App Engine Python how to handle urls?

Question

Hi all,

I just want to ask a simple question, as I don't imagine how to do it.

In the app.yaml, when I want to declare query string parameter, how do I do it?

For example, to make a multi language site, I create the url in this format:

mysite.com/english/aboutus

mysite.com/italiano/aboutus

and in app.yaml the script to handle them are

- url: /english/aboutus
  script: index.py

- url: /italiano/aboutus
  script: index.py

In which way can I determine the difference between these two urls, and how to handle them in index.py?

I know this is simple question, I could look around for references, but it might help for others in stackoverflow.com as well.

Instead you could use the webapp framework to handle the URL's.

For example, in index.py

application = webapp.WSGIApplication(
                                 [('/english', EnglishHandler)],
                                 [('/italiano', ItalianHandler)],
                                 debug=True)

The SCRIPT_NAME environ entry contains the path under which your script was invoked. Haven't tested this in GAE specifically, but it's something WSGI inherited from CGI.

language= environ['SCRIPT_NAME'][1:].split('/', 1)[0]
if language not in ('english', 'italiano'):
    language= 'english'

I remember doing something like this:

in app.yaml put

- url: /(.*)/(.*)/?
  script: main.py

and in main.py

class MainHandler(webapp.RequestHandler):
     def get(self, Urlpart1, Urlpart2):

def main():
     application = webapp.WSGIApplication([('/(.*)/(.*)/', MainHandler),
                                         ('/(.*)/(.*)', MainHandler)], 
                                         debug=True)

where Urlparts are words between slashes

There're 39 human languages supported. Best way seems comply via lib/django/django/conf/locale/ Here's an app that translates all engines messages via parameter hl=[languageCode] [code disposable][2]
