url的处理

var http = require("http");var server = http.createServer();var url = require("url");server.on("request",function(req,res){    //console.log(req.url);    /*?后面称为query string查询字符串*/    var urlStr = url.parse( req.url );    //console.log(urlStr);    switch (urlStr.pathname) {        case '/':            //首页            res.writeHead(200, {                'content-type' : 'text/html;charset=utf-8'            });            res.end('<h1>这是首页</h1>');            break;        case '/user':            //用户首页            res.writeHead(200, {                'content-type' : 'text/html;charset=utf-8'            });            res.end('<h1>个人中心</h1>');            break;        default:            //处理其他情况            res.writeHead(404, {                'content-type' : 'text/html;charset=utf-8'            });            res.end('<h1>页面被perfect吃掉了</h1>');            break;    }});server.on("listening",function(){    console.log("listening......")});server.listen(8084,"localhost");
