 def transform_request(self, orig_request, params, method_config):
 """Transforms orig_request to apiserving request. This method uses orig_request to determine the currently-pending request and returns a new transformed request ready to send to the backend. This method accepts a rest-style or RPC-style request. Args: orig_request: An ApiRequest, the original request from the user. params: A dictionary containing path parameters for rest requests, or None for an RPC request. method_config: A dict, the API config of the method to be called. Returns: An ApiRequest that's a copy of the current request, modified so it can be sent to the backend. The path is updated and parts of the body or other properties may also be changed. """
