upload_fileobj

upload_fileobj(Fileobj, Key, ExtraArgs=None, Callback=None, Config=None)

Upload a file-like object to this bucket.

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')

with open('filename', 'rb') as data:
    bucket.upload_fileobj(data, '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.
• 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.
