Lambda access point.

Example 1: PII Access Control - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically detects personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 2: PII Redaction - This Lambda function uses Amazon Comprehend, a natural language processing (NLP) service using machine learning to find insights and relationships in text. It automatically redacts personally identifiable information (PII) such as names, addresses, dates, credit card numbers, and social security numbers from documents in your Amazon S3 bucket.

Example 3: Decompression - The Lambda function S3ObjectLambdaDecompression, is equipped to decompress objects stored in S3 in one of six compressed file formats including bzip2, gzip, snappy, zlib, zstandard and ZIP.

For information on how to view and use these functions, see Using Amazon Web Services built Lambda functions in the Amazon S3 User Guide .

  • ChecksumCRC32C (string) --

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 32-bit CRC32C checksum of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

    Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

  • ChecksumSHA1 (string) --

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 160-bit SHA-1 digest of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

    Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

  • ChecksumSHA256 (string) --

    This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This specifies the base64-encoded, 256-bit SHA-256 digest of the object returned by the Object Lambda function. This may not match the checksum for the object stored in Amazon S3. Amazon S3 will perform validation of the checksum values only when the original GetObject request required checksum validation. For more information about checksums, see Checking object integrity in the Amazon S3 User Guide .

    Only one checksum header can be specified at a time. If you supply multiple checksum headers, this request will fail.

Paginators

The available paginators are:

class S3.Paginator.ListMultipartUploads
paginator = client.get_paginator('list_multipart_uploads')
paginate(**kwargs)

Creates an iterator that will paginate through responses from S3.Client.list_multipart_uploads().

See also: AWS API Documentation

Request Syntax

response_iterator = paginator.paginate(
    Bucket='string',
    Delimiter='string',
    EncodingType='url',
    Prefix='string',
    ExpectedBucketOwner='string',
    PaginationConfig={
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
    }
)
Parameters
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket to which the multipart upload was initiated.

    When using this action with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide .

    When using this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form `` AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com`` . When using this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using Amazon S3 on Outposts in the Amazon S3 User Guide .

  • Delimiter (string) --

    Character you use to group keys.

    All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes . If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.

  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • Prefix (string) -- Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.)
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • PaginationConfig (dict) --

    A dictionary that provides parameters to control pagination.

    • MaxItems (integer) --

      The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.

    • PageSize (integer) --

      The size of each page.

    • StartingToken (string) --

      A token to specify where to start paginating. This is the NextToken from a previous response.

Response Structure

  • (dict) --

    • IsTruncated (boolean) --

      A flag that indicates whether Amazon S3 returned all of the results that satisfied the search criteria.

    • Marker (string) --

      Indicates where in the bucket listing begins. Marker is included in the response if it was sent with the request.

    • NextMarker (string) --

      When response is truncated (the IsTruncated element value in the response is true), you can use the key name in this field as marker in the subsequent request to get next set of objects. Amazon S3 lists objects in alphabetical order Note: This element is returned only if you have delimiter request parameter specified. If response does not include the NextMarker and it is truncated, you can use the value of the last Key in the response as the marker in the subsequent request to get the next set of object keys.

    • Contents (list) --

      Metadata about each object returned.

      • (dict) --

        An object consists of data and its descriptive metadata.

        • Key (string) --

          The name that you assign to an object. You use the object key to retrieve the object.

        • LastModified (datetime) --

          Creation date of the object.

        • ETag (string) --

          The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

          • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.
          • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.
          • If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.
        • ChecksumAlgorithm (list) --

          The algorithm that was used to create a checksum of the object.

          • (string) --
        • Size (integer) --

          Size in bytes of the object

        • StorageClass (string) --

          The class of storage used to store the object.

        • Owner (dict) --

          The owner of the object

          • DisplayName (string) --

            Container for the display name of the owner.

          • ID (string) --

            Container for the ID of the owner.

    • Name (string) --

      The bucket name.

    • Prefix (string) --

      Keys that begin with the indicated prefix.

    • Delimiter (string) --

      Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.

    • MaxKeys (integer) --

      The maximum number of keys returned in the response body.

    • CommonPrefixes (list) --

      All of the keys (up to 1,000) rolled up in a common prefix count as a single return when calculating the number of returns.

      A response can contain CommonPrefixes only if you specify a delimiter.

      CommonPrefixes contains all (if there are any) keys between Prefix and the next occurrence of the string specified by the delimiter.

      CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix.

      For example, if the prefix is notes/ and the delimiter is a slash (/) as in notes/summer/july, the common prefix is notes/summer/. All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.

      • (dict) --

import boto3

s3 = boto3.resource('s3')

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

create_bucket(**kwargs)

Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules .

If you want to create an Amazon S3 on Outposts bucket, see Create Bucket .

By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket .

Note

If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets .

Access control lists (ACLs)

When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.

Warning

If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide .

There are two ways to grant the appropriate permissions using the request headers.

  • Specify a canned ACL using the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .

  • Specify access permissions explicitly using the x-amz-grant-read , x-amz-grant-write , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"

Note

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Permissions

In addition to s3:CreateBucket , the following permissions are required when your CreateBucket includes specific headers:

  • ACLs - If your CreateBucket request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both s3:CreateBucket and s3:PutBucketAcl permissions are needed. If the ACL the CreateBucket request is private or doesn't specify any ACLs, only s3:CreateBucket permission is needed.
  • Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request, s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
  • S3 Object Ownership - If your CreateBucket request includes the the x-amz-object-ownership header, s3:PutBucketOwnershipControls permission is required.

The following operations are related to CreateBucket :

Parameters
  • ACL (string) -- The canned ACL to apply to the bucket.
  • Bucket (string) --

    [REQUIRED]

    The name of the bucket to create.

  • CreateBucketConfiguration (dict) --

    The configuration information for the bucket.

    • LocationConstraint (string) --

      Specifies the Region where the bucket will be created. If you don't specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1).

  • GrantFullControl (string) -- Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.
  • GrantRead (string) -- Allows grantee to list the objects in the bucket.
  • GrantReadACP (string) -- Allows grantee to read the bucket ACL.
  • GrantWrite (string) --

    Allows grantee to create new objects in the bucket.

    For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.

  • GrantWriteACP (string) -- Allows grantee to write the ACL for the applicable bucket.
  • ObjectLockEnabledForBucket (boolean) -- Specifies whether you want S3 Object Lock to be enabled for the new bucket.
  • ObjectOwnership (string) --

    The container element for object ownership for a bucket's ownership controls.

    BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

    ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

    BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

creation_date
  • (datetime) --

    Date the bucket was created. This date can change when making changes to your bucket, such as editing its bucket policy.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

copy(CopySource, Key, ExtraArgs=None, Callback=None, SourceClient=None, Config=None)

Copy an object from one S3 location to an object in this bucket.

This is a managed transfer which will perform a multipart copy in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'mybucket',
    'Key': 'mykey'
}
bucket = s3.Bucket('otherbucket')
bucket.copy(copy_source, 'otherkey')
Parameters
  • CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
  • Key (str) -- The name of the key to copy to
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the copy.
  • SourceClient (botocore or boto3 Client) -- The client to be used for operation that may happen at the source object. For example, this client is used for the head_object that determines the size of the copy. If no client is provided, the current client is used as the client for the source object.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the copy.
create(**kwargs)

Creates a new S3 bucket. To create a bucket, you must register with Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.

Not every string is an acceptable bucket name. For information about bucket naming restrictions, see Bucket naming rules .

If you want to create an Amazon S3 on Outposts bucket, see Create Bucket .

By default, the bucket is created in the US East (N. Virginia) Region. You can optionally specify a Region in the request body. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket .

Note

If you send your create bucket request to the s3.amazonaws.com endpoint, the request goes to the us-east-1 Region. Accordingly, the signature calculations in Signature Version 4 must use us-east-1 as the Region, even if the location constraint in the request specifies another Region where the bucket is to be created. If you create a bucket in a Region other than US East (N. Virginia), your application must be able to handle 307 redirect. For more information, see Virtual hosting of buckets .

Access control lists (ACLs)

When creating a bucket using this operation, you can optionally configure the bucket ACL to specify the accounts or groups that should be granted specific permissions on the bucket.

Warning

If your CreateBucket request sets bucket owner enforced for S3 Object Ownership and specifies a bucket ACL that provides access to an external Amazon Web Services account, your request fails with a 400 error and returns the InvalidBucketAclWithObjectOwnership error code. For more information, see Controlling object ownership in the Amazon S3 User Guide .

There are two ways to grant the appropriate permissions using the request headers.

  • Specify a canned ACL using the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .

  • Specify access permissions explicitly using the x-amz-grant-read , x-amz-grant-write , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These headers map to the set of permissions Amazon S3 supports in an ACL. For more information, see Access control list (ACL) overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"

Note

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Permissions

In addition to s3:CreateBucket , the following permissions are required when your CreateBucket includes specific headers:

  • ACLs - If your CreateBucket request specifies ACL permissions and the ACL is public-read, public-read-write, authenticated-read, or if you specify access permissions explicitly through any other ACL, both s3:CreateBucket and s3:PutBucketAcl permissions are needed. If the ACL the CreateBucket request is private or doesn't specify any ACLs, only s3:CreateBucket permission is needed.
  • Object Lock - If ObjectLockEnabledForBucket is set to true in your CreateBucket request, s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
  • S3 Object Ownership - If your CreateBucket request includes the the x-amz-object-ownership header, s3:PutBucketOwnershipControls permission is required.

    GrantWrite='string',
    GrantWriteACP='string',
    ObjectLockEnabledForBucket=True|False,
    ObjectOwnership='BucketOwnerPreferred'|'ObjectWriter'|'BucketOwnerEnforced'
)
Parameters
  • ACL (string) -- The canned ACL to apply to the bucket.
  • CreateBucketConfiguration (dict) --

    The configuration information for the bucket.

    • LocationConstraint (string) --

      Specifies the Region where the bucket will be created. If you don't specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1).

  • GrantFullControl (string) -- Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.
  • GrantRead (string) -- Allows grantee to list the objects in the bucket.
  • GrantReadACP (string) -- Allows grantee to read the bucket ACL.
  • GrantWrite (string) --

    Allows grantee to create new objects in the bucket.

    For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.

  • GrantWriteACP (string) -- Allows grantee to write the ACL for the applicable bucket.
  • ObjectLockEnabledForBucket (boolean) -- Specifies whether you want S3 Object Lock to be enabled for the new bucket.
  • ObjectOwnership (string) --

    The container element for object ownership for a bucket's ownership controls.

    BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.

    ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.

    BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

Request Syntax

response = bucket.delete(
    ExpectedBucketOwner='string'
)
Parameters
ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns
None
delete_objects(**kwargs)

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete .

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

    • Objects (list) -- [REQUIRED]

      The objects to delete.

      • (dict) --

        Object Identifier is unique value to identify objects.

        • Key (string) -- [REQUIRED]

          Key name of the object.

          Warning

          Replacement must be made for object keys containing special characters (such as carriage returns) when using XML requests. For more information, see XML related object key constraints .

        • VersionId (string) --

          VersionId for the specific version of the object to delete.

    • Quiet (boolean) --

      Element to enable quiet mode for the request. When you add this element, you must set its value to true.

  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.

download_file(Key, Filename, ExtraArgs=None, Callback=None, Config=None)

Download an S3 object to a file.

Usage:

import boto3
s3 = boto3.resource('s3')
s3.Bucket('mybucket').download_file('hello.txt', '/tmp/hello.txt')

Similar behavior as S3Transfer's download_file() method, except that parameters are capitalized. Detailed examples can be found at S3Transfer's Usage.

