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 -->
