方式一：flex与Webservices与简单通信
1、格式：
flex中有个<webservices>的标签能够负责flex与webservices之间交互
view plaincopy to clipboardprint?<mx:WebService id=" WebService组件id" wsdl="WebService地址"> <mx:operation name="方法名"> <mx:request> <参数名1>值1</参数名1> <参数名2>值2</参数名2> … </mx:request> </mx:operation> </mx:WebService> <mx:WebService id=" WebService组件id" wsdl="WebService地址"> <mx:operation name="方法名"> <mx:request> <参数名1>值1</参数名1> <参数名2>值2</参数名2> … </mx:request> </mx:operation> </mx:WebService>
<mx:operation>组件表示WebService的一个方法，属性name值必须与WebService中的定义名称相同 <mx:request>标签下传递参数，需要注意的是参数的名称及顺序必须与WebService中的定义相同。
2、范例：
本实例是整理的网络上《五分钟用Flex构建WebService应用》的博客，使用的是“http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl”地址提供的天气服务数据
view plaincopy to clipboardprint?<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:WebService id="webService" wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl" showBusyCursor="true" result="onLoad(event)" fault="faultHandler(event)"/> <mx:Script> <!--[CDATA[ import mx.collections.ArrayCollection; import mx.utils.ArrayUtil; import mx.controls.Alert; import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; private function onLoad(event:ResultEvent):void { 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"); } ]]--> </mx:Script> <mx:TextInput id="cityname" text="北京" x="10" y="38"/> <mx:Button label="Call WebService" click="webService.getWeatherbyCityName(cityname.text)" x="178" y="38"/> <mx:TextArea id="myWeatherReport" height="334" width="409" editable="false" x="10" y="82"/> </mx:Application>
方式二：这里主要介绍Webservices使用AS代码的操作方法
As代码部分 view plaincopy to clipboardprint?[Bindable] public var arrayCol:ArrayCollection; public function Test():void { var webs:WebService=new WebService(); webs.wsdl="http://localhost/Web/WebService1.asmx?WSDL"; webs.loadWSDL(); webs.showBusyCursor=true; // webs.addEventListener(LoadEvent.LOAD,load); webs.addEventListener(ResultEvent.RESULT,WebsResult); webs.addEventListener(FaultEvent.FAULT,webFault); webs.GetProData(); } public function webFault(event:FaultEvent):void { Alert.show(event.toString()); } public function WebsResult(Result:ResultEvent):void { arrayCol =Result.result as ArrayCollection; } [Bindable] public var arrayCol:ArrayCollection; public function Test():void { var webs:WebService=new WebService(); webs.wsdl="http://localhost/Web/WebService1.asmx?WSDL"; webs.loadWSDL(); webs.showBusyCursor=true; // webs.addEventListener(LoadEvent.LOAD,load); webs.addEventListener(ResultEvent.RESULT,WebsResult); webs.addEventListener(FaultEvent.FAULT,webFault); webs.GetProData(); } public function webFault(event:FaultEvent):void { Alert.show(event.toString()); } public function WebsResult(Result:ResultEvent):void { arrayCol =Result.result as ArrayCollection; }
view plaincopy to clipboardprint?<mx:AdvancedDataGrid id="adg1" designViewDataType="tree" editable="true" dataProvider="{arrayCol}"> <mx:columns> <mx:AdvancedDataGridColumn headerText="CustomerID" dataField="CustomerID"/> <mx:AdvancedDataGridColumn headerText="ShipName" editable="false" dataField="ShipName"/> <mx:AdvancedDataGridColumn headerText="Freight" itemEditor="mx.controls.NumericStepper" dataField="Freight"/> </mx:columns> </mx:AdvancedDataGrid> <mx:Button label="testWeb" click="Test()"></mx:Button>