Parameters
  • Key (str) -- The name of the key to download from.
  • Filename (str) -- The path to the file to download to.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the download.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the transfer.
download_fileobj(Key, Fileobj, ExtraArgs=None, Callback=None, Config=None)

Download an object from this bucket to a file-like-object.

The file-like object must be in binary mode.

This is a managed transfer which will perform a multipart download in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')

with open('filename', 'wb') as data:
    bucket.download_fileobj('mykey', data)
Parameters
  • Fileobj (a file-like object) -- A file-like object to download into. At a minimum, it must implement the write method and must accept bytes.
  • Key (str) -- The name of the key to download from.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the download.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the download.
get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load(*args, **kwargs)

Calls s3.Client.list_buckets() to update the attributes of the Bucket resource.

put_object(**kwargs)

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.

To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

Note

  • To successfully complete the PutObject request, you must have the s3:PutObject in your IAM permissions.
  • To successfully change the objects acl of your PutObject request, you must have the s3:PutObjectAcl in your IAM permissions.
  • The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide .

Server-side Encryption

You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption .

If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported .

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Storage Class Options

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.

For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

Parameters
  • ACL (string) --

    The canned ACL to apply to the object. For more information, see Canned ACL .

    This action is not supported by Amazon S3 on Outposts.

  • Body (bytes or seekable file-like object) -- Object data.
  • CacheControl (string) -- Can be used to specify caching behavior along the request/reply chain. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.9 .
  • ContentDisposition (string) -- Specifies presentational information for the object. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html#sec19.5.1 .
  • ContentEncoding (string) -- Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.11 .
  • ContentLanguage (string) -- The language the content is in.
  • ContentLength (integer) -- Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.13 .
  • ContentMD5 (string) -- The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication .
  • ContentType (string) -- A standard MIME type describing the format of the contents. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17 .

  • ChecksumSHA1 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 160-bit SHA-1 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ChecksumSHA256 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 256-bit SHA-256 digest of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • Expires (datetime) -- The date and time at which the object is no longer cacheable. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.21 .
  • GrantFullControl (string) --

    Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

    This action is not supported by Amazon S3 on Outposts.

  • GrantRead (string) --

    Allows grantee to read the object data and its metadata.

    This action is not supported by Amazon S3 on Outposts.

  • GrantReadACP (string) --

    Allows grantee to read the object ACL.

    This action is not supported by Amazon S3 on Outposts.

  • GrantWriteACP (string) --

    Allows grantee to write the ACL for the applicable object.

    This action is not supported by Amazon S3 on Outposts.

  • Key (string) --

    [REQUIRED]

    Object key for which the PUT action was initiated.

  • Metadata (dict) --

    A map of metadata to store with the object in S3.

    • (string) --
      • (string) --
  • ServerSideEncryption (string) -- The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
  • StorageClass (string) -- By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .
  • WebsiteRedirectLocation (string) --

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata .

    In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

    x-amz-website-redirect-location: /anotherPage.html

    In the following example, the request header sets the object redirect to another website:

    x-amz-website-redirect-location: http://www.example.com/

    For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects .

  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • SSEKMSKeyId (string) -- If x-amz-server-side-encryption is present and has the value of aws:kms , this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetrical customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms , but do not provide``x-amz-server-side-encryption-aws-kms-key-id`` , Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.
  • SSEKMSEncryptionContext (string) -- Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
  • BucketKeyEnabled (boolean) --

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • Tagging (string) -- The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, "Key1=Value1")
  • ObjectLockMode (string) -- The Object Lock mode that you want to apply to this object.
  • ObjectLockRetainUntilDate (datetime) -- The date and time when you want this object's Object Lock to expire. Must be formatted as a timestamp parameter.
  • ObjectLockLegalHoldStatus (string) -- Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Collections

Collections provide an interface to iterate over and manipulate groups of resources. For more information about collections refer to the Resources Introduction Guide.

multipart_uploads

A collection of MultipartUpload resources.A MultipartUpload Collection will include all resources by default, and extreme caution should be taken when performing actions on all resources.

all()

Creates an iterable of all MultipartUpload resources in the collection.

See also: AWS API Documentation

Request Syntax

multipart_upload_iterator = bucket.multipart_uploads.all()
Return type
list(s3.MultipartUpload)
Returns
A list of MultipartUpload resources
filter(**kwargs)

Creates an iterable of all MultipartUpload resources in the collection filtered by kwargs passed to method. A MultipartUpload collection will include all resources by default if no filters are provided, and extreme caution should be taken when performing actions on all resources.

See also: AWS API Documentation

Request Syntax

multipart_upload_iterator = bucket.multipart_uploads.filter(
    Delimiter='string',
    EncodingType='url',
    KeyMarker='string',
    MaxUploads=123,
    Prefix='string',
    UploadIdMarker='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Delimiter (string) --

    Character you use to group keys.

    All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes . If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.

  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • KeyMarker (string) --

    Together with upload-id-marker, this parameter specifies the multipart upload after which listing should begin.

    If upload-id-marker is not specified, only the keys lexicographically greater than the specified key-marker will be included in the list.

    If upload-id-marker is specified, any multipart uploads for a key equal to the key-marker might also be included, provided those multipart uploads have upload IDs lexicographically greater than the specified upload-id-marker .

  • MaxUploads (integer) -- Sets the maximum number of multipart uploads, from 1 to 1,000, to return in the response body. 1,000 is the maximum number of uploads that can be returned in a response.
  • Prefix (string) -- Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.)
  • UploadIdMarker (string) -- Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored. Otherwise, any multipart uploads for a key equal to the key-marker might be included in the list only if they have an upload ID lexicographically greater than the specified upload-id-marker .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Return type

list(s3.MultipartUpload)

)
Parameters
count (integer) -- The number of items returned by each service call
Return type

object_versions

A collection of ObjectVersion resources.A ObjectVersion Collection will include all resources by default, and extreme caution should be taken when performing actions on all resources.

all()

Creates an iterable of all ObjectVersion resources in the collection.

See also: AWS API Documentation

Request Syntax

object_version_iterator = bucket.object_versions.all()
Return type
list(s3.ObjectVersion)
Returns
A list of ObjectVersion resources
delete(**kwargs)

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete .

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

The following operations are related to DeleteObjects :

See also: AWS API Documentation

Request Syntax

response = bucket.object_versions.delete(
    MFA='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string',
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256'
)
Parameters
  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

          The error message contains a generic description of the error condition in English. It is intended for a human audience. Simple programs display the message directly to the end user if they encounter an error condition they don't know how or don't care to handle. Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.

filter(**kwargs)

Creates an iterable of all ObjectVersion resources in the collection filtered by kwargs passed to method. A ObjectVersion collection will include all resources by default if no filters are provided, and extreme caution should be taken when performing actions on all resources.

See also: AWS API Documentation

Request Syntax

object_version_iterator = bucket.object_versions.filter(
    Delimiter='string',
    EncodingType='url',
    KeyMarker='string',
    MaxKeys=123,
    Prefix='string',
    VersionIdMarker='string',
    ExpectedBucketOwner='string'
)
Parameters
  • Delimiter (string) -- A delimiter is a character that you specify to group keys. All keys that contain the same string between the prefix and the first occurrence of the delimiter are grouped under a single result element in CommonPrefixes. These groups are counted as one result against the max-keys limitation. These keys are not returned elsewhere in the response.
  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • KeyMarker (string) -- Specifies the key to start with when listing objects in a bucket.
  • MaxKeys (integer) -- Sets the maximum number of keys returned in the response. By default the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more. If additional keys satisfy the search criteria, but were not returned because max-keys was exceeded, the response contains <isTruncated>true</isTruncated>. To return the additional keys, see key-marker and version-id-marker.
  • Prefix (string) -- Use this parameter to select only those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.) You can use prefix with delimiter to roll up numerous objects into a single result under CommonPrefixes.
  • VersionIdMarker (string) -- Specifies the object version you want to start listing from.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Request Syntax

object_summary_iterator = bucket.objects.all()
Return type
list(s3.ObjectSummary)
Returns
A list of ObjectSummary resources
delete(**kwargs)

This action enables you to delete multiple objects from a bucket using a single HTTP request. If you know the object keys that you want to delete, then this action provides a suitable alternative to sending individual delete requests, reducing per-request overhead.

The request contains a list of up to 1000 keys that you want to delete. In the XML, you provide the object key names, and optionally, version IDs if you want to delete a specific version of the object from a versioning-enabled bucket. For each key, Amazon S3 performs a delete action and returns the result of that delete, success, or failure, in the response. Note that if the object specified in the request is not found, Amazon S3 returns the result as deleted.

The action supports two modes for the response: verbose and quiet. By default, the action uses verbose mode in which the response includes the result of deletion of each key in your request. In quiet mode the response includes only keys where the delete action encountered an error. For a successful deletion, the action does not return any information about the delete in the response body.

When performing this action on an MFA Delete enabled bucket, that attempts to delete any versioned objects, you must include an MFA token. If you do not provide one, the entire request will fail, even if there are non-versioned objects you are trying to delete. If you provide an invalid token, whether there are versioned keys in the request or not, the entire Multi-Object Delete request will fail. For information about MFA Delete, see MFA Delete .

Finally, the Content-MD5 header is required for all Multi-Object Delete requests. Amazon S3 uses the header value to ensure that your request body has not been altered in transit.

The following operations are related to DeleteObjects :

See also: AWS API Documentation

Request Syntax

response = bucket.objects.delete(
    MFA='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string',
    ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256'
)
Parameters
  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Specifies whether you want to delete this object even if it has a Governance-type Object Lock in place. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

    This checksum algorithm must be the same for all parts and it match the checksum value supplied in the CreateMultipartUpload request.

Simple programs display the message directly to the end user if they encounter an error condition they don't know how or don't care to handle. Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.

filter(**kwargs)

Creates an iterable of all ObjectSummary resources in the collection filtered by kwargs passed to method. A ObjectSummary collection will include all resources by default if no filters are provided, and extreme caution should be taken when performing actions on all resources.

See also: AWS API Documentation

Request Syntax

object_summary_iterator = bucket.objects.filter(
    Delimiter='string',
    EncodingType='url',
    Marker='string',
    MaxKeys=123,
    Prefix='string',
    RequestPayer='requester',
    ExpectedBucketOwner='string'
)
Parameters
  • Delimiter (string) -- A delimiter is a character you use to group keys.
  • EncodingType (string) -- Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
  • Marker (string) -- Marker is where you want Amazon S3 to start listing from. Amazon S3 starts listing after this specified key. Marker can be any key in the bucket.
  • MaxKeys (integer) -- Sets the maximum number of keys returned in the response. By default the action returns up to 1,000 key names. The response might contain fewer keys but will never contain more.
  • Prefix (string) -- Limits the response to keys that begin with the specified prefix.
  • RequestPayer (string) -- Confirms that the requester knows that she or he will be charged for the list objects request. Bucket owners need not specify this parameter in their requests.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load()

Calls S3.Client.get_bucket_acl() to update the attributes of the BucketAcl resource. Note that the load and reload methods are the same method and can be used interchangeably.

See also: AWS API Documentation

Request Syntax

bucket_acl.load()
Returns
None
put(**kwargs)

Sets the permissions on an existing bucket using access control lists (ACL). For more information, see Using ACLs . To set the ACL of a bucket, you must have WRITE_ACP permission.

You can use one of the following two ways to set a bucket's permissions:

  • Specify the ACL in the request body
  • Specify permissions using request headers

Note

You cannot specify access permission using both the body and the request headers.

Depending on your application needs, you may choose to set the ACL on a bucket using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, then you can continue to use that approach.

