Extra - Directly get access_token and refresh_token on Server-side

To get access_token and refresh_token in server side, the data for redirect_uri should be postmessage. postmessage is magic value for redirect_uri to get credentials without actual redirect uri.

Curl

curl -d "client_id=YOUR_CLIENT_ID&\
  client_secret=YOUR_CLIENT_SECRET&\
  redirect_uri=postmessage&\
  grant_type=authorization_code&\
  code=YOUR_AUTH_CODE" https://accounts.google.com/o/oauth2/token
