I have a site dashboard on GAE standard node.js environment that uses login: admin option in handlers: element in my app.yaml file. This option makes google login window appear before accessing the site. Is it possible to get email and profile of user logged in?

• Tested on my local server

• I added login:required in app.yaml; it's a Python3 App but I did not use users api; I start the app with dev_appserver.py to make sure it uses the app.yaml file in the development environment; When I loaded the home page, it prompted me to sign in with [email protected]

• I dumped the header output and it included the following

   X-Appengine-User-Email: [email protected]
   X-Appengine-User-Id: XXXXX

Original Answer

1. You can use the 'users' Api and call the function GetCurrentUser()

Example, if your code was in python, you'd have something like

    from google.appengine.api import users

    # Get information about the currently logged in user
    users.GetCurrentUser()

    # Extra - if you wanted to confirm this is an admin user
    users.IsCurrentUserAdmin()

2. Since you're not using Python, see if the environment variable for USER_EMAIL exists. The source code for users api has the snippet below (so see if it works for you)

    email = os.environ.get('USER_EMAIL', email)
    _user_id = os.environ.get('USER_ID', _user_id)
