Node.js 错误：bcrypt需要数据和散列参数。MongoDB设置不正确

我正试图用Express和MongoDB设置Passport。目前，我可以在数据库中注册用户。但每当我尝试登录时，我都会收到一个错误，说明需要数据和散列参数。现在我的Server.js文件如下

const mongoose = require('mongoose');
const User = require('./models/users')

     const initializePassport = require('./passport-config')
      initializePassport(
        passport,
        email => User.find({email: email}),
        id => User.find({id: id})
      )


      app.post('/register', checkNotAuthenticated, async (req, res) => {
        try {
          const hashedPassword = await bcrypt.hash(req.body.password, 10)
          const newUser = new User({
            id: Date.now().toString(),
            name: req.body.name,
            email: req.body.email,
            password: hashedPassword
          })
          res.redirect('/login')
          console.log(newUser)
        } catch {
          res.redirect('/register')
        }

    And my Passport-Config.js file like this `

    const LocalStrategy = require('passport-local').Strategy
    const bcrypt = require('bcrypt');
    const User = require('./models/users')

    function initialize(passport, getUserByEmail, getUserById) {
      const authenticateUser = async (email, password, done) => {
        const user = getUserByEmail(email)
        if (user === null) {
          return done(null, false, { message: 'No user with that email' })

        }

        try {
          if (await bcrypt.compare(password, user.password)) {
            return done(null, user)
          } else {
            return done(null, false, { message: 'Password incorrect' })
          }
        } catch (e) {
          return done(e)
        }
      }

      passport.use(new LocalStrategy({ usernameField: 'email' }, authenticateUser))
      passport.serializeUser((user, done) => done(null, user.id))
      passport.deserializeUser((id, done) => {
        return done(null, User.findById({user: id}))
      })
    }

    `

我已经使用console.log（）语句进行了一些调查（并不自豪），但我想我已经找到了问题所在。如果我们在此处添加第一个控制台日志语句：

  app.post('/register', checkNotAuthenticated, async (req, res) => {
    try {
      console.log("BCRYPT COMPARE RUNS HERE")
      const hashedPassword = await bcrypt.hash(req.body.password, 10)
      const newUser = new User({
        id: Date.now().toString(),
        name: req.body.name,
        email: req.body.email,
        password: hashedPassword
      })
      res.redirect('/login')
      console.log(newUser)
    } catch {
      res.redirect('/register')
    }

第二个是：

 const initializePassport = require('./passport-config')
  initializePassport(
    passport,
    email => User.find({email: email}).then((result) => { console.log("USER DATA EXTRACTED HERE") }).catch((err) => { console.log(err) }),
    id => User.find({id: id})
  )

下次单击login时，您应该会看到如下输出：

Listening on port 3000
BCRYPT COMPARE HAPPENING
Error: data and hash arguments required
...
...
...
USER DATA EXTRACTED HERE

请注意，bcrypt.compare是在我们实际能够从数据库中获取用户信息之前运行的？这意味着该函数中的所有参数都为null，这就是返回该错误的原因。现在，我不是JS专家，但这可以通过添加一条等待语句来解决：

   function initialize(passport, getUserByEmail, getUserById) {
      const authenticateUser = async (email, password, done) => {
        const user = await getUserByEmail(email)
        if (user === null) {
          return done(null, false, { message: 'No user with that email' })

        }

这确保在脚本中移动之前从DB查询用户信息。

Ahh，在尝试将本地JSON对象上的用户转换为mongodb集合时，我也面临相同的错误。。。我认为这与bcrypt比较方法有关，但不太确定。很高兴知道有人和我面临同样的问题！
