[SOLVED] GAE: python code to check if i'm on dev_appserver or deployed to appspot

GAE: python code to check if i'm on dev_appserver or deployed to appspot

My GAE app uses OAUTH 2. Currently, I manually switch the redirect_uri between http://localhost:8081/oauth2callback and myapp.appspot.com/oauth2callback depending on whether do local testing with dev_appserver or if I deploy to appspot.com.

Is there some code (e.g. using os.environ) that I can use to automate this?

Thanks!

Solution

You can get you current domain name with os.environ['SERVER_NAME'].

You also can check this by version name:

import os
if os.environ['APPLICATION_ID'].startswith('dev'):
  pass  # it's localhost
else:
  pass  # it's uploaded on gae

Will be better to use self.uri_for('callback-uri-name', _full=True) for building callback uri if you use webapp2.

You have something like this in your routes.

app = webapp2.WSGIApplication([
    webapp2.Route(r'/oauth/callback', handler='oauth.CallbackHandler', name='callback-uri-name'),
])

Then, if you'll call self.uri_for('callback-uri-name', _full=True) you'll get something like http://localhost:8080/oauth/callback or http://app-id.appspot.com/oauth/callback.
