Google Authentication using Sails.js - mysql

Question

When I have tried to implement Google authentication in my site, using sails JavaScript, and MySQL getting error. I have using passport and passport-Google-auth Strategy. Problem is not getting data to my site from Google
My Express Config(express.js) file is like below,
var passport = require('passport')
, GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
var verifyHandler = function(token, tokenSecret, profile, done) {
process.nextTick(function() {
console.log(profile)
User.findOne({uid: profile.id}, function(err, user) {
if (user) {
return done(null, user);
} else {
var data = {
provider: profile.provider,
uid: profile.id,
name: profile.displayName
};
if (profile.emails && profile.emails[0] && profile.emails[0].value) {
data.email = profile.emails[0].value;
}
if (profile.name && profile.name.givenName) {
data.firstname = profile.name.givenName;
}
if (profile.name && profile.name.familyName) {
data.lastname = profile.name.familyName;
}
User.create(data, function(err, user) {
return done(err, user);
});
}
});
});
};
passport.serializeUser(function(user, done) {
console.log(user)
done(null, user.uid);
});
passport.deserializeUser(function(uid, done) {
User.findOne({uid: uid}, function(err, user) {
done(err, user);
});
});
module.exports.http = {
customMiddleware: function(app) {
passport.use(new GoogleStrategy({
clientID: 'Client Id here',
clientSecret: 'Secret key here',
callbackURL: 'http://localhost:1337/auth/google/callback'
}, verifyHandler));
app.use(passport.initialize());
app.use(passport.session());
}
};
module.exports.cache = {
// The number of seconds to cache files being served from disk
// (only works in production mode)
maxAge: 31557600000
};
module.exports.userlogin = {
userModel: 'user'
};
And My Auth Controller I have added code like below,
google: function(req, res) {
passport.authenticate('google',{
failureRedirect: '/login', scope: ['profile', 'email']
}, function(err, user) {
req.logIn(user, function(err) {
if (err) {
console.log(err);
res.view('500');
return;
}
res.redirect('/');
return;
});
})(req, res);
},

You didn't post your code, so we can't find the exact problem :/
I usually use this method for google/facebook authentication with sails.js.
I follow at first this documentation to add the authentication buttons in the frontend:
https://developers.google.com/identity/sign-in/web/sign-in
Then I post the token that I got from google/facebook to the backend where I can check if the user is banned or whatever... If everything is correct, I create an account for him in the database, I send him his password to his email and finally authenticate him using sessions
(req.session.userId = createdUser.id)
In the next time the user can log in using his email and password or just using google. And both options lead him to the same account :D
My Sails.js function in the authentication controller:
googleAuth: function(req, res) {
if (_.isUndefined(req.param('googleToken'))) {
return res.json({
success: false,
msg: 'Error! Please post your google token'
});
}
var urlToRq = "https://www.googleapis.com/oauth2/v3/tokeninfo?id_token=" + req.param('googleToken');
// Get information about the google user with the specified access token.
request.get({url: urlToRq}, function(err, response, body) {
if(err) {
return res.json({
success: false,
msg: 'Server Error'
});
}
var receivedData = JSON.parse(body);
var userId = receivedData.sub;
var userEmail = receivedData.email;
var emailVerified = receivedData.email_verified;
var userName = receivedData.name;
var userPicture = receivedData.picture;
if (emailVerified == false) {
return res.json({
success: false,
msg: 'Your email is not verified'
});
}
else {
// AUTHENTICATION VERIFIED, YOU CAN SAVE THE CONNECTED USER IN A SESSION, OR ADD HIM TO THE DATABASE AS A NEW ACCOUNT, OR CHECK IF HE HAS A PREVIOUS ACCOUNT OR WHATEVER YOU WANT...
}
});
},
Of course don't forget to run npm install request --save
If anyone needs the facebookAuth function just tell me :D I will post it for you :)
