Ksoap2 webservices功能

Question

所以我试图调用ksoap2 webservices并从中获取一些数据，但我一直收到错误而没有输出。在webservices上有一个名为HelloWorld的部分，它只用于测试并且它可以工作，我得到了正确的输出，但是当我试图从这个部分访问数据并且它不起作用时不断出错。

这是代码：

import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Base64;
import android.util.Log;
import android.view.View;
import android.widget.MediaController;
import android.widget.VideoView;

import org.ksoap2.HeaderProperty;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;    
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

import java.util.ArrayList;
import java.util.List;

public class HomeActivity{

private String SOAP_ACTION = "http://microlise.com/TMC/FindConsignmentSummaries";
private String NAME_SPACE = "http://microlise.com/TMC";
private String METHOD_NAME = "FindConsignmentSummaries";
private String url = "https://ws2.microlise.com/canon_live_webservice/TMCWebService.asmx?WSDL";

@Override
protected void onCreate(Bundle savedInstanceState) {
    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 () {

    }
}
}

这是xml：

Host: ws2.microlise.com
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

    <FindConsignmentSummaries xmlns="http://microlise.com/TMC">

    <SitePostCode xmlns="http://microlise.com/webservices/TMC/">string</SitePostCode>
  </consignmentFilter>
</FindConsignmentSummaries>
 </soap12:Body>
</soap12:Envelope>

这就是我得到的错误：

Code: soap:Sender, Reason: Server was unable to read request. ---

任何想法可能出错？谢谢你们
