HttpTransportSE.call()抛出IllegalArgumentException

标签: android wcf

我是Android开发的新手,并努力创建一个可以使用我的wcf服务的Android客户端。下面是我的wcf服务界面。我正在返回两个函数的硬编码值。 WCF服务正在使用BasicHttpBinding。

[ServiceContract]
  public interface IAgent
    {

        [OperationContract]
        int TestMethod();

        [OperationContract]       
        string TestMethodParameter(int key);
    }

下面是android客户端代码

package com.example.test;
import android.os.Bundle;
import android.os.StrictMode;
import android.app.Activity;
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 android.view.Menu;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity
extends Activity 
implements OnClickListener
{
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
     private static final String TEST_METHOD = "IAgent/TestMethod";
     private static final String NAMESPACE = "http://tempuri.org/";
     private static final String URL = "http://odchistorian.cloudapp.net/HistorianAgent.svc";
     private static final String SOAP_ACTION1 = NAMESPACE + TEST_METHOD;
    Button connectButton = null;
    EditText editBox = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        connectButton = (Button) this.findViewById(R.id.button1);
        editBox = (EditText) this.findViewById(R.id.editText1);
        connectButton.setOnClickListener(this);
        StrictMode.setThreadPolicy(policy); 
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    public void onClick(View arg0) {

        SoapObject request = new SoapObject(NAMESPACE,TEST_METHOD); 
        final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        final HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);              
                    try {

                        androidHttpTransport.call(SOAP_ACTION1, envelope);
                        SoapPrimitive response = null;
                            response = (SoapPrimitive) envelope.getResponse();
                            String resultData= response.toString();              
                            editBox.setText(resultData);

                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }                           
    }
}

每次运行此代码时,我总是在“androidHttpTransport.call(SOAP_ACTION1,envelope);”行上获得IllegalArgumentException。我经历了几个博客,但没有运气。无法得到究竟缺失的东西。请帮忙。
