Question

This is my app.yaml:

- url: /about|/about/.*
  script: about.py

This is my `about.py’:

application = webapp.WSGIApplication([(r'^/about$', AboutPage),
                                      (r'^/about/$', Redirect),
                                      (r'.*', ErrorPage)],
                                        debug = True)

I want to redirect all requests for /about/ to /about. I’d like all other requests to be sent to the error page.

It works in the development server on localhost, but I cannot access /about/ after I deployed the app on GAE – it just shows an empty page.

I adjusted the order of URL patterns in app.yaml.
It works now on GAE.

If you don’t want trailing slashes for GET requests anywhere in your application, you can implement a global redirect at the top of your app.yaml. Note that POST requests will NOT redirect, but this is ok (for me anyway) because users don’t generally hand-write POST URLs.

app.yaml:

application: whatever
version: 1
api_version: 1
runtime: python

handlers:
- url: .+/ 
  script: slashmurderer.py

slashmurderer.py

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

class SlashMurdererApp(webapp.RequestHandler):
   def get(self, url):
      self.redirect(url)

application = webapp.WSGIApplication(
   [('(.*)/$', SlashMurdererApp)]
)

def main():
   run_wsgi_app(application)
