upload_fileobj

S3.Object.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.