Warning

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide .

Access Permissions

You can set access permissions using one of the following methods:

  • Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-acl . If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL .

  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use the x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-write header grants create, overwrite, and delete objects permission to LogDelivery group predefined by Amazon S3 and two Amazon Web Services accounts identified by their email addresses.

x-amz-grant-write: uri="http://acs.amazonaws.com/groups/s3/LogDelivery", id="111122223333", id="555566667777"

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>lt;/Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

See also: AWS API Documentation

Request Syntax

bucket_cors.load()
Returns
None
put(**kwargs)

Sets the cors configuration for your bucket. If the configuration exists, Amazon S3 replaces it.

To use this operation, you must be allowed to perform the s3:PutBucketCORS action. By default, the bucket owner has this permission and can grant it to others.

You set this configuration on a bucket so that the bucket can service cross-origin requests. For example, you might want to enable a request whose origin is http://www.example.com to access your Amazon S3 bucket at my.example.bucket.com by using the browser's XMLHttpRequest capability.

To enable cross-origin resource sharing (CORS) on a bucket, you add the cors subresource to the bucket. The cors subresource is an XML document in which you configure rules that identify origins and the HTTP methods that can be executed on your bucket. The document is limited to 64 KB in size.

When Amazon S3 receives a cross-origin request (or a pre-flight OPTIONS request) against a bucket, it evaluates the cors configuration on the bucket and uses the first CORSRule rule that matches the incoming browser request to enable a cross-origin request. For a rule to match, the following conditions must be met:

  • The request's Origin header must match AllowedOrigin elements.
  • The request method (for example, GET, PUT, HEAD, and so on) or the Access-Control-Request-Method header in case of a pre-flight OPTIONS request must be one of the AllowedMethod elements.
  • Every header specified in the Access-Control-Request-Headers request header of a pre-flight request must match an AllowedHeader element.

For more information about CORS, go to Enabling Cross-Origin Resource Sharing in the Amazon S3 User Guide .

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

delete(**kwargs)

Deletes the lifecycle configuration from the specified bucket. Amazon S3 removes all the lifecycle configuration rules in the lifecycle subresource associated with the bucket. Your objects never expire, and Amazon S3 no longer automatically deletes any objects on the basis of rules contained in the deleted lifecycle configuration.

To use this operation, you must have permission to perform the s3:PutLifecycleConfiguration action. By default, the bucket owner has this permission and the bucket owner can grant this permission to others.

There is usually some time lag before lifecycle configuration deletion is fully propagated to all the Amazon S3 systems.

For more information about the object expiration, see Elements to Describe Lifecycle Actions .

Parameters
ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Returns
None
get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load()

Calls S3.Client.get_bucket_lifecycle() to update the attributes of the BucketLifecycle resource. Note that the load and reload methods are the same method and can be used interchangeably.

put(**kwargs)

Warning

For an updated version of this API, see PutBucketLifecycleConfiguration . This version has been deprecated. Existing lifecycle configurations will work. For new lifecycle configurations, use the updated API.

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. For information about lifecycle configuration, see Object Lifecycle Management in the Amazon S3 User Guide .

By default, all Amazon S3 resources, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration) are private. Only the resource owner, the Amazon Web Services account that created the resource, can access it. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, users must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. Explicit denial also supersedes any other permissions. If you want to prevent users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

  • s3:DeleteObject
  • s3:DeleteObjectVersion
  • s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to your Amazon S3 Resources in the Amazon S3 User Guide .

For more examples of transitioning objects to storage classes such as STANDARD_IA or ONEZONE_IA, see Examples of Lifecycle Configuration .

Danger

This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.

Request Syntax

bucket_lifecycle_configuration.load()
Returns
None
put(**kwargs)

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle .

Note

Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, or a combination of both. Accordingly, this section describes the latest API. The previous version of the API supported filtering based only on an object key name prefix, which is supported for backward compatibility. For the related API description, see PutBucketLifecycle .

You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:

  • Filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, or a combination of both.
  • Status whether the rule is in effect.
  • One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements .

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. Explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

  • s3:DeleteObject
  • s3:DeleteObjectVersion
  • s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources .

See also: AWS API Documentation

Request Syntax

bucket_logging.load()
Returns
None
put(**kwargs)

Set the logging parameters for a bucket and to specify permissions for who can view and modify the logging parameters. All logs are saved to buckets in the same Amazon Web Services Region as the source bucket. To set the logging status of a bucket, you must be the bucket owner.

The bucket owner is automatically granted FULL_CONTROL to all logs. You use the Grantee request element to grant access to other people. The Permissions request element specifies the kind of access the grantee has to the logs.

Warning

If the target bucket for log delivery uses the bucket owner enforced setting for S3 Object Ownership, you can't use the Grantee request element to grant access to others. Permissions can only be granted using policies. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide .

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request.
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress></Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>

To enable logging, you use LoggingEnabled and its children request elements. To disable logging, you use an empty BucketLoggingStatus request element:

<BucketLoggingStatus xmlns="http://doc.s3.amazonaws.com/2006-03-01" />

For more information about server access logging, see Server Access Logging in the Amazon S3 User Guide .

For more information about creating a bucket, see CreateBucket . For more information about returning the logging status of a bucket, see GetBucketLogging .

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load()

Calls S3.Client.get_bucket_notification_configuration() to update the attributes of the BucketNotification resource. Note that the load and reload methods are the same method and can be used interchangeably.

See also: AWS API Documentation

Request Syntax

bucket_notification.load()
Returns
None
put(**kwargs)

Enables notifications of specified events for a bucket. For more information about event notifications, see Configuring Event Notifications .

Using this API, you can replace an existing notification configuration. The configuration is an XML file that defines the event types that you want Amazon S3 to publish and the destination where you want Amazon S3 to publish an event notification when it detects an event of the specified type.

By default, your bucket has no event notifications configured. That is, the notification configuration will be an empty NotificationConfiguration .

<NotificationConfiguration>

</NotificationConfiguration>

This action replaces the existing notification configuration with the configuration you include in the request body.

After Amazon S3 receives this request, it first verifies that any Amazon Simple Notification Service (Amazon SNS) or Amazon Simple Queue Service (Amazon SQS) destination exists, and that the bucket owner has permission to publish to it by sending a test notification. In the case of Lambda destinations, Amazon S3 verifies that the Lambda function permissions grant Amazon S3 permission to invoke the function from the Amazon S3 bucket. For more information, see Configuring Notifications for Amazon S3 Events .

You can disable notifications by adding the empty NotificationConfiguration element.

For more information about the number of event notification configurations that you can create per bucket, see Amazon S3 service quotas in Amazon Web Services General Reference .

By default, only the bucket owner can configure notifications on a bucket. However, bucket owners can use a bucket policy to grant permission to other users to set this configuration with s3:PutBucketNotification permission.

Note

The PUT notification is an atomic operation. For example, suppose your notification configuration includes SNS topic, SQS queue, and Lambda function configurations. When you send a PUT request with this configuration, Amazon S3 sends test messages to your SNS topic. If the message fails, the entire PUT action will fail, and Amazon S3 will not add the configuration to your bucket.

Responses

If the configuration in the request body includes only one TopicConfiguration specifying only the s3:ReducedRedundancyLostObject event type, the response will also include the x-amz-sns-test-message-id header containing the message ID of the test notification sent to the topic.

The following action is related to PutBucketNotificationConfiguration :

Sub-resources

Sub-resources are methods that create a new instance of a child resource. This resource's identifiers get passed along to the child. For more information about sub-resources refer to the Resources Introduction Guide.

Bucket()

Creates a Bucket resource.:

bucket = bucket_notification.Bucket()
Return type
S3.Bucket
Returns
A Bucket resource

BucketPolicy

class S3.BucketPolicy(bucket_name)

A resource representing an Amazon Simple Storage Service (S3) BucketPolicy:

import boto3

s3 = boto3.resource('s3')
bucket_policy = s3.BucketPolicy('bucket_name')
Parameters
bucket_name (string) -- The BucketPolicy's bucket_name identifier. This must be set.

These are the resource's available identifiers:

These are the resource's available attributes:

These are the resource's available actions:

These are the resource's available sub-resources:

Identifiers

Identifiers are properties of a resource that are set upon instantiation of the resource. For more information about identifiers refer to the Resources Introduction Guide.

bucket_name

(string) The BucketPolicy's bucket_name identifier. This must be set.

Attributes

Attributes provide access to the properties of a resource. Attributes are lazy-loaded the first time one is accessed via the load() method. For more information about attributes refer to the Resources Introduction Guide.

policy
  • (string) --

    The bucket policy as a JSON document.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

delete(**kwargs)

This implementation of the DELETE action uses the policy subresource to delete the policy of a specified bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the DeleteBucketPolicy permissions on the specified bucket and belong to the bucket owner's account to use this operation.

If you don't have DeleteBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

Warning

As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

For more information about bucket policies, see Using Bucket Policies and UserPolicies .

If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the PutBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.

Warning

As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.

For more information, see Bucket policy examples .

mfa_delete
  • (string) --

    Specifies whether MFA delete is enabled in the bucket versioning configuration. This element is only returned if the bucket has been configured with MFA delete. If the bucket has never been so configured, this element is not returned.

status
  • (string) --

    The versioning state of the bucket.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

enable(**kwargs)

Sets the versioning state of an existing bucket.

You can set the versioning state with one of the following values:

Enabled —Enables versioning for the objects in the bucket. All objects added to the bucket receive a unique version ID.

Suspended —Disables versioning for the objects in the bucket. All objects added to the bucket receive the version ID null.

If the versioning state has never been set on a bucket, it has no versioning state; a GetBucketVersioning request does not return a versioning state value.

In order to enable MFA Delete, you must be the bucket owner. If you are the bucket owner and want to enable MFA Delete in the bucket versioning configuration, you must include the x-amz-mfa request header and the Status and the MfaDelete request elements in a request to set the versioning state of the bucket.

Warning

If you have an object expiration lifecycle policy in your non-versioned bucket and you want to maintain the same permanent delete behavior when you enable versioning, you must add a noncurrent expiration policy. The noncurrent expiration lifecycle policy will manage the deletes of the noncurrent object versions in the version-enabled bucket. (A version-enabled bucket maintains one current and zero or more noncurrent object versions.) For more information, see Lifecycle and Versioning .

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

delete(**kwargs)

This action removes the website configuration for a bucket. Amazon S3 returns a 200 OK response upon successfully deleting a website configuration on the specified bucket. You will get a 200 OK response if the website configuration you are trying to delete does not exist on the bucket. Amazon S3 returns a 404 response if the bucket specified in the request does not exist.

This DELETE action requires the S3:DeleteBucketWebsite permission. By default, only the bucket owner can delete the website configuration attached to a bucket. However, bucket owners can grant other users permission to delete the website configuration by writing a bucket policy granting them the S3:DeleteBucketWebsite permission.

For more information about hosting websites, see Hosting Websites on Amazon S3 .

To configure a bucket as a website, you can add this subresource on the bucket with website configuration information such as the file name of the index document and any redirect rules. For more information, see Hosting Websites on Amazon S3 .

This PUT action requires the S3:PutBucketWebsite permission. By default, only the bucket owner can configure the website attached to a bucket; however, bucket owners can allow other users to set the website configuration by writing a bucket policy that grants them the S3:PutBucketWebsite permission.

To redirect all website requests sent to the bucket's website endpoint, you add a website configuration with the following elements. Because all requests are sent to another website, you don't need to provide index document name for the bucket.

