Question

我在

处收到序列化错误

androidHttpTransport.call(SOAP_ACTION, envelope);

这是 WebService Class

的完整代码

public class WebserviceCall extends AsyncTask<String, Void, Void> {


    String result = "";

    HttpTransportSE androidHttpTransport;

    public WebserviceCall() {
        // TODO Auto-generated constructor stub
    }

    @Override
    protected Void doInBackground(String... urls) {

        try {
            SOAP_ACTION = namespace + METHOD_NAME;

            // Adding values to request object
            request = new SoapObject(namespace, METHOD_NAME);

            // Adding Double value to request object
            PropertyInfo weightProp = new PropertyInfo();
            weightProp.setName("Weight");
            double w = Double.parseDouble(urls[0]);
            weightProp.setValue(w);
            weightProp.setType(double.class);
            request.addProperty(weightProp);

            // Adding String value to request object
            request.addProperty("FromUnit", "" + urls[1]);
            request.addProperty("ToUnit", "" + urls[2]);

            envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

            // You can comment that line if your web service is not .NET
            // one.
            envelope.dotNet = true;

            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
            androidHttpTransport.debug = true;

            try {

                // SOAP calling webservice
                androidHttpTransport.call(SOAP_ACTION, envelope);

                // Got Webservice response
                result = envelope.getResponse().toString();

            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void r) {
        setResult(result);
    }
}

Answer 1

试试这个，拨打电话后，请添加以下行：

SoapPrimitive response = (SoapPrimitive) envelope.getResponse();    
String resString=response.toString();

Answer 2

没有必要将权重解析为double。我对我的代码进行了以下更改，现在它正在运行。

PropertyInfo weightProp =new PropertyInfo();
        weightProp.setName("Weight");
        weightProp.setValue(urls[0]);
        weightProp.setType(double.class);
        request.addProperty(weightProp);
