Question

我正在研究android项目，我正在尝试实现KSoap库。

我创建了一个托管C＃WCF soap服务的C＃Console应用程序，我试图让android与soap服务交谈。

以下是我的C＃WCF服务。

class SoapServer : ISoapInterface
    {
        public string testSoapFunction()
        {
            return "Hello World";
        }
    }

下面是肥皂界面

[ServiceContract]
    public interface ISoapInterface
    {
        [OperationContract]
        string testSoapFunction();
    }

以下是肥皂服务的启动方式

try
            {
                if (Environment.GetEnvironmentVariable("MONO_STRICT_MS_COMPLIANT") != "yes")
                {
                    Environment.SetEnvironmentVariable("MONO_STRICT_MS_COMPLIANT", "yes");
                }
                if (String.IsNullOrEmpty(soapServerUrl))
                {
                    string message = "Not starting Soap Server: URL or Port number is not set in config file";
                    library.logging(methodInfo, message);
                    library.setAlarm(message, CommonTasks.AlarmStatus.Medium, methodInfo);
                    return;
                }
                baseAddress = new Uri(soapServerUrl);
                host = new ServiceHost(soapHandlerType, baseAddress);
                BasicHttpBinding basicHttpBinding = new BasicHttpBinding();

                var meta = new ServiceMetadataBehavior()
                {
                    HttpGetEnabled = true,
                    HttpGetUrl = new Uri("", UriKind.Relative),
                };

                host.Description.Behaviors.Add(meta);

                var debugBehaviour = new ServiceDebugBehavior()
                {
                    HttpHelpPageEnabled = true,
                    HttpHelpPageUrl = new Uri("", UriKind.Relative),
                    IncludeExceptionDetailInFaults = true

                };

                ServiceEndpoint endpnt = host.AddServiceEndpoint(
                    soapManagerInterface,
                    basicHttpBinding,
                    "EmailServer",
                    new Uri("", UriKind.Relative));


                host.Description.Behaviors.Remove(typeof(ServiceDebugBehavior));
                host.Description.Behaviors.Add(debugBehaviour);
                host.Opened += new EventHandler(host_Opened);
                host.Faulted += new EventHandler(host_Faulted);
                host.Closed += new EventHandler(host_Closed);
                host.UnknownMessageReceived += new EventHandler<UnknownMessageReceivedEventArgs>(host_UnknownMessageReceived);
                host.Open();

以下是我通过android调用该服务的方式。

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final String soapAction = "http://tempuri.org/ISoapInterface/testSoapFunction";
        final String namespace = "http://tempuri.org/";
        final String methodName = "testSoapFunction";
        final String url = "http://192.168.1.69:8000/CritiMon";
        String resultData = "";

        new Thread(new Runnable() {

            @Override
            public void run() {
                String resultData = "";
                SoapSerializationEnvelope soapEnv = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                SoapObject request = new SoapObject(namespace, methodName);

                soapEnv.setOutputSoapObject(request);

                HttpTransportSE http = new HttpTransportSE(url);
                http.debug = true;

                try
                {
                    http.call(soapAction, soapEnv);

                    SoapObject result = (SoapObject)soapEnv.bodyOut;
                    if (result != null)
                    {
                        resultData = result.getProperty(0).toString();
                        Log.d("Soap Result", resultData);
                    }
                }
                catch (Exception ex)
                {
                    Log.e("Soap", ex.toString());
                }

            }
        }).start();

当我运行上面的代码时，我收到以下响应：

java.io.IOException：HTTP请求失败。 HTTP状态：500。

在soap服务器中，我还会触发包含

的未知消息接收事件处理程序

    XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://s

Answer 1

我终于找到了问题。

这是Web服务的一个问题，我认为这是我使用Android实现的一个问题。 soap接口中有一个类型，因此android调用没有找到该函数。

感谢您的帮助。

Answer 2

尝试添加以下内容

soapEnvelope.dotNet = true;

如果它不起作用，你可以发布你的WSDL文件吗？

[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples")]
public interface ICalculator
{
    [OperationContract]
    string testSoapFunction();
}

final String NAMESPACE = "http://Microsoft.ServiceModel.Samples";
final String SOAP_ACTION = "http://Microsoft.ServiceModel.Samples/ICalculator/testSoapFunction";
final String METHOD_NAME = "testSoapFunction";

httpTransport = new HttpTransportSE(url, 2000);


SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

httpTransport.debug = true;
//soapEnvelope.implicitTypes = true;
soapEnvelope.dotNet = true;
SoapObject soapReq = new SoapObject(NAMESPACE, METHOD_NAME);
soapEnvelope.setOutputSoapObject(soapReq);


try {
    httpTransport.call(SOAP_ACTION, soapEnvelope);
    Log.d("REQ" , httpTransport.requestDump);
    Log.d("RES" , httpTransport.responseDump);

    Object retObj = soapEnvelope.bodyIn;
    Log.d("TEST" , retObj.toString());
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (XmlPullParserException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Soap Req：

<v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
    <v:Header />
    <v:Body>
        <testSoapFunction xmlns="http://Microsoft.ServiceModel.Samples" id="o0" c:root="1" />
    </v:Body>
</v:Envelope>
