Is there a way to map GAE user object and Google+ userid
Question: As mentioned
[here](https://developers.google.com/appengine/docs/python/users/loginurls),
for default authentication using python users API an object will be returned
based on user's email. When `user_id()` is called over the object a unique id
is returned, which is of course not a Google+ user id.

    
    
    import webapp2
    from google.appengine.api import users
    
    class MainPage(webapp2.RequestHandler):
            def get(self):
                user = users.get_current_user()
                if user:
                    if users.is_current_user_admin():
                        utype = "Admin"
                    else:
                        utype = "Normal" 
                    self.response.headers['Content-Type'] = 'text/html'
                    self.response.out.write('Hello, ' + user.nickname() + ' Userid: ' + user.user_id() + ' User Type: ' + utype)
                else:
                    self.redirect(users.create_login_url(self.request.uri))
    
    app = webapp2.WSGIApplication([
                                    ('/', MainPage)
                                ], debug=False)

Basically, I need the plus id to retrieve some user details. (via [HTTP
GET](https://developers.google.com/+/api/latest/people/get))

Is there any available package in AppEngine API that can provide me with
google plus id for a logged in user's email?

Or should I move on to OAuth 2 for authentication purpose?

I have already completed 50% based on users API, so any help regarding the
same will be appreciated.


Answer: Yes, using their user.email()

To access properties of their Google+ profile you will need to use the Google
APIs Client Library for Python <https://developers.google.com/api-client-
library/python/start/installation>
