Android使用的WCF .NET服务返回“找不到名称空间为'http://www.w3.org/2005/08/addressing'的操作标头”

Question

我有一个Android应用程序正在使用的WCF .NET Web服务。 我们正在使用KSoap2库，并且通过搜索和寻找答案已尽我们所能。

这是我们的Android代码：

static final String NAMESPACE = "https://services.ostara.com/StellarService/";
static final String URL = "https://services.ostara.com/StellarService/StellarService.svc";
static final String SOAP_ACTION = "https://services.ostara.com/StellarService/getNextBagNumber";
static final String METHOD_NAME = "getNextBagNumber";

SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);

        PropertyInfo info = new PropertyInfo();
        info.setName("apiKey");
        info.setValue("16bb9027-4a49-4d24-899a-xxxxx");
        info.setType(String.class);
        soapObject.addProperty(info);



        SoapSerializationEnvelope envelope = new 
        SoapSerializationEnvelope(SoapEnvelope.VER12);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(soapObject);
        HttpTransportSE httpTransportSE = new HttpTransportSE(URL);

        httpTransportSE.call(SOAP_ACTION, envelope);
        SoapPrimitive soapPrimitive = (SoapPrimitive)envelope.getResponse();

想知道问题可能出在哪里，为什么我们得到以下错误：没有给定消息的名称空间为' http://www.w3.org/2005/08/addressing '的Action标头。
