Definicja

Namespace:

Montaż:

System.ServiceModel.dll

Tworzy wystawcę uwierzytelniającego tokenu zabezpieczającego na podstawie elementu SecurityTokenRequirement.

public:
 override System::IdentityModel::Selectors::SecurityTokenAuthenticator ^ CreateSecurityTokenAuthenticator(System::IdentityModel::Selectors::SecurityTokenRequirement ^ tokenRequirement, [Runtime::InteropServices::Out] System::IdentityModel::Selectors::SecurityTokenResolver ^ % outOfBandTokenResolver);

public override System.IdentityModel.Selectors.SecurityTokenAuthenticator CreateSecurityTokenAuthenticator(System.IdentityModel.Selectors.SecurityTokenRequirement tokenRequirement, out System.IdentityModel.Selectors.SecurityTokenResolver outOfBandTokenResolver);

override this.CreateSecurityTokenAuthenticator : System.IdentityModel.Selectors.SecurityTokenRequirement * SecurityTokenResolver -> System.IdentityModel.Selectors.SecurityTokenAuthenticator

Public Overrides Function CreateSecurityTokenAuthenticator (tokenRequirement As SecurityTokenRequirement, ByRef outOfBandTokenResolver As SecurityTokenResolver) As SecurityTokenAuthenticator

Parametry

tokenRequirement

SecurityTokenRequirement

Wymaganie dotyczące tokenu zabezpieczającego.

outOfBandTokenResolver

SecurityTokenResolver

Gdy ta metoda zwraca wartość , zawiera element SecurityTokenResolver. Ten parametr jest przekazywany jako niezainicjowany.

Zwraca

SecurityTokenAuthenticator

Wystawca uwierzytelniającego tokenu zabezpieczającego.

Wyjątki

ArgumentNullException

tokenRequirement to null.

NotSupportedException

Nie można utworzyć wystawcy uwierzytelniającego tokenu zabezpieczającego dla przekazanego tokenRequirement elementu .

Uwagi

Program rozpoznawania outOfBand tokenów może opcjonalnie zostać zwrócony przez metodę , która jest używana przez procesor zabezpieczeń WCF do rozpoznawania tokenów, które nie znajdują się w komunikacie PROTOKOŁU SOAP podczas przetwarzania zabezpieczeń. Element SecurityTokenAuthenticator zwracany przez tę metodę weryfikuje tokeny i wyodrębnia oświadczenia. Jeden SecurityTokenAuthenticator jest tworzony dla każdej klasy pochodzącej z ServiceModelSecurityTokenRequirementklasy .
