如何使用Passport.js和express.js

我想第一次使用Passport.js的功能，但是当我尝试登录时没有任何反应。有人可以帮我弄清楚我错过了什么或者我的代码出了什么问题？这是我的代码，它不起作用，我坚持使用Passport-local功能以用户名&密码登录。如何使用Passport.js和express.js

var express = require('express'); 
var http = require('http'); 
var app = express(); 
var port = 1535; 
var server = http.createServer(app) 
var io = require('socket.io').listen(server); 
var mongoose = require('mongoose'); 
var passport = require('passport'); 
var LocalStrategy = require('passport-local').Strategy; 
var flash = require('connect-flash'); 

//Connection to the MongoDB ODM. 
var db = mongoose.createConnection('localhost', 'test'); 
db.on('error', console.error.bind(console, 'connection error:')); 
db.once('open', function callback() { 
console.log('Connected to MongoDB'); 
}); 

//User schema. 
var userSchema = mongoose.Schema({ 
username: String, 
password: String 
}); 

//Check the user password. 
userSchema.methods.validPassword = function (password) { 
if (password === this.password) { 
    return true; 
} else { 
    return false; 
} 
} 

var User = mongoose.model('User', userSchema); 
var user = new User({ username: 'andrew', password: 'secret' }); 
user.save(); 

//Express.js configuration. 
app.configure(function(){ 
app.set('port', process.env.PORT || 1535); 
app.use(express.bodyParser()); 
app.use(express.methodOverride()); 
app.use(express.cookieParser()); 
app.use(express.session({ cookie: { maxAge: 60000 }, secret: 'keyboard cat' })); 
app.use(flash()); 
app.use(passport.initialize()); 
app.use(passport.session()); 
app.use(app.router); 
app.use('/static', express.static(__dirname + '/')); 
}); 

//Check the login form with Passport.js 
passport.serializeUser(function(user, done) { 
done(null, user); 
}); 

passport.deserializeUser(function(obj, done) { 
done(null, obj); 
}); 

passport.use(new LocalStrategy(function(username, password, done) { 
    User.findOne({ username: username }, function(err, user) { 
     if (err) { 
      return done(err); 
     } 
     if (!user) { 
      return done(null, false, { message: 'Incorrect username.' }); 
     } 
     if (!user.validPassword(password)) { 
      console.log('Invalid password...') 
      return done(null, false, { message: 'Incorrect password.' }); 
     } 
     return done(null, user); 
    }); 
} 
)); 

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

//Express.js - launch the server. 
server.listen(app.get('port'), function(){ 
console.log("Express server listening on port" + app.get('port')); 
});

您的passport.serialize返回用户配置文件。这将被JSON.stringified并存储在express.session中。这稍后传递给您的passport.deserialize，它返回字符串而不是解析它并返回用户配置文件对象。

尝试：

done(null, JSON.parse(obj));

你最终可能会具有较大的用户配置文件中结束。那时你可能想要序列化到user.id之类的东西来减少会话存储量。在反序列化过程中，您可以使用ID读取用户配置文件。
