无法使用Express和MongoDB/Mongoose设置Passport - 示例代码？

Question

我是新来的Node.js.尝试设置用户帐户创建并使用Passport登录。

我选择了护照，因为它的受欢迎程度，但我似乎无法拼凑一个基于Passport网站上的文档工作身份验证过程。

有没有人知道这个设置的教程？最好在那里你可以下载源代码。

我会分享我的app.js文件，也许这会揭示什么是缺乏。

var express = require('express') 
    , routes = require('./routes') 
    , home = require('./routes/home') 
    , user = require('./routes/user') 
    , http = require('http') 
    , path = require('path') 
    , passport = require('passport') 
    , LocalStrategy = require('passport-local').Strategy 
    , flash = require('connect-flash'); 


var app = express(); 

app.configure(function(){ 
    app.set('port', process.env.PORT || 3000); 
    app.set('views', __dirname + '/views'); 
    app.set('view engine', 'jade'); 
    app.use(express.favicon()); 
    app.use(express.logger('dev')); 
    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(express.static(path.join(__dirname, 'public'))); 
}); 

app.configure('development', function(){ 
    app.use(express.errorHandler()); 
}); 

passport.serializeUser(function(user, done) { 
    done(null, user); 
}); 

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

passport.use(new LocalStrategy({ 
    usernameField: 'email', 
    passwordField: 'password' 
    }, 
    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)) { 
     return done(null, false, { message: 'Incorrect password.' }); 
     } 
     return done(null, user); 
    }); 
    } 
)); 

app.get('/', routes.index); 
app.post('/login', 
    passport.authenticate('local', { 
    successRedirect: '/home', 
    failureRedirect: '/', 
    failureFlash: true 
    }) 
); 
app.get('/home', home.dashboard); 
app.get('/users', user.list); 

http.createServer(app).listen(app.get('port'), function(){ 
    console.log("Express server listening on port " + app.get('port')); 
}); 

注：此代码只是试图登录时，我返回到根页面我意识到，我并不在这一点上有任何实际的用户帐户，但我想至少获得成功用假用户登录。我错过了什么？

Answer 2

有一个使用passport-local和Express作为passport-local source的一部分的示例。将passport.authenticatepassport.authenticate调用的failureRedirect设置为login页面并将必要的代码添加到登录视图模板以显示Flash消息可能会有所帮助，请参阅链接的源代码。如果您需要更多帮助，请查看其他护照模块的来源。

看起来问题可能在LocalStrategy的回调中。 User模型似乎并未被要求。
