来自 AS3 的 SOAP Web 服务，没有 Flex？

Question

在不使用 Flex 框架的情况下，从 ActionScript 3 调用 SOAP Web 服务的最佳库/包/类是什么？

Answer 1

推荐阅读： 具有设计模式的高级 ActionScript 3 通过乔伊洛特和丹尼帕特森 转到第 15 章以获得更好、更完整的解决方案。

我的示例代码：

private var xmlResults:XML = new URLLoader;
private var urlLoader:URLLoader = new URLLoader();


public function fErrorHandler(e:IOErrorEvent):void {
   trace("xml failed!");
        }


//when the "loader" event object finishes the loading of the xml file, run other needed functions to process the data 
private function fLoaderCompleteHandler(event:Event):void {

   trace("xml loaded!!"); //jwt testing
   var result2:XML = new XML(urlLoader.data); // loads the xml file data into the xml object
   xmlResults = result2; //have the global xml object equal the current data loaded xml object 
   result2 = null; // dont need current xml object any more so erase it

   fParseXML(0); //process the first set of records from the xml object
   trace("found xml" + xmlResults.toString()); 
        } 


public function fParseXML(intAddNum:Number):void{
   //create variables to store the record info
   //
   var envelope:XML = xmlResults; //XML(urlLoader.data);
   var soap:Namespace = envelope.namespace("soap");
   var responseN:Namespace = new Namespace("http://www.domain.com/school/ServiceCollege");
   var resultL:XMLList = envelope.soap::Body.responseN::HelloTestResponse.responseN::HelloTestResult;

   var strTest:String;
   //if only one response field will be return by the web service
   strTest = resultL; 
   //do something like this if multiple  response feilds will be returned
   //strTest = resultL.response::schoolName.toString(); 
   trace("parsing:" + strTest);
   trace("done loading:");
  }


 public function fBeginRequest():void{
  var strXMLDataRequest:String
  var urlRequest:URLRequest = new URLRequest();
  urlRequest.contentType = "text/xml; charset=utf-8";
  urlRequest.method = "POST";
  urlRequest.url = "http://www.domain.com/school/serviceCollege.asmx";  
  var soapAction:URLRequestHeader = new URLRequestHeader("SOAPAction","http://www.domain.com/school/ServiceCollege/HelloTest");
  urlRequest.requestHeaders.push(soapAction);
  strXMLDataRequest = "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
   strXMLDataRequest = strXMLDataRequest + "<soap:Body>";
   strXMLDataRequest = strXMLDataRequest + "<HelloTest xmlns=\"http://www.domain.com/school/ServiceCollege\" />";
   strXMLDataRequest = strXMLDataRequest + "</soap:Body>";
   strXMLDataRequest = strXMLDataRequest + "</soap:Envelope>";
    urlRequest.data =  new XML(strXMLDataRequest);
     urlLoader.load(urlRequest);
      urlLoader.addEventListener(IOErrorEvent.IO_ERROR, fErrorHandler); //add the event to the "loader" object
      urlLoader.addEventListener(Event.COMPLETE, fLoaderCompleteHandler); //add the event to the "loader" object
 }

肥皂请求：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <HelloTest xmlns="http://www.domain.com/school/ServiceCollege" />
  </soap:Body>
</soap:Envelope>

肥皂反应：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <HelloTestResponse xmlns="http://www.domain.com/school/ServiceCollege">
      <HelloTestResult>string</HelloTestResult>
    </HelloTestResponse>
  </soap:Body>
</soap:Envelope>

我发现this post 非常有用。 总的来说，这是一个很好的提示：添加一个 swc 以在 Flash 中启用 Flex 类。

Answer 3

您是否有不想使用 flex 库的原因？据我了解，仅在应用程序中使用您需要的组件不会给您带来任何性能问题。

不过看看：http://alducente.wordpress.com/2007/10/27/web-service-in-as3-release-10/

我不确定它是否是最好的，但我的一位同事向 e 推荐了它。
