如何在node.js中使用Passport访问序列化用户

我已经能够使用Passport进行身份validation,但是我不知道如何访问序列化的用户。 我已经读了几个地方,访问它的方式是与req.user,但是当我尝试与GET /你好,它说,用户是未定义的…

这是我的app.js

var express = require('express'); var routes = require('./routes'); var user = require('./routes/user'); var authentication = require('./routes/authentication'); var content = require('./routes/content'); var posts = require('./routes/post.js'); var upload = require('./routes/upload.js'); var media = require('./routes/media.js'); var http = require('http'); var path = require('path'); var passport = require('passport'); var LocalStrategy = require('passport-local').Strategy; var mongoose = require('mongoose'); var mongoConnectionString = 'mongodb://localhost/judgmental'; var User = require('./models/user.js'); mongoose.connect(mongoConnectionString, function(error) { if (error) { throw error; } console.log('Successfully connected to MongoDB'); }); var app = express(); // all environments app.set('port', process.env.PORT || 3001); app.set('views', __dirname + '/views'); app.set('view engine', 'jade'); app.set('upload_dir', __dirname + '/uploads/posts/'); app.use(express.favicon()); app.use(express.logger('dev')); app.use(express.bodyParser({uploadDir:'./uploads/temp'})); app.use(express.methodOverride()); app.use(express.static(path.join(__dirname, 'public'))); app.use(express.cookieParser('keyboard cat')); app.use(express.cookieSession({secret:'keyboard cat', maxAge: 1000})); app.use(express.session({ secret: 'keyboard cat' })); app.use(passport.initialize()); app.use(passport.session()); app.use(app.router); // development only if ('development' == app.get('env')) { app.use(express.errorHandler()); } passport.use(new LocalStrategy( function(username, password, done) { var query = username.indexOf("@") !== -1 ? {email: username} : {username: username}; User.findOne(query, function (err, user) { if (err) { return done(err); } if (!user) { return done(null, false, { message: 'Incorrect username.' }); } user.authenticate(password, function(error, user){ if (error) { return done(error); } if (!user) { return done(null, false, { message: 'Incorrect password.' }); } return done(null, user); }); }); } )); // routes // Users app.get('/', routes.index); app.get('/users', user.list); app.get('/content', content.show); // Posts app.get('/post', posts.single); app.get('/post/test/:id', posts.test); app.get('/posts', posts.list); app.post('/post/submitPost', posts.submitPost); app.get('/post/upload', posts.uploadDefault) // Upload app.post('/upload/upload-file', upload.upload); // Image handler app.get('/media/:id', media.getImage); // Authentication app.post('/signUp', authentication.signUp); app.post('/signIn', authentication.signIn); app.get('/hello', function(req, res) { res.render('index.jade', { id: req.user.id }); }); passport.serializeUser(function(user, done) { console.log("serializeUser"); done(null, user.id); }); passport.deserializeUser(function(id, done) { console.log("deserializeUser"); User.findById(id, function(err, user) { done(err, user); }); }); http.createServer(app).listen(app.get('port'), function(){ console.log('Express server listening on port ' + app.get('port')); }); 

我知道用户是序列化的,因为控制台在我进行身份validation时logging了“serializeUser”。 有人知道如何获得序列化的用户在我的GET /你好?
