使用 ksoap2 的带有 WCF Web 服务的 Android - 错误 SoapFault - 故障代码：'a:InternalServiceFault'

Question

我做了一个简单的项目，使用 ksoap2 调用 wcf web 服务。但是当它调用信封.getResponse();它给出了错误提示

错误： SoapFault - faultcode: 'a:InternalServiceFault' faultstring: '由于内部错误，服务器无法处理请求。有关错误的更多信息，请在服务器上打开 IncludeExceptionDetailInFaults（来自 ServiceBehaviorAttribute 或来自配置行为）以便将异常信息发送回客户端，或根据 Microsoft .NET Framework 3.0 SDK 文档打开跟踪并检查服务器跟踪日志。 faultactor: 'null' 细节: null

             sb.append("Error:\n" + e.getMessage() + "\n");
         }

}

这里我想这样发送请求

<?xml version="1.0" encoding="utf-8" ?> 
<PhoneData>
<PINNO>0000</PINNO>
<LOGINID>HELLO</LOGINID>
<PASSWORD>1234</PASSWORD>
<REQID>0</REQID>
</PhoneData>

我的响应 XML 应该是

<?xml version="1.0" encoding="utf-8" ?> 
<PhoneData>
<OTA>1234</OTA>
</PhoneData>

我发布了使用 WCF 的工作代码（WCF 的绑定必须是 basicHttpBinding！）：

private static final String NAMESPACE = "http://tempuri.org/";
private static String URL="your url";

private static final String SOAP_ACTION_VALIDATION = "IValidateUser_wcf/ValidateUser";
private static final String VALIDATION_METHOD = "ValidateUser";

public boolean validateUser_WCF(String username, String password){

    SoapSerializationEnvelope envelope = null;
    SoapObject request = null;
    HttpTransportSE httpTransportSE = null;

    try {
        request = new SoapObject(NAMESPACE, VALIDATION_METHOD);
        request.addProperty("username", username);
        request.addProperty("password", password);

        envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);

            //////////////////////////////                               
            // here you can add a HEADER element if you want
        Element[] header = new Element[1];  

        header[0] = new Element().createElement(NAMESPACE_INFOCAD, "a1");                
        header[0].addChild(Node.TEXT, "HeaderTextContent");

        envelope.headerOut = header;
            //////////////////////////////                               

        httpTransportSE = new HttpTransportSE(URL+VALIDATION_URI, 10*10000); // second parameter is timeout
        httpTransportSE.debug = true;
        httpTransportSE.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
        httpTransportSE.call(NAMESPACE+SOAP_ACTION_VALIDATION, envelope);

            // if response is a simple text result, you can call SoapPrimitive, if not, you have to call SoapObject result and navigate in response's tree like an xml file
        SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

        //To get the data.
        String textResult = result.toString();
        Log.i("textResult", textResult); 

                    return true;

    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }finally{
                 // here you can see in LOG what is request you send and what is response received
                Log.i(getClass().getSimpleName(),"requestDump : "+httpTransportSE.requestDump);
                Log.i(getClass().getSimpleName(),"responseDump : "+httpTransportSE.responseDump);
    }

    return false;
}

希望我的代码可以帮助你:)。它工作在 100%

我认为你应该研究一下名为 FaultContract 的东西。如果服务抛出异常，错误消息将永远不会到达客户端。所以这就是FaultContract 的来源。比如说，调用服务会导致服务异常，客户端应该如何知道捕获的错误？

这是一个关于如何实现 FaulContract 的示例：

//An interface for your service
[ServiceContract()]
    public interface IMultiply
    {
        [OperationContract()]
        int Multiply(int number1, int number2);
    }

你的“服务类”中的方法应该是implement这个interface

//Service implementation

public  class DoSomeMath: IMultiply
{
   public int Multiply(int number1, int number2)
   {
     try 
     {
        int k = number1 * number2;
     } 
     catch (Exception e)
     {
       MyFaultException theFault = new MyFaultException();
       theFault.Reason = "Some Error " + e.Message.ToString();
       throw new FaultException<MyFaultException>(theFault);
     }      
     return k;     
   }
}

在客户端，您现在可以捕获异常。如需进一步阅读，我建议您阅读：

Exception Handling in WCF using Fault Contract

我希望这将为您指明正确的方向。

对于 android Emulator 使用这个 ip:10.0.2.2 否则它将无法工作！！ 私有最终字符串 SOAP_URL="http://10.0.2.2:15398/Service1.svc";
