node.js 获取http url路径中的各个参数

若url为：

http://localhost:8888/select?name=a&id=5

http.createServer(function(request,response){        var pathname = url.parse(request.url).pathname;  //pathname => select        var arg = url.parse(request.url).query;          //arg => name=a&id=5        console.log("Request for " + arg );        var name = querystring.parse(arg).name;         //name => a        console.log("name = "+name);        console.log("Request for " + pathname + " received.");    }).listen(8888); 

//querystring.parse(arg) => { name: 'a', id: '5' }
