Node.js module.exports passport已認證到路由

Question

我想分開文件中的每組路由。我需要在大多數路由中使用isAuthenticated來限制訪問。當我把所有路線放在同一個文件中時，它就起作用了。

當我auth.js和order.js使用module.exports = isAuthenticated我用var auth = require('auth.js');我會得到一個錯誤「isAuthenticated沒有定義」當我去http://localhost:3000/order在auth.js只是按預期工作定義的路由。

我使用Express.js中間件「護照本地策略」（隨後從​​tutsplus教程和here下載的GitHub庫）。

我的項目結構：

bin/www 
models/auth/init.js 
models/auth/user.js 
models/auth/signup.js 
models/auth/login.js 
models/order.js 
views/error.pug 
views/index.pug 
views/home.pug 
views/layout.pug 
views/order.pug 
views/register.pug 
routes/order.js 
routes/auth.js 
public/stylesheets/style.css 
app.js 
db.js 

./routes/auth.js：

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


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 = isAuthenticated; 

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; 
} 

./routes/order.js：

var express = require('express'); 
var router = express.Router(); 
var order = require('../models/order'); 

var auth = require('./auth.js'); 



module.exports = function(passport){ 

    router.get('/order', isAuthenticated, function(req, res){ 
    res.render('order'); 

    }); 

    router.post('/order', isAuthenticated, function(req, res) 
    { 
     var testorder = new order({ 
      orderid: '52363', 
      productname: 'it works', 
      quantity: 1337 
     }); 
     testorder.save(function (err) { 
      if (err) {console.log(err.stack);}  
      console.log('saving done...'); 
     }); 

      res.render('order', { product: req.body.productname }); 
    }); 

};

嘗試auth.isAuntheticated（）， 它應該這樣工作。
