Я пытаюсь реализовать простую страницу входа и регистрации пользователя для моего приложения.
Страница регистрации работает, и все правильно хранится в mongodb.Однако, когда я пытаюсь войти в систему, это, кажется, не работает.Предполагается, что перенаправить на мою корневую страницу, но это не будет делать.Он всегда перенаправляет обратно в / users / login
Я просматривал учебное пособие онлайн, поэтому я не понимаю, почему это не работает.Вот соответствующие файлы.
user.js file
const express = require('express');
const router = express.Router();
const bcrypt = require('bcryptjs');
const passport = require('passport');
let User = require('../models/user');
// Load register form
router.get('/register', function(req, res) {
res.render('register', {
title : 'Register',
errors : req.flash('success')
});
});
// Submit register form
router.post('/register', function(req, res) {
// Get the fields from the form
const firstname = req.body.firstname;
const lastname = req.body.lastname;
const email = req.body.email;
const pass = req.body.pass;
const pass2 = req.body.pass2;
// Verify body is not empty.
req.checkBody('firstname', 'First name is required').notEmpty();
req.checkBody('lastname', 'Last name is required').notEmpty();
req.checkBody('email', 'Email is required').notEmpty();
req.checkBody('email', 'Email is not valid').isEmail();
req.checkBody('pass', 'Password is required').notEmpty();
req.checkBody('pass2', 'Passwords do not match.').equals(req.body.pass);
// Check for errors
let errors = req.validationErrors();
if (errors) {
res.render('register', {
errors:errors
});
} else {
// Create new user object
let newUser = new User({
firstname:firstname,
lastname:lastname,
email:email,
pass:pass
});
// Hash the password for security.
bcrypt.genSalt(10, function(err, salt){
bcrypt.hash(newUser.pass, salt, function(err, hash) {

newUser.pass = hash;
