这次说的关于Flex的WebService来自于一位网友的贡献,看了后十分清晰,果然比纯JAVA的WebService要方便许多,只需要提供一个WebService服务地址,如中国气象局的免费服务【当然大家都知道这个界面就是个XML】:http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl
通过下面这个网址可以输入城市,查询城市天气预报
http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?op=getWeatherbyCityName
我们现在要做的就是实现这个功能,在Flex上面非常容易,贴上代码
只有一个mxml即可
<?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:Declarations>
<!-- 将非可视元素(例如服务、值对象)放在此处 -->
<mx:WebService id="webService" wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl"
showBusyCursor="true" result="onLoad(event)" fault="faultHandler(event)"/>
</fx:Declarations>
<fx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
private function onLoad(event:ResultEvent):void{
//Alert.show(event.result.toString(),"WebService Results");
var weatherInfo:ArrayCollection = (event.result) as ArrayCollection;
for(var i:int=0;i<weatherInfo.length;i++){
myWeatherReport.text+=weatherInfo[i]+"\n";
}
}
private function faultHandler(event:FaultEvent):void{
Alert.show(event.fault.toString(),'WebService Error');
}
protected function button1_clickHandler(event:MouseEvent):void
{
webService.getWeatherbyCityName(cityName.text);
}
]]>
</fx:Script>
<s:Panel x="48" y="21" width="679" height="423" title="城市天气预报查询FLEX">
<s:TextInput x="135" y="26" id="cityName"/>
<s:Label x="43" y="31" text="请输入城市名称"/>
<s:Button x="286" y="26" label="点击查询" click="button1_clickHandler(event)"/>
<s:TextArea id="myWeatherReport" x="31" y="68" width="615" height="297"/>
</s:Panel>
</s:Application>
