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)

Aborts a multipart upload.

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

Request Syntax

response = client.abort_multipart_upload(
    Bucket='string',
    Key='string',
    UploadId='string',
    RequestPayer='requester'

Parameters
  • Bucket (string) -- [REQUIRED]
  • Key (string) -- [REQUIRED]
  • UploadId (string) -- [REQUIRED]
  • RequestPayer (string) -- Confirms that the requester knows that she or he will be charged for the request. Bucket owners need not specify this parameter in their requests.

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").

    '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.

create_multipart_upload(**kwargs)

Initiates a multipart upload and returns an upload ID.

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.

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

Download an S3 object to a file.

Usage:

import boto3
s3 = boto3.resource('s3')
s3.meta.client.download_file('mybucket', '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.

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
  • 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.
  • Bucket (str) -- The name of the bucket to download from.
  • Key (str) -- The name of the key to download from.
  • ExtraArgs (dict) -- Extra arguments that may be passed to the client operation.
  • Callback (method) -- 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)

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:

          • NoncurrentDays (integer) -- Specifies the number of days an object is noncurrent before Amazon S3 can perform the associated action. For information about the noncurrent days calculations, see How Amazon S3 Calculates When an Object Became Noncurrent in the Amazon Simple Storage Service Developer Guide.
          • StorageClass (string) -- The class of storage used to store the object.
        • NoncurrentVersionExpiration (dict) -- Specifies when noncurrent object versions expire. Upon expiration, Amazon S3 permanently deletes the noncurrent object versions. You set this lifecycle configuration action on a bucket that has versioning enabled (or suspended) to request that Amazon S3 delete noncurrent object versions at a specific period in the object's lifetime.
          • NoncurrentDays (integer) -- Specifies the number of days an object is noncurrent before Amazon S3 can perform the associated action. For information about the noncurrent days calculations, see How Amazon S3 Calculates When an Object Became Noncurrent in the Amazon Simple Storage Service Developer Guide.
        • AbortIncompleteMultipartUpload (dict) -- Specifies the days since the initiation of an Incomplete Multipart Upload that Lifecycle will wait before permanently removing all parts of the upload.

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.

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.
  • Callback (method) -- 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: 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.

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 the encryption key was transmitted without error. Please note that this parameter is automatically populated if it is not provided.

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.
  • CopySourceIfMatch (string) -- Copies the object if its entity tag (ETag) matches the specified tag.

  • 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 ten bytes of the source. You can copy a range only if the source object is greater than 5 GB.
  • Key (string) -- [REQUIRED]
  • PartNumber (integer) -- [REQUIRED] Part number of part being copied. This is a positive integer between 1 and 10,000.

Including this parameter is not required
  • CopySourceSSECustomerAlgorithm (string) -- Specifies the algorithm to use when decrypting the source object (e.g., 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 the encryption key was transmitted without error. Please note that this parameter is automatically populated if it is not provided.

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
  • Callback (method) -- 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.

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.

  • 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 ten bytes of the source. You can copy a range only if the source object is greater than 5 GB.
  • SSECustomerAlgorithm (string) -- Specifies the algorithm to use to when encrypting the object (e.g., AES256).

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 the encryption key was transmitted without error. Please note that this parameter is automatically populated if it is not provided.

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
  • Callback (method) -- 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.

  • GrantReadACP (string) -- Allows grantee to read the object ACL.
  • GrantWriteACP (string) -- Allows grantee to write the ACL for the applicable object.
  • 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 S3 (e.g., AES256, aws:kms).
  • StorageClass (string) -- The type of storage to use for the object. Defaults to 'STANDARD'.
  • 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.

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.

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.
  • Callback (method) -- 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.

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.

Acl()

Creates a ObjectAcl resource.:

object_acl = object.Acl()
Return type
S3.ObjectAcl
Returns
A ObjectAcl resource
Bucket()

Creates a Bucket resource.:

bucket = object.Bucket()
Return type
S3.Bucket
Returns
A Bucket resource
MultipartUpload(id)

Creates a MultipartUpload resource.:

multipart_upload = object.MultipartUpload('id')
Parameters
id (string) -- The MultipartUpload's id identifier. This must be set.
Return type
S3.MultipartUpload
Returns
A MultipartUpload resource
Version(id)

Creates a ObjectVersion resource.:

object_version = object.Version('id')
Parameters
id (string) -- The Version's id identifier. This must be set.
Return type
S3.ObjectVersion
Returns
A ObjectVersion resource

Waiters

Waiters provide an interface to wait for a resource to reach a specific state. For more information about waiters refer to the Resources Introduction Guide.

wait_until_exists(**kwargs)

Waits until this Object is exists. This method calls S3.Waiter.object_exists.wait() which polls. S3.Client.head_object() every 5 seconds until a successful state is reached. An error is returned after 20 failed checks.
