This API is used to delete multiple objects (up to 1,000) from a bucket in a single request. COS provides the following two response modes:
To call this API, you need to have permission to write to the bucket.
If versioning is enabled, you can specify a version ID for each object to delete so that these objects/delete markers of the specified versions can be deleted permanently. If no version ID is specified, a new delete marker will be created for the object.
If a delete marker is created or deleted in this request, the &dxlt;DeleteMarker>true&dxlt;/DeleteMarker&dxgt; and &dxlt;DeleteMarkerVersionId&dxgt; nodes will be returned for this object.
If an object of a specified version (including the delete marker version) is deleted permanently in this request, the &dxlt;VersionId&dxgt; node will be returned, indicating the version ID that is deleted in this request.
