ServiceCredentialsSecurityTokenManager.CreateSecurityTokenAuthenticator Metoda

Definice

Vytvoří ověřovací token zabezpečení na základě objektu 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

Požadavek na token zabezpečení.

outOfBandTokenResolver
SecurityTokenResolver

Když tato metoda vrátí hodnotu , obsahuje SecurityTokenResolver. Tento parametr se předává neinicializovaný.

Návraty

Ověřovací token zabezpečení.

Výjimky

tokenRequirement je null.

Pro předaný token zabezpečení nelze vytvořit tokenRequirement ověřovací token zabezpečení.

Poznámky

Překladač outOfBand tokenů může být volitelně vrácen metodou , kterou používá procesor zabezpečení WCF k překladu tokenů, které nejsou ve zprávě SOAP při zpracování zabezpečení. Metoda vrácená SecurityTokenAuthenticator touto metodou ověřuje tokeny a extrahuje deklarace identity. Pro každou třídu odvozenou z ServiceModelSecurityTokenRequirementse vytvoří jedna SecurityTokenAuthenticator třída.
