title: Google OAuth 2.0 what in the code paramater should i pass to my authentication function
body: <p>Hello I have an nodejs http server that if someone goes into <a href="http://www.example.com/login" rel="nofollow noreferrer">www.example.com/login</a> they get redirected to an google oauth2 url and then back at my site with a code.
  When a user gets back at my site with <a href="http://www.example.com/?code=4/SomeCodeHere&amp;scope=SomeScopeHere" rel="nofollow noreferrer">www.example.com/?code=4/SomeCodeHere&amp;scope=SomeScopeHere</a>
  I want to get what part of the url is the code needed for authentication and how should it be formatted %2 or / etc</p>
