get_object_acl#

S3.Client.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.

Request Syntax

response = client.get_object_acl(
    Bucket='string',
    Key='string',
    MirrorDestination='string',
    VersionId='string',
    RequestPayer='requester',
    ExpectedBucketOwner='string'
)

Parameters:

Bucket (string) –
[REQUIRED]

The bucket name that contains the object for which to get the ACL information.

Access points - When you use this action with 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 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.
Key (string) –
[REQUIRED]

The key of the object for which to get the ACL information.
MirrorDestination (string) – Mirror source for object reads.
VersionId (string) – VersionId used to reference a specific version of the object.
RequestPayer (string) – Ignored by COS if present.
ExpectedBucketOwner (string) – Ignored by COS if present.
