Flex4與WebService通信

首先需要一個需要提供一個WebService服務。 這裏用一個天氣預報的webservice爲例，如中國氣象局的免費服務http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

通 過下面這個網址可以輸入城市，查詢城市天氣預報

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?op=getWeatherbyCityName

 

下面開始示例:

xml代碼:

<?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <!--[CDATA[ import mx.controls.Alert; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; //調用成功 protected function webservice_resultHandler(event:ResultEvent):void { message.text = (String)(event.result); } //調用失敗 protected function webservice_faultHandler(event:FaultEvent):void { Alert.show("調用失敗了," + event.fault.message as String, "提示"); } protected function serach_clickHandler(event:MouseEvent):void { webservice.getWeatherbyCityName(city.text); } ]]--> </fx:Script> <fx:Declarations> <!-- 將非可視元素（例如服務、值對象）放在此處 --> <s:WebService id="webservice" wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl" result="webservice_resultHandler(event)" fault="webservice_faultHandler(event)" showBusyCursor="true" /> </fx:Declarations> <s:TextInput x="138" y="85" id="city"/> <s:Button x="298" y="86" label="Search" id="serach" click="serach_clickHandler(event)" /> <s:TextArea x="138" y="136" width="441" id="message"/> </s:Application>

OK,運行應用程序，輸入城市名稱,you can see:
