如何使用kso​​ap2使用Web服务

Question

我正在尝试使用Web服务2天，但我失败了。这是我的代码：

String SOAP_ACTION = "urn:WsTestIntf-IWsTest#Test101";
                String METHOD_NAME = "Test101";
                String NAMESPACE = "urn:WsTestIntf-IWsTest";
                String URL = "http://wsig.127.cc:8465/WsTemp.dll/wsdl/IWsTest";

                String strTemp;

                SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                envelope.setOutputSoapObject(request);
                HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
                try
                {
                    androidHttpTransport.call(SOAP_ACTION, envelope);
                    SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;

                    strTemp = resultsRequestSOAP.toString();


                } catch (Exception e) {
                    strTemp = "Error : " + e.getMessage();
                }

                Toast.makeText(getBaseContext(), strTemp, Toast.LENGTH_SHORT).show();

它出了什么问题？我已将INTERNET权限放入我的清单中。 Web服务是用Delphi编写的。

我用ksoap2度过了很长时间，但是有一个正常工作的客户端代码..希望它有所帮助......

注意： 它会重试3次，如果你愿意，你可以删除它。

        return xml == "" ? "Something Went Wrong Please Try Again!" : xml;