  • WebsiteConfiguration
  • RedirectAllRequestsTo
  • HostName
  • Protocol

If you want granular control over redirects, you can use the following elements to add routing rules that describe conditions for redirecting requests and information about the redirect destination. In this case, the website configuration must provide an index document for the bucket, because some requests might not be redirected.

  • WebsiteConfiguration
  • IndexDocument
  • Suffix
  • ErrorDocument
  • Key
  • RoutingRules
  • RoutingRule
  • Condition
  • HttpErrorCodeReturnedEquals
  • KeyPrefixEquals
  • Redirect
  • Protocol
  • HostName
  • ReplaceKeyPrefixWith
  • ReplaceKeyWith
  • HttpRedirectCode

Amazon S3 has a limitation of 50 routing rules per website configuration. If you require more than 50 routing rules, you can use object redirect. For more information, see Configuring an Object Redirect in the Amazon S3 User Guide .

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

abort(**kwargs)

This action aborts a multipart upload. After a multipart upload is aborted, no additional parts can be uploaded using that upload ID. The storage consumed by any previously uploaded parts will be freed. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.

To verify that all parts have been removed, so you don't get charged for the part storage, you should call the ListParts action and ensure that the parts list is empty.

For information about permissions required to use the multipart upload, see Multipart Upload and Permissions .

The following operations are related to AbortMultipartUpload :

See also: AWS API Documentation

Request Syntax

response = multipart_upload.abort(
    RequestPayer='requester',
    ExpectedBucketOwner='string'
)
Parameters
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Return type

dict

Returns

Response Syntax

{
    'RequestCharged': 'requester'
}

Response Structure

  • (dict) --

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

complete(**kwargs)

Completes a multipart upload by assembling previously uploaded parts.

You first initiate the multipart upload and then upload all parts using the UploadPart operation. After successfully uploading all relevant parts of an upload, you call this action to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure that the parts list is complete. This action concatenates the parts that you provide in the list. For each part in the list, you must provide the part number and the ETag value, returned after that part was uploaded.

Processing of a Complete Multipart Upload request could take several minutes to complete. After Amazon S3 begins processing the request, it sends an HTTP response header that specifies a 200 OK response. While processing is in progress, Amazon S3 periodically sends white space characters to keep the connection from timing out. Because a request could fail after the initial 200 OK response has been sent, it is important that you check the response body to determine whether the request succeeded.

Note that if CompleteMultipartUpload fails, applications should be prepared to retry the failed requests. For more information, see Amazon S3 Error Best Practices .

Warning

You cannot use Content-Type: application/x-www-form-urlencoded with Complete Multipart Upload requests. Also, if you do not provide a Content-Type header, CompleteMultipartUpload returns a 200 OK response.

For more information about multipart uploads, see Uploading Objects Using Multipart Upload .

For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions .

CompleteMultipartUpload has the following special errors:
  • Error code: EntityTooSmall
    • Description: Your proposed upload is smaller than the minimum allowed object size. Each part must be at least 5 MB in size, except the last part.
    • 400 Bad Request
  • Error code: InvalidPart
    • Description: One or more of the specified parts could not be found. The part might not have been uploaded, or the specified entity tag might not have matched the part's entity tag.
    • 400 Bad Request
  • Error code: InvalidPartOrder
    • Description: The list of parts was not in ascending order. The parts list must be specified in order by part number.
    • 400 Bad Request
  • Error code: NoSuchUpload
    • Description: The specified multipart upload does not exist. The upload ID might be invalid, or the multipart upload might have been aborted or completed.
    • 404 Not Found

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

copy_from(**kwargs)

Uploads a part by copying data from an existing object as data source. You specify the data source by adding the request header x-amz-copy-source in your request and a byte range by adding the request header x-amz-copy-source-range in your request.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide .

Note

Instead of using an existing object as part data, you might use the UploadPart action and provide data in your request.

You must initiate a multipart upload before you can upload any part. In response to your initiate request. Amazon S3 returns a unique identifier, the upload ID, that you must include in your upload part request.

For more information about using the UploadPartCopy operation, see the following:

  • For conceptual information about multipart uploads, see Uploading Objects Using Multipart Upload in the Amazon S3 User Guide .
  • For information about permissions required to use the multipart upload API, see Multipart Upload and Permissions in the Amazon S3 User Guide .
  • For information about copying objects using a single atomic action vs. a multipart upload, see Operations on Objects in the Amazon S3 User Guide .
  • For information about using server-side encryption with customer-provided encryption keys with the UploadPartCopy operation, see CopyObject and UploadPart .

Note the following additional considerations about the request headers x-amz-copy-source-if-match , x-amz-copy-source-if-none-match , x-amz-copy-source-if-unmodified-since , and x-amz-copy-source-if-modified-since :

  • Consideration 1 - If both of the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request as follows: x-amz-copy-source-if-match condition evaluates to true , and; x-amz-copy-source-if-unmodified-since condition evaluates to false ; Amazon S3 returns 200 OK and copies the data.
  • Consideration 2 - If both of the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request as follows: x-amz-copy-source-if-none-match condition evaluates to false , and; x-amz-copy-source-if-modified-since condition evaluates to true ; Amazon S3 returns 412 Precondition Failed response code.
Versioning

If your bucket has versioning enabled, you could have multiple versions of the same object. By default, x-amz-copy-source identifies the current version of the object to copy. If the current version is a delete marker and you don't specify a versionId in the x-amz-copy-source , Amazon S3 returns a 404 error, because the object does not exist. If you specify versionId in the x-amz-copy-source and the versionId is a delete marker, Amazon S3 returns an HTTP 400 error, because you are not allowed to specify a delete marker as a version for the x-amz-copy-source .

You can optionally specify a specific version of the source object to copy by adding the versionId subresource as shown in the following example:

x-amz-copy-source: /bucket/object?versionId=version id

)
Parameters
  • CopySource (str or dict) -- [REQUIRED] The name of the source bucket, key name of the source object, and optional version ID of the source object. You can either provide this value as a string or a dictionary. The string form is {bucket}/{key} or {bucket}/{key}?versionId={versionId} if you want to copy a specific version. You can also provide this value as a dictionary. The dictionary format is recommended over the string format because it is more explicit. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted. To specify an S3 access point, provide the access point ARN for the Bucket key in the copy source dictionary. If you want to provide the copy source for an S3 access point as a string instead of a dictionary, the ARN provided must be the full S3 access point object ARN (i.e. {accesspoint_arn}/object/{key})
  • CopySourceIfMatch (string) -- Copies the object if its entity tag (ETag) matches the specified tag.
  • CopySourceIfModifiedSince (datetime) -- Copies the object if it has been modified since the specified time.
  • CopySourceIfNoneMatch (string) -- Copies the object if its entity tag (ETag) is different than the specified ETag.
  • CopySourceIfUnmodifiedSince (datetime) -- Copies the object if it hasn't been modified since the specified time.
  • CopySourceRange (string) -- The range of bytes to copy from the source object. The range value must use the form bytes=first-last, where the first and last are the zero-based byte offsets to copy. For example, bytes=0-9 indicates that you want to copy the first 10 bytes of the source. You can copy a range only if the source object is greater than 5 MB.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header. This must be the same encryption key specified in the initiate multipart upload request.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • CopySourceSSECustomerAlgorithm (string) -- Specifies the algorithm to use when decrypting the source object (for example, AES256).
  • CopySourceSSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.
  • CopySourceSSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • ExpectedBucketOwner (string) -- The account ID of the expected destination bucket owner. If the destination bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ExpectedSourceBucketOwner (string) -- The account ID of the expected source bucket owner. If the source bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

upload(**kwargs)

Uploads a part in a multipart upload.

Note

In this operation, you provide part data in your request. However, you have an option to specify your existing Amazon S3 object as a data source for the part you are uploading. To upload a part from an existing object, you use the UploadPartCopy operation.

You must initiate a multipart upload (see CreateMultipartUpload ) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier, that you must include in your upload part request.

Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten.

For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide .

To ensure that data is not corrupted when traversing the network, specify the Content-MD5 header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error.

If the upload request is signed with Signature Version 4, then Amazon Web Services S3 uses the x-amz-content-sha256 header as a checksum instead of Content-MD5 . For more information see Authenticating Requests: Using the Authorization Header (Amazon Web Services Signature Version 4) .

Note: After you initiate multipart upload and upload one or more parts, you must either complete or abort multipart upload in order to stop getting charged for storage of the uploaded parts. Only after you either complete or abort multipart upload, Amazon S3 frees up the parts storage and stops charging you for the parts storage.

For more information on multipart uploads, go to Multipart Upload Overview in the Amazon S3 User Guide .

For information on the permissions required to use the multipart upload API, go to Multipart Upload and Permissions in the Amazon S3 User Guide .

You can optionally request server-side encryption where Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it for you when you access it. You have the option of providing your own encryption key, or you can use the Amazon Web Services managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in the request must match the headers you used in the request to initiate the upload by using CreateMultipartUpload . For more information, go to Using Server-Side Encryption in the Amazon S3 User Guide .

Server-side encryption is supported by the S3 Multipart Upload actions. Unless you are using a customer-provided encryption key, you don't need to specify the encryption parameters in each UploadPart request. Instead, you only need to specify the server-side encryption parameters in the initial Initiate Multipart request. For more information, see CreateMultipartUpload .

If you requested server-side encryption using a customer-provided encryption key in your initiate multipart upload request, you must provide identical encryption information in each part upload using the following headers.

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

replication_status
  • (string) --

    Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

    In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (GetObject ) or object metadata (HeadObject ) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:

    • If requesting an object from the source bucket , Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs . Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf , are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
    • If requesting an object from a destination bucket , Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.
    • When replicating objects to multiple destination buckets , the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

    For more information, see Replication .

request_charged
  • (string) --

    If present, indicates that the requester was successfully charged for the request.

restore
  • (string) --

    If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.

    If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:

    x-amz-restore: ongoing-request="false", expiry-date="Fri, 21 Dec 2012 00:00:00 GMT"

    If the object restoration is in progress, the header returns the value ongoing-request="true" .

    For more information about archiving objects, see Transitioning Objects: General Considerations .

server_side_encryption
  • (string) --

    If the object is stored using server-side encryption either with an Amazon Web Services KMS key or an Amazon S3-managed encryption key, the response includes this header with the value of the server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).

sse_customer_algorithm
  • (string) --

    If server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.

sse_customer_key_md5
  • (string) --

    If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.

ssekms_key_id
  • (string) --

    If present, specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetric customer managed key that was used for the object.

storage_class
  • (string) --

    Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.

    For more information, see Storage Classes .

version_id
  • (string) --

    Version of the object.

website_redirect_location
  • (string) --

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

copy(CopySource, ExtraArgs=None, Callback=None, SourceClient=None, Config=None)

Copy an object from one S3 location to this object.

This is a managed transfer which will perform a multipart copy in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'mybucket',
    'Key': 'mykey'
}
bucket = s3.Bucket('otherbucket')
obj = bucket.Object('otherkey')
obj.copy(copy_source)
Parameters
  • CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the copy.
  • SourceClient (botocore or boto3 Client) -- The client to be used for operation that may happen at the source object. For example, this client is used for the head_object that determines the size of the copy. If no client is provided, the current client is used as the client for the source object.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the copy.
copy_from(**kwargs)

Creates a copy of an object that is already stored in Amazon S3.

Note

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API .

All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication . Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately.

If the copy is successful, you receive a response with information about the copied object.

Note

If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.

The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing .

Warning

Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration .

Metadata

When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs .

