We recommend that you use the latest version of this feature, which is renamed to Cloud Endpoints Frameworks for App Engine. This new version supports App Engine standard environment, provides lower latency, and has better integration with App Engine. For more details, see Migrating to 2.0.
Or if you use Maven and the artifacts described in the
Android Backend Tutorial
setup and configuration pages, your project automatically has the
appengine-web.xml generated with the proper entries.
Your project must contain, at a minimum, the following files:
|File and Location||Description|
||The class file (or files, if you implement your API across multiple classes) containing your backend API.|
||Optional file containing your API server code, if you don't include it inside your API class.|
||The web app deployment descriptor required for App Engine configuration.|
The contents of each of these required files is documented in the following sections.
The backend API class file
The API server file (Optional)
This file and its contents are fully described under Creating an API server.
The bare minimum contents required for this file are as follows:
runtime: python27 threadsafe: true api_version: 1 handlers: # The endpoints handler must be mapped to /_ah/spi. # Apps send requests to /_ah/api, but the endpoints service handles mapping # those requests to /_ah/spi. - url: /_ah/spi/.* script: main.api libraries: - name: pycrypto version: 2.6 - name: endpoints version: 1.0
mainis the name of the Python module and variable for your API server.
threadsafeis set to true if you want App Engine to send multiple requests in parallel, or set to false, if you want App Engine to send requests serially.
Additional but optional settings are available. See the
for more information. However, note that the information under Requiring login or administrator status and
Secure URLs do not apply to backend APIs.
