Question

在所有使用REST Webservice的项目之前，我在SOAP / WSDL调用Webservice中是一个新手。经过大量的教程和示例之后，我尝试在我的Android项目中调用SOAP / WSDL文件webservice，但是当我调用logCat show error时，如下所示：

LogCat错误：

我知道错误404的意思是，也许我使用的链接是错误的，但是这里还有其他地方我做错了什么。是我的NAMESPACE，ACTIONNAME，URL，METHODNAME是正确的吗？

这是我的WSDL文件，

        <wsdl:message name="IMessageBroker_HelloWorld_InputMessage">

        </wsdl:message>
        <wsdl:message name="IMessageBroker_HelloWorld_OutputMessage">

   <wsdl:portType name="IMessageBroker">

   message="tns:IMessageBroker_HelloWorld_OutputMessage"/>
   </wsdl:operation>
   </wsdl:portType>
   </wsdl:definitions>

所以在我的Android项目中，我这样称呼：

String SOAP_ACTION = "http://tempuri.org/IMessageBroker/HelloWorld";
String METHOD_NAME = "HelloWorld";
String NAMESPACE = "http://tempuri.org/";
String URL = "http://13.76.153.12/OBS/MessageBroker.svc?wsdl";

 try {
       SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);
       SoapSerializationEnvelope soapSerializationEnvelope 
       = new SoapSerializationEnvelope(SoapEnvelope.VER12);
       soapSerializationEnvelope.dotNet = true;
                        Log.d("test", "URL = " + URL);
                        Log.d("test", "request= " + request.toString());

     soapSerializationEnvelope.setOutputSoapObject(request);
     HttpTransportSE transportSE = newHttpTransportSE(URL);
     transportSE.debug = true;
     transportSE.call(SOAP_ACTION, 
     soapSerializationEnvelope);

    String result = soapSerializationEnvelope.getResponse().toString();
     MyProperties.showLogD("wsdl", "login: " + result);
     Log.i("Success", "calculate: " + result);
      } catch (Throwable e) {
       Log.d("test", "Error - " + e.toString());
       e.printStackTrace();
       }

我的PM表示此API仍在开发中，但是第三部分表示他可以在以下链接中访问此HelloWorld方法：http://13.76.153.12/OBS/MessageBroker.svc/HelloWorld。那是什么让我感到困惑，为什么他可以使用该链接访问HelloWorld方法，如何获得该链接，WSDL文件中是否存在？。当我尝试使用SOAPUi时，请求方法什么也不显示。

现在我想知道为什么会这样，这是因为WSDL正在开发中，但是为什么测试人员（第三方）可以看到Hello World的结果，他是如何做到的。然后请检查我的NAMESPACE，ACTIONNAME，URL，METHODNAME是否正确？提前致谢。

注意：现在没有人可以帮助我，我是这里唯一的Android开发人员。

使用KSOAP库进行调用时WSDL调用获取错误
