Flex调用Web服务的应用开发（一）

 

1.使用Flex绑定Web Service必须保证WebService可用情况下使用

 

<?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
        {
         tmp=event.result as String;
         Alert.show("tmp="+tmp);
        }
         //错误处理方法
        private function faultHandler(event:FaultEvent):void
        {
              Alert.show(event.fault.faultDetail);
        }
 ]]>
</mx:Script>

 <mx:WebService id="weatherWs" wsdl="http://localhost:8090/FlexWS/services/FlexWebService?wsdl" >

   //默认的参数必须：in0 ,in1，.......
     <mx:operation name="helloWord" result="resultHandler(event)" fault="faultHandler(event)">
       <mx:request>
          <in0>
           xiaoxiao
          </in0>
          <in1>
           ZH
          </in1>
       </mx:request>
     </mx:operation>
 </mx:WebService>
 <mx:Button label="查看信息" click="weatherWs.helloWord()" x="169" y="10"/>
 <!--表达式-->
 <mx:Label text="{weatherWs.helloWord.lastResult}"  y="12"/>
</mx:Canvas>

 

源代码如下：
