flex RemoteObject 的两种使用方法

这里使用的是django1.6 和 postgreSQL9.0  FlashBuilder4.5

django方面就不说了，根据文档来做，建好模块,配置好数据库等等

创建 gateway 和 times_get

在url.py加上路径

现在来看 RemoteObject 的两种方法

第一种

             import mx.rpc.AbstractOperation;
             import mx.rpc.events.FaultEvent;

             import mx.rpc.remoting.mxml.RemoteObject;
             import mx.formatters.DateFormatter;

             private function init():void{
                 var ro:RemoteObject = new RemoteObject();
                 ro.destination = "times_get";
                 ro.endpoint = "http://127.0.0.1:8000/gateway/";
                 var operation:AbstractOperation = ro.getOperation("get");
                 ro.addEventListener(ResultEvent.RESULT, resultHandler);
                 ro.addEventListener(FaultEvent.FAULT, faultHandler);
                 operation.send();

                 function resultHandler(event:ResultEvent):void{
                     trace(event.result);
                     dg.dataProvider = event.result;
                 }

                 function faultHandler(event:FaultEvent):void{
                     trace(event.fault);
                 }
             }

             private function data_function(self:Object, column:DataGridColumn):String{
                 var df:DateFormatter = new DateFormatter();
                 //df.formatString = "YYYY-MM-DD JJ:NN:SS";
                 df.formatString = "YYYY-MM-DD";
                 return df.format(self.times);
             }
         ]]>
     </fx:Script>

     <mx:DataGrid id="dg" width="100%" height="100%">
         <mx:columns>
             <mx:DataGridColumn dataField="times" headerText="时间" labelFunction="data_function"/>
         </mx:columns>
     </mx:DataGrid>

 </s:WindowedApplication>

如果要使用其他方法 只要把

ro.getOperation("get");的get换成你想要的方法名就行。

operation.send();把想传送的数据放到括号里就行。

第二种
