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

Parámetros

tokenRequirement

SecurityTokenRequirement

El requisito del token de seguridad.

outOfBandTokenResolver

SecurityTokenResolver

Cuando este método se devuelve, contiene SecurityTokenResolver. Este parámetro se pasa sin inicializar.

Devoluciones

SecurityTokenAuthenticator

Comentarios

Opcionalmente, el método puede devolver un outOfBand solucionador de tokens, que usa el procesador de seguridad WCF para resolver los tokens que no están en el mensaje SOAP al procesar la seguridad. La SecurityTokenAuthenticator devuelta por este método valida tokens y extrae notificaciones. Un SecurityTokenAuthenticator se crea para cada clase derivada de ServiceModelSecurityTokenRequirement.
