1、建立n4_root.js
var ???http ???= ???require(‘http‘);var ???url ???= ???require(‘url‘); //这是node.js中自带的var ???router ???= ???require(‘./router‘);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; ???????????????//request.url就拿到了输入框中的url ???????????????//console.log(pathname); ???????????????pathname ???= ???pathname.replace(/\//, ???‘‘);//替换掉前面的/ ???????????????//console.log(pathname); ???????????????router[pathname](request,response); ???????????????response.end(‘‘); ???????}}).listen(8888);console.log(‘Server ???running ???at ???http://127.0.0.1:8888/‘); ??通过var ???pathname ???= ???url.parse(request.url).pathname;是获得根目录的路径 ?http://127.0.0.1:8888（根目录）是个/
通过pathname = pathname.replace(/\//, ‘‘);//替换掉前面的/ ?并且输入http://127.0.0.1:8888/login 会显示login
拿到login之后就可以进行之后的操作
新建一个router.js
module.exports={ ???login:function(req,res){ ???????res.write("我是login方法"); ???}, ???zhuce:function(req,res){ ???????res.write("我是注册方法"); ???}} 调用之后的结果是这样的
node.js中的路由（url）初步
