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
1 <?xml version="1.0" encoding="utf-8"?> 2 <s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" 3 xmlns:s="library://ns.adobe.com/flex/spark" 4 xmlns:mx="library://ns.adobe.com/flex/mx" 5 creationComplete="init()"> 6 <fx:Declarations> 7 <!-- Place non-visual elements (e.g., services, value objects) here --> 8 </fx:Declarations> 9 <fx:Script> 10 <![CDATA[ 11 import mx.rpc.AbstractOperation; 12 import mx.rpc.events.FaultEvent; 13 import mx.rpc.events.ResultEvent; 14 import mx.rpc.remoting.mxml.RemoteObject; 15 import mx.formatters.DateFormatter; 16 17 private function init():void{ 18 var ro:RemoteObject = new RemoteObject(); 19 ro.destination = "times_get"; 20 ro.endpoint = "http://127.0.0.1:8000/gateway/"; 21 var operation:AbstractOperation = ro.getOperation("get"); 22 ro.addEventListener(ResultEvent.RESULT, resultHandler); 23 ro.addEventListener(FaultEvent.FAULT, faultHandler); 24 operation.send(); 25 26 function resultHandler(event:ResultEvent):void{ 27 trace(event.result); 28 dg.dataProvider = event.result; 29 } 30 31 function faultHandler(event:FaultEvent):void{ 32 trace(event.fault); 33 } 34 } 35 36 private function data_function(self:Object, column:DataGridColumn):String{ 37 var df:DateFormatter = new DateFormatter(); 38 //df.formatString = "YYYY-MM-DD JJ:NN:SS"; 39 df.formatString = "YYYY-MM-DD"; 40 return df.format(self.times); 41 } 42 ]]> 43 </fx:Script> 44 45 <mx:DataGrid id="dg" width="100%" height="100%"> 46 <mx:columns> 47 <mx:DataGridColumn dataField="times" headerText="时间" labelFunction="data_function"/> 48 </mx:columns> 49 </mx:DataGrid> 50 51 </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。

结果：
