I am trying to authenticate multiple user through multiple strategies. I have 2 table first is User table and second is employee but it's working when i try to login it show the error
User not exist
when i use just single authentication strategy it's work but when i use multiple strategy it shows error
Auth.js

new LocalStrategy({usernameField: "email"}, function (email, password, done) {
User.findOne({email: email})
.then(user => {
if (!user) {
return done(null, false, ({message: 'Email not exist'}))
}
bcrypt.compare(password, user.password, (err, isMatch) => {
if (err) throw err
if (isMatch) {
return done(null, user)
} else {
return done(null, false, ({message: 'Password incorrect'}))
}
})

I think you need to edit your .serializeUser() and .deserializeUser() functions so that passport knows what type of user you are trying to serialize and deserialize.
The way I have done it in the past is by using a SessionConstructor that puts both the user's id and the type of user they are inside an object. You can then use this in your deserialize function to figure out which usertype you are trying to sign in.
function SessionConstructor(userId, userGroup){
this.userId = userId;
this.userGroup = userGroup;
}
passport.serializeUser((user, done) => {
let userGroup = 'user';
if (//condition to tell if it is the other user type){
userGroup = 'employee';
};
let sessionConstructor = new SessionConstructor(user.id, userGroup)
done(null, sessionConstructor);
});
passport.deserializeUser((sessionConstructor, done) => {
if (sessionConstructor.userGroup == 'user'){
User.findById(sessionConstructor.userId).then(user => done(null, user));
} else if (sessionConstructor.userGroup == 'employee'){
Employee.findById(sessionConstructor.userId).then( employee=> done(null, employee));
}
});
You will however need to think of a condition for the if statement inside of .serializeUser() that will tell you which type of user it is. If you include a unique identifier inside of the user object that is sent to .serializeUser(), then you can check that to tell. For example have a key called employee inside your user object where the value is true if its an employee submitting it, and false otherwise. If you choose this implementation it would look something like this.
passport.serializeUser((user, done) => {
let userGroup = 'user';
if (user.employee){
userGroup = 'employee';
};
let sessionConstructor = new SessionConstructor(user.id, userGroup)
done(null, sessionConstructor);
});
Outisde of that I think the below code should work, but feel free to ask any questions about this method and I'll do my best to answer!
Here is a link to where I learned about how to do this.
I'm trying to deal with authentication sessions in Node.js, Express, Passport app.
I made lines of code to use express-session and it still can't auth even when I register new user.
Here is strategy.
// Local Strategy
passport.use(new LocalStrategy({ usernameField: 'email' }, function(username, password, done){
User.findOne({ 'email': username }, function(err, user){
if(err) throw err;
if(!user){
return done(null, false, {type: "danger", message: 'No user found'});
}
// Match Password
bcrypt.compare(password, user.password, function(err, isMatch){
if(err) throw err;
if(isMatch){
return done(null, user);
} else {
return done(null, false, {type: "danger", message: 'Wrong password'});
}
});
});
}));
Here are serializers.
passport.serializeUser(function(user, done) {
console.log(user.id);
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
console.log(user.id);
done(err, user);
});
});
Here is login and register route.
// Login page and form
router.get('/login', function(req, res) {
res.render('login');
});
router.post('/login', passport.authenticate('local',
{successRedirect: '/chat',
failureRedirect: '/login'}));
// Register page and form
router.get('/register', function(req, res) {
let errors = [];
res.render('register', { 'errors': '' });
});
router.post('/register', [
check('name').notEmpty().withMessage('Name field is empty'),
check('surname').notEmpty().withMessage('Surname field is empty'),
check('email').notEmpty().withMessage('E-mail is empty'),
check('password').notEmpty().withMessage('Password field is empty'),
check('password_confirm').notEmpty().withMessage('Password confirmation field is empty'),
check("password", "Passwords don't match")
.custom((value,{req}) => {
if (value !== req.body.password_confirm) {
throw new Error("Passwords don't match");
} else {
return value;
}
}),
], function(req, res) {
const { name, surname, email, password } = req.body;
let errors = validationResult(req);
console.log(errors.errors);
if(!errors){
res.render('register', { 'errors': errors.errors });
console.log('ebebe');
} else {
console.log('oooo');
let NewUser = new User ({
name, surname, email, password
});
bcrypt.genSalt(10, function(err, salt) {
bcrypt.hash(password, salt, function(err, hash) {
NewUser.password = hash;
NewUser.save();
});
});
res.redirect('/chat');
}
});
Here is protected route.
router.get('/chat', (req, res) => {
if(req.isAuthenticated()) {
res.send('definitely secure page');
console.log(req.user);
console.log(req.isAuthenticated());
} else {
res.send('ebebe');
console.log(req.user);
console.log(req.isAuthenticated());
}
});
How to make it work properly and what am I doing wrong?
