I can't test a Google App using OpenID single sign-on on the AppEngine devserver, locally

I'm starting to develop an application using App Engine (Python) that will be integrated in the Google Apps platform and will be sold in the Marketplace. I've implemente开发者_StackOverflow中文版d the Single Sign-On openID authentication and it works fine when deployed, but doesn't work locally at all.

How can i do that locally? user.federated_identity() apparently does not work on the localhost.

--edit-- Precisely, what i need to do is to be able to run this tutorial on App Engine's devserver.

On localhost there's no point in verifying that the email matches the federated_id domain, so you should just add this to check_email:

def check_email(self, user):
  if os.environ.get('SERVER_SOFTWARE', '').startswith('Dev'):
    return True

It looks like if your consumer secret and key are set up correctly everything else should work and it will return the first entry from the calendar feed.
