Android Ksoap2 - 复杂类型（请求和响应）

标签： 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) {
     System.out.println(userRequest.getClientName());
     UserResponse UserResponse = new UserResponse();
     userResponse.setMessage("SUCCESS");
     return userResponse;
}

我将这些来自Android的网络服务称为

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());
        }

但是我在Logcat中收到的错误是“抛出异常：无法序列化：com.test.common.UserRequest ”。如何解决这个错误？这是使用复杂类型调用Web服务的正确方法吗？

我使用了KvmSerializable。我添加了一个数组bean变量 UserRequest.java中的private Client[] clientNameList = null;。

当我调用Web服务时，它在请求中正常工作。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。

更新了代码和wsdl

ImageProcessImpl.java 

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

ImageProcessDAO.java 

public static String sample(UserRequest userRequest) {
    System.out.println(userRequest.getClientName());
    UserResponse userResponse = new UserResponse();
    userResponse.setMessage(SUCCESS);
    Client[] clients = new Client[2];
    Client client = null;
    for(int i=0;i<2;i++)
    {
        client = new Client();
        client.setClientID(i+1);
        clients[i] = client;
    }
    userResponse.setClientNameList(clients);
    return userResponse;
}

        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);

2 个答案:

答案 0 :(得分：5)

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HttpTransportSE

取代

以下是如何使用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);

您将在response字符串中获得响应，您可以使用SAX或任何其他XML解析器来解析它。

答案 1 :(得分：2)

您的UserRequest类需要实现org.ksoap2.serialization.KvmSerializable。
