SOAP call from Android with KSoap2 to .net WebServer

Question

Good day everyone.

I'm trying to do a SOAP call to a .net WebServer running locally, but I think I'm missing something. The Android code seems fine to me. Maybe the SOAP request is wrong...

This is what the webserver gives for the method I'm trying to call:

POST /WebAvanza/WebAvanzaInterface.asmx HTTP/1.1
Host: localhost
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <InitTransazione xmlns="http://tempuri.org/">
      <ip>string</ip>
      <codice>string</codice>
    </InitTransazione>
  </soap12:Body>
</soap12:Envelope>

and this is what i wrote so far:

private String InitTransaction(String command){
        String NAMESPACE = "http://tempuri.org/";
        String METHOD_NAME = "InitTransazione";
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("ip", ipAddress);
        request.addProperty("codice", command);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransport = new HttpTransportSE(URL);
        httpTransport.debug = true;

        String SOAP_ACTION = NAMESPACE + METHOD_NAME;

        Object result = null;
        try {
            httpTransport.call(SOAP_ACTION, envelope);
            result = envelope.getResponse();
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }

        return String.valueOf(result);
    }

URL is http://192.168.168.24/WebAvanza/WebAvanzaInterface.asmx, the address refers to the machine where the server is running.

I only get an exception after executing httpTransport.call.

This is the StackTrace (if anybosy needs it)

Answer 1

Checking your code I think the main problem is because you are not executing Okhttpclient in async thread.

I think the problem should be solved if you run the code using enqueue method of the Okhttpclient.

client.newCall(request).enqueue(new Callback() {
      @Override public void onFailure(Call call, IOException e) {
        //Exception here
        }

      @Override public void onResponse(Call call, Response response) throws IOException {
        try (ResponseBody responseBody = response.body()) {
           /*
           * Handle your response here :
           * Do whatever you want if the response.isSuccesful or not
           */ 
        }
    });

I hope it helps you.

I found out that the problem was in the server and the code was fine... Goddamn I spent almost 5 hours behind this .__.
