title: Access URI Parameters via webapp2
body: <p>I want to access the URI parameters of the given request:    </p>
  
  <pre><code>http://localhost:8080/account/user?un=erik&amp;pw=gaius
  </code></pre>
  
  <p>I can't make the following code work though,</p>
  
  <p><strong>main.py</strong>      </p>
  
  <pre><code>app = webapp2.WSGIApplication([('/', MainPage),
                                 ('/account/user', account.User)],
                                debug=True)
  </code></pre>
  
  <p><strong>account.py</strong></p>
  
  <pre><code>class User(webapp2.RequestHandler):
    def get(self, un, pw):
      self.response.headers['Content-Type'] = 'text/plain'
      self.response.write('Yey!' + un + ' ' + pw)
  </code></pre>
  
  <p>I think there's something wrong on my main.py, but I tried to mess with it by adding named routes and regex's, but I just kept getting 500 errors (Internal Server error). </p>
