在路由器中调用中间件function

我正在使用Mozilla的客户端会话在我的express.js应用程序上实施会话，我需要一些帮助。 我在我的router.js和app.js中的中间件中有我的post和gest请求，运行时出现这个错误：

ReferenceError：requireLogin没有被定义

//index.js（路由器）

var express = require('express') , router = express.Router() , user = require('../public/js/models/test.js'); router.get('/profile-header', requireLogin, function (req, res, html) { console.log(req.session); res.render('templates/profile-header.jade', { title: 'Default' }) }); router.get('/sign-in', function (req, res, html) { res.render('templates/sign-in.jade', { title: 'Sign In' }) }); router.get('/blog-home', requireLogin, function (req, res, html) { res.render('templates/blog-home.jade', { title: 'Blog' }) }); router.get('/logout', function(req, res) { req.session.reset(); res.redirect('/'); }); router.post('/profile-header', function (req, res, html) { user.login(req.body, function (e, o) { if (o) { //add session req.session.user = o; res.redirect('/profile-header'); } else { res.render('templates/sign-in.jade', { error: 'Invalid email or password.' }); } }); }); module.exports = router; 

//app.js

 var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieParser = require('cookie-parser'); var bodyParser = require('body-parser'); var stylus = require('stylus'); var bcrypt = require('bcrypt'); var should = require('should'); var session = require('client-sessions'); var index = require('./routes/index'); var users = require('./routes/users'); var app = express(); // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'jade'); // uncomment after placing your favicon in /public //app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); function requireLogin (req, res, next) { if (!req.user) { console.log("pd"); res.redirect('/sign-in'); } else { next(); } }; app.use(session({ cookieName: 'session', secret: 'random_string_goes_here', duration: 30 * 60 * 1000, activeDuration: 5 * 60 * 1000, })); app.use(logger('dev')); app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json()); app.use(cookieParser()); app.use(stylus.middleware(path.join(__dirname, 'public'))); app.use(express.static(path.join(__dirname, 'public'))); app.use(function(req, res, next) { res.header("Access-Control-Allow-Origin", "*"); res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept"); next(); }); app.use('/', index); app.use('/users', users); app.use(function(req, res, next) { if (req.session && req.session.user) { user.exist(req.session.username, function (e, o) { if (user) { req.user = user; delete req.user.user_password; // delete the password from the session req.session.user = user; //refresh the session value console.log(req.session); res.locals.user = user; } // finishing processing the middleware and run the route next(); }); } else { next(); } }); // listener app.listen(process.env.PORT || 3000, function () { console.log('Listening on http://localhost:' + (process.env.PORT || 3000)) }) module.exports = app; 

Thx为您的帮助！

问题是requireLogin是在app.js定义的，但是在index.js没有定义。 我build议将requireLogin移动到外部服务中，并在需要时导入/需要：

 // auth.service.js exports.requireLogin = function (req, res, next) { ... }; 

然后在index.js添加这个：

 var Auth = require('./auth.service'); .... router.get('/profile-header', Auth.requireLogin, function (req, res, html) { console.log(req.session); res.render('templates/profile-header.jade', { title: 'Default' }) });
