无法将用户序列化为会话

Question

可以注册，并提示无效的用户名/密码，但在用户成功登录时会因序列化用户错误而中断。我似乎无法弄清楚我做错了什么。我试图找出如何实现multer和上传个人资料图片，它打破了x（

路由/ user.js的

var express = require('express');
var router = express.Router();
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;

var User = require('../models/user');

// Register
router.get('/register', function(req, res){
    res.render('register');
});

// Login
router.get('/login', function(req, res){
    res.render('login');
});

// Register User
router.post('/register', function(req, res){
    var firstName = req.body.firstName;
    var middleName = req.body.middleName;
    var lastName = req.body.lastName;

    var email = req.body.email;
    var phoneNumber = req.body.phoneNumber;
    var password = req.body.password;
    var password2 = req.body.password2;

    // Validation
    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('password', 'Password is required').notEmpty();
    req.checkBody('password2', 'Passwords do not match').equals(req.body.password);

    var errors = req.validationErrors();

    if(errors){
        res.render('register',{
            errors:errors
        });
    } else {
        var newUser = new User({
            firstName: firstName,
            middleName: middleName,
            lastName: lastName,
            email:email,
            phoneNumber: phoneNumber,
            password: password
        });

        User.createUser(newUser, function(err, user){
            if(err) throw err;
            console.log(user);
        });

        req.flash('success_msg', 'You are registered and can now login');

        res.redirect('/users/login');
    }
});

passport.use(new LocalStrategy(
  function(email, password, done) {
   User.getUserByEmail(email, function(err, user){
    if(err) throw err;
    if(!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 {
            return done(null, false, {message: 'Invalid password'});
        }
    });
   });
  }));

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  User.getUserById(id, function(err, user) {
    done(err, user);
  });
});

router.post('/login',
  passport.authenticate('local', {successRedirect:'/', failureRedirect:'/users/login',failureFlash: true}),
  function(req, res) {
    res.redirect('/');
  });

router.get('/logout', function(req, res){
    req.logout();

    req.flash('success_msg', 'You are logged out');

    res.redirect('/users/login');
});

module.exports = router;

模型/ user.js的

var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');

// User Schema
var UserSchema = mongoose.Schema({
    id:{
        type: String,
        index:true
    },
    email: {
        type: String,
        index:true
    },
    password: {
        type: String
    },
    firstName: {
        type: String
    },
    middleName: {
        type: String
    },
    lastName: {
        type: String
    },
    phoneNumber: {
        type: String,
        index:true
    }
});

var User = module.exports = mongoose.model('User', UserSchema);

module.exports.createUser = function(newUser, callback){
    bcrypt.genSalt(10, function(err, salt) {
        bcrypt.hash(newUser.password, salt, function(err, hash) {
            newUser.password = hash;
            newUser.save(callback);
