用 nodejs 模拟服务器和前端网页；首先看下 request.url 里面是什么；

var http=require("http");
var url=require("url");
var fs=require("fs");
http.createServer(function(request,response ){
var urlObj=url.parse(request.url,true);
response.end(JSON.stringify(urlObj));
}).listen(8088);
|
结果树下：
//rul输入的是：http://localhost:8088/abcd/e/g/zzzz.html?name=rose&age=22
/* {"protocol":null,"slashes":null,"auth":null,"host":null,"port":null,"hostname":null,"hash":null,"search":"?name=rose&age=22","query":{"name":"rose","age":"22"},"pathname":"/abcd/e/g/zzzz.html","path":"/abcd/e/g/zzzz.html?name=rose&age=22","href":"/abcd/e/g/zzzz.html?name=rose&age=22"}*/
通过访问不同的目录展现不同的页面；

response.writeHead(404);

}
