我试图做一个简单的ksoap2教程。这是

我的问题是，我只得到回应，如果我使用SoapPrimitive和KSOAP ... 2.6.4.jar与KSOAP ... 2.4.jar和或SoapObject响应=（SoapObject）envelope.getResponse（）; 我有一个例外。

我怎么也得使用SoapObject？

这是我的code：

 公共类WS_Auth_ComplexObjectsActivity延伸活动{
    / **第一次创建活动时调用。 * /

    字符串NAMESPACE =htt​​p://WS.androidroleplay.fk4.de.hs_bremen.de;
    字符串METHOD_NAME =GetSumOfTwoInts;
    字符串SOAP_ACTION =htt​​p://WS.androidroleplay.fk4.de.hs_bremen.de/GetSumOfTwoInts;
    字符串的URL =htt​​p://192.168.178.28:8080/WebProject_DB16/services/HelloWorldWS?wsdl;

    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;

        SoapObject请求=新SoapObject（命名空间METHOD_NAME）;

        的PropertyInfo PI =新的PropertyInfo（）;
        pi.setName（操作数）;
        pi.setValue（2）;
        pi.setType（int.class）;
        Request.addProperty（PI）;

        的PropertyInfo PI2 =新的PropertyInfo（）;
        pi2.setName（和Operand2）;
        pi2.setValue（5）;
        pi2.setType（int.class）;
        Request.addProperty（PI2）;

        SoapSerializationEnvelope包=新SoapSerializationEnvelope（SoapEnvelope.VER11）;

        envelope.setOutputSoapObject（请求）;

// envelope.addMapping（命名空间中，整数，）;
        HttpTransportSE androidHttpTransport =新HttpTransportSE（URL）;

        尝试
        {
             //没有得票数folgt死Authentifikation MIT数字高程模型用户管理UND Passwort管理
            名单＆LT; HeaderProperty＆GT; headerList =新的ArrayList＆LT; HeaderProperty＆GT;（）;
            headerList.add（新HeaderProperty（授权，基本+ org.kobjects.base64.Base64.en code（雄猫：雄猫.getBytes（））））; // 用户名密码

            androidHttpTransport.call（SOAP_ACTION，信封，headerList）;
            androidHttpTransport.debug = TRUE;

            SoapObject响应=（SoapObject）envelope.getResponse（）;
            字符串结果= response.getAttributeAsString（0）;

            TextView的电视=（TextView中）findViewById（R.id.TextView）;
            tv.setText（文字：​​+结果）; //的CategoryId：+ C.getCategoryId（）+姓名：+ C.getName（）+描述：+ C.getDescription（）
        }
        赶上（例外五）
        {
            e.printStackTrace（）;
        }
    }
}
 

和本我的web服务：

 公共类HelloWorldWS
{

    公众诠释GetSumOfTwoInts（INT操作数，整数和Operand2）
    {
        的System.out.println（操作数+++和Operand2 +=+（操作数+ Operand2中））;

       返回操作数1 + Operand2中;
    }


}
 

解决方案

您服务方法只返回一个整数值。在ksoap2，如果web服务响应只有一个值（整数，字符串..），你应该使用

  SoapPrimitive响应=（SoapPrimitive）envelope.getResponse（）;
 

和 response.toString（）; 的结果是你想要的。 如果你的回答有复杂类型（对象），你应该使用

  SoapObject响应=（SoapObject）envelope.getResponse（）;
 

和解析它。

i tried to do a simple ksoap2 tutorial. This is the link

My Problem is, I only get a response, if I use SoapPrimitive and Ksoap...2.6.4.jar with Ksoap...2.4.jar and or "SoapObject response = (SoapObject)envelope.getResponse();" I've got an exception.

How i have to use the SoapObject?

This is my Code:

public class WS_Auth_ComplexObjectsActivity extends Activity {
    /** Called when the activity is first created. */

    String NAMESPACE = "http://WS.androidroleplay.fk4.de.hs_bremen.de";
    String METHOD_NAME = "GetSumOfTwoInts";
    String SOAP_ACTION = "http://WS.androidroleplay.fk4.de.hs_bremen.de/GetSumOfTwoInts";
    String URL = "http://192.168.178.28:8080/WebProject_DB16/services/HelloWorldWS?wsdl";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

        PropertyInfo pi = new PropertyInfo();
        pi.setName("Operand1");
        pi.setValue(2);
        pi.setType(int.class);
        Request.addProperty(pi);

        PropertyInfo pi2 = new PropertyInfo();
        pi2.setName("Operand2");
        pi2.setValue(5);
        pi2.setType(int.class);
        Request.addProperty(pi2);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

        envelope.setOutputSoapObject(Request);

//        envelope.addMapping(NAMESPACE, "Integer",);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try
        {
             // Hier folgt die Authentifikation mit dem User Admin und Passwort Admin
            List<HeaderProperty> headerList = new ArrayList<HeaderProperty>();
            headerList.add(new HeaderProperty("Authorization", "Basic " + org.kobjects.base64.Base64.encode("tomcat:tomcat".getBytes()))); // "username:password"

            androidHttpTransport.call(SOAP_ACTION, envelope, headerList);
            androidHttpTransport.debug=true;

            SoapObject response = (SoapObject)envelope.getResponse();
            String result =  response.getAttributeAsString(0);

            TextView tv = (TextView)findViewById(R.id.TextView);
            tv.setText("Text: " + result); //"CategoryId: " +C.getCategoryId() + " Name: " + C.getName() + " Description: " + C.getDescription()
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

And this my Webservice:

public class HelloWorldWS
{   

    public int GetSumOfTwoInts(int Operand1, int Operand2 )
    {
        System.out.println(Operand1+ " + "+ Operand2 +" = "+ (Operand1 + Operand2));

       return Operand1 + Operand2;
    }


}

Your service method returns only a integer value. In ksoap2, if webservice response has only one value(integer, string..) you should use

SoapPrimitive response = (SoapPrimitive) envelope.getResponse();

and response.toString(); is result that you want. If your response has complex types (Objects), you should use

SoapObject response = (SoapObject) envelope.getResponse();

and parse it.
