Android Ksoap2 Web服务功能

所以我尝试调用ksoap2webservices并从中获取一些数据，但我一直得到一个错误，没有输出。在webservices上有一个名为HelloWorld的部分，它只用于测试，它可以工作，我得到了正确的输出，但是当我试图从这个部分访问数据时，它不工作，不断地出错

代码如下：

private String SOAP_ACTION = "http://microlise.com/TMC/FindConsignmentSummaries";

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.home_page);

    MyTask myTask = new MyTask();
    myTask.execute();

}

@Override
public void onClick(View v){
}

public class MyTask extends AsyncTask<String, Integer, String> {

    @Override
    protected String doInBackground(String... params) {

        SoapObject request = new SoapObject(NAME_SPACE, METHOD_NAME);

        //request.addProperty("HelloWorld","");

        SoapObject filter = new SoapObject( NAME_SPACE,"consignmentFilter");
        filter.addProperty("ConsignmentReference","");
        filter.addProperty("OrderReference","");
        filter.addProperty("EarliestDeliveryDate","");
        filter.addProperty("LatestDeliveryDate","");
        filter.addProperty("SiteID","");
        filter.addProperty("SiteName","");


        request.addSoapObject(filter);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransportSE = new HttpTransportSE(url);
        httpTransportSE.debug = true;
        String requestDump = httpTransportSE.requestDump;
        String responseDump = httpTransportSE.responseDump;
        try {

            List<HeaderProperty> headersProperty = new ArrayList<>();
            headersProperty.add(new HeaderProperty("Authorization", "Basic " + android.util.Base64.encodeToString("username:pass".getBytes(), Base64.NO_WRAP)));    //org.kobjects.base64.Base64.encode("Technet:CEVA".getBytes())));
            httpTransportSE.call(SOAP_ACTION, envelope, headersProperty);
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

            Log.d("RESULT_IS", " " + response.toString());
            Log.d("DEBUG_RESULT", " " + requestDump + " /" + responseDump);

        }
        catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

    protected void onPostExecute () {

    }
}
}

你知道哪里不对吗？谢谢你们
