I am trying to login website with hello.js. I get the user name but I can't get user email id. How can I get this?

I am following this link.

This is my code :

hello.on('auth.login', function(auth) {

    // Call user information, for the given network
    hello(auth.network).api('/me').then(function(r) {       
        console.log("r.email = "+r.email);
        console.log("r.name== = "+r.name);

Answer 1

I got my problem solved by simple changing in the hello.js.

for google :-

scope: {                
        basic: 'https://www.googleapis.com/auth/plus.me profile',
       }

to

scope: {                
        basic: 'https://www.googleapis.com/auth/userinfo.email',
       }

for facebook :-

scope: {                
        basic: 'public_profile',
       }

to

scope: {                
        basic: 'public_profile,email',
       }
