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...
I'm making a form login by passportJs and it always return failureRedirect. I have search in stack overflow for this issue, but still not have the correct answer. Here is my code:
Form making form jade:
form(method='post', action='/users/login', enctype='multipart/form-data')
.form-group
label Username
input.form-control(name='username', type='text' placeholder='Enter Username')
.form-group
label Password
input.form-control(name='password', type='password' placeholder='Enter password')
input.btn.btn-default(name='submit', type='submit', value='Login')
Router Hanlde is using express framework form Nodejs and passport middleware:
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({
usernameField: 'username',
passwordField: 'password'
},
function(username, password, done) {
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);
} else {
console.log('Invalid Password');
return done(null, false, {
message: 'Invalid Password'
});
}
});
});
}
));
router.post('/login', passport.authenticate('local', {
failureRedirect: '/users/login',
failureFlash: 'Invalid username or password'
}), function(req, res) {
console.log('Authentication Successful');
req.flash('success', 'You are logged in ');
res.redirect('/');
});
Looking at getUserByUsername function you shared in comments, it looks like you are not making call to callback function of getUserByUsername in correct way and therefore it is not getting user object resulting into failure redirect. The function you shared was:
module.exports.getUserByUsername = function(username, callback){
var query = {username: username};
User.findOne(query, callback);
}
Changing it to following should fix your issue:
module.exports.getUserByUsername = function(username, callback){
var query = {username: username};
User.findOne(query, function(err, user) {
callback(err, user);
});
}
Is there any way to allow a user to register on the local strategy with his password, email and name?
Every example I could find online only use name/password or email/password.
I also searched through the the whole passport documentation, but that documentation isn't helpful at all. It's just one bloated site full of examples.
I just need an list of functions, classes and variables passport uses with explanations what they and every parameter of them do. Every good library has something like that, why can't I find it for passport?
Here are the key parts of my code:
passport.use('local-signup', new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
//are there other options?
//emailField did not seem to do anything
passReqToCallback: true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
},
function(req, email, password, done) {
//check if email not already in database
//create new user using "email" and "password"
//I want an additional parameter here "name"
}));
So is passport really that limited? There has to be a way to do this, right?
You can be a little confused but passport doesn't implement signup methods. It's just authorisation library. So you must handle that use-case on your own.
First of all, create route that will be responsible for sign-up and your checks:
signup: function (req, res) {
User
.findOne({
or: [{username: req.param('username')}, {email: req.param('email')}]
})
.then(function(user) {
if (user) return {message: 'User already exists'};
return User.create(req.allParams());
})
.then(res.ok)
.catch(res.negotiate);
}
The example above is based on Sails framework, but you can fit it with no problems to your own case.
Next step is include passport local strategy.
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var LOCAL_STRATEGY_CONFIG = {
usernameField: 'email',
passwordField: 'password',
session: false,
passReqToCallback: true
};
function _onLocalStrategyAuth(req, email, password, next) {
User
.findOne(or: [{email: email}, {username: email}])
.then(function (user) {
if (!user) return next(null, null, {
code: 'E_USER_NOT_FOUND',
message: email + ' is not found',
status: 401
});
if (!HashService.bcrypt.compareSync(password, user.password)) return next(null, null, {
code: 'E_WRONG_PASSWORD',
message: 'Password is wrong',
status: 401
});
return next(null, user, {});
})
.catch(next);
}
passport.use(new LocalStrategy(LOCAL_STRATEGY_CONFIG), _onLocalStrategyAuth));
We have only signin task now. It's simple.
signin: function(req, res) {
passport.authenticate('local', function(error, user, info) {
if (error || !user) return res.negotiate(Object.assign(error, info));
return res.ok(user);
})(req, res);
}
This way is more suitable for passport and works great for me.
Say you have this
app.post('/login', urlencodedParser,
// so, user has been to /loginpage and clicked submit.
// /loginpage has a post form that goes to "/login".
// hence you arrive here.
passport.authenticate('my-simple-login-strategy', {
failureRedirect: '/loginagain'
}),
function(req, res) {
console.log("you are in ............")
res.redirect('/stuff');
});
Note that the .authenticate has an explicit tag.
