KSOAP2 webservice ilon100 smartserver

Question

我正在嘗試使用Android調用echelon smartserver的Web服務。 我需要替換與Android不兼容的jax-ws。我決定使用KSOAP2。

我想這樣，但沒有成功：

public class ConnectTest extends Activity implements OnClickListener { 
    Button SoapButton; 
private static final String NAMESPACE = "http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/wsdl/"; 
    private static String URL = "http://192.168.100.247/WSDL/v4.0/iLON100.wsdl"; 
    private static final String METHOD_NAME = "List"; 
    private static final String SOAP_ACTION = "http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/wsdl/List"; 

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
PropertyInfo propInfo = new PropertyInfo(); 
propInfo.name = "iLonItem"; 
request.addProperty("<xSelect>//Item[@xsi:type=\"Item_Cfg\"]</xSelect>",propInfo); 
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11); 
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
try 
      { 
       androidHttpTransport.call(SOAP_ACTION, envelope); 
       SoapPrimitive resultsRequestSOAP = (SoapPrimitive) envelope 
         .getResponse(); 
       SoapResponse = resultsRequestSOAP.toString(); 
       System.out.println("SOAP" + SoapResponse); 

      } catch (Exception e) 
      { 

       Log.e("Error", "pb IO", e); 
       SoapResponse = "error connection"; 
      } 

      return SoapResponse; 

它結束了以下控制檯錯誤：

java.lang.RuntimeException: Cannot serialize: iLonItem : (not set) 

我應該怎麼做來糾正使用SOAP發送下面的消息？當然使用KSOAP2。

<List xmlns="http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/"> 
<iLonItem> 
<xSelect>//Item[@xsi:type=\"Item_Cfg\"]</xSelect> 
</iLonItem> 
</List> 

請幫忙。 謝謝！

Answer 1

我相信有幾件事情需要改變。

首先，預期的命名空間是"http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/"

這是在這行代碼中找到您所提供

<List xmlns="http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/">

第二，我相信你有屬性切換左右。 iLonItem是屬性名稱，應首先去在request呼叫這樣

request.addProperty("iLonItem","<xSelect>//Item[@xsi:type=\"Item_Cfg\"]</xSelect>"); 

至於價值，我不知道什麼是「//項目[@xsi：類型= \」 Item_Cfg \「]」手段，但希望它能認識到這個要求，並且做它應該做的事情。
