Mapping URL Pattern to a Single RequestHandler in a WSGIApplication

Question

Is it possible to map a URL pattern (regular expression or some other mapping) to a single RequestHandler? If so how can I accomplish this?

Ideally I'd like to do something like this:

application=WSGIApplication([('/*',MyRequestHandler),])

So that MyRequestHandler handles all requests made. Note that I'm working on a proof of concept app where by definition I won't know all URLs that will be coming to the domain. Also note that I'm doing this on Google App Engine if that matters.

Answer 1

application=WSGIApplication([(r'.*',MyRequestHandler),])

for more see the AppEngine docs

Answer 2

The pattern you describe will work fine. Also, any groups in the regular expression you specify will be passed as arguments to the handler methods (get, post, etc). For example:

class MyRequestHandler(webapp.RequestHandler):
  def get(self, date, id):
    # Do stuff. Note that date and id are both strings, even if the groups are numeric.

application = WSGIApplication([('/(\d{4}-\d{2}-\d{2})/(\d+)', MyRequestHandler)])

In the above example, the two groups (a date and an id) are broken out and passed as arguments to your handler functions.
