Android kSOAP web服务问题

Question

我正在尝试通过 kSOAP（直接从 Google 下载并包含“.jar”）调用公共网络服务 (w3schools.com/webservices/tempconvert.asmx)。

这是我的代码：

// declarations

private static final String NAMESPACE = "http://tempuri.org/" ;
private static final String METHOD_NAME = "CelsiusToFahrenheit";
private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
private static final String URL = "http://216.128.29.26/webservices/tempconvert.asmx";

// code

try
{
   SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
   SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
   HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

   request.addProperty("Celsius", "32");
   envelope.setOutputSoapObject(request);
   androidHttpTransport.call(SOAP_ACTION, envelope);

   Object result = envelope.getResponse();
}
catch(Exception e)
{
   e.printStackTrace();
}

另外，“AndroidManifest.xml”包含访问互联网的权限：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

另外，我的 AVD 可以访问互联网（通过浏览器应用尝试过）。

有人可以帮帮我吗？我已经尝试了大约 6 个小时，但仍然失败。

谢谢！

Answer 1

问题是您正在主线程上进行网络调用，并且在 API 级别 12 中不再允许这样做。您只需将 ksoap2 调用移动到 AsyncTask 左右。顺便说一句，任何进行网络访问的东西都会出现这个问题。这是一个强制的严格模式检查。

Answer 2

好像你在做和我一样的教程。 http://www.vimeo.com/9633556

你好像不见了envelope.dotNet = true;

Answer 3

不完全是。我以前有过（尝试了至少 5 种不同的方法）。它没有帮助。这是 API 版本。我有 12 个。它没有用。我在某处发现 kSOAP 仅适用于 8 或更低版本。去图:)

我希望每个遇到这个问题的人都能在他们花太多时间使用 12 API 之前找到这个问题。

Answer 4

我刚刚使用 api 版本 10 和 ksoap2 尝试了我自己的代码（仅在尝试使用的 web 服务中有所不同），它仍然可以按预期工作。

            private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
            private static final String METHOD_NAME = "CelsiusToFahrenheit";
            private static final String NAMESPACE = "http://tempuri.org/";
            private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
            System.out.println("--==Creating SOAP object==--");
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            request.addProperty("Celsius", "32");
            System.out.println("--==Finished Creating SOAP object==--");

            System.out.println("--==Creating SOAP envelope==--");
            SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            soapEnvelope.dotNet = true;
            soapEnvelope.setOutputSoapObject(request);
            System.out.println("--==Finished Creating SOAP envelope==--");

            HttpTransportSE aht = new HttpTransportSE(URL);
            // aht.debug = true;

            try {
                System.out.println("--==Creating SOAP call==--");
                aht.call(SOAP_ACTION, soapEnvelope);
                System.out.println("test");

                SoapPrimitive response = (SoapPrimitive) soapEnvelope.getResponse();
                System.out.println(response.toString());
                tableData.addView(resultSoap);
                System.out.println("--==Finished Creating SOAP call==--");
            } catch (Exception e) {
                e.printStackTrace();
            }
            if (aht.debug == true) {
                System.out.println(aht.responseDump);
            }

package com.soap;

    import org.ksoap2.SoapEnvelope;
    import org.ksoap2.serialization.SoapObject;
    import org.ksoap2.serialization.SoapPrimitive;
    import org.ksoap2.serialization.SoapSerializationEnvelope;
    import org.ksoap2.transport.AndroidHttpTransport;

    import android.app.Activity;
    import android.os.Bundle;
    import android.util.Log;
    import android.widget.TextView;
    public class SoapsActivity extends Activity {
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit";
    private static final String METHOD_NAME = "CelsiusToFahrenheit";
    private static final String NAMESPACE = "http://tempuri.org/"; 
    private static final String URL = "http://www.w3schools.com/webservices/tempconvert.asmx";
    TextView tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tv = (TextView) findViewById(R.id.tvsoap);
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("Celsius", "32");
        SoapSerializationEnvelope evenlop = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        evenlop.dotNet = true;
        evenlop.setOutputSoapObject(request);
        AndroidHttpTransport aht = new AndroidHttpTransport(URL);
        try {
            aht.call(SOAP_ACTION, evenlop);
            SoapPrimitive resultString = (SoapPrimitive) evenlop.getResponse();
            tv.setText("ststus :" + resultString.toString());
        } catch (Exception e) {
            System.out.println(e.toString());
        }

    }
