You can call this operation to query the tags of an object.
Versioning
By default, when you call GetObjectTagging to query the tags of an object, only the tags of the current version of the object are returned. You can specify the versionId parameter in the request to query the tags of a specified version of an object. If the current version of the object is a delete marker, OSS returns 404 Not Found.
