Question

I have a scenario where a client (mobile app) would send an update query to my GAE website to see if the website has a newer version of a resource and if it does it would return this resource (zip-file) otherwise it would just return a json response “all up to date” (or perhaps a Not Modified 304 HTTP response code)

How should the REST URL look (coming from the mobile app)?

www.example.com/update?version=(client_version)

OR

www.example.com/update_client_version

Thankful for any help I can get.

What I have so far is… but I’m getting a 404 for some reason when doing http://localhost:8080/update/1

class UpdateHandler(webapp2.RequestHandler):

        if version == latestVersion:
            self.response.write('You are using latest version')
        else:
            self.response.write('You are not using latest version')


app = webapp2.WSGIApplication([('/update/(.*)', UpdateHandler)], debug=True)

I would go with the following approach:

http://www.example.com/update/client_version

Your code should look like this:

import webapp2

class UpdateHandler(webapp2.RequestHandler):
    def get(self, version):
        # Do something for version

app = webapp2.WSGIApplication(
    [(r'/update/(\d+)', UpdateHandler)], 
    debug=True)
