我想使用 KSOAP2 创建 Web 服务的连接，我已经完成了代码并且它出现了错误，所以请建议我在哪里做错了。我还需要一些关于 Web 服务方面的帮助，什么是命名空间，方法我们调用，soap_action，url 以及一些关于我们在 web 服务中使用的方法。我搜索了很多，但没有找到任何关于 web 服务的完整描述
public class Web_ServicesActivity extends Activity {
private static String SOAP_ACTION = "http://service.fun2shoot.com/getLive";
private static String NAMESPACE = "http://service.fun2shoot.com/";
private static String METHOD_NAME = "getLive";
private static String URL = "http://119.82.75.91:8084/Fun2Shoot-WebService/Fun2ShootAndroid?wsdl";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out
.println("After mail******************************************");
// Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
System.out.println("****************After Request call");
// Use this to add parameters
// request.addProperty("Parameter","Value");
// Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
// Needed to make the internet call
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
// this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
} catch (Exception e) {
e.printStackTrace();
}
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject) envelope.bodyIn;
if (result != null) {
TextView t = (TextView) this.findViewById(R.id.tv);
System.out
.println("***************************************Inside null condition");
// Get the first property and change the label text
t.setText("SOAP response:\n\n" + result.getProperty(0).toString());
}
}
}
