Passport.js-req.isAuthenticated不是一个函数

Question

我是node、express和node的新手，我正在使用passport.js构建身份验证功能；checkNotAuthenticated"；以检查用户是否未通过身份验证，但我收到了以下错误："；TypeError:req.isAuthenticated不是一个函数">

这里可能有什么问题？

我的路线：

const express = require('express')
const router = express.Router()
const bcrypt = require('bcrypt')
const passport = require('passport')
const flash = require('express-flash')
const session = require('express-session')
const methodOverride = require('method-override')
const User = require('../models/user.model')
const initializePassport = require('../passport-config')
initializePassport(passport)
const app = express()
app.use(flash())
app.use(session({
secret: process.env.SESSION_SECRET,
resave: false,
saveUninitialized: false
}))
app.use(passport.initialize())
app.use(passport.session())
app.use(methodOverride('_method'))
/* Middleware function to check if user is authenticated */
function checkNotAuthenticated(req, res, next) {
if (req.isAuthenticated()) {
return res.redirect('/')
}
next()
}
/* ------- Routes ------- */
/* Create new user */
router.post('/register', checkNotAuthenticated, async (req, res) => {
/* Check if the email isn't already taken */
const emailIsTaken = await User.findOne({email: req.body.email})
if (emailIsTaken) return res.status(500).send('Email already used')
try {
const hashedPassword = await bcrypt.hash(req.body.password, 10)
const user = new User({
name: req.body.name,
password: hashedPassword,
email: req.body.email,
title: req.body.title,
about: req.body.about
})
user.save()
res.send('Success - User created')
} catch (err) {
res.status(500).send(err)
}
})
/* Login user */
router.post('/login', checkNotAuthenticated, passport.authenticate('local', {
successRedirect: '/',
failureRedirect: '/login',
failureFlash: true
}))
/* Logout */
router.delete('/logout', (req, res) => {
req.logOut()
res.redirect('/login')
})
module.exports = router

passport-config.js:

const User = require('./models/user.model')
const LocalStrategy = require('passport-local').Strategy
const bcrypt = require('bcrypt')
function initializePassport(passport) {
const authenticateUser = async done => {
/* Check if there's a user account created with that email */
const userFound = await User.findOne({email: req.body.email})
if (!userFound) return done(null, false, {message: 'Cannot find user with that email'})

/* Validate password */
try {
const checkPassword = await bcrypt.compare(req.body.password, userFound.password)
if (checkPassword) {
return done(null, userFound)
} else {
return done(null, false, {message: 'Incorrect password'})
}

} catch (err) {
return done(err)

}
}
passport.use(new LocalStrategy( { usernameField: 'email' }, authenticateUser) )
passport.serializeUser(done => { done(null, userFound.id) })
passport.deserializeUser(done => { done(null, userFound) })
}
module.exports = initializePassport

完全错误：

Answer 1

function checkNotAuthenticated(req, res, next) {
if (req.isAuthenticated()) {
return res.redirect('/')
}
next()
}

将这个中间件函数放在之前的脚本底部

module.exports = router;
