android - KSOAP2 和 WSDL 返回解码错误 : unexpected element

Question

我试图了解如何使用 a SOAP webservice (link to wsdl)与安卓系统。我有这个简单的方法，使用带有依赖项 jar 的 ksoap2 3.0:

public void simpleSoap() {
        String SOAP_ACTION = "";
        String METHOD_NAME = "getElement";
        String NAMESPACE = "http://www.wcc.nrcs.usda.gov/ns/awdbWebService";
        String URL = "http://www.wcc.nrcs.usda.gov/awdbWebService/services?WSDL";

        try {
            SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

            Request.addProperty("elementCd","WTEQ");

            SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            soapEnvelope.dotNet = true;
            soapEnvelope.setOutputSoapObject(Request);

            HttpTransportSE transport = new HttpTransportSE(URL);

            transport.call(SOAP_ACTION, soapEnvelope);
            resultString = (SoapPrimitive) soapEnvelope.getResponse();

            Log.i(TAG, "Result: " + resultString);
        } catch (Exception ex) {
            Log.e(TAG, "Error: " + ex.getMessage());
        }
    }

我每次都收到错误/强制关闭响应:

Error: Unmarshalling Error: unexpected element
(uri:"http://www.wcc.nrcs.usda.gov/ns/awdbWebService",
local:"elementCd"). Expected elements are <{}elementCd>

我已经在 wonderful online client 上测试过了并取得成果。我在这里错过了什么？为什么我无法获得我硬编码到 addProperty 函数中的这个简单的 elementCd WTEQ 的结果？

三周后我偶然发现了这个问题:https://stackoverrun.com/es/q/2805758

这是因为预期的命名空间必须是一个空字符串。因此，在将您的属性添加到请求时，请确保将“”放入命名空间。

您可能还想在创建请求之前添加线程策略。

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);

    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
    Request.addProperty("", "elementCd","WTEQ");
