Android .Net 网络服务 使用 ksoap2-android-2.6.2.jar，字符串参数变为 nul

Question

我在测试Android应用程序尝试传递字符串参数时遇到问题，我希望返回参数的值，这是我的Web服务代码：

[WebService(Namespace = "http://xxx.xxx.x.xxx:8080/root")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {
        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }
        [WebMethod]
        public String SayHello(String name)
        {
                return name;
        }
    }
}

此 Web 服务托管在我的本地 PC IIS 上这是我的安卓肥皂电话：

public class CallSoap {
    // Lever one
    public final String SOAP_SAY_HELLO = "http://xxx.xxx.x.xxx:8080/root/SayHello";
    // Lever two operation
    public final String SAY_HELLO_OPERATION = "SayHello";
    // Lever four Soap target namespace
    public final String WSDL_TARGET_NAMESPACE = "http://xxx.xxx.x.xxx:8080/root";
    // Lever four Soap address
    public final String SOAP_ADDRESS = "http://xxx.xxx.x.xxx:8080/Service1.asmx";
    // Call say hello Method
    public String getHello(String nameVal) {
        String resp = new String();
        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
                SAY_HELLO_OPERATION);

        request.addProperty("name", "Test");
        SoapSerializationEnvelope envelop = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelop.dotNet = false;
        envelop.setOutputSoapObject(request);
        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
        Log.d("HTTP  REQUEST", "HTTP REQUEST:n" + httpTransport.requestDump);
        Log.d("HTTP  RESPONSE", "HTTP RESPONSE:n" + httpTransport.responseDump);
        Object response1 = new Object();
        try {
            httpTransport
                    .setXmlVersionTag("<?xml version="1.0" encoding="UTF-8"?>");
            httpTransport.call(SOAP_SAY_HELLO, envelop);
            if (envelop.bodyIn instanceof SoapObject) { // SoapObject = SUCCESS
                SoapObject soapObject = (SoapObject) envelop.bodyIn;
                response1 = envelop.getResponse();
            } else if (envelop.bodyIn instanceof SoapFault) { // SoapFault =
                                                                // FAILURE
                SoapFault soapFault = (SoapFault) envelop.bodyIn;
                response1 = soapFault.getClass();
                throw new Exception(soapFault.getMessage());
            }
            return resp;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return resp;
    }
}

我得到空值作为返回值，如果我检查肥皂信封，我可以在数据包中看到我的参数。 我没有想法 发送了参数发生了什么。

请任何可以帮助我确定错误的人，提前感谢

我发现出了什么问题;当我将 Web 服务托管到本地 IIS 时，我必须添加包含托管 Web 服务文件的文件夹的安全性，在我的代码中，我不得不更改envelope.dotNet=true而不是envelope.dotNet=false仅此而已。
