Google oauth not returning email passport authentication

问题

I am trying to make a sign in with google button using passport module of node js. I am trying to get person's email id, name, profile pic. I am trying to download pic to local server. Google is not returning email id even after adding 'email' to scope and nor the returned link for profile pic is working. I have looked into various answers to this question but all say to include userinfo.email. It has been deprecated now. As per google documentation new scope parameter is email.

Below is my code. Any help is appreciated.

Passport

passport.use(new GoogleStrategy({

    clientID        : configAuth.googleAuth.clientID,
    clientSecret    : configAuth.googleAuth.clientSecret,
    callbackURL     : configAuth.googleAuth.callbackURL,
},
function(token, refreshToken, profile, done) {

    // make the code asynchronous
    // User.findOne won't fire until we have all our data back from Google
    process.nextTick(function() {

        // try to find the user based on their google id
        User.findOne({ 'google.id' : profile.id }, function(err, user) {
            if (err)
                return done(err);

            if (user) {

                // if a user is found, log them in
                return done(null, user);
            } else {
                // if the user isnt in our database, create a new user
                var newUser          = new User();
                console.log(profile);
                //JSON.parse(profile);
                // set all of the relevant information
                newUser.google.id    = profile.id;
                newUser.google.token = profile.token;
                newUser.google.name  = profile.displayName;
                newUser.google.uname = profile.emails[0].value; // pull the first email
                newUser.google.dp    = profile._json.picture;
                console.log('url is');
                console.log(newUser.google.name);
                console.log(newUser.google.dp);
                //console.log(profile.picture);
                Download(newUser.google.uname, newUser.google.dp,function(err){
                    if(err)
                        console.log('error in dp');
                    else
                        console.log('Profile Picture downloaded');
                });

                // save the user
                newUser.save(function(err) {
                    if (err)
                        throw err;
                    return done(null, newUser);
                });
            }
        });
    });

}));
};

routes.js

    app.get('/connect/google', passport.authorize('google', { scope : ['profile', 'email'] }));

    // the callback after google has authorized the user
    app.get('/connect/google/callback',
        passport.authorize('google', {
            successRedirect : '/profile',
            failureRedirect : '/'
        }));

download.js

    module.exports = function(username, uri, callback){
var destination;

request(uri).pipe(fs.createWriteStream("./downloads/"+username+".png"))
.on('close', function(){
    console.log("saving process is done!");
});

I had the same problem and wrote the scope in this way:

app.get('/connect/google', passport.authenticate('google', {
    scope: [
        'https://www.googleapis.com/auth/userinfo.profile',
        'https://www.googleapis.com/auth/userinfo.email'
    ]
}));

And you will get the email:

function(accessToken, refreshToken, profile, done) {
    console.log(profile.emails[0].value);
}); 

I hope this helps you.

The above answer definitely works, there is also one more way to approach this.

app.get('/auth/google',
  passport.authenticate('google', { scope: ['profile', 'email'] })
);

In your routes.js with the profile add email.

This should resolve your issue.

According to google documentation for oauth, the first parameter has to be openid and the second can be email or profile, or both

app.get('/auth/google',
    passport.authenticate('google', {scope: ['openid', 'email', 'profile']})
);
