Ksoap将空变量发送到WCF服务

Question

每次我尝试从android studio中的单元测试向WCF服务发送变量时，服务都不会得到它，它只是开始运行该方法并返回false（参见下面的代码）。奇怪的是，我可以使用不需要变量的方法从服务中获取数据。

这是服务代码：

 public bool ValidarAdm(string jsonString)
    {
        if (jsonString != null)
        {
            Negocio.Administrador a = Negocio.Administrador.Deserializar(jsonString);
            return a.ValidarUsuario();
        }
        else
        {
            return false;
        }
    }

这是Android studio中的连接类

 private String soapAction;
private String nameSpace;
private String methodName;
private String url;
public Connection(String soapAction, String nameSpace, String methodName, String url) {
    this.soapAction = soapAction;
    this.nameSpace = nameSpace;
    this.methodName = methodName;
    this.url = url;
}

 public String getData(String parameter, String value)
 {
     SoapObject request = new SoapObject(nameSpace,methodName);


     request.addProperty(parameter,value);
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
     envelope.dotNet=true;
     envelope.setOutputSoapObject(request);
     HttpTransportSE androidHttpTrasporSE= new HttpTransportSE(url);
     try {
         androidHttpTrasporSE.call(soapAction,envelope);
     } catch (IOException e)
     {
         e.printStackTrace();
     } catch (XmlPullParserException e)
     {
         e.printStackTrace();
     }
     SoapObject result = (SoapObject)envelope.bodyIn;
     String s ="";
     if(result!=null)
     {


         s= result.getProperty(0).toString();
     }
     return s;
 }

和单元测试中的代码

  public void test_ValidarAdmin_isCorrect()
{

    String soapAction="localhost/IEcommerceService/ValidarAdm";
    String nameSpace="localhost/";
    String methodName="ValidarAdm";
    String url="http://localhost:65080/EcommerceService.svc?Wsdl";

    Connection con = new Connection(soapAction,nameSpace,methodName,url);
    Admin ad = new Admin("a","a",1);
    Gson g = new Gson();
    String jsonString= g.toJson(ad);

    String a ="";

    System.out.println(methodName);

    System.out.println(jsonString);
    a=con.getData(methodName,jsonString);
    System.out.println(a);


}
