我需要帮助。
我需要显示用户列表。
我的web服务呼叫是：
/**
* llistar usuaris
* @return
* - una llista amb tots els usuaris
* Si no hi ha usuaris la llista estara blanca.
* - en altres casos retorna WebServiceCalls.ERROR_CRIDA
*/
public SoapObject consultarUsuaris(String tipusUsuari, String authId){
final String metode = "consultarUsuaris";
SoapObject respostaSoap = null;
try{
//Preparem els arguments del mètode compovarLogin
Map<String,String> args = new HashMap<>();
args.put("tipusUsuari",tipusUsuari);
args.put("authId",authId);
//Fem la crida al mètode per obtenir-ne la resposta
respostaSoap = usarWebService(metode,args);
//Retornem el valor de "authId"
// return respostaSoap.getPrimitiveProperty("authId").toString();
// System.out.println(respostaSoap.getPrimitiveProperty("authId").toString());
respostaSoap.getPrimitiveProperty("nom").toString();
}
catch(Exception ex){
ex.printStackTrace();
}
return respostaSoap;
}
我的代码是：（这是我提取信息的地方。）
public Object mostrarUsuaris() {
//Fem trucada a l'altre clase per recuperar el valor de authID
GamificacIOC ioc = new GamificacIOC();
//AuthId
Object authId = ioc.authId;
Object nom = null;
//Truquem la clase on tenim el metode de alta usuari
WebServiceCalls calls = new WebServiceCalls();
SoapObject resposta = calls.consultarUsuaris(WebServiceCalls.TIPUS_USUARI_ALUMNE, authId.toString());
if (resposta == null)
{
JOptionPane.showMessageDialog(null, "Error falten dades");
}
else
{
//Si els buttons son plens verifica que sigui correcte
authId= resposta.getPrimitiveProperty("authId");
// nom = resposta.getPrimitiveProperty("nom");
//authId ens dona el resultat que volem pasar per saber el tipus User
System.out.println(authId + " nom " +nom);
//Enviem l'authId per poder saber que usuari es...
String resposta2 = calls.tipusUsuari(authId.toString());
System.out.println(authId);
}
return authId;
} }
我需要提取所有用户的姓名。
mi SOAP UI请求为：
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> <S:Body>
<ns2:consultarUsuarisResponse xmlns:ns2="http://webservices.gamificacioc.com/">
<llistarUsuaris>

请帮助我T_T 它给了我错误，但没有显示任何内容.....
我对webService的了解很少。我有打通的电话。但这不是。
谢谢!!!!!!!!!!!!!!!!!!!!!!!!!!!
添加其他信息：
private SoapObject usarWebService(String metode, Map<String,String> args)
throws IOException, HttpResponseException, XmlPullParserException{
SoapObject peticio = crearPeticio(metode,args);
SoapSerializationEnvelope embolcall = obtenirEmbolcallPeticio(peticio);
return cridaWebService(metode,embolcall);
}
private SoapObject cridaWebService(String metode, SoapSerializationEnvelope envelope)
throws IOException, HttpResponseException, XmlPullParserException{
//Creem l'objecte per fer la crida al web service
HttpTransportSE httpTransportSE = new HttpTransportSE(GIOC_WEB_SERVICES);
//Fem la crida
httpTransportSE.call(metode, envelope);
return (SoapObject) envelope.getResponse();
}
这是错误：
