node_lujiafeng/server.js

this is my first node project

var http = require('http');  //require是node自带的http模块

http.createServer(function (request,response) {  //createServer是 http 模块提供的函数
    //发送HTTP头部
    //HTTP状态值： 200 ： ok
    //内容类型： text/plain
    response.writeHead(200,{'Content-Type':'text/plain'});
    
    //发送响应数据"hello"
    response.end('hello world\n');
}).listen(8888);

//终端打印如下信息
console.log('Server running at http://127.0.0.1:8888/')；
