2018-09-29 259 阅读1分钟

一、代码结构

//1.引入相关模块
var  http=require("http")
var  url=require("url")
var  fs=require("fs")
//2.创建服务以及处理请求和响应
var  server=http.createServer(function(req,res){
  //处理请求与响应部分
}
//3.监听某一个端口
server1.listen(81,function(){
    console.log("servers is success,listening on 81port!")
})

二、http.createServer

 var server=http.createServer(function(req,res){
    var pathname=url.parse(req.url).pathname
    if(pathname==="/index.html"){
        var conFile=fs.readFileSync("."+pathname,"utf-8")
        // res.writeHead(200,{'content-type':'text/html;charset=utf-8;'})
        res.statusCode = 200
        res.setHeader('Content-Type', 'text/html;charset=utf-8')
        res.end(conFile)
    }

<!-- index.html -->
<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
