google oauth problem
Following steps at https://developers.google.com/accounts/docs/OAuth2WebServer
Step 1. submit a get request to the google api endpoint, below is example of my (seemingly) correctly formed get request
https://accounts.google.com/o/oauth2/auth?response_type=code&scope=https://mail.google.com/+https://www.googleapis.com/auth/userinfo.email+https://www.googleapis.com/auth/userinfo.profile&client_id=XXXXXXXXXXXX.apps.googleusercontent.com&redirect_uri=http://localhost:4567/oauth2callback&access_type=online
Step 2. receive a callback that contains an authorization code, below is the url I'm receiving back.
http://localhost:9393/oauth2callback?code=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
