Node.js Question
Node JS Passport - 400 Bad request for register
I try to implement a register on my web app, using Node JS and Passport.js for local authentication, but I have this error when I Post the request on Insomnia (Like Postman) :
Bad Request
I don't understand because I have follow a tutorial that I find on Google to do this.
Here is the route (auth.js):
const passport = require('passport');
const router = require('express').Router();
//const UserController = require('../controller/UserController');
router
// login
.post("/login", passport.authenticate("local", function(req, res, next) {
console.log(req);
}))
// logout
.get('/logout', (req, res, next) => {
req.session.destroy((err) => {
res.redirect('/login')
})
})
// signup
.post("/signup", passport.authenticate("local-register"), (req, res) => {
var userInfo = req.body;
})
module.exports = router;
Here is Passport.js file :
const bcrypt = require('bcrypt-nodejs');
const db = require("./queries");
const passport = require('passport');
const LocalStrategy = require("passport-local").Strategy
passport.use(new LocalStrategy(authenticate))
passport.use("local-register", new LocalStrategy({passReqToCallback: false}, register))
function authenticate(email, password, done) {
db.one('select * from users where email = $1', email)
.then((user) => {
if(!user || !bcrypt.compareSync(password, user.password)) {
return done(null, false, {message: "invalid user and password combination"});
}
done(null, user)
}, done);
}
function register(email, password, done) {
db.one('select * from users where email = $1', email)
.then((user) => {
if(user) {
return done(null, false, {message: "An user with this address have already been created."});
}
const newUser = {
email: email,
password: bcrypt.hashSync(password),
};
db.none('insert into users(email, password) values($1, $2)', [newUser.email, newUser.password])
.then((ids) => {
newUser.id = ids[0]
done(null, newUser)
})
})
}
passport.serializeUser(function(user, done) {
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
db.one('select * from users where id = $1', id)
.then((user) => {
done(null, user)
}, done);
});
I'm using Postgresql as DB for this project, with pg-promise package.
And this is the app.js file :
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var session = require('express-session');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var passport = require('passport')
require('./passport');
var index = require('./routes/index');
var usersRoutes = require('./routes/users');
var authRoutes = require('./routes/auth');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(passport.initialize())
app.use(passport.session())
app.use('/', index);
app.use(usersRoutes);
app.use(authRoutes);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
Doest anyone know why I have this response ? I try with a post method using email and password on Insomnia,
Thank you !

By default, LocalStrategy expects to find credentials in parameters named username and password. (passport-local on Github).
So you need to edit this line and set usernameField to email
passport.use("local-register", new LocalStrategy({passReqToCallback: false, usernameField: 'email'}, register))
