How to redirect all URLs with Google App Engine

Question

How do I configure the app.yaml file to redirect all URLs to another URL? For example I want http://test.appspot.com/hello or http://test.appspot.com/hello28928723 to redirect to http://domain.com.

I am only serving static files at the moment. Here is my app.yaml file:

application: testapp version: 1 runtime: python api_version: 1  handlers: - url: (.*)/   static_files: static\1/index.html   upload: static/index.html  - url: /   static_dir: static 

Answer 1

Webapp2 has a built-in redirect handler

No need to roll your own handler; webapp2 already comes with one.

application = webapp2.WSGIApplication([     webapp2.Route('/hello', webapp2.RedirectHandler, defaults={'_uri':'http://domain.com'}),     webapp2.Route('/hello28928723', webapp2.RedirectHandler, defaults={'_uri':'http://domain.com'}), ], debug=False) 

The _uri argument is what the RedirectHandler class uses to define the destination. It took a lot of Google Fu to find the documentation on this but it works flawlessly in my app.

Update:

I assumed you're aware of this but you need to change your catch-all route from:

- url: /   static_dir: static 

To (python27 version):

- url: /.*   script: main.application 

Or: (pre python27 version)

- url: /.*   script: main.py 

main.py is the file containing the request handler + routes.

Note: There is no static-only way to handle redirects on GAE because of the nature of static files. Basically, there's no way to do a redirect in app.yaml alone.
