nodejs构建本地web测试服务器 如何解决访问静态资源问题

var express = require('express');
var app = express();
var path = require('path');

//指定静态资源访问目录
app.use(express.static(require('path').join(__dirname, 'public')));
// app.use(express.static(require('path').join(__dirname, 'views'))); 如果有文件夹存放资源，出现报错的话，那就多use几次就可以了
// 设定views变量，意为视图存放的目录
app.set('views', (__dirname + "/public"));
// app.set('views', __dirname);
// 修改模板文件的后缀名为html
app.set( 'view engine', 'html' );
// 运行ejs模块
app.engine( '.html', require( 'ejs' ).__express );

app.get("/", function(req, res) {
  res.render('index');
});

var server = app.listen(1336, "127.0.0.1",function(){
  var host = server.address().address;
  var port = server.address().port;
  console.log("Server running at http://%s:%s", host, port)
});

 var connect = require("connect");
 var serveStatic = require("serve-static");

 var app = connect();
 // app.use(serveStatic("C:\\xxx\\xxx\\xxx\\项目文件夹"));
 app.use(serveStatic("public"));

 app.listen(1337);
 console.log('Server running at http://127.0.0.1:1337/');

var finalhandler = require('finalhandler')
var http = require('http')
var serveStatic = require('serve-static')

// Serve up public/ftp folder
var serve = serveStatic('public', {'index': ['index.html', 'index.htm']})

// Create server
var server = http.createServer(function onRequest (req, res) {
  serve(req, res, finalhandler(req, res))
})

// Listen
server.listen(1338);
console.log('Server running at http://127.0.0.1:1338/');
