SoapFault - 故障代码和请求肥皂与库ksoap2

Question

我尝试从android中的库ksoap2调用请求，但在android studio中收到错误：

I/System: core_booster, getBoosterConfig = false
W/System.err: SoapFault - faultcode: 'soap:Client' faultstring: 'Message part {http://rogal.ws.pl/map/thumbnail}GetThumbnail was not recognized.  (Does it exist in service WSDL?)' faultactor: 'null' detail: null

我的android代码如下所示：

public class MainActivity extends AppCompatActivity {

    public static final String SOAP_URL = "http://92e7a7ca.ngrok.io/api/map?wsdl";
    public static final String NAMESPACE = "http://rogal.ws.pl/map/MapService/";
    public static final String METHOD_NAME = "GetThumbnail";

    TextView text;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        text = (TextView) findViewById(R.id.textView);
        Button signin = (Button) findViewById(R.id.button);
        signin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                new RequestTask().execute();
            }
        });

    }

    private void req() {
        PropertyInfo propertyInfo = new PropertyInfo();
        propertyInfo.setName("Name");
        propertyInfo.setValue("hello");
        requestSoap(propertyInfo);
    }

    public void requestSoap(PropertyInfo... propertyInfos) {
        String mResponse = "";
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);

        for (PropertyInfo propertyInfo : propertyInfos) {
            request.addProperty(propertyInfo);
        }

        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        HttpTransportSE ht = new HttpTransportSE(SOAP_URL);
        ht.debug = true;
        try {
            ht.call("", envelope);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        try {
            mResponse = envelope.getResponse().toString();
            text.setText(mResponse);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private class RequestTask extends AsyncTask<Void, Void, Void> {

        protected void onPreExecute() {
            System.out.println();
        }

        protected Void doInBackground(final Void... unused) {

            System.out.println();
            req();
            System.out.println();

            return null;
        }

        protected void onPostExecute(Void result)
        {
            System.out.println();
        }

    }
}

我在清单文件中添加了权限：

java中的Web服务：here

wsdl：here

架构xsd：here

我检查了Web服务工具SoapUI的操作并正常工作。

我没有注意到可能导致此异常的错误。

我将非常感谢你的帮助