Here is a way to do it. You can use something like jsonwebtoken in combination with express-session and write a middleware function to check if the token is valid and use it to protect the routes that you want to protect. Here are some snippets of code that I hope will help guide you in the right direction.
First you can write a function like this in your UserSchema so you can use it later to generate a jwt token when the user logs in
var jwt = require('jsonwebtoken');
UserSchema.methods.generateJWT = function() {
var today = new Date();
var exp = new Date(today);
exp.setDate(today.getDate() + 60);
return jwt.sign({
id: this._id,
username: this.username,
exp: parseInt(exp.getTime() / 1000),
}, secret);
};
then in the login route you can use it to generate a token.
router.post('/login', passport.authenticate('local',
failureRedirect: '/login'}), function(req, res) {
req.user.token = user.generateJWT();
req.session.token = req.user.token;
res.redirect('/dashboard')
});
and then you can write the middleware
function auth(req, res, next) {
//console.log(req.session.token)
if (req.session.token) {
const token = req.session.token
let decoded = jwt.verify(token, secret)
console.log(decoded)
User.findById(decoded.id, function(err, user) {
if (err || !user) {
return res.redirect('/')
}
//console.log(user)
res.locals.user = user
req.user = user
next()
})
} else {
return res.redirect('/')
}
}
and then you can protect your routes with it
router.get('/protected', auth, function(req, res) {
})
I'm trying to secure an API endpoint on a node.js express app that uses passport.
This is my route:
router.post('/api/devices', authController.isAuthorized, catchErrors(deviceController.getDevicesAPI));
This is my authorization method:
exports.isAuthorized = (req, res, next) => {
passport.authenticate('local', {session: false}, (err, user, info) => {
if (err || !user) {
return res.json({ message: 'Something is not right ', err, info });
}
req.login(user, {session: false}, (err) => {
if (err) {
res.send(err);
}
next();
});
})(req, res);
};
From Postman or a separate local server, I get the response:
{
"message": "Something is not right ",
"err": null,
"info": {
"message": "Missing credentials"
}
}
This is the Postman configuration:
What am I missing?
How is your local strategy configured? It seems like a database query problem
As the sample in http://www.passportjs.org/docs/username-password/, please see my comments below
var passport = require('passport')
, LocalStrategy = require('passport-local').Strategy;
passport.use(new LocalStrategy(
function(username, password, done) { //<--- Here is where you pass the UN&PASS
User.findOne({ username: username }, function(err, user) { //<--- Here is the sample code that should find you a user
if (err) { return done(err); } //<--- Here could be where the response is coming from
if (!user) {
return done(null, false, { message: 'Incorrect username.' });
}
if (!user.validPassword(password)) {
return done(null, false, { message: 'Incorrect password.' });
}
return done(null, user); //<--- Here is the sample code that should let you return that user
});
}
));
I finally dug it out from here. User.authenticate() is the method I was looking for.
exports.isAuthorized = async (req, res, next) => {
const username = req.body.username;
const password = req.body.password;
const user = await User.findOne({ email: username });
if (!user) {
res.sendStatus(403);
return;
}
user.authenticate(password, function(err, result) {
if (result) {
next();
return;
}
res.sendStatus(403);
});
};
I have this problem in the time i am in admin routes and i try to add a new article or a new image in my database , the same things happen even when i want to update something ....
this is my codes ?
