Question

my app.yaml:

handlers:
  - url: /static
    static_dir: static

  - url: /.*
    script: main.app

is there a way, inside my webapp2 code, to get the absolute URL of the /static route?

Answer 1

When you define routes in your application you can compute an uri. See: http://webapp-improved.appspot.com/guide/routing.html#building-uris
With this information and your knowledge of the app.yaml you can compute the uri for the static url.

In your main.app you add a dummy route definition for static. It will only be used to build the uri and it will never be used for routing.

Modified example from the webapp2 docs :

app = webapp2.WSGIApplication([
    webapp2.Route('/', handler='HomeHandler', name='home'),
    webapp2.Route('/static', handler=HomeHandler, name='static'), # never used for routing
])