The tags is 'my-simple-login-strategy'
That means you have this ...
passport.use(
'my-simple-login-strategy',
// !!!!!!!!!!!!!note!!!!!!!!!!, the DEFAULT there (if you have nothing)
// is 'local'. A good example of defaults being silly :/
new Strategy(
STRAT_CONFIG,
function(email, password, cb) {
// must return cb(null, false) or cb(null, the_user_struct) or cb(err)
db.findUserByEmailPass(email, password, function(err, userFoundByDB) {
if (err) { return cb(err); }
if (!userFoundByDB) { return cb(null, false); }
console.log('... ' + JSON.stringify(userFoundByDB) )
return cb(null, userFoundByDB)
})
}
)
)
!!! !!! NOTE THAT 'local' IS JUST THE DEFAULT TAG NAME !!! !!!
In passport.use, we always put in an explicit tag. It is much clearer if you do so. Put in an explicit tag in the strategy and in the app.post when you use the strategy.
So that's my-simple-login-strategy.
What is the actual db.findUserByEmailPass sql function?
We'll come back to that!
So we have my-simple-login-strategy
Next ...... we need my-simple-createaccount-strategy
Note that we are still sneakily using passport.authenticate:
So:
the strategy my-simple-createaccount-strategy will actually make an account.
However .............
you should still return a struct.
Note that my-simple-login-strategy has to return a struct.
So, my-simple-createaccount-strategy also has to return a struct - in exactly the same way.
app.post('/createaccount', urlencodedParser,
// so, user has been to /createanaccountform and clicked submit,
// that sends a post to /createaccount. So we are here:
passport.authenticate('my-simple-createaccount-strategy', {
failureRedirect: '/loginagain'
}),
function(req, res) {
console.log("you are in ............")
res.redirect('/stuff');
});
And here's the strategy ..........
passport.use(
'my-simple-createaccount-strategy',
new Strategy(
STRAT_CONFIG,
function(email, password, cb) {
// return cb(null, false), or cb(null, the_user_struct) or cb(err)
db.simpleCreate(email, password, function(err, trueOrFalse) {
if (err) { return cb(err); }
if (!trueOrFalse) { return cb(null, false); }
return cb(null, trueOrFalse)
})
}
)
)
The strategy is pretty much the same. But the db call is different.
So now let's look at the db calls.
Let's look at the db calls!
The ordinary db call for the ordinary strategy is going to look like this:
exports.findUserByEmailPass = function(email, password, cb) {
// return the struct or false via the callback
dc.query(
'select * from users where email = ? and password = ?',
[email, password],
(error, users, fields) => {
if (error) { throw error } // or something like cb(new Error('blah'));
cb(null, (users.length == 1) ? users[0] : false)
})
}
So that's exports.findUserByEmailPass, which is used by my-simple-login-strategy.
But what about exports.simpleCreate for my-simple-createaccount-strategy?
A simple toy version would
check if the username exists already - return false at this point if it does exist already, then
create it, and then
actually just return the record again.
Recall that (3) is just like in the ordinary "find" call.
Remember ... the strategy my-simple-createaccount-strategy will actually make an account. But you should still return a struct in the same way as your ordinary authenticate strategy, my-simple-login-strategy.
So exports.simpleCreate is a simple chain of three calls:
exports.simpleCreate = function(email, password, cb) {
// check if exists; insert; re-select and return it
dc.query(
'select * from users where email = ?', [email],
(error, users, fields) => {
if (error) { throw error } // or something like cb(new Error('blah'));
if (users.length > 0) {
return cb(null, false)
}
else {
return partTwo(email, password, cb)
}
})
}
partTwo = function(email, password, cb) {
dc.query(
'insert into users (email, password) values (?, ?)', [email, password],
(error, users, fields) => {
if (error) { throw error } // or something like cb(new Error('blah'));
partThree(email, password, cb)
})
}
partThree = function(email, password, cb) {
dc.query(
'select * from users where email = ? and password = ?', [email, password],
(error, users, fields) => {
if (error) { throw error } // or something like cb(new Error('blah'));
cb(null, (users.length == 1) ? users[0] : false)
})
}
And that all works.
But note that
passport has nothing to do with account creation!
In fact, you do not have to use a strategy at all.
In app.post('/createaccount' you can, if you wish, do nothing with passport.authenticate ... don't even mention it in the code. Don't use authenticate at all. Just go ahead and do the sql process of inserting a new user, right there in app.post.
