读取：

read.js

//导入http
    var http = require('http');
    var optfile = require('../module/optfile.js');
    //创建
    http.createServer(function (request,response) {
        response.writeHead(200,{'Content-type':'text/html;charset=utf-8'});
        if(request.url !== '/favicon.ico'){//清除二次访问
            console.log('访问');
            //闭包，回调这个函数,客户端打印程序
            function recall(data){
                response.write(data);
                response.end("");
            }
            // optfile.readfileSync('../view/login.html');
            optfile.readfile('../view/login.html',recall)
            // response.end("世界");//不写会没有协议尾部，但是写了会访问俩次
            console.log('主程序执行完毕');
        }
    }).listen(8001);
    console.log('Server running at http://127.0.0.11:8001/')

**利用路由，传入不同的页面读取不同的数据：**

router.js

readfile.js

//导入http
    var http = require('http');
    // var optfile = require('../module/optfile.js');
    var url=require('url');
    var router = require('../module/router.js');
    //创建
    http.createServer(function (request,response) {
        response.writeHead(200,{'Content-type':'text/html;charset=utf-8'});
        if(request.url !== '/favicon.ico'){
            
            var pathname=url.parse(request.url).pathname;
            pathname=pathname.replace(/\//,'');//替换前面/
            console.log(pathname);
            router[pathname](request,response);
           
        }
    }).listen(8021);
    console.log('Server running at http://127.0.0.11:8021/');
