node启动一个本地服务

在文件所在的文件目录，终端运行node nodeService.js 前提是电脑已经安装了node环境

// nodeService.js
var http = require("http");
 
http.createServer(function(request, response) {
    response.writeHead(200, {
        "Content-Type" : "text/plain"
    });
    response.write("Welcome to Nodejs");
    response.end();
}).listen(8000, "127.0.0.1");
 
console.log("Creat server on http://127.0.0.1:8000/");

var http = require("http");
 
http.createServer(function(request, response) {
    // 省略掉这部分也不受影响，只是声明一下response的内容用什么方式解析
    //response.writeHead(200, {
    //    "Content-Type" : "text/plain"
    //});
    response.write("Welcome to Nodejs");
    response.end();
}).listen(8000, "127.0.0.1");
 
console.log("Creat server on http://127.0.0.1:8000/");