To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide . For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3 .

x-amz-copy-source-if Headers

To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters:

  • x-amz-copy-source-if-match
  • x-amz-copy-source-if-none-match
  • x-amz-copy-source-if-unmodified-since
  • x-amz-copy-source-if-modified-since

If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:

  • x-amz-copy-source-if-match condition evaluates to true
  • x-amz-copy-source-if-unmodified-since condition evaluates to false

If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:

  • x-amz-copy-source-if-none-match condition evaluates to false
  • x-amz-copy-source-if-modified-since condition evaluates to true

Note

All headers with the x-amz- prefix, including x-amz-copy-source , must be signed.

Server-side encryption

When you perform a CopyObject operation, you can optionally use the appropriate encryption-related headers to encrypt the object using server-side encryption with Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS) or a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption .

If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Checksums

When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header.

Storage Class Options

You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource.

If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.

If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.

If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject .

The following operations are related to CopyObject :

For more information, see Copying Objects .

delete(**kwargs)

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker , to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.

For more information about MFA Delete, see Using MFA Delete . To see sample requests that use versioning, see Sample Request .

You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle ) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject , s3:DeleteObjectVersion , and s3:PutLifeCycleConfiguration actions.

The following action is related to DeleteObject :

Parameters
  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • VersionId (string) -- VersionId used to reference a specific version of the object.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

download_file(Filename, ExtraArgs=None, Callback=None, Config=None)

Download an S3 object to a file.

Usage:

import boto3
s3 = boto3.resource('s3')
s3.Object('mybucket', 'hello.txt').download_file('/tmp/hello.txt')

Similar behavior as S3Transfer's download_file() method, except that parameters are capitalized. Detailed examples can be found at S3Transfer's Usage.

Parameters
  • Filename (str) -- The path to the file to download to.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the download.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the transfer.
download_fileobj(Fileobj, ExtraArgs=None, Callback=None, Config=None)

Download this object from S3 to a file-like object.

The file-like object must be in binary mode.

This is a managed transfer which will perform a multipart download in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
obj = bucket.Object('mykey')

with open('filename', 'wb') as data:
    obj.download_fileobj(data)
Parameters
  • Fileobj (a file-like object) -- A file-like object to download into. At a minimum, it must implement the write method and must accept bytes.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed download arguments see boto3.s3.transfer.S3Transfer.ALLOWED_DOWNLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the download.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the download.
get(**kwargs)

Retrieves objects from Amazon S3. To use GET , you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg , you can name it photos/2006/February/sample.jpg .

To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg , specify the resource as /photos/2006/February/sample.jpg . For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket , specify the resource as /examplebucket/photos/2006/February/sample.jpg . For more information about request types, see HTTP Host Header Bucket Specification .

For more information about returning the ACL of an object, see GetObjectAcl .

If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject . Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects .

Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning

By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.

Note

  • If you supply a versionId , you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission.
  • If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

For more information about versioning, see PutBucketVersioning .

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type , Content-Language , Expires , Cache-Control , Content-Disposition , and Content-Encoding . To override these header values in the GET response, you use the following request parameters.

Note

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

  • response-content-type
  • response-content-language
  • response-expires
  • response-cache-control
  • response-content-disposition
  • response-content-encoding
Additional Considerations about Request Headers

If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true , and; If-Unmodified-Since condition evaluates to false ; then, S3 returns 200 OK and the data requested.

If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:If-None-Match condition evaluates to false , and; If-Modified-Since condition evaluates to true ; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232 .

get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
initiate_multipart_upload(**kwargs)

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart ). You also include this upload ID in the final request to either complete or abort the multipart upload request.

For more information about multipart uploads, see Multipart Upload Overview .

If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy .

For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions .

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4) .

Note

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.

You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use Amazon Web Services KMS keys or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload .

To perform a multipart upload with encryption using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions in the Amazon S3 User Guide .

If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.

For more information, see Protecting Data Using Server-Side Encryption .

Access Permissions

When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

  • Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL .
  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview .

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Server-Side- Encryption-Specific Request Headers

You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use Amazon Web Services managed encryption keys or provide your own encryption key.

  • Use encryption keys managed by Amazon S3 or customer managed key stored in Amazon Web Services Key Management Service (Amazon Web Services KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.
    • x-amz-server-side-encryption
    • x-amz-server-side-encryption-aws-kms-key-id
    • x-amz-server-side-encryption-context

Note

If you specify x-amz-server-side-encryption:aws:kms , but don't provide x-amz-server-side-encryption-aws-kms-key-id , Amazon S3 uses the Amazon Web Services managed key in Amazon Web Services KMS to protect the data.

Warning

All GET and PUT requests for an object protected by Amazon Web Services KMS fail if you don't make them with SSL or by using SigV4.

For more information about server-side encryption with KMS key (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

  • Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.
    • x-amz-server-side-encryption-customer-algorithm
    • x-amz-server-side-encryption-customer-key
    • x-amz-server-side-encryption-customer-key-MD5

For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

Access-Control-List (ACL)-Specific Request Headers

You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs . With this operation, you can grant access permissions using one of the following two methods:

  • Specify a canned ACL (x-amz-acl ) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .
  • Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:
    • x-amz-grant-read
    • x-amz-grant-write
    • x-amz-grant-read-acp
    • x-amz-grant-write-acp
    • x-amz-grant-full-control

You specify each grantee as a type=value pair, where the type is one of the following:

  • id – if the value specified is the canonical user ID of an Amazon Web Services account
  • uri – if you are granting permissions to a predefined group
  • emailAddress – if the value specified is the email address of an Amazon Web Services account

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"

The following operations are related to CreateMultipartUpload :

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with an object action doesn’t affect bucket-level settings for S3 Bucket Key.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • Tagging (string) -- The tag-set for the object. The tag-set must be encoded as URL Query parameters.

Return type

s3.MultipartUpload

Returns

MultipartUpload resource

load()

Calls S3.Client.head_object() to update the attributes of the Object resource. Note that the load and reload methods are the same method and can be used interchangeably.

Request Syntax

object.load()
Returns
None
put(**kwargs)

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.

To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

Note

  • To successfully complete the PutObject request, you must have the s3:PutObject in your IAM permissions.
  • To successfully change the objects acl of your PutObject request, you must have the s3:PutObjectAcl in your IAM permissions.
  • The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide .

Server-side Encryption

You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption .

If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported .

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Storage Class Options

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.

For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

  • ContentMD5 (string) -- The base64-encoded 128-bit MD5 digest of the message (without the headers) according to RFC 1864. This header can be used as a message integrity check to verify that the data is the same data that was originally sent. Although it is optional, we recommend using the Content-MD5 mechanism as an end-to-end integrity check. For more information about REST request authentication, see REST Authentication .
  • ContentType (string) -- A standard MIME type describing the format of the contents. For more information, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.17 .
  • ChecksumAlgorithm (string) --

    Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 Bad Request . For more information, see Checking object integrity in the Amazon S3 User Guide .

    If you provide an individual checksum, Amazon S3 ignores any provided ChecksumAlgorithm parameter.

  • ChecksumCRC32 (string) -- This header can be used as a data integrity check to verify that the data received is the same data that was originally sent. This header specifies the base64-encoded, 32-bit CRC32 checksum of the object. For more information, see Checking object integrity in the Amazon S3 User Guide .

    Allows grantee to write the ACL for the applicable object.

    This action is not supported by Amazon S3 on Outposts.

  • Metadata (dict) --

    A map of metadata to store with the object in S3.

    • (string) --
      • (string) --
  • ServerSideEncryption (string) -- The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
  • StorageClass (string) -- By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .
  • WebsiteRedirectLocation (string) --

    If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata .

    In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:

    x-amz-website-redirect-location: /anotherPage.html

    In the following example, the request header sets the object redirect to another website:

    x-amz-website-redirect-location: http://www.example.com/

    For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects .

  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • SSEKMSKeyId (string) -- If x-amz-server-side-encryption is present and has the value of aws:kms , this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetrical customer managed key that was used for the object. If you specify x-amz-server-side-encryption:aws:kms , but do not provide``x-amz-server-side-encryption-aws-kms-key-id`` , Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.
  • SSEKMSEncryptionContext (string) -- Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
  • BucketKeyEnabled (boolean) --

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • Tagging (string) -- The tag-set for the object. The tag-set must be encoded as URL Query parameters. (For example, "Key1=Value1")
  • ObjectLockMode (string) -- The Object Lock mode that you want to apply to this object.
  • ObjectLockRetainUntilDate (datetime) -- The date and time when you want this object's Object Lock to expire. Must be formatted as a timestamp parameter.
  • ObjectLockLegalHoldStatus (string) -- Specifies whether a legal hold will be applied to this object. For more information about S3 Object Lock, see Object Lock .
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

Request Syntax

object.reload()
Returns

restore_object(**kwargs)

Restores an archived copy of an object back into Amazon S3

This action is not supported by Amazon S3 on Outposts.

This action performs the following types of requests:

  • select - Perform a select query on an archived object
  • restore an archive - Restore an archived object

To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide .

Querying Archives with Select Requests

You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon S3 User Guide .

When making a select request, do the following:

  • Define an output location for the select query's output. This must be an Amazon S3 bucket in the same Amazon Web Services Region as the bucket that contains the archive object that is being queried. The Amazon Web Services account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon S3 User Guide . For more information about the S3 structure in the request body, see the following:
  • Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.
    • The following expression returns all records from the specified object. SELECT * FROM Object
    • Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers. SELECT s._1, s._2 FROM Object s WHERE s._3 > 100
    • If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE , you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE , the first row is skipped for the query.) You cannot mix ordinal positions with header column names. SELECT s.Id, s.FirstName, s.SSN FROM S3Object s

For more information about using SQL with S3 Glacier Select restore, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide .

When making a select request, you can also do the following:

  • To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.
  • Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.

The following are additional important facts about the select feature:

  • The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.
  • You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.
  • Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409 .
Restoring objects

Objects that you archive to the S3 Glacier or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers are not accessible in real time. For objects in Archive Access or Deep Archive Access tiers you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier. For objects in S3 Glacier or S3 Glacier Deep Archive storage classes you must first initiate a restore request, and then wait until a temporary copy of the object is available. To access an archived object, you must restore the object for the duration (number of days) that you specify.

To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.

When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:

  • Expedited - Expedited retrievals allow you to quickly access your data stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
  • Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
  • Bulk - Bulk retrievals are the lowest-cost retrieval option in S3 Glacier, enabling you to retrieve large amounts, even petabytes, of data inexpensively. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Bulk retrievals are free for objects stored in S3 Intelligent-Tiering.

For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide .

You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide .

To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide .

After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.

If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide .

Responses

A successful action returns either the 200 OK or 202 Accepted status code.

  • If the object is not previously restored, then Amazon S3 returns 202 Accepted in the response.
  • If the object is previously restored, Amazon S3 returns 200 OK in the response.
Special Errors
    • Code: RestoreAlreadyInProgress
    • Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)
    • HTTP Status Code: 409 Conflict
    • SOAP Fault Code Prefix: Client
    • Code: GlacierExpeditedRetrievalNotAvailable
    • Cause: expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)
    • HTTP Status Code: 503
    • SOAP Fault Code Prefix: N/A

upload_file(Filename, ExtraArgs=None, Callback=None, Config=None)

Upload a file to an S3 object.

Usage:

import boto3
s3 = boto3.resource('s3')
s3.Object('mybucket', 'hello.txt').upload_file('/tmp/hello.txt')

Similar behavior as S3Transfer's upload_file() method, except that parameters are capitalized. Detailed examples can be found at S3Transfer's Usage.

Parameters

  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the transfer.
upload_fileobj(Fileobj, ExtraArgs=None, Callback=None, Config=None)

Upload a file-like object to this object.

