护照-本地猫鼬中缺少密码错误

Question

我正在从Coursera学习Node js课程，同时在学习使用通行证的用户身份验证时，我遇到了这个错误。我完全按照课程中所说的去做，但是我遇到了这个错误！

我了解该课程的某些内容已被弃用，但是如何解决此错误？

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var passportLocalMongoose = require('passport-local-mongoose');

var User = new Schema({
    // username: { // auto added by passport
    //     type: String,
    //     required: true,
    //     unique: true,
    // },
    // password: {
    //     type: String,
    //     required: true,
    // },
    admin: {
        type: Boolean,
        default: false,
    }
});

User.plugin(passportLocalMongoose);

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

我的身份验证

var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var User = require('./models/user');

exports.local = passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

router.post('/signup', (req, res, next) => {
  // User.findOne({ username: req.body.username })
  User.register(new User({ username: req.body.username }, req.body.password, (err, user) => {
    if (err) {
      console.log(err);
      res.statusCode = 500;
      res.setHeader('Content-Type', 'application/json');
      res.json({ err: err });
    } else {
      console.log(user);
      passport.authenticate('local')(req, res, () => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json({ success: true, status: 'Registration Successful' });
      });
    }
  })); // passport-local-mongoose
});

我的app.js

app.use(passport.initialize());
app.use(passport.session());

app.use('/', indexRouter);
app.use('/users', usersRouter);

function auth(req, res, next) {
  if (!req.user) { // auto loaded by passport
    var err = new Error('You are not authenticated!!!');
    err.status = 401;
    return next(err);
  } else {
    next();
  }
}

app.use(auth);

解决了！ 这是Router中的愚蠢错字！我没有关闭用户对象，然后将密码作为参数传递，而是忘记了关闭用户对象！
