对象referans未使用kso​​ap2设置

Question

我正在开发一个带有soap服务的Android应用程序。但是，当我添加请求属性时，它不起作用。我错过了什么吗？

public class WebServiceCallerImp {

private static final String METHOD_NAME = "GetForexStocksandIndexesInfo";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ACTION = "http://tempuri.org/GetForexStocksandIndexesInfo";
private static final String URL = "http://mobileexam.veripark.com/mobileforeks/service.asmx";


public static String GetForex() {

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

    request.addProperty("IsIPAD", "true");
    request.addProperty("DeviceID", "test");
    request.addProperty("DeviceType", "ipad");
    request.addProperty("RequestKey", "%%UmVxdWVzdElzVmFsaWQyNzowNDoyMDE3IDEzOjEy%%");
    request.addProperty("Period", "Month");


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


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

    try {
        androidHttpTransport.call(SOAP_ACTION, envelope);
        SoapObject response = (SoapObject) envelope.getResponse();
        System.out.println("output: " + response.toString());
        return response.toString();
    } catch (Exception e) {
        System.out.println("@@@@: " + e.toString());

    }
    return "null";
}

Object reference not set to an instance of an object.    at Denizbank.IpadApplication.Integration.ForexIntegration.StocksandIndexes.GetForexStocksandIndexesInfo(StocksandIndexesRequest req)

at Denizbank.IpadApplication.Service.Service.GetForexStocksandIndexesInfo（StocksandIndexesRequest request）

肥皂请求

我在哪里犯错误？请帮帮我。

尝试这个我在我的项目中执行相同的代码并且没有错误。

SoapSerializationEnvelope soapEnvelope = null;
    soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    new MarshalBase64().register(soapEnvelope);
    soapEnvelope.implicitTypes = true;
    soapEnvelope.dotNet = true;
    SoapPrimitive result = null;

    soapEnvelope.setOutputSoapObject(request);

    HttpTransportSE aht = new HttpTransportSE(SERVER_URL, Const.HTTP_TIMEOUT);
    aht.debug = Const.LOG;

    try {
        Log.print("SOAP_ACTION::" + SOAP_ACTION, "SERVER_URL::" + SERVER_URL);
        Log.print("Request", "" + aht.requestDump);

        aht.call(SOAP_ACTION, soapEnvelope);
        Log.print("Response", "" + aht.responseDump);
        result = (SoapPrimitive) soapEnvelope.getResponse();

        Log.print("-----------Request :: ", "" + aht.requestDump);
        Log.print("=====================FINAL RESPONSE================");
        Log.print("RESPONSE :: " + result);
    } catch (UnknownHostException e) {
        if (Const.LOG) Log.print("UnknownHostException", "" + e);
        if (Const.LOG) Log.print("Exception in util", e.getMessage());
        soapEnvelope = null;
    } catch (IOException e) {
        if (Const.LOG) Log.print("IOException", "" + e);
        e.printStackTrace();
        soapEnvelope = null;
    } catch (XmlPullParserException e) {
        if (Const.LOG) Log.print("XmlPullParserException", "" + e);
        e.printStackTrace();
        soapEnvelope = null;
    } catch (OutOfMemoryError e) {
        if (Const.LOG) Log.print("OutOfMemoryError", "" + e);
        e.printStackTrace();
        soapEnvelope = null;
        result = null;
    } catch (Exception e) {
        if (Const.LOG) Log.print("Exception", "" + e);
        Log.print("Utils", e);
        e.printStackTrace();
        soapEnvelope = null;
    } finally {
        soapEnvelope = null;
        request = null;
        SOAP_ACTION = null;
        SERVER_URL = null;
        aht = null;
    }

Const.LOG值为true。
