This line should be parameter driven -- for authorization purposes, it's probably better to use 'https://www.googleapis.com/oauth2/v1/userinfo' if you want the primary account email address. To limit access to email-only, you'll also need to set the scope should be ' https://www.googleapis.com/auth/userinfo.email' .. Another thing -- if you want to use "https://www.googleapis.com/plus/v1/people/me", you need to enable this API service via the Google API settings.
