Can I use GAE Cloud Endpoints from a desktop application?

Question

I want to write a desktop application that interacts with a GAE-based web service. For Android and Web clients there is the possibility to generate client libraries automatically. Is there a way to generate client libraries for C or C++? I would settle for Python as well.

Answer 1

Theoretically all the Google APIs Client libraries allow accessing any Discovery-based API as long as the discovery document is available (which is the case for cloud endpoints) even though the functionality isn't very well documented in most cases.

See https://developers.google.com/discovery/libraries for a list of currently available client libraries.

As example of how you can use the python client library with cloud endpoints:

service = build("your_api", "your_api_version", http=http, 
  discoveryServiceUrl=("https://yourapp.appspot.com/_ah/api/discovery/v1/"
                       "apis/{api}/{apiVersion}/rest"))

result = service.resource().method([parameters]).execute()

Currently, Google App Engine Cloud Endpoints only supports generating client libraries for Android (Java), iOS (Objective-C) and JavaScript. See https://developers.google.com/appengine/docs/java/endpoints/overview.

Of course you may still develop your application using GAE for your web service and write the web service interface libraries yourself in any language you choose.
