GetBucketAcl
Note
This operation is not supported for directory buckets.
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 the 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.
When you use this API operation with an access point, provide the alias of the access point in place of the bucket name.
When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name.
If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned.
For more information about InvalidAccessPointAliasError, see List of
Error Codes.
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.
