Question

我正在使用KSOAP2库来调用ASP.NET Web服务。我没有收到任何错误，但我也没有得到任何回应任何想法来解决这个问题。

以下是我的代码。我只是调用helloworld默认方法返回一个字符串。

    public class MainActivity extends Activity {

        private final String NAMESPACE = "http://tempuri.org/";
        private final String URL = "http://(ip)/TrialService.asmx";
        private final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
        private final String METHOD_NAME = "HelloWorld";
        TextView t1;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            t1 = (TextView) findViewById(R.id.textView1);

            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                        .permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
            try {
                androidHttpTransport.call(SOAP_ACTION, envelope);
                String receivedInt = (String) envelope.getResponse();
                t1.setText(receivedInt);
                setContentView(t1);
            } catch (Exception e) {
                t1.setText("error");
            }
        }
    }

Answer 1

首先启动调试，以便您可以看到要发送到服务器的soap信封的内容，您可以通过添加来执行此操作（请参阅注释部分）：

HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;//ADD THIS
try {
     androidHttpTransport.call(SOAP_ACTION, envelope);
     //ADD THESE 2
     //Important Outputs to check how the request/Response looks like.. Check them in Logcat to find these outputs
     System.out.println("requestDump is :"+androidHttpTransport.requestDump);//ADDED
     System.out.println("responseDump is :"+androidHttpTransport.responseDump);//ADDED

     String receivedInt = (String) envelope.getResponse();
     t1.setText(receivedInt);
     setContentView(t1);
} catch (Exception e) {
        t1.setText("error");
}

现在您可以看到发送到您服务器的soap信封，检查它是否准确。（您可以使用SoapUI.）

等程序将其与桌面发送的信封进行比较

下一步：

您必须提供更多详细信息，以便我们更好地为您提供帮助：提供相关WSDL部件的副本。
确保您使用的准确值为：NAMESPACE，METHOD_NAME，网址，SOAP_ACTION
如果这是一个测试项目并且您可以访问服务器，您可以将其作为奖励来检查服务器上发生的情况你发送请求。
