Flex调用Webservice时可能产生的所有错误，监控哪些错误

判断web服务是否没有方法，是否路径错误，是否编码错误，是否解码错误，等等错误
由于网上很少有相关资料，我自己整理，查看sdk总结而得


private var webserviceURL:WebService = new WebService();
webserviceURL.addEventListener(LoadEvent.LOAD,loadWebHandle);
webserviceURL.addEventListener(FaultEvent.FAULT,webFaultHandle);
webserviceURL.addEventListener(ResultEvent.RESULT,rezultHandle);



private function loadWebHandle(e:LoadEvent):void{
    
    webserviceURL.removeEventListener(FaultEvent.FAULT,webFaultHandle);
    webserviceURL.removeEventListener(LoadEvent.LOAD,loadWebHandle);
    trace("加载完成");
   }
   private function webFaultHandle(e:FaultEvent):void{
    webserviceURL.removeEventListener(FaultEvent.FAULT,webFaultHandle);
    webserviceURL.removeEventListener(LoadEvent.LOAD,loadWebHandle);
    trace("调用错误");
   }
   private function rezultHandle(e:ResultEvent):void{
    webserviceURL.removeEventListener(FaultEvent.FAULT,webFaultHandle);
    webserviceURL.removeEventListener(LoadEvent.LOAD,loadWebHandle);
    trace("调用成功");
}


Operation 中可能产生的错误
var fault2:Fault = new Fault("EncodingError", errorMsg);
var fault2:Fault = new Fault("DecodingError", errorMsg);
var fault:Fault = new Fault("Client.MustUnderstand", msg);
var errMsg:String = "Cannot invoke method " + name + " as WSDL did not load successfully";
dispatchRpcEvent(createFaultEvent("Client.InvalidWSDL", errMsg));
F("Client.NoSuchMethod", "Couldn't find method '" + name + "' in service."

WebServic 中可能产生的错误
//mustSpecifyWSDLLocation
var fault:Fault = new Fault("Client.WSDL", message);
//destinationOrWSDLNotSpecified
var fault:Fault = new Fault("Client.WSDL", message);
//unexpectedException
var fault:Fault = new Fault("WSDLError", message);
var fault:Fault = new Fault("ConcurrencyError", message);

举例：
<mx:WebService id="ws_UserControl" fault="wsfault(event)"
wsdl="http://172.*.*.11:8080/cb_test/user?wsdl"
      useProxy="false"  showBusyCursor="true" requestTimeout="10">
<mx:operation name="login" result="result(event)" fault="fualt(event)" />
</mx:WebService>


private function wsfault(event:FaultEvent)
{
  var str:String = event.fault.FaultCode;
  //根据str来判断错误类型，如果是WSDLError，表明是unexpectedException，以此类推
}
private function fault(event:FaultEvent)
{
  var str:String = event.fault.FaultCode;
  //根据str来判断错误类型，如果是Client.NoSuchMethod，表明没有该方法，以此类推，以上operation中的均可以通过此来判断
}
