ServiceCredentialsSecurityTokenManager.CreateSecurityTokenAuthenticator Methode

Definitie

Naamruimte:
System.ServiceModel.Security
Assembly:
System.ServiceModel.dll

Hiermee maakt u een beveiligingstoken-verificator op basis van de 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

Parameters

tokenRequirement
SecurityTokenRequirement

De vereiste van het beveiligingstoken.

outOfBandTokenResolver
SecurityTokenResolver

Wanneer deze methode wordt geretourneerd, bevat deze een SecurityTokenResolver. Deze parameter wordt niet-geïnitialiseerd doorgegeven.

Retouren

SecurityTokenAuthenticator

De verificator van het beveiligingstoken.

Uitzonderingen

ArgumentNullException

tokenRequirement is null.

NotSupportedException

Er kan geen beveiligingstoken-verificator worden gemaakt voor de tokenRequirement doorgegeven beveiligingstokens.

Voorbeelden

De volgende code is een voorbeeld van het overschrijven van deze methode.

internal class MyServiceCredentialsSecurityTokenManager :

    }

    public override SecurityTokenAuthenticator CreateSecurityTokenAuthenticator
        (SecurityTokenRequirement tokenRequirement, out SecurityTokenResolver outOfBandTokenResolver)
    {
        // Return your implementation of the SecurityTokenProvider based on the
        // tokenRequirement argument.
        SecurityTokenAuthenticator result;
        if (tokenRequirement.TokenType == SecurityTokenTypes.UserName)
        {

Opmerkingen

Een outOfBand token-resolver kan eventueel worden geretourneerd door de methode, die wordt gebruikt door de WCF-beveiligingsprocessor om tokens op te lossen die zich niet in het SOAP-bericht bevinden bij het verwerken van beveiliging. De SecurityTokenAuthenticator methode die wordt geretourneerd, valideert tokens en extraheert claims. Er SecurityTokenAuthenticator wordt een gemaakt voor elke klasse die is afgeleid van ServiceModelSecurityTokenRequirement.