exports.isAdmin = (req, res, next) => {
if (req.isAuthenticated() && res.locals.user.admin == 1) {
next();
} else {
req.flash("danger", "please log in as admin");
res.redirect("/users/login");
}
}
var LocalStrategy = require("passport-local").Strategy;
var User = require("../models/user");
var bcrypt = require("bcryptjs");
module.exports = function (passport) {
passport.use(new LocalStrategy(function (username, password, done) {
User.findOne({ username: username }, function (err, user) {
if (err)
console.log(err);
if (!user) {
return done(null, false, { message: "No user found" });
}
bcrypt.compare(password, user.password, function (err, isMatch) {
if (err) console.log(err);
if (isMatch) {
return done(null, user);
} else {
return done(null, false, { message: "Wrong password" });
}
})
});
}));
passport.serializeUser(function (user, done) {
done(null, user.id);
});
passport.deserializeUser(function (id, done) {
User.findById(id, function (err, user) {
done(err, user);
});
});
}
Anyone one can help the problem is i think in res.locals.user.admin but in other admin routes works ok but only when i want to add a new and edit a think happen this problem
I'm building an app in Node, using Passport and local signup and sign in strategies. I just keep running into an issue. All the required modules etc. are there. The following sign in routine works fine:
passport.use('local-signin', new LocalStrategy({
usernameField : 'email',
passwordField : 'password',
passReqTodone : true
}, function(req, email, password, done) {
User.findOne({ 'local.email' : email }, function(err, user) {
if (err)
return done(err);
if (!user)
return done(null, false, req.flash('message', 'User not found.'));
if (!user.validPassword(password))
return done(null, false, req.flash('message', 'Wrong password.'));
return done(null, user);
});
}));
However, the following sign up routine does not:
passport.use('local-signup', new LocalStrategy({
usernameField : 'email',
passwordField : 'password',
passReqTodone : true
}, function(req, email, password, done) {
console.log("signing up")
User.findOne({ 'local.email' : email }, function(err, user) {
if (err) {
return done(err);
} else if (user) {
return done(null, false, req.flash('message', 'That email address is already registered.'));
} else {
var newUser = new User();
}
// save the user
newUser.save(function(err) {
if (err) {
console.log("Error saving new user profile: " + err);
} else {
return done(null, newUser, req.flash('message', 'User account created'));
}
});
});
}))
Both routines are called within routes.js:
// POST : SIGNUP
app.post('/signup', passport.authenticate('local-signup', {
successRedirect: '/',
failureRedirect: '/error',
failureFlash: true
}));
// POST : SIGNIN
app.post('/signin', passport.authenticate('local-signin', {
successRedirect: '/profile',
failureRedirect: '/',
failureFlash: true
}));
Any ideas where it might go wrong? As is, posting to /signup continuously results in a failureRedirect. My head is getting kinda sore from banging on the screen...
The only thing you need to change is:
if (!user.validPassword(password))
To
if (user.validPassword(password) === false)
I know, if (!user.validPassword(password)) is in examples on Passport.js official docs, but it is wrong.
I have just lost 2 hours of my life, figuring this out.
Use this code it will helps you to fix your problem
passport-authentication.js
var express=require('express');
var router = express.Router();
var passport = require('passport');
var User = require('../models/user');//user is schema
var Verify = require('./verify');//verify is a file where the user is verified
/* GET users listing. */
router.get('/', Verify.verifyOrdinaryUser,function(req, res, next) {
User.find({},function(err,user){
if(err) throw err;
res.json(user);
});
});
router.post('/register', function(req, res) {
User.register(new User({ username : req.body.username,Email:req.body.Email}),
req.body.password, function(err, user) {
if (err) {
return res.status(500).json({err: err});
}
if(req.body.firstname) {
user.firstname = req.body.firstname;
}
if(req.body.lastname) {
user.lastname = req.body.lastname;
}
user.save(function(err,user) {
passport.authenticate('local')(req, res, function () {
return res.status(200).json({status: 'Registration Successful!'});
});
});
});
});
router.post('/login', function(req, res, next) {
passport.authenticate('local', function(err, user, info) {
if (err) {
return next(err);
}
if (!user) {
return res.status(401).json({
err: info
});
}
req.logIn(user, function(err) {
if (err) {
return res.status(500).json({
err: 'Could not log in user'
});
}
var token = Verify.getToken(user);
res.status(200).json({
status: 'Login successful!',
success: true,
token: token
});
});
})(req,res,next);
});
router.get('/logout', function(req, res) {
req.logout();
res.status(200).json({
status: 'Bye!'
});
});
module.exports = router;
verify.js
var User = require('../models/user');
var jwt = require('jsonwebtoken'); // used to create, sign, and verify tokens
var config = require('../config.js');
exports.getToken = function (user) {
return jwt.sign(user, config.secretKey, {
expiresIn: 3600
});
};
exports.verifyOrdinaryUser = function (req, res, next) {
// check header or url parameters or post parameters for token
var token = req.body.token || req.query.token || req.headers['x-access-token'];
// decode token
if (token) {
// verifies secret and checks exp
jwt.verify(token, config.secretKey, function (err, decoded) {
if (err) {
var err = new Error('You are not authenticated!');
err.status = 401;
return next(err);
} else {
// if everything is good, save to request for use in other routes
req.decoded = decoded;
next();
}
});
} else {
// if there is no token
// return an error
var err = new Error('No token provided!');
err.status = 403;
return next(err);
}
};
hope this helps for you...
