I have an express app that I am trying to authenticate with passport-local. Here is my express app:
app.use(express.bodyParser());
app.use(express.cookieParser());
app.use(express.session({ secret: 'this is a string' }));
app.use(passport.initialize());
app.use(passport.session());
client = new pg.Client(connectionString);
client.connect();
passport.use(new LocalStrategy(
function(username, password, done) {
var query = client.query('SELECT * FROM users WHERE EMAIL = $1', [username], function(err, result){
if(err) {
console.log("Error");
return done(err);
}
if(!result.rows.length > 0) {
console.log("No users");
return done(null, false, { message: 'User not found'});
}
if(result.rows[0].password !== password) {
console.log("incorrect password");
return done(null, false, { message: 'Password Incorrect'});
}
console.log('authenticated');
return done(null, result.rows[0]);
});
}
));
passport.serializeUser(function(user, done) {
'use strict';
console.log('serialize');
console.log(user);
done(null, user.email);
});
passport.deserializeUser(function(id, done) {
'use strict';
console.log('deserialize');
User.findById(id, function(err, user) {
done(err, user);
});
});
app.post('/login', passport.authenticate('local'), function(req, res) {
'use strict';
console.log(req.user.username);
});
app.listen(port, function() {
'use strict';
console.log('Listening on:', port);
});
I then hit the /login url with this json in my body: {username: 'jason#gmail.com', password: 'password }. I go through the LocalStrategy function and then in the serialize function it makes it to the done function and then just hangs. I get no errors or additional logging, the connection just stays open and control is not given back to the caller. I never receive a http status, it just hangs.
I think it is a problem with my session, but I do not understand what to do next?
Ok, could you try a redirect there? It looks like your session / auth is ok, if you get a proper username at that point.
app.post('/login', passport.authenticate('local', {
successRedirect: '/somewhere_intern',
failureRedirect: '/login'
}));

I have a tremendous headche with a problem when I try to login using Passport.
I'm making a post request to /login with an email and password. Passport authenticates it correctly, err isn't called and then return res.redirect('/user') gets called too but it returns 404 and doesn't redirect.
I don't know why this is happening. Here's my code:
Server (index.js):
const
express = require('express'),
app = express(),
mongoose = require('mongoose'),
passport = require('passport'),
cookieSession = require('cookie-session'),
bodyParser = require('body-parser'),
keys = require('./config/keys'),
user = require('./models/User'),
passportService = require('./services/passport'),
authRoutes = require('./routes/auth');
mongoose.connect(keys.mongoURI);
app.use(bodyParser.json());
app.use(
cookieSession({
maxAge: 15 * 24 * 60 * 60 * 1000,
keys: [keys.cookieKey]
})
);
app.use(passport.initialize());
app.use(passport.session());
passportService(passport);
authRoutes(app);
const PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
console.log(`App listening on port ${PORT}`);
});
passportService (passport.js):
const LocalStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');
const User = mongoose.model('users');
module.exports = (passport) => {
passport.serializeUser((user, done) => {
done(null, user._id);
});
passport.deserializeUser((id, done) => {
User.findById(id).then(user => {
done(null, user);
});
});
passport.use(
new LocalStrategy(
{
usernameField: 'emailaddr',
passwordField: 'passwd'
},
function(username, password, done) {
User.findOne({ email: username }, function(err, user) {
if(err){
return done(err);
}
if(!user) {
console.log('User not found with email: ', username);
return done(null, false);
}
if(user.password != password) {
console.log('Invalid password');
return done(null, false)
}
return done(null, user);
});
}));
}
Authentication route:
const passport = require('passport');
module.exports = app => {
app.post('/api/login', function(req, res, next) {
passport.authenticate('local', function(err, user, info) {
if (err) { return next(err); }
if (!user) { return res.redirect('/login'); }
req.logIn(user, function(err) {
if (err) { return next(err); }
return res.redirect('/user');
});
})(req, res, next);
});
}
There is not route for /user because I'm working with React and React Router in the client.
Please I need your help!!!
I would suggest not using the custom callback on your authenticate function. Instead, check to see if after the api is called and authentication is run if you have a user attached to the request object.
// calling redirects from your api will be problematic with react router
// allow your front end to decide what route to call based on the response
app.post('/api/login', passport.authenticate('local'), function(req, res, next) {
if(req.user) {
res.json(req.user);
} else {
// handle errors here, decide what you want to send back to your front end
// so that it knows the user wasn't found
res.statusCode = 503;
res.send({message: 'Not Found'})
}
});
Note: there are many similar questions but I've gone through all of them and none of the solutions work.
Hi,
I've tried every solution on the net, bug still persists.
I'm building a simple CRUD app, and I'm currently struggling with passportjs's req.isAuthenticated().
The user is definitely being authenticated, as console.log(req.user) in passport.authenticate returns the user object, and req.session.passport has the user id.
After the redirect though, even if the redirect is async, user is undefined and req.session.passport is empty. It's as if the session is reset.
Here's the code:
app.js
var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');
var session = require('express-session');
var passport = require('passport');
var flash = require('connect-flash');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: false
}));
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use(express.static(path.join(__dirname, 'public')));
app.use('/bootstrap', express.static(path.join(__dirname + '/node_modules/bootstrap/dist')));
app.use(session({
secret: 'keyboard cat',
resave: true,
saveUninitialized: true,
cookie: {
maxAge: 5 * 60 * 1000
}
}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
app.use(function(req, res, next) {
res.locals.messages = require("express-messages")(req, res);
next();
});
app.get('*', function(req, res, next) {
console.log(req.method, ":", req.url);
res.locals.user = req.user || null;
next();
});
app.use("/", index);
app.use("/users", users);
var port = 4000;
app.listen(port);

I would really appreciate some help, as this is seems to be a common bug, but none of the workarounds work for me.