The file-like object must be in binary mode.

This is a managed transfer which will perform a multipart upload in multiple threads if necessary.

Usage:

import boto3
s3 = boto3.resource('s3')
bucket = s3.Bucket('mybucket')
obj = bucket.Object('mykey')

with open('filename', 'rb') as data:
    obj.upload_fileobj(data)
Parameters
  • Fileobj (a file-like object) -- A file-like object to upload. At a minimum, it must implement the read method, and must return bytes.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation. For allowed upload arguments see boto3.s3.transfer.S3Transfer.ALLOWED_UPLOAD_ARGS.
  • Callback (function) -- A method which takes a number of bytes transferred to be periodically called during the upload.
  • Config (boto3.s3.transfer.TransferConfig) -- The transfer configuration to be used when performing the upload.

Parameters
  • IfMatch (string) -- Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.
  • IfModifiedSince (datetime) -- Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.
  • IfNoneMatch (string) -- Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.
  • IfUnmodifiedSince (datetime) -- Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.
  • Range (string) -- Because HeadObject returns only the metadata for an object, this parameter has no effect.
  • VersionId (string) -- VersionId used to reference a specific version of the object.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • PartNumber (integer) -- Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumMode (string) --

    To retrieve the checksum, this parameter must be enabled.

    In addition, if you enable ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

Returns

None

wait_until_not_exists(**kwargs)

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load()

Calls S3.Client.get_object_acl() to update the attributes of the ObjectAcl resource. Note that the load and reload methods are the same method and can be used interchangeably.

See also: AWS API Documentation

Request Syntax

object_acl.load()
Returns
None
put(**kwargs)

Uses the acl subresource to set the access control list (ACL) permissions for a new or existing object in an S3 bucket. You must have WRITE_ACP permission to set the ACL of an object. For more information, see What permissions can I grant? in the Amazon S3 User Guide .

This action is not supported by Amazon S3 on Outposts.

Depending on your application needs, you can choose to set the ACL on an object using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, you can continue to use that approach. For more information, see Access Control List (ACL) Overview in the Amazon S3 User Guide .

Warning

If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the AccessControlListNotSupported error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide .

Access Permissions

You can set access permissions using one of the following methods:

  • Specify a canned ACL with the x-amz-acl request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-ac l. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL .

  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use x-amz-acl header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . You specify each grantee as a type=value pair, where the type is one of the following:

    • id – if the value specified is the canonical user ID of an Amazon Web Services account
    • uri – if you are granting permissions to a predefined group
    • emailAddress – if the value specified is the email address of an Amazon Web Services account

    Note

    Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

    • US East (N. Virginia)
    • US West (N. California)
    • US West (Oregon)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Tokyo)
    • Europe (Ireland)
    • South America (São Paulo)

    For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants list objects permission to the two Amazon Web Services accounts identified by their email addresses.

x-amz-grant-read: emailAddress="xyz@amazon.com", emailAddress="abc@amazon.com"

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Grantee Values

You can specify the person (grantee) to whom you're assigning access rights (using request elements) in the following ways:

  • By the person's ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request.
  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>lt;/Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

Versioning

The ACL of an object is set at the object version level. By default, PUT sets the ACL of the current version of an object. To set the ACL of a different version, use the versionId subresource.

Sub-resources

Sub-resources are methods that create a new instance of a child resource. This resource's identifiers get passed along to the child. For more information about sub-resources refer to the Resources Introduction Guide.

Object()

Creates a Object resource.:

object = object_acl.Object()
Return type
S3.Object
Returns
A Object resource

ObjectSummary

class S3.ObjectSummary(bucket_name, key)

A resource representing an Amazon Simple Storage Service (S3) ObjectSummary:

import boto3

s3 = boto3.resource('s3')
object_summary = s3.ObjectSummary('bucket_name','key')
Parameters
  • bucket_name (string) -- The ObjectSummary's bucket_name identifier. This must be set.
  • key (string) -- The ObjectSummary's key identifier. This must be set.

These are the resource's available identifiers:

These are the resource's available attributes:

These are the resource's available actions:

These are the resource's available sub-resources:

These are the resource's available waiters:

Identifiers

Identifiers are properties of a resource that are set upon instantiation of the resource. For more information about identifiers refer to the Resources Introduction Guide.

bucket_name

(string) The ObjectSummary's bucket_name identifier. This must be set.

key

(string) The ObjectSummary's key identifier. This must be set.

Attributes

Attributes provide access to the properties of a resource. Attributes are lazy-loaded the first time one is accessed via the load() method. For more information about attributes refer to the Resources Introduction Guide.

checksum_algorithm
  • (list) --

    The algorithm that was used to create a checksum of the object.

    • (string) --
e_tag
  • (string) --

    The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Whether or not it is depends on how the object was created and how it is encrypted as described below:

    • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-S3 or plaintext, have ETags that are an MD5 digest of their object data.
    • Objects created by the PUT Object, POST Object, or Copy operation, or through the Amazon Web Services Management Console, and are encrypted by SSE-C or SSE-KMS, have ETags that are not an MD5 digest of their object data.
    • If an object is created by either the Multipart Upload or Part Copy operation, the ETag is not an MD5 digest, regardless of the method of encryption. If an object is larger than 16 MB, the Amazon Web Services Management Console will upload or copy that object as a Multipart Upload, and therefore the ETag will not be an MD5 digest.
last_modified
  • (datetime) --

    Creation date of the object.

owner
  • (dict) --

    The owner of the object

    • DisplayName (string) --

      Container for the display name of the owner.

    • ID (string) --

      Container for the ID of the owner.

size
  • (integer) --

    Size in bytes of the object

storage_class
  • (string) --

    The class of storage used to store the object.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

copy_from(**kwargs)

Creates a copy of an object that is already stored in Amazon S3.

Note

You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic action using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy (UploadPartCopy) API. For more information, see Copy Object Using the REST Multipart Upload API .

All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication . Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.

A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy action starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately.

If the copy is successful, you receive a response with information about the copied object.

Note

If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.

The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing .

Warning

Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration .

Metadata

When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs .

To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 User Guide . For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3 .

x-amz-copy-source-if Headers

To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters:

  • x-amz-copy-source-if-match
  • x-amz-copy-source-if-none-match
  • x-amz-copy-source-if-unmodified-since
  • x-amz-copy-source-if-modified-since

If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:

  • x-amz-copy-source-if-match condition evaluates to true
  • x-amz-copy-source-if-unmodified-since condition evaluates to false

If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:

  • x-amz-copy-source-if-none-match condition evaluates to false
  • x-amz-copy-source-if-modified-since condition evaluates to true

Note

All headers with the x-amz- prefix, including x-amz-copy-source , must be signed.

Server-side encryption

When you perform a CopyObject operation, you can optionally use the appropriate encryption-related headers to encrypt the object using server-side encryption with Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS) or a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. For more information about server-side encryption, see Using Server-Side Encryption .

If a target object uses SSE-KMS, you can enable an S3 Bucket Key for the object. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're copying objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format.

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Checksums

When copying an object, if it has a checksum, that checksum will be copied to the new object by default. When you copy the object over, you may optionally specify a different checksum algorithm to use with the x-amz-checksum-algorithm header.

Storage Class Options

You can use the CopyObject action to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource.

If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.

If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.

If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject .

The following operations are related to CopyObject :

For more information, see Copying Objects .

Parameters
  • ACL (string) --

    The canned ACL to apply to the object.

    This action is not supported by Amazon S3 on Outposts.

  • CacheControl (string) -- Specifies caching behavior along the request/reply chain.
  • ChecksumAlgorithm (string) -- Indicates the algorithm you want Amazon S3 to use to create the checksum for the object. For more information, see Checking object integrity in the Amazon S3 User Guide .
  • ContentDisposition (string) -- Specifies presentational information for the object.
  • ContentEncoding (string) -- Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

  • CopySource (str or dict) -- [REQUIRED] The name of the source bucket, key name of the source object, and optional version ID of the source object. You can either provide this value as a string or a dictionary. The string form is {bucket}/{key} or {bucket}/{key}?versionId={versionId} if you want to copy a specific version. You can also provide this value as a dictionary. The dictionary format is recommended over the string format because it is more explicit. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted. To specify an S3 access point, provide the access point ARN for the Bucket key in the copy source dictionary. If you want to provide the copy source for an S3 access point as a string instead of a dictionary, the ARN provided must be the full S3 access point object ARN (i.e. {accesspoint_arn}/object/{key})
  • CopySourceIfMatch (string) -- Copies the object if its entity tag (ETag) matches the specified tag.
  • CopySourceIfModifiedSince (datetime) -- Copies the object if it has been modified since the specified time.

delete(**kwargs)

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker , to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.

For more information about MFA Delete, see Using MFA Delete . To see sample requests that use versioning, see Sample Request .

You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle ) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject , s3:DeleteObjectVersion , and s3:PutLifeCycleConfiguration actions.

The following action is related to DeleteObject :

See also: AWS API Documentation

Request Syntax

response = object_summary.delete(
    MFA='string',
    VersionId='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string'
)
Parameters
  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • VersionId (string) -- VersionId used to reference a specific version of the object.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

    'RequestCharged': 'requester'
}

Response Structure

  • (dict) --

    • DeleteMarker (boolean) --

      Specifies whether the versioned object that was permanently deleted was (true) or was not (false) a delete marker.

    • VersionId (string) --

      Returns the version ID of the delete marker created as a result of the DELETE operation.

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

get(**kwargs)

Retrieves objects from Amazon S3. To use GET , you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg , you can name it photos/2006/February/sample.jpg .

To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg , specify the resource as /photos/2006/February/sample.jpg . For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket , specify the resource as /examplebucket/photos/2006/February/sample.jpg . For more information about request types, see HTTP Host Header Bucket Specification .

For more information about returning the ACL of an object, see GetObjectAcl .

If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject . Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects .

Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning

By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.

Note

  • If you supply a versionId , you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission.
  • If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

For more information about versioning, see PutBucketVersioning .

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type , Content-Language , Expires , Cache-Control , Content-Disposition , and Content-Encoding . To override these header values in the GET response, you use the following request parameters.

Note

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

  • response-content-type
  • response-content-language
  • response-expires
  • response-cache-control
  • response-content-disposition
  • response-content-encoding
Additional Considerations about Request Headers

If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true , and; If-Unmodified-Since condition evaluates to false ; then, S3 returns 200 OK and the data requested.

If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:If-None-Match condition evaluates to false , and; If-Modified-Since condition evaluates to true ; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232 .

initiate_multipart_upload(**kwargs)

This action initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart ). You also include this upload ID in the final request to either complete or abort the multipart upload request.

For more information about multipart uploads, see Multipart Upload Overview .

If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort action and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy .

For information about the permissions required to use the multipart upload API, see Multipart Upload and Permissions .

For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (Amazon Web Services Signature Version 4) .

Note

After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.

You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use Amazon Web Services KMS keys or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload .

To perform a multipart upload with encryption using an Amazon Web Services KMS key, the requester must have permission to the kms:Decrypt and kms:GenerateDataKey* actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information, see Multipart upload API and permissions in the Amazon S3 User Guide .

If your Identity and Access Management (IAM) user or role is in the same Amazon Web Services account as the KMS key, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.

For more information, see Protecting Data Using Server-Side Encryption .

Access Permissions

When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:

  • Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL .
  • Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview .

You can use either a canned ACL or specify access permissions explicitly. You cannot do both.

Server-Side- Encryption-Specific Request Headers

You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use Amazon Web Services managed encryption keys or provide your own encryption key.

