Method Details

bucket
The bucket name containing the object.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format
Bucket_name.s3express-az_id.region.amazonaws.com
. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the formatbucket_base_name--az-id--x-s3
(for example,DOC-EXAMPLE-BUCKET--usw2-az1--x-s3
). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.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.
Object Lambda access points - When you use this action with an Object Lambda access point, you must direct requests to the Object Lambda access point hostname. The Object Lambda access point hostname takes the form AccessPointName-AccountId.s3-object-lambda.Region.amazonaws.com.
Access points and Object Lambda access points are not supported by directory buckets.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form
AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com
. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.- Returns:
- The bucket name containing the object.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format
Bucket_name.s3express-az_id.region.amazonaws.com
. Path-style requests are not supported. Directory bucket names must be unique in the chosen Availability Zone. Bucket names must follow the formatbucket_base_name--az-id--x-s3

Object Lambda access points - When you use this action with an Object Lambda access point, you must direct requests to the Object Lambda access point hostname. The Object Lambda access point hostname takes the form AccessPointName-AccountId.s3-object-lambda.Region.amazonaws.com.
Access points and Object Lambda access points are not supported by directory buckets.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form
AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com
. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