This seems to be related to the method you are using to store the user creds. Please note, Chrome and IE have different quirks about local vs session storage. Try this in chrome, Passport JS will store the response in either Local or Session storage - you should interrogate those storage mechanisms to verify the user's credentials are in them.
In chrome, go to the F12 debug tools and look in your session and local storage:
Please let us know the browser you are using, and if using Chrome makes a difference.
Hello SO wonderful users
I am having trouble with passport js since two days and cant figure it out.
Passport Strategy is not being called.
the console.log is not being called!
any ideas ?
here is my code
//init.js
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
module.exports = function(app) {
passport.use(new LocalStrategy(function(username, password, done) {
console.log(username, password);
return done(null, {username: 'agent'});
}));
passport.serializeUser(function(user, done) {
done(null, 'agent');
});
passport.deserializeUser(function(id, done) {
done(null, {username: 'agent'});
});
app.use(passport.initialize());
};
//routes.js
var passport = require('passport');
module.exports = function(app) {
app.get('/login', function(req, res) {
res.send('login');
});
app.post('/login', function(req, res, next) {
passport.authenticate('local', function(err, user, info) {
if (err) {
return next(err);
}
if (!user) {
console.log(user);
console.log('no user');
return res.redirect('/login');
}
req.logIn(user, function(err) {
if (err) {
return next(err);
}
return res.redirect('/');
});
})(req, res, next);
});
//index.js, where i call the auth
require('./src/auth/init')(app);
require('./src/auth/routes')(app);
edit
solution
the issue was with postman, I hade to change the body post data to x-www-form-urlencoded
I am using Passport js for authentication in my project. At server side i am using Express js. In app.js i have configuration for passport js and the code is:
passport.use(new Strategy({
passReqToCallback: true
},
function (req, username, password, done) {
req.models.users.find({ 'user_id' : username }, function (err, user) {
if (err) { return done(err); }
if (!user[0]) {
console.log("The username is Incorrect");
return done(null, false, { message: 'Incorrect username.' });
}
if (user[0].default_password!=password) {
console.log("The Password is Incorrect");
return done(null, false, { message: 'Incorrect password.' });
}
return done(null, user);
});
}
));
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(user, done) {
done(null, user);
});
and after this i am verifying the client request like this:
app.post('/login',
passport.authenticate('local', { failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
Till here everything is working fine.
Now i want to place this route app.post('/login',... in routes folder so i have given the path of the route in app.js like this:
var users = require('./routes/users/users');
app.use('/users', users);
My problem is: in this user route file i don't have passport configuration and i don't want to rewrite it again for all my other routes so i am thinking to place the passport configuration in a common file and reuse it but i don't know how to do it. If you have any idea please help. Thanks.
You can write a middleware, lets call it auth.js, that checks for session info and mount this for every route that you need.
'use strict';
const qs = require('querystring'),
router = require('express').Router();
router.use(function (req, res, next) {
// set this in res.locals
if (!req.user) {
return res.redirect('/?' + qs.stringify({
'r': req.originalUrl
}));
}
next();
});
module.exports = router;
If you use the above approach, you will need to add res.locals.user = req.user; in your server/app.js.
After this, you can require the above middleware on every route that needs to be authenticated.
router.verb('/path', require('./path-to-auth'));
router.verb('/path', (req, res, next) => {
// this route will only be executed if the user is authenticated
});
I have some trouble implementing passport-local on my NodeJS application. I don't understand what I'm doing wrong here. I'll list the important code for this question here.
app.js:
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(passport.initialize());
app.use(passport.session());
users.js:
var express = require('express');
var router = express.Router();
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var User = require('../models/user.js');
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.getUserById(id, function(err, user) {
done(err, user);
});
});
passport.use(new LocalStrategy(
function(username, password, done) {
console.log('Entered passport'); // This doesn't even happen
User.getUserByUsername(username, function(err, user) {
if (err) throw err;
if (!user) {
console.log('Unknown User');
return done(null, false, {
message: 'Unknown User'
});
}
User.comparePassword(password, user.password, function(err, isMatch) {
if (err) throw err;
if (isMatch) {
return done(null, user);
}
console.log('Invalid Password');
return done(null, false, {
message: 'Invalid Password'
});
});
return done(null, user);
});
}
));
router.post('/login', passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/users/login',
failureFlash: 'Invalid username or password'
}), function(req, res) {
console.log("Authentication Successfull!");
req.flash('success', 'You are logged in');
res.redirect('/');
});
user.js (Model):
module.exports.getUserByUsername = function(username, callback) {
var query = { username: username };
User.findOne(query, callback);
}
module.exports.getUserById = function(id, callback) {
User.findById(id, callback);
}
module.exports.comparePassword = function(candidatePassword, hash, callback) {
bcrypt.compare(candidatePassword, hash, function(err, isMatch) {
if(err) return callback(err);
callback(null, isMatch);
});
}
I'm not getting any syntax errors. In users.js I want to log a message to the console, but it doesn't even get there. The post function on the login gets fired when I just enter a function with a console.log there, but now it seems that it doesn't. It just reloads the page (looks like it). Any help is appreciated.
try to mount session middleware before passport initilized:
var session = require('express-session')
app.use(session({ secret: 'xxxxxxx' }));
app.use(passport.initialize());
app.use(passport.session());
