AmazonS3Client.RenameObject (RenameObjectRequest)

Method

Renames an existing object in a directory bucket that uses the S3 Express One Zone storage class. You can use RenameObject by specifying an existing object’s name as the source and the new name of the object as the destination within the same directory bucket.

RenameObject is only supported for objects stored in the S3 Express One Zone storage class.

To prevent overwriting an object, you can use the If-None-Match conditional header.

• If-None-Match - Renames the object only if an object with the specified name does not already exist in the directory bucket. If you don't want to overwrite an existing object, you can add the If-None-Match conditional header with the value ‘*’ in the RenameObject request. Amazon S3 then returns a 412 Precondition Failed error if the object with the specified name already exists. For more information, see RFC 7232.

Permissions

To grant access to the RenameObject operation on a directory bucket, we recommend that you use the CreateSession operation for session-based authorization. Specifically, you grant the s3express:CreateSession permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession API call on the directory bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession API call to generate a new session token for use. The Amazon Web Services CLI and SDKs will create and manage your session including refreshing the session token automatically to avoid service interruptions when a session expires. In your bucket policy, you can specify the s3express:SessionMode condition key to control who can create a ReadWrite or ReadOnly session. A ReadWrite session is required for executing all the Zonal endpoint API operations, including RenameObject. For more information about authorization, see CreateSession. To learn more about Zonal endpoint API operations, see Authorizing Zonal endpoint API operations with CreateSession in the Amazon S3 User Guide.
