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

Parâmetros

tokenRequirement

SecurityTokenRequirement

O requisito de token de segurança.

outOfBandTokenResolver

SecurityTokenResolver

Quando este método retorna, ele contém um SecurityTokenResolver. Este parâmetro é passado não inicializado.

Retornos

SecurityTokenAuthenticator

O autenticador de token de segurança.

Exceções

ArgumentNullException

tokenRequirement é null.

NotSupportedException

Não é possível criar um autenticador de token de segurança para o tokenRequirement que foi passado.

Comentários

Opcionalmente outOfBand , um resolvedor de token pode ser retornado pelo método , que é usado pelo processador de segurança do WCF para resolver tokens que não estão na mensagem SOAP ao processar a segurança. O SecurityTokenAuthenticator retornado por esse método valida tokens e extrai declarações. Um SecurityTokenAuthenticator é criado para cada classe derivada de ServiceModelSecurityTokenRequirement.