  • Use encryption keys managed by Amazon S3 or customer managed key stored in Amazon Web Services Key Management Service (Amazon Web Services KMS) – If you want Amazon Web Services to manage the keys used to encrypt data, specify the following headers in the request.
    • x-amz-server-side-encryption
    • x-amz-server-side-encryption-aws-kms-key-id
    • x-amz-server-side-encryption-context

Note

If you specify x-amz-server-side-encryption:aws:kms , but don't provide x-amz-server-side-encryption-aws-kms-key-id , Amazon S3 uses the Amazon Web Services managed key in Amazon Web Services KMS to protect the data.

Warning

All GET and PUT requests for an object protected by Amazon Web Services KMS fail if you don't make them with SSL or by using SigV4.

For more information about server-side encryption with KMS key (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

  • Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.
    • x-amz-server-side-encryption-customer-algorithm
    • x-amz-server-side-encryption-customer-key
    • x-amz-server-side-encryption-customer-key-MD5

For more information about server-side encryption with KMS keys (SSE-KMS), see Protecting Data Using Server-Side Encryption with KMS keys .

Access-Control-List (ACL)-Specific Request Headers

You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs . With this operation, you can grant access permissions using one of the following two methods:

  • Specify a canned ACL (x-amz-acl ) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .
  • Specify access permissions explicitly — To explicitly grant access permissions to specific Amazon Web Services accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:
    • x-amz-grant-read
    • x-amz-grant-write
    • x-amz-grant-read-acp
    • x-amz-grant-write-acp
    • x-amz-grant-full-control

You specify each grantee as a type=value pair, where the type is one of the following:

  • id – if the value specified is the canonical user ID of an Amazon Web Services account
  • uri – if you are granting permissions to a predefined group
  • emailAddress – if the value specified is the email address of an Amazon Web Services account

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)
  • US West (N. California)
  • US West (Oregon)
  • Asia Pacific (Singapore)
  • Asia Pacific (Sydney)
  • Asia Pacific (Tokyo)
  • Europe (Ireland)
  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

For example, the following x-amz-grant-read header grants the Amazon Web Services accounts identified by account IDs permissions to read object data and its metadata:

x-amz-grant-read: id="11112222333", id="444455556666"

Return type

s3.MultipartUpload

Returns

MultipartUpload resource

load(*args, **kwargs)

Calls s3.Client.head_object to update the attributes of the ObjectSummary resource.

put(**kwargs)

Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.

Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.

Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.

To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.

Note

  • To successfully complete the PutObject request, you must have the s3:PutObject in your IAM permissions.
  • To successfully change the objects acl of your PutObject request, you must have the s3:PutObjectAcl in your IAM permissions.
  • The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon S3 User Guide .

Server-side Encryption

You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use Amazon Web Services managed encryption keys (SSE-S3 or SSE-KMS). For more information, see Using Server-Side Encryption .

If you request server-side encryption using Amazon Web Services Key Management Service (SSE-KMS), you can enable an S3 Bucket Key at the object-level. For more information, see Amazon S3 Bucket Keys in the Amazon S3 User Guide .

Access Control List (ACL)-Specific Request Headers

You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual Amazon Web Services accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .

If the bucket that you're uploading objects to uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. Buckets that use this setting only accept PUT requests that don't specify an ACL or PUT requests that specify bucket owner full control ACLs, such as the bucket-owner-full-control canned ACL or an equivalent form of this ACL expressed in the XML format. PUT requests that contain other ACLs (for example, custom grants to certain Amazon Web Services accounts) fail and return a 400 error with the error code AccessControlListNotSupported .

For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide .

Note

If your bucket uses the bucket owner enforced setting for Object Ownership, all objects written to the bucket by any account will be owned by the bucket owner.

Storage Class Options

By default, Amazon S3 uses the STANDARD Storage Class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different Storage Class. Amazon S3 on Outposts only uses the OUTPOSTS Storage Class. For more information, see Storage Classes in the Amazon S3 User Guide .

Versioning

If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.

For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

If you specify x-amz-server-side-encryption:aws:kms , but do not provide``x-amz-server-side-encryption-aws-kms-key-id`` , Amazon S3 uses the Amazon Web Services managed key to protect the data. If the KMS key does not exist in the same account issuing the command, you must use the full ARN and not just the ID.
  • SSEKMSEncryptionContext (string) -- Specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.
  • BucketKeyEnabled (boolean) --

    Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using AWS KMS (SSE-KMS). Setting this header to true causes Amazon S3 to use an S3 Bucket Key for object encryption with SSE-KMS.

    Specifying this header with a PUT action doesn’t affect bucket-level settings for S3 Bucket Key.

  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .

      If server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.

    • SSECustomerKeyMD5 (string) --

      If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.

    • SSEKMSKeyId (string) --

      If x-amz-server-side-encryption is present and has the value of aws:kms , this header specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetric customer managed key that was used for the object.

    • SSEKMSEncryptionContext (string) --

      If present, specifies the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.

    • BucketKeyEnabled (boolean) --

      Indicates whether the uploaded object uses an S3 Bucket Key for server-side encryption with Amazon Web Services KMS (SSE-KMS).

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

restore_object(**kwargs)

Restores an archived copy of an object back into Amazon S3

This action is not supported by Amazon S3 on Outposts.

This action performs the following types of requests:

  • select - Perform a select query on an archived object
  • restore an archive - Restore an archived object

To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon S3 User Guide .

Querying Archives with Select Requests

You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon S3 User Guide .

When making a select request, do the following:

  • Define an output location for the select query's output. This must be an Amazon S3 bucket in the same Amazon Web Services Region as the bucket that contains the archive object that is being queried. The Amazon Web Services account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon S3 User Guide . For more information about the S3 structure in the request body, see the following:
  • Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.
    • The following expression returns all records from the specified object. SELECT * FROM Object
    • Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers. SELECT s._1, s._2 FROM Object s WHERE s._3 > 100
    • If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE , you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE , the first row is skipped for the query.) You cannot mix ordinal positions with header column names. SELECT s.Id, s.FirstName, s.SSN FROM S3Object s

For more information about using SQL with S3 Glacier Select restore, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon S3 User Guide .

When making a select request, you can also do the following:

  • To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.
  • Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.

The following are additional important facts about the select feature:

  • The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.
  • You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.
  • Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409 .
Restoring objects

Objects that you archive to the S3 Glacier or S3 Glacier Deep Archive storage class, and S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers are not accessible in real time. For objects in Archive Access or Deep Archive Access tiers you must first initiate a restore request, and then wait until the object is moved into the Frequent Access tier. For objects in S3 Glacier or S3 Glacier Deep Archive storage classes you must first initiate a restore request, and then wait until a temporary copy of the object is available. To access an archived object, you must restore the object for the duration (number of days) that you specify.

To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.

When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:

  • Expedited - Expedited retrievals allow you to quickly access your data stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals is typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier.
  • Standard - Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for retrieval requests that do not specify the retrieval option. Standard retrievals typically finish within 3–5 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 12 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Standard retrievals are free for objects stored in S3 Intelligent-Tiering.
  • Bulk - Bulk retrievals are the lowest-cost retrieval option in S3 Glacier, enabling you to retrieve large amounts, even petabytes, of data inexpensively. Bulk retrievals typically finish within 5–12 hours for objects stored in the S3 Glacier storage class or S3 Intelligent-Tiering Archive tier. They typically finish within 48 hours for objects stored in the S3 Glacier Deep Archive storage class or S3 Intelligent-Tiering Deep Archive tier. Bulk retrievals are free for objects stored in S3 Intelligent-Tiering.

For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon S3 User Guide .

You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. For more information, see Upgrading the speed of an in-progress restore in the Amazon S3 User Guide .

To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon S3 User Guide .

After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.

If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon S3 User Guide .

Responses

A successful action returns either the 200 OK or 202 Accepted status code.

  • If the object is not previously restored, then Amazon S3 returns 202 Accepted in the response.
  • If the object is previously restored, Amazon S3 returns 200 OK in the response.
Special Errors
    • Code: RestoreAlreadyInProgress
    • Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)
    • HTTP Status Code: 409 Conflict
    • SOAP Fault Code Prefix: Client
    • Code: GlacierExpeditedRetrievalNotAvailable
    • Cause: expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)
    • HTTP Status Code: 503
    • SOAP Fault Code Prefix: N/A

The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • PartNumber (integer) -- Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

delete(**kwargs)

Removes the null version (if there is one) of an object and inserts a delete marker, which becomes the latest version of the object. If there isn't a null version, Amazon S3 does not remove any objects but will still respond that the command was successful.

To remove a specific version, you must be the bucket owner and you must use the version Id subresource. Using this subresource permanently deletes the version. If the object deleted is a delete marker, Amazon S3 sets the response header, x-amz-delete-marker , to true.

If the object you want to delete is in a bucket where the bucket versioning configuration is MFA Delete enabled, you must include the x-amz-mfa request header in the DELETE versionId request. Requests that include x-amz-mfa must use HTTPS.

For more information about MFA Delete, see Using MFA Delete . To see sample requests that use versioning, see Sample Request .

You can delete objects by explicitly calling DELETE Object or configure its lifecycle (PutBucketLifecycle ) to enable Amazon S3 to remove them for you. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them the s3:DeleteObject , s3:DeleteObjectVersion , and s3:PutLifeCycleConfiguration actions.

The following action is related to DeleteObject :

See also: AWS API Documentation

Request Syntax

response = object_version.delete(
    MFA='string',
    RequestPayer='requester',
    BypassGovernanceRetention=True|False,
    ExpectedBucketOwner='string'
)
Parameters
  • MFA (string) -- The concatenation of the authentication device's serial number, a space, and the value that is displayed on your authentication device. Required to permanently delete a versioned object if versioning is configured with MFA delete enabled.
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • BypassGovernanceRetention (boolean) -- Indicates whether S3 Object Lock should bypass Governance-mode restrictions to process this operation. To use this header, you must have the s3:BypassGovernanceRetention permission.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
Return type

dict

Returns

Response Syntax

{
    'DeleteMarker': True|False,
    'VersionId': 'string',
    'RequestCharged': 'requester'
}

Response Structure

  • (dict) --

    • DeleteMarker (boolean) --

      Specifies whether the versioned object that was permanently deleted was (true) or was not (false) a delete marker.

    • VersionId (string) --

      Returns the version ID of the delete marker created as a result of the DELETE operation.

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

get(**kwargs)

Retrieves objects from Amazon S3. To use GET , you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.

An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg , you can name it photos/2006/February/sample.jpg .

To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg , specify the resource as /photos/2006/February/sample.jpg . For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket , specify the resource as /examplebucket/photos/2006/February/sample.jpg . For more information about request types, see HTTP Host Header Bucket Specification .

For more information about returning the ACL of an object, see GetObjectAcl .

If the object you are retrieving is stored in the S3 Glacier or S3 Glacier Deep Archive storage class, or S3 Intelligent-Tiering Archive or S3 Intelligent-Tiering Deep Archive tiers, before you can retrieve the object you must first restore a copy using RestoreObject . Otherwise, this action returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects .

Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Assuming you have the relevant permission to read object tags, the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning

By default, the GET action returns the current version of an object. To return a different version, use the versionId subresource.

Note

  • If you supply a versionId , you need the s3:GetObjectVersion permission to access a specific version of an object. If you request a specific version, you do not need to have the s3:GetObject permission.
  • If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.

For more information about versioning, see PutBucketVersioning .

Overriding Response Header Values

There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.

You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type , Content-Language , Expires , Cache-Control , Content-Disposition , and Content-Encoding . To override these header values in the GET response, you use the following request parameters.