However, if you "trickily" use a passport strategy - my-simple-createaccount-strategy in the example - you have the bonus that the user is then immediately logged-in with a session and everything works in the same pattern as the login post. Cool.
Here is what worked for me, the solution is based on a mongoose based odm, the first part is the passport related part, I also attached the user part from odm to who how the encryption of the password is done.
If I understood your question, you want the user to type either his email or password. In this case modify the search to try both, that is, match the provided user identifier (in your call to findOne(...) with either the username or password.
Note that I use bcrypt to avoid storing clear passwords, that's why there is a customized compare method for testing passwords. Also note 'hints' of using google auth as well, My system enabled both, if it is relevant, please lemme know and I can add the required code.
------------ Auth part (just relevant snippets) -----------

This has actually nothing to do with passport and is pretty simple, assuming you are using body-parser. Make sure you have an input field in your form with the attribute name="name" where you register the user's name like:
<div class="form-group">
<label for="signup-name">Name</label>
<input type="text" placeholder="Name" name="name">
</div>
In your routing, you can access this field with req.body.name:
passport.use('local-signup', new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
//are there other options?
//emailField did not seem to do anything
passReqToCallback: true
},
function(req, email, password, done) {
//check if email not already in database
//create new user using "email" and "password"
//I want an additional parameter here "name"
user.email = email;
user.password = password; // Do some hashing before storing
user.name = req.body.name;
}));
So you can add as many form input fields as you want, access them by the value of the name attribute. A Second example would be:
<input type="text" placeholder="City" name="city">
<input type="text" placeholder="Country" name="country">
// Access them by
user.city = req.body.city;
user.country = req.body.country;
UserModel.find({email: req.body.email}, function(err, user){
if(err){
res.redirect('/your sign up page');
} else {
if(user.length > 0){
res.redirect('/again your sign up page');
} else{
//YOUR REGISTRATION CODES HERE
}
}
})
In strategy options set the passReqToCallback:true and then add req as parameter into your callback function. Finally, read the extra information from req.body object for example req.body.firstName
const signup = new Strategy({
usernameField: "username",
passwordField: "password",
passReqToCallback:true
}, async (req, username, password, done) => {
try {
const user = User.create();
user.username = username;
user.password = password;
user.firstName = req.body.firstName;
user.lastName = req.body.lastName
await user.save()
return done(null, user);
} catch (error) {
return done(error, null);
}
});
I need to write commonplace code to check a Current User Password value submitted via form to see if it matches the existing password in the database, and if so, update the password to a New Password value that was submitted via the same form.
Yet, I can't find any good examples of how to do this using Passport.js. Can anyone advise as to how I can do this in my Users controller down below, if there are any helper functions provided by passport that I should use for this, and how I do this with hashed and salted passwords?
Here is my code:
// Form Submitted
req.body = {
_id: '5294198b7b35ad2794000001',
email: 'testusera1#abc.net',
name: 'John Smith',
provider: 'local',
username: 'ab123',
current_password: 'currentpassword',
new_password: 'newpassword'
}
// Route
app.put('/users/me', users.update);
// Controller
var mongoose = require('mongoose'),
User = mongoose.model('User'),
_ = require('underscore'),
passport = require('passport'),
LocalStrategy = require('passport-local').Strategy;
exports.update = function(req, res) {
var user = req.user
user = _.extend(user, req.body);
user.save(function(err) {
if(err) { console.log(err) };
res.jsonp(user);
});
};
// Passport Config File
module.exports = function(passport) {
//Serialize sessions
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
User.findOne({
_id: id
}, function(err, user) {
done(err, user);
});
});
//Use local strategy
passport.use(new LocalStrategy({
usernameField: 'email',
passwordField: 'password'
},
function(email, password, done) {
User.findOne({
email: email
}, function(err, user) {
if (err) {
return done(err);
}
if (!user) {
return done(null, false, {
message: 'Unknown user'
});
}
if (!user.authenticate(password)) {
return done(null, false, {
message: 'Invalid password'
});
}
return done(null, user);
});
}
));
};
hashed and salted password
full example on github
// Bcrypt middleware

var user = this;

if(err) return next(err);
bcrypt.hash(user.password, salt, function(err, hash) {
if(err) return next(err);
user.password = hash;
next();
});
});
});
// Password verification
