Node quickly builds a service

First, introduce the http module

let http=require('http');

Then introduce url: get routing parameter npm i url

let url=require('url');

then create the service

let server=http.createServer(function(req,res){
    
    
	//从请求中拿到路由参数
	let params=url.parse(req.url);
	res.statusCode=200;  //正确的状态吗
	//设置请求头
	res.setHeader('Content-Type','application/json;charset=utf-8')
	//给前端的响应结果
	res.end(`{"errCode":0,"msg":"${
      
      params.search}"}`);
})

Finally start the service

server.listen(8888,function(){
    
    
	console.log("服务启动成功");
})

Stop the service here with ctrl + c