Note

You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.

  • response-content-type
  • response-content-language
  • response-expires
  • response-cache-control
  • response-content-disposition
  • response-content-encoding
Additional Considerations about Request Headers

If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true , and; If-Unmodified-Since condition evaluates to false ; then, S3 returns 200 OK and the data requested.

If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:If-None-Match condition evaluates to false , and; If-Modified-Since condition evaluates to true ; then, S3 returns 304 Not Modified response code.

For more information about conditional requests, see RFC 7232 .

      Amazon S3 can return this if your request involves a bucket that is either a source or destination in a replication rule.

    • PartsCount (integer) --

      The count of parts this object has. This value is only returned if you specify partNumber in your request and the object was uploaded as a multipart upload.

    • TagCount (integer) --

      The number of tags, if any, on the object.

    • ObjectLockMode (string) --

      The Object Lock mode currently in place for this object.

    • ObjectLockRetainUntilDate (datetime) --

      The date and time when this object's Object Lock will expire.

    • ObjectLockLegalHoldStatus (string) --

      Indicates whether this object has an active legal hold. This field is only returned if you have permission to view an object's legal hold status.

get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
head(**kwargs)

The HEAD action retrieves metadata from an object without returning the object itself. This action is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.

A HEAD request has the same options as a GET action on an object. The response is identical to the GET response except that there is no response body. Because of this, if the HEAD request generates an error, it returns a generic 404 Not Found or 403 Forbidden code. It is not possible to retrieve the exact exception beyond these error codes.

If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:

  • x-amz-server-side-encryption-customer-algorithm
  • x-amz-server-side-encryption-customer-key
  • x-amz-server-side-encryption-customer-key-MD5

For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .

Note

  • Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with KMS keys (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
  • The last modified property in this case is the creation date of the object.

Request headers are limited to 8 KB in size. For more information, see Common Request Headers .

Consider the following when using request headers:

  • Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:
    • If-Match condition evaluates to true , and;
    • If-Unmodified-Since condition evaluates to false ;

Then Amazon S3 returns 200 OK and the data requested.

  • Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:
    • If-None-Match condition evaluates to false , and;
    • If-Modified-Since condition evaluates to true ;

Then Amazon S3 returns the 304 Not Modified response code.

For more information about conditional requests, see RFC 7232 .

Permissions

You need the relevant read object (or version) permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.

  • If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error.
  • If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 ("access denied") error.

    SSECustomerKey='string',
    RequestPayer='requester',
    PartNumber=123,
    ExpectedBucketOwner='string',
    ChecksumMode='ENABLED'
)
Parameters
  • IfMatch (string) -- Return the object only if its entity tag (ETag) is the same as the one specified; otherwise, return a 412 (precondition failed) error.
  • IfModifiedSince (datetime) -- Return the object only if it has been modified since the specified time; otherwise, return a 304 (not modified) error.
  • IfNoneMatch (string) -- Return the object only if its entity tag (ETag) is different from the one specified; otherwise, return a 304 (not modified) error.
  • IfUnmodifiedSince (datetime) -- Return the object only if it has not been modified since the specified time; otherwise, return a 412 (precondition failed) error.
  • Range (string) -- Because HeadObject returns only the metadata for an object, this parameter has no effect.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (for example, AES256).
  • SSECustomerKey (string) -- Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
  • SSECustomerKeyMD5 (string) --

    Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

    Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required
  • RequestPayer (string) -- Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
  • PartNumber (integer) -- Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.
  • ExpectedBucketOwner (string) -- The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).
  • ChecksumMode (string) --

    To retrieve the checksum, this parameter must be enabled.

    In addition, if you enable ChecksumMode and the object is encrypted with Amazon Web Services Key Management Service (Amazon Web Services KMS), you must have permission to use the kms:Decrypt action for the request to succeed.

Response Structure

  • (dict) --

    • DeleteMarker (boolean) --

      Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.

    • AcceptRanges (string) --

      Indicates that a range of bytes was specified.

    • Expiration (string) --

      If the object expiration is configured (see PUT Bucket lifecycle), the response includes this header. It includes the expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL-encoded.

    • Restore (string) --

      If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.

      If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:

      x-amz-restore: ongoing-request="false", expiry-date="Fri, 21 Dec 2012 00:00:00 GMT"

      If the object restoration is in progress, the header returns the value ongoing-request="true" .

      For more information about archiving objects, see Transitioning Objects: General Considerations .

    • ArchiveStatus (string) --

      The archive state of the head object.

    • LastModified (datetime) --

    • ChecksumSHA1 (string) --

      The base64-encoded, 160-bit SHA-1 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide .

    • ChecksumSHA256 (string) --

      The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide .

    • ETag (string) --

      An entity tag (ETag) is an opaque identifier assigned by a web server to a specific version of a resource found at a URL.

    • MissingMeta (integer) --

      This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.

    • VersionId (string) --

      Version of the object.

    • CacheControl (string) --

      Specifies caching behavior along the request/reply chain.

    • ContentDisposition (string) --

      Specifies presentational information for the object.

    • ContentEncoding (string) --

      Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

    • ContentLanguage (string) --

      The language the content is in.

    • ContentType (string) --

      A standard MIME type describing the format of the object data.

    • Expires (datetime) --

      The date and time at which the object is no longer cacheable.

    • WebsiteRedirectLocation (string) --

      If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.

    • ServerSideEncryption (string) --

      If the object is stored using server-side encryption either with an Amazon Web Services KMS key or an Amazon S3-managed encryption key, the response includes this header with the value of the server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).

      If server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.

    • SSECustomerKeyMD5 (string) --

      If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.

    • SSEKMSKeyId (string) --

      If present, specifies the ID of the Amazon Web Services Key Management Service (Amazon Web Services KMS) symmetric customer managed key that was used for the object.

    • BucketKeyEnabled (boolean) --

      Indicates whether the object uses an S3 Bucket Key for server-side encryption with Amazon Web Services KMS (SSE-KMS).

    • StorageClass (string) --

      Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.

      For more information, see Storage Classes .

    • RequestCharged (string) --

      If present, indicates that the requester was successfully charged for the request.

    • ReplicationStatus (string) --

      Amazon S3 can return this header if your request involves a bucket that is either a source or a destination in a replication rule.

      In replication, you have a source bucket on which you configure replication and destination bucket or buckets where Amazon S3 stores object replicas. When you request an object (GetObject ) or object metadata (HeadObject ) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:

      • If requesting an object from the source bucket , Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs . Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf , are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
      • If requesting an object from a destination bucket , Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created and there is no replica modification replication in progress.
      • When replicating objects to multiple destination buckets , the x-amz-replication-status header acts differently. The header of the source object will only return a value of COMPLETED when replication is successful to all destinations. The header will remain at value PENDING until replication has completed for all destinations. If one or more destinations fails replication the header will return FAILED.

      For more information, see Replication .

    • PartsCount (integer) --

      The count of parts this object has. This value is only returned if you specify partNumber in your request and the object was uploaded as a multipart upload.

    • ObjectLockMode (string) --

      The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock .

    • ObjectLockRetainUntilDate (datetime) --

      The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.

    • ObjectLockLegalHoldStatus (string) --

      Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock .

Examples

List objects in an Amazon S3 bucket

The following example shows how to use an Amazon S3 bucket resource to list the objects in the bucket.

import boto3

s3 = boto3.resource('s3')
bucket = s3.Bucket('my-bucket')
for obj in bucket.objects.all():
    print(obj.key)

List top-level common prefixes in Amazon S3 bucket

This example shows how to list all of the top-level common prefixes in an Amazon S3 bucket:

import boto3

client = boto3.client('s3')
paginator = client.get_paginator('list_objects')
result = paginator.paginate(Bucket='my-bucket', Delimiter='/')
for prefix in result.search('CommonPrefixes'):
    print(prefix.get('Prefix'))

Restore Glacier objects in an Amazon S3 bucket

The following example shows how to initiate restoration of glacier objects in an Amazon S3 bucket, determine if a restoration is on-going, and determine if a restoration is finished.

import boto3

s3 = boto3.resource('s3')
bucket = s3.Bucket('glacier-bucket')
for obj_sum in bucket.objects.all():
    obj = s3.Object(obj_sum.bucket_name, obj_sum.key)
    if obj.storage_class == 'GLACIER':
        # Try to restore the object if the storage class is glacier and
        # the object does not have a completed or ongoing restoration
        # request.
        if obj.restore is None:
            print('Submitting restoration request: %s' % obj.key)
            obj.restore_object(RestoreRequest={'Days': 1})
        # Print out objects whose restoration is on-going
        elif 'ongoing-request="true"' in obj.restore:
            print('Restoration in-progress: %s' % obj.key)
        # Print out objects whose restoration is complete
        elif 'ongoing-request="false"' in obj.restore:
            print('Restoration complete: %s' % obj.key)

Uploading/downloading files using SSE KMS

This example shows how to use SSE-KMS to upload objects using server side encryption with a key managed by KMS.

We can either use the default KMS master key, or create a custom key in AWS and use it to encrypt the object by passing in its key id.

With KMS, nothing else needs to be provided for getting the object; S3 already knows how to decrypt the object.

import boto3
import os

BUCKET = 'your-bucket-name'
s3 = boto3.client('s3')
keyid = '<the key id>'

print("Uploading S3 object with SSE-KMS")
s3.put_object(Bucket=BUCKET,
              Key='encrypt-key',
              Body=b'foobar',
              ServerSideEncryption='aws:kms',
              # Optional: SSEKMSKeyId
              SSEKMSKeyId=keyid)
print("Done")

# Getting the object:
print("Getting S3 object...")
response = s3.get_object(Bucket=BUCKET,
                         Key='encrypt-key')
print("Done, response body:")
print(response['Body'].read())

Uploading/downloading files using SSE Customer Keys

This example shows how to use SSE-C to upload objects using server side encryption with a customer provided key.

First, we'll need a 32 byte key. For this example, we'll randomly generate a key but you can use any 32 byte key you want. Remember, you must the same key to download the object. If you lose the encryption key, you lose the object.

Also note how we don't have to provide the SSECustomerKeyMD5. Boto3 will automatically compute this value for us.

import boto3
import os

BUCKET = 'your-bucket-name'
KEY = os.urandom(32)
s3 = boto3.client('s3')

print("Uploading S3 object with SSE-C")
s3.put_object(Bucket=BUCKET,
              Key='encrypt-key',
              Body=b'foobar',
              SSECustomerKey=KEY,
              SSECustomerAlgorithm='AES256')
print("Done")

# Getting the object:
print("Getting S3 object...")
# Note how we're using the same ``KEY`` we
# created earlier.
response = s3.get_object(Bucket=BUCKET,
                         Key='encrypt-key',
                         SSECustomerKey=KEY,
                         SSECustomerAlgorithm='AES256')
print("Done, response body:")
print(response['Body'].read())

Downloading a specific version of an S3 object

This example shows how to download a specific version of an S3 object.

import boto3
s3 = boto3.client('s3')

s3.download_file(
    "bucket-name", "key-name", "tmp.txt",
    ExtraArgs={"VersionId": "my-version-id"}
)

Filter objects by last modified time using JMESPath

This example shows how to filter objects by last modified time using JMESPath.

import boto3
s3 = boto3.client("s3")

s3_paginator = s3.get_paginator('list_objects_v2')
s3_iterator = s3_paginator.paginate(Bucket='your-bucket-name')

filtered_iterator = s3_iterator.search(
    "Contents[?to_string(LastModified)>='\"2022-01-05 08:05:37+00:00\"'].Key"
)

for key_data in filtered_iterator:
    print(key_data)
