密码哈希bcrypt比较失败？

如何解决密码哈希bcrypt比较失败？

我正在遵循freeCodeCamp的Youtube教程，但是我的代码无法比较我的哈希密码和用户输入的密码。

Authencation.js代码

const { User } = require('../models')
const jwt = require('jsonwebtoken')
const config = require('../config/config')

function jwtSignUser (user) {
  const ONE_WEEK = 60 * 60 * 24 * 7
  return jwt.sign(user,config.authentication.jwtSecret,{
    expiresIn: ONE_WEEK
  })
}

module.exports = {
  async register (req,res) {
    try {
      const user = await User.create(req.body)
      const userjson = user.toJSON()
      res.send({
        user: userjson,token: jwtSignUser(userjson)
      })
    } catch (err) {
      console.log(err)
      res.status(400).send({
        error: 'This email account is already in use.'
      })
    }
  },async login (req,res) {
    try {
      const { email,password } = req.body
      const user = await User.findOne({
        where: {
          email: email
        }
      })
      console.log(user)
      if (!user) {
        return res.status(403).send({
          error: 'The email information was incorrect'
        })
      }

      const isPasswordValid = await user.comparePassword(password)
      console.log(isPasswordValid)
      if (!isPasswordValid) {
        return res.status(403).send({
          error: 'The password information was incorrect'
        })
      }

      const userjson = user.toJSON()
      res.send({
        user: userjson,token: jwtSignUser(userjson)
      })
    } catch (err) {
      console.log(err)
      res.status(500).send({
        error: 'An error has occured trying to log in'
      })
    }
  }
}

在这里user.comparePassword（password）是需要将密码与存储的密码和用户输入的密码进行比较的功能

哈希和存储是通过User.js完成的

const Promise = require('bluebird')
const bcrypt = Promise.promisifyAll(require('bcrypt'))

function hashPassword (user,options) {
  const SALT_FACTOR = 8

  if (!user.changed('password')) {
    return
  }

  return bcrypt
    .genSalt(SALT_FACTOR)
    .then(salt => bcrypt.hash(user.password,salt,null))
    .then(hash => {
      user.setDataValue('password',hash)
    })
}

module.exports = (sequelize,DataTypes) => {
  const User = sequelize.define('User',{
    email: {
      type: DataTypes.STRING,unique: true
    },password: DataTypes.STRING
  },{
    hooks: {
      beforeCreate: hashPassword,beforeUpdate: hashPassword,beforeSave: hashPassword
    }
  })

  User.prototype.comparePassword = function (password) {
    return bcrypt.compare(password,this.password)
  }
  return User
}
