从Android应用程序调用web服务返回空对象

Question

我正在编写一个使用KSOAP与web服务通信的Android应用程序。web服务和Android应用程序之间的连接正在工作，因为我可以调用web服务并获得返回值(hello)。但是，如果我试图通过. addproperty从应用程序给web服务一个名称，web服务返回一个空对象。

下面是我的代码:

MainActivity:

private final String NAMESPACE_Local = "http://test.com/";  
    private final String URL_Local = "http://168.185.226.21:7001/myTest/myTestWebServiceService";
  private final String SOAP_ACTION_Local = "Hello_Action_Extend";
   private final String METHOD_NAME_Local = "hello_extend";
    public void LocalServer(View view)
    {
        TextView text = (TextView) findViewById(R.id.update_text);
        SoapObject request = new SoapObject(NAMESPACE_Local, METHOD_NAME_Local);
        request.addProperty("name", "Christian");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL_Local);
        try {
            androidHttpTransport.call(SOAP_ACTION_Local, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            Log.i("myApp", response.toString());

            text.setText(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
            Toast.makeText(this,"Device or service offline",Toast.LENGTH_LONG).show();
        }
    }

网络服务器:

package com.test;
import javax.jws.*;
@WebService
public class myTestWebService {
    @WebMethod(action="Hello_Action") //that method works
    public String hello() {
        return "hello";
    }
    @WebMethod(action="Hello_Action_Extend")
    public String hello_extend(String name) //that works also, but it is giving back "hello null"
    {
        return "hello "+name;
    }
}

我希望你能帮助我!

Answer 1

尝试替换:

request.addProperty("name", "Christian");

为:

request.addProperty("name",ElementType.STRING_CLASS, "Christian");

和

的响应

SoapObject reponse=(SoapObject)envelope.getResponse();
response.getProperty("name");

API SoapObject
