打不开程序显示服务器未启动,node启动服务器以后显示正常运行浏览器却打不开。...

我也不说啥了，直接上代码吧！

var express = require('express'),

//session = require('express-session'),

mongoose = require('mongoose'),

router = require('./lib/router'),

bodyParser = require('body-parser'),

multer = require('multer'),

User = require('./lib/models/user'),

app = express();

app.use(bodyParser.urlencoded({ extended: false }));

app.use(bodyParser.json()); // for parsing application/json

app.use(multer);

app.use(express.static(__dirname + '/'));

//app.use(bodyParser.json());

mongoose.connect('mongodb://localhost:27017/tfdb');

var db = mongoose.connection;

db.on('error', console.error.bind(console, 'connection error:'));

db.on("open", function () {

console.log("------数据库连接成功！------");

});

router(app);

//User.create({uid:123,name:'test','phone':'12313',password:'12312321'},function (err,data) {

// if(err)

// console.log(err);

//

//

//});

console.log('you have logged in successfully!');

app.listen(5000);

求大神解答
