Android Ksoap2 - 复杂类型(请求和响应)

Man*_*noj 2 android web-services ksoap2

我正在使用kso​​ap2来调用Android中的java webservice.Java Web服务方法是,

ImageProcessImpl.java

public UserResponse sample(UserRequest userRequest) {
     return ImageProcessDAO.sample(userRequest);
}

ImageProcessDAO.java

public static String sample(UserRequest userRequest) {

     UserResponse UserResponse = new UserResponse();
     userResponse.setMessage("SUCCESS");
     return userResponse;
}

我从Android调用这些web服务,

try{
        String NAMESPACE = "http://impl.test.com";
        String URL = "http://10.0.2.2:8080/Webservice/services/ImageProcessImpl?wsdl";  
        String SOAP_ACTION = "http://impl.test.com/sample";
        String METHOD_NAME = "sample";

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

        UserRequest userRequest = new UserRequest();            
        userRequest.setClientName("Test");

        PropertyInfo pi = new PropertyInfo();
        pi.setName("userRequest");
        pi.setValue(userRequest);
        pi.setType(UserRequest.class);
        request.addProperty(pi);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
        envelope.setOutputSoapObject(request);  
        envelope.implicitTypes = true;
        envelope.addMapping(NAMESPACE, "UserResponse", UserResponse.class);

        AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);  
        httpTransport.debug = true;
        httpTransport.call(SOAP_ACTION, envelope);

       UserResponse response = (UserResponse) envelope.getResponse(); 
       Log.e(Test.LOG_TAG, response.getMessage());
        }catch (Exception e) {
            Log.e(Test.LOG_TAG, "throws an exception: " + e.getMessage());
        }

但我在我的Logcat中得到的错误是" 抛出异常:无法序列化:com.test.common.UserRequest ".如何解决这个错误？这是调用复杂类型的Web服务的正确方法吗？

我用过KvmSerializable.我private Client[] clientNameList = null;在UserRequest.java中添加了一个数组bean变量 .

当我调用Web服务时,它在请求中工作正常.但在响应中,我得到一个包含所有值的字符串.响应字符串如下所示.

anyType{clientNameList=anyType{clientNameList=anyType{clientID=1; }; clientNameList=anyType{clientID=2; }; }; message=SUCCESS; }.

我该如何解析这个字符串？

UserResponse.java

public class UserResponse implements KvmSerializable{

public String message = null;
public Client[] clientNameList = null;

@Override
public Object getProperty(int index) {
    switch (index){
    case 0:
        return message;
    case 1:
        return clientNameList;
     default:
         return null;
    }
}

@Override
public int getPropertyCount() {
    // TODO Auto-generated method stub
    return 2;
}

@Override
public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {
    switch(index)
    {
    case 0:
        info.type = PropertyInfo.STRING_CLASS;
        info.name = "message";
        break;
    case 1:
        info.type = PropertyInfo.OBJECT_TYPE;
        info.name = "clientNameList";
        break;
    default:
        break;
    }

}

@Override
public void setProperty(int index, Object value) {
    switch(index)
    {
    case 0:
        message = value.toString();
        break;
    case 1:
        clientNameList = (Client[]) value;
        break;
    default:
        break;
    }

}

Client.java仅包含Integer类型的clientId.

我坚持要简单地用XML获取响应,并使用任何XML Parser来解析更容易的响应.此外,我会坚持要使用ksoap2-android-assembly-2.5.4-jar-with-dependencies.jar您正在使用的那个已被弃用.

AndroidHttpTransport 正在被取代 HttpTransportSE

以下是如何通过XML获取响应,

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL, 100);
androidHttpTransport.debug=true; 
androidHttpTransport.call(SOAP_ACTION, envelope);
String response = androidHttpTransport.responseDump;
Log.d("Response in XML", response);

您将获得responseString中的响应,您可以使用SAX或任何其他XML解析器来解析它.
