Android 与 WCF Web 服务使用 ksoap2 - 错误 SoapFault - 故障代码 : 'a:InternalServiceFault'

Question

我做了一个简单的项目来使用 ksoap2 调用 wcf web 服务。但是当它调用 envelope.getResponse();它给出了错误的说法

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 或配置行为)以便将异常信息发送回客户端，或者根据 Microsoft .NET Framework 3.0 SDK 文档打开跟踪并检查服务器跟踪日志。 faultactor:'null' 详细信息:null

            String inputxml = "<?xml version="+"\""+"1.0"+"\""+" encoding="+"\""+"utf-8"+"\""+" ?>" +"<MOB> \n  <PIN>0000</PIN> \n  <LOGINID>TEST</LOGINID> \n  <PNUMBER>112233</pNUMBER> \n  <REQUESTID>LoginVal</REQUESTID> \n </MOB>";

            request.addAttribute("strInputXML", inputxml);
            request.addAttribute("strOutputXML","");

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

             HttpTransportSE androidHttpTransport = new HttpTransportSE(strURL);
             androidHttpTransport.call(strSOAP_ACTION, envelope);
             SoapPrimitive result = (SoapPrimitive)envelope.getResponse();

             String resultData = result.toString();
             sb.append(resultData + "\n");
         }
         catch(Exception e)
         {
             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(bind)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;
}

希望我的代码能帮到你 :)。它以 100% 的速度工作
