google example totally old and wrong.

The google api changed the endpoint that can be used with oauth, the endpoint in the example
the line:
resp = google.get("/plus/v1/people/me")
return an error with:

AssertionError: {
  "error": {

  }

I'm trying to understand the correct endpoint, but it seems that google have changed them, and it is really difficult for beginners to figure out how to fix it. Please, could you check for the specific case of GOOGLE auth, a simple COMPLETE example, and maybe give a repository that is just working ? (by just writing the correct client_id,client_secret). I've followed the example with git, and it works, but out there the majority of users have a google account, so please I think that a simple code that works with google auth, is really really really important for beginners.
I'm trying to do it in the last week, without ANY success.
