node.js 创建一个httpsever es6

//Request 对象用于接收客户端浏览器提交的数据，而 Response 对象的功能则是将服务器端的数据发送到客户端浏览器。

let user = require('./User')
//console.log(`userame:${user.userName},say ${user.sayHello()}`)  //加载http模块 url模块 util模块 let http = require('http')
let url = require('url')
let util = require('util')

let server = http.createServer((req, res) => {
   debugger  res.statusCode = 200
   res.setHeader('Content-Type', 'text-plain;charset=utf-8')

   //用于调试，把对象打印成字符串  let urlStr = util.inspect(url.parse(req.url))
   
   console.log(req.url)//demo.html?a=12  console.log("parse:"+url.parse(req.url))//[object]  console.log('inspect:'+util.inspect(url.parse(req.url)))[url:{
      
   }]

   res.end(urlStr)
})
server.listen(3000, '127.0.0.1', () => {
   console.log("server listen http://localhost:3000")
})
