nodeJS 之 hello world！

var http = require('http');
function onRequest(resquest, response){
        response.writeHeader(200, "Conten-Type":"text/html");
        response.write('hello world');
	response.end();
}
http.createServer(onRequest).listen(8080);

下載nodesJS,windows下執行cmd，進入helloworld.js所在目錄，執行node helloworld.js。

則服務器已經啓動，瀏覽器訪問localhost:8080，便可在瀏覽器上顯示hello world;
