User Services

• You can re-use google's authentication:

import wsgiref.handlers

from google.appengine.api import users
from google.appengine.ext import webapp

class MainPage(webapp.RequestHandler):
  def get(self):
    user = users.get_current_user()

    if user:
      self.response.headers['Content-Type'] = 'text/plain'
      self.response.out.write('Hello, ' + user.nickname())
    else:
      self.redirect(users.create_login_url(self.request.uri))

def main():
  application = webapp.WSGIApplication(
                                       [('/', MainPage)],
                                       debug=True)
  wsgiref.handlers.CGIHandler().run(application)

if __name__ == "__main__":
  main()
