ServiceCredentialsSecurityTokenManager.CreateSecurityTokenAuthenticator Metod

Definition

Namnområde:
System.ServiceModel.Security
Sammansättning:
System.ServiceModel.dll

Skapar en säkerhetstokenautentisering baserat på 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

Parametrar

tokenRequirement
SecurityTokenRequirement

Krav för säkerhetstoken.

outOfBandTokenResolver
SecurityTokenResolver

När den här metoden returnerar innehåller en SecurityTokenResolver. Den här parametern skickas oinitierad.

Returer

SecurityTokenAuthenticator

Autentisering av säkerhetstoken.

Undantag

ArgumentNullException

tokenRequirement är null.

NotSupportedException

Det går inte att skapa en autentisering för säkerhetstoken för den tokenRequirement som skickades in.

Exempel

    {
        // Return your implementation of the SecurityTokenProvider based on the
        // tokenRequirement argument.
        SecurityTokenAuthenticator result;

Kommentarer

En outOfBand tokenlösare kan eventuellt returneras med metoden, som används av WCF-säkerhetsprocessorn för att lösa token som inte finns i SOAP-meddelandet vid bearbetning av säkerhet. Det SecurityTokenAuthenticator som returneras av den här metoden validerar token och extraherar anspråk. En SecurityTokenAuthenticator skapas för varje klass som härleds från ServiceModelSecurityTokenRequirement.
