如何通过 kSOAP 2 从 .net Web 服务获取数据

Question

我正在使用 kSoap2 从 WS 获取数据。但我得到的输出是字符串“Error”，而不是值“89.6”。

谁能告诉我下面的代码哪里出了问题？

package net.manoj.MytestServices;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class Main extends Activity { 
private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
private static final String METHOD_NAME = "CelsiusToFahrenheit";
private static final String NAMESPACE = "http://www.tempuri.org/";
// private static final String URL = "http://216.128.29.26/webservices/tempconvert.asmx";
private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx"; 
   TextView tv;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    tv = (TextView) findViewById(R.id.textView1);
    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
    Request.addProperty("Celsius", "32");

    SoapSerializationEnvelope SoapEnvelop = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    SoapEnvelop.dotNet = true;
    SoapEnvelop.setOutputSoapObject(Request);
    HttpTransportSE abt = new HttpTransportSE(URL);
    abt.debug = true;

    try {
        abt.call(SOAP_ACTION, SoapEnvelop);
        //SoapPrimitive resultstring = (SoapPrimitive) SoapEnvelop.getResponse();
        SoapObject result = (SoapObject) SoapEnvelop.getResponse();
        Object f = result.toString();
        tv.setText("States : " + f);

      } catch (Exception e) {
        e.printStackTrace();
    }
  }
    }

我没有得到任何例外。有人可以帮我解决这个问题吗？

Answer 1

你添加了 KSOAP2 jar 文件吗？

下载此文件并将其添加到您的项目中。

ksoap2-android- assembly-2.5.4-jar-with-dependency.jar

如果此后出现任何错误，请告诉我。

Answer 2

从以下链接下载 KSOAP2 jar 文件：

https://oss.sonatype.org/content/repositories/ksoap2-android-releases/com/google/code/ksoap2-android/ksoap2-android- assembly/2.6.0/ksoap2-android- assembly-2.6 .0-jar-with-dependency.jar

将下载的 jar 文件添加到项目的 libs 文件夹中。
