【问题描述】：

我在测试 Android 应用时遇到问题，尝试传递字符串参数，我希望返回参数的值，这是我的 WebService 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 WebService 托管在我的本地 PC IIS 上这是我的 Android 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。我不知道发送的参数发生了什么。

请任何可以帮助我确定哪里出错的人，提前谢谢

【解决方案1】：

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，并且在我的代码中我必须更改 envelope.dotNet=true 而不是 envelope.dotNet=false 就是这样。
