                          'WebService Path',//Service路径
                          'IsSubmitByURL',//调用方法
                          true,//是否使用HttpGet
                          {'name':name},//参数
                          Onsucceeded,//OnSucceeded时回调函数
                          null,//OnFailed时回调函数
                          null,//UserContext
                          5000//TimeOut
                          );
