URLLoader非常簡單封裝

非常簡單的URLLoader封裝，支持參數和回調函數，默認POST。

public static function HttpRequest(url:String, parms:Array, callback:Function):void{
            var _request:URLRequest = new URLRequest(url);
            var _vars:URLVariables = new URLVariables();
            var _loader:URLLoader;
            var i:int;

           
            for (i = 0; i < parms.length;i++ ){
                _vars[parms[i][0]] = parms[i][1];
            }
            _request.method = URLRequestMethod.POST;
            _request.data = _vars;
            
            _loader = new URLLoader(_request);
            _loader.addEventListener(Event.COMPLETE, callback);
            _loader.load(_request);
        }
