passport.authenticate 不是函数

Question

您好，我是 NodeJs 的新手，我一直在按照本教程 http://code.tutsplus.com/tutorials/authenticating-nodejs-applications-with-passport--cms-21619 创建一个带有身份验证的应用程序。我尝试遵循教程中的所有结构和代码（代码在 github https://github.com/tutsplus/passport-mongo 上）但是当我在浏览器中打开我的应用程序时我得到错误这个错误

TypeError: passport.authenticate is not a function at module.exports (C:\myApp\routes\index.js:24:34)

这是我的index.js路由文件

var express = require('express');
var router = express.Router();
var passport = require('passport');

var isAuthenticated = function (req, res, next) {
  // if user is authenticated in the session, call the next() to call the next request handler
  // Passport adds this method to request object. A middleware is allowed to add properties to
  // request and response objects
  if (req.isAuthenticated())
    return next();
  // if the user is not authenticated then redirect him to the login page
  res.redirect('/');
}

module.exports = function(passport){

  /* GET login page. */
  router.get('/', function(req, res) {
    // Display the Login page with any flash message, if any
    res.render('index', { message: req.flash('message') });
  });

  /* Handle Login POST */
  router.post('/login', passport.authenticate('login', {
    successRedirect: '/home',
    failureRedirect: '/',
    failureFlash : true
  }));

  /* GET Registration Page */
  router.get('/signup', function(req, res){
    res.render('register',{message: req.flash('message')});
  });

  /* Handle Registration POST */
  router.post('/signup', passport.authenticate('signup', {
    successRedirect: '/home',
    failureRedirect: '/signup',
    failureFlash : true
  }));

  /* GET Home Page */
  router.get('/home', isAuthenticated, function(req, res){
    res.render('home', { user: req.user });
  });

  /* Handle Logout */
  router.get('/signout', function(req, res) {
    req.logout();
    res.redirect('/');
  });

  return router;
}

可能是问题所在，也许某些版本的 express 更改了路由，但我无法弄清楚问题出在哪里。你能帮助我吗？

Answer 1

你刚刚把括号放错了地方。应该是

router.post('/login', passport.authenticate('login'), {
    successRedirect: '/home',
    failureRedirect: '/',
    failureFlash : true
  });

我遇到了同样的问题。看看app.js。必须有：

var routes = require('./routes/index')(passport);

passport.authenticate 不是函数

passport.authenticate is not a function

javascript

node.js

passport.js
