req.session.passport and req.user empty, serializeUser and deserializeUser are never called - node.js

Question

I'm using Express (v4.11.2) with Passport in order to support multiple providers (local, facebook, twitter and google) for access to the web app I'm building. As a backend I'm using mysql. For now I have two local strategies: local-signup and local-signin. The issue I'm experiencing is that the req.session.passport and req.user are always empty and that, in fact, serializeUser and deserializeUser are never being called.
Here is the setup of express and passport:
var bodyParser = require('body-parser');
var session = require('express-session');
var MemoryStore = session.MemoryStore;
var _ = require('underscore');
var passport = require('passport');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
app.use(session({
key: 'KEY',
secret: 'SECRET331156%^!fafsdaasd',
store: new MemoryStore({reapInterval: 60000 * 10}),
saveUninitialized: true,
resave: false
}));
app.use(passport.initialize());
app.use(passport.session());
require('./config/passport')(passport); // pass passport for configuration
and here is the passport file with authentication strategies:
module.exports = function (passport) {
passport.serializeUser(function (user, done) {
logger.info('SERIALIZE USER');
done(null, user.id);
});
passport.deserializeUser(function (id, done) {
logger.info('DESEIRALIZE USER!');
mysqllib.getConnection(function (err, connection) {
if (err) {
done(err);
}
var sql = "SELECT * FROM users WHERE idusers = ?";
logger.info('sql: ' + sql);
connection.query(sql, [id], function (err, rows) {
connection.release();
var user = {};
user.id = rows[0].idusers;
done(err, user.id);
});
});
});
passport.use('local-signup', new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true // allows us to pass back the entire request to the callback
},
function (req, email, password, done) {
logger.info('CALLING local-signup');
var firstname = req.body.firstname;
var lastname = req.body.lastname;
var role = req.body.role;
mysqllib.getConnection(function (err, connection) {
var sql = "INSERT INTO users VALUES(0, ?, ?, ?, ?, null, ?, 0, null, null, null, null, null, null, 0, 0)";
logger.info('sql: ' + sql);
connection.query(sql, [email, password, firstname, lastname, role], function (err, rows) {
connection.release();
if (err) {
if (err.code == 'ER_DUP_ENTRY') {
logger.info('er_dup_entry');
return done(err);
} else {
logger.info('general err');
return done(err);
}
} else {
logger.info('everything is OK!');
var user = {};
user.id = rows.insertId;
req.session.user_auth = user.id;
return done(null, user);
}
});
});
}));
passport.use(
'local-login',
new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true // allows us to pass back the entire request to the callback
},
function (req, email, password, done) {
mysqllib.getConnection(function (err, connection) {
if (err) {
logger.info('getConnection: ' + err);
return done(err);
}
var sql = "SELECT idusers, first_name, last_name, email, phone, dob, address, role, photo1, photo2, photo3, photo4, phonevalidated, uservalidated FROM users WHERE email = " + connection.escape(email) + " AND password = " + connection.escape(password);
connection.query(sql, function (err, rows) {
connection.release();
if (err) {
logger.error("select user", err);
return done(err);
} else if (rows.length) {
var user = rows[0];
user.id = rows[0].idusers;
return done(null, user);
} else {
logger.warn('Incorrect Login credentials, username: ' + email + ' password: ' + password);
return done(null, false, {message: 'unauthorized'});
}
});
});
})
);
};
and, for last, here is how I'm using the strategies in express routes:
app.post('/login', function (req, res, next) {
passport.authenticate('local-login', function (err, user, info) {
if (err) {
mysend(res, 500, 'Ups. Something broke!');
} else if (info) {
mysend(res, 401, 'unauthorized');
} else {
mysend(res, 200, JSON.stringify(user));
logger.info(req.user);
logger.info(req.session);
}
})(req, res, next);
});
Everything works fine, even in a strategy I can set the value of user's id in the session like this:
req.session.user_id = user.id
and continue to use it manually but I really don't get why serializeUser and deserializeUser aren't being called.

Answer 1

You need to call req.login() in custom callback which will then call serializeUser and set the user object to the session:
app.post('/login', function (req, res, next) {
passport.authenticate('local-login', function (err, user, info) {
if (err) {
mysend(res, 500, 'Ups. Something broke!');
} else if (info) {
mysend(res, 401, 'unauthorized');
} else {
req.login(user, function(err) {
if (err) {
mysend(res, 500, 'Ups.');
} else {
mysend(res, 200, JSON.stringify(user));
}
}
}
})(req, res, next);
});
