1_hello.js代码：
var http = require('http'); http.createServer(function (request, response) { response.writeHead(200, {'Content-Type': 'text/html; charset=utf-8'}); if(request.url!=="/favicon.ico"){ //清除第2此访问 console.log('访问'); response.write('hello,world'); response.end();//不写则没有http协议尾,但写了会产生两次访问 } }).listen(8000); console.log('Server running at http://localhost:8000/'); /*
启动服务 cmd下执行： node 1_hello.js 浏览器访问：http://localhost:8000 */
内部函数调用
