Do tej pory korzystałem z usług sieci Web i działało dobrze. Dodałem nową usługę WCF.
Dzwonię do usług za pomocą jQuery. W ten sposób użyłem jQuery zużywają usługi sieci Web:Zużywanie usługi WCF przy użyciu jQuery
$.ajax({
dataType: 'json',
processData: false,
type: 'POST',
contentType: "application/json",
url: url,
context: s.context,
data: JSON.stringify(s.data),
error: function (xhr, textStatus, errorThrown) {
if (s.error != null) {
s.error(xhr, textStatus, errorThrown);
}
if (s.error_addition != null) {
s.error_addition(xhr, textStatus, errorThrown);
}
},
success: function (data, textStatus, xhr) {
s.success(data.d, textStatus, xhr);
subscriber.setDone(data.d);
}
});
I nie można zastosować tej metody w celu wykorzystania usługi WCF. Tak zdefiniowana usługa WCF:
[ServiceContract]
public interface ISystemService
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
Reason[] GetCallReasons();
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class SystemService : SimTaskService, ISystemService
{
public Reason[] GetCallReasons()
{
//...
}
}
Nie dodałem nic do konfiguracji sieci dla usługi WCF.
Korzystanie Skrzypek, to nagłówki odpowiedzi:
HTTP/1.1 415 Cannot process the message because the content type 'application/x-www-form-urlencoded' was not the expected type 'text/xml; charset=utf-8'.
Tu jest mój plik web.config:

Czy ktoś wie jak to naprawić?
Powstaje pytanie, dlaczego nie można dostać formularz posta zamiast postu json z typem treści 'application/json'. Również dlaczego publikujesz dane, gdy twoja operacja nie oczekuje żadnych parametrów wejściowych? –
@ Ladislav Mrnka: Jest to metoda ogólna. dane faktycznie są pustym obiektem. Co to jest "post json"? – Naor
@Naro: Kod pocztowy twojego web.config –
