Flex 调用声明式调用Ws

 

本功能在页面初始化调用Web 服务，并且调用多个方法

使用mx:WebService 中load属性初始化调用的方法的应用

 

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" width="400" height="300"  >

<mx:Script>
 <![CDATA[
  import mx.collections.ArrayCollection;
  import mx.controls.Alert;
  import mx.rpc.soap.LoadEvent;
  
  import mx.rpc.events.FaultEvent;
  import mx.rpc.events.ResultEvent;
  
  [Bindable]
  private var dataList:ArrayCollection;
  [Bindable]
  private var tmp:String;
  //事件绑定处理方法
        private function resultHandler(event:ResultEvent):void
        {
         //强制转换为字符串
         tmp=event.result as String;
         Alert.show("tmp="+tmp);
        }
        private function resultHandlerList(event:ResultEvent):void
        {
         //强制转换为集合
            dataList=event.result as ArrayCollection;
            Alert.show(" dataList = "+dataList);
        }
         //错误处理方法
        private function faultHandler(event:FaultEvent):void
        {
              Alert.show(event.fault.faultDetail);
        }
 ]]>
</mx:Script>

<!---注意此处的初始化加载时进行调用Ws服务，并且调用多个服务的方法-->

 <mx:WebService id="weatherWs" wsdl="http://localhost:8090/FlexWS/services/FlexWebService?wsdl" load="weatherWs.getList()" >
    
      <mx:operation name="helloWord" result="resultHandler(event)" fault="faultHandler(event)">
        <mx:request>
           <in0>
            xiaoxiao
           </in0>
           <in1>
            ZH
           </in1>
        </mx:request>
     </mx:operation>
     <mx:operation name="getList" result="resultHandlerList(event)" fault="faultHandler(event)"/>
 </mx:WebService>
 <mx:Button label="查看信息" click="weatherWs.helloWord()" x="101" y="10"/>
 <!--表达式-->
 <mx:Label text="{weatherWs.helloWord.lastResult}"  y="12" x="260"/>
 
 <mx:DataGrid dataProvider="{dataList}"     x="24.5" y="107" width="351">
    <mx:columns>
        <mx:DataGridColumn dataField="dataList"   headerText="aa"/>
    </mx:columns>
 </mx:DataGrid>
 
 
</mx:Canvas>
