      Overview

      This API is used to query the existing tags of an object.
      If a sub-account needs to call this API (GET Object tagging), ensure that the root account has authorized it to do so.

      Versioning

      If you have enabled versioning for the bucket and want to query the tags of an object of a specified version, include the VersionId parameter in the request.

      Request

      Sample request

      Host:<BucketName-APPID>.cos.<Region>.myqcloud.com

      Note:
