node.js – 表示cookie返回undefined

我正在尝试在express.js上设置cookie,但它返回undefined.
我搜索了很多网页,并在app.use(app.router)上面放了express.cookieParser()
但它仍然无法返回正确的价值.

app.js

app.configure(function(){
   var redisStore = require('connect-redis')(express);
    app.use(express.logger());
    app.set('view options',{ layout: false });
    app.set('views',__dirname + '/views');
    app.set('view ENGIne','jade');
    app.use(express.bodyParser({uploadDir: './uploads/tmp'}));
    app.use(express.methodOverride());
    app.use(express.cookieParser());
    app.use(express.session({ secret: "william",store: new redisStore }));
//Initialize Passport!  Also use passport.session() middleware,to support
//persistent login sessions (recommended).
    app.use(passport.initialize());
    app.use(passport.session());
    //app.router should be after passportjs
    app.use(app.router);
    app.use(express.compiler({ src: __dirname + '/public',enable: ['less']}));
    app.use(express.static(path.join(__dirname,'public')));
});

app.get('/',function(req,res) {
    res.cookie('cart','test',{maxAge: 900000,httpOnly: truE})
});

app.get('/test',res) {
    res.send('TESTCookie: ' + req.cookies.cart);
});

结果：

TESTCookie: undefined

app.get('/',httpOnly: truE});
    res.send('check your cookies. One should be in there Now');
});
