      Overview

      This API is used to delete a specified object. To call this API, you need to have permission to write to the object.
      

      Versioning

      To delete a specified version of object/delete marker, use the versionId request parameter to specify the ID of the object version/delete marker. In this way, the x-cos-version-id response header will be returned, indicating the version ID deleted.
      If versionId is not specified:
      When versioning is enabled, the DELETE operation will create the latest version of delete marker for this object, and the x-cos-version-id response header will be returned to indicate the version ID of the delete marker created in this request.
      When versioning is suspended, the DELETE operation will create a delete marker whose ID is null as the latest version of the object, and all other versions whose ID is null (if any) will be deleted.
      If the DELETE operation has successfully created/deleted a delete marker, the x-cos-delete-marker: true response header will be returned.
      For more information about the status (enabled/suspended) of versioning, please see Versioning Overview.
