android - 使用 kSoap2 在 android 中访问 WebService

Question

自过去三天以来，我一直在挖掘以找出使用 kSoap2 访问 Web 服务的适当方法。现在我可以访问网络服务了，但我需要知道我是否遵循了正确的方法或者我已经超出了标准。我已经发布了完整的代码和输出，如果我在任何地方出错，请纠正我。

// WebServiceConsumer.java



 public SoapObject soap(String METHOD_NAME, String SOAP_ACTION, String NAMESPACE, String URL) throws IOException, XmlPullParserException {

 /** Construction of the SoapObject */
 SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); //set up request
 /** passing the values in to the webservice*/
 request.addProperty("iTopN", "0"); //variable name, value. got the variable name, from the wsdl file!

 /** Creation of the SoapEnvelope with the appropriate version*/
 SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); //put all required data into a soap envelope
 envelope.dotNet = true;
 envelope.setOutputSoapObject(request); //prepare request
 /** Creating AndroidTransport for passing the request to the URL where the service is located*/
 AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL); 
 httpTransport.debug = true; //this is optional, use it if you don't want to use a packet sniffer to check what the sent message was (httpTransport.requestDump)
 httpTransport.call(SOAP_ACTION, envelope); //send request
 SoapObject result =(SoapObject)envelope.bodyIn; //get response
 return result;
 }

 public void callService() {
 try{
 SoapObject result = soap(METHOD_NAME, SOAP_ACTION, NAMESPACE, URL);
 Log.i(TAG,"Result:" + result);
 try {
 // FootballScoreParser.parseBusinessObject(result.getProperty(0).toString(), footballscore);
 SoapObject logObject = (SoapObject) result.getProperty(0);
 Log.i(TAG,"LogObject : " + logObject);
 for(int i = 0; i < 10 ; i++) {
 SoapObject logger = (SoapObject) logObject.getProperty(i);
 // Log.i(TAG,"Name : " + logger.getProperty("sName"));
 // Log.i(TAG,"Goals : "+ logger.getProperty("iGoals"));

 /** Appending the sName,iGoals in to ArrayList name */
 name.add((String)logger.getProperty("sName").toString());
 goals.add((String) logger.getProperty("iGoals").toString());
 country.add((String) logger.getProperty("sCountry").toString());
 flag.add((String) logger.getProperty("sFlag").toString());

 /** Converting the ArrayList into the Object Array*/
 objName = name.toArray();
 objGoals = goals.toArray();
 objCountry = country.toArray();
 objFlags = flag.toArray();
 }
 for(int j = 0; j < objName.length; j++){
 Log.i(TAG,"Name ["+ j + "]=" + objName[j].toString() + "," + "Goals ["+ j + "]=" + objGoals[j].toString()+ "," + "Country[" + j + "]=" + objCountry[j].toString() + "," +"Flag[" +j+ "]=" + objFlags[j].toString());

 }
 }
 catch(Exception err){
 Log.i(TAG, "" + err);
 }


 }
 catch(Exception err){
 Log.i(TAG,""+ err);
 }
 /* catch(NumberFormatException err){
 err.printStackTrace(); 
 }
 catch(IllegalArgumentException err){
 err.printStackTrace();
 }
 catch(IllegalAccessException err){
 err.printStackTrace();
 }
 catch(InstantiationException err){
 err.printStackTrace();
 }*/
 //}


// FootBallScrorerActivity.java

package com.project.mobile.FootballScorers;

import android.app.Activity;
import android.os.Bundle;

public class FootbalScorerActivity extends Activity {
WebServiceConsumer webconsumer;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    webconsumer = new WebServiceConsumer();
    webconsumer.callService();

}
}

根据输出，在我看来您的 Web 服务返回 LogObject，这意味着它是一个复杂对象。要使用复杂对象，您也应该在 Android 中实现相同的类，并实现 KSOAP Marshal 接口(interface)。之后，您应该向该类注册 Add mapping，以便 KSOAP 知道如何处理接收到的对象。
