Obtaining Object Tags

Functions

This operation returns tags of an object.

If you do not specify a version ID in a request, make sure that you have the GetObjectTagging permission. If you do specify a version ID in a request, make sure that you have the GetObjectTagging and GetObjectVersionTagging permissions. By default, only the object owner can perform this operation. The object owner can grant this permission to others by using a bucket or user policy.

OBS returns the tags of the current object version by default. You can use the versionId parameter to retrieve tags of any other version. If the version you are retrieving tags from is a delete marker, OBS returns 404 Not Found.

Tags are not supported for files in parallel file systems.
