ServiceCredentialsSecurityTokenManager.CreateSecurityTokenAuthenticator 方法

定义

命名空间:
System.ServiceModel.Security
程序集:
System.ServiceModel.dll

基于 <a0/> 创建安全令牌验证器。

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

参数

tokenRequirement
SecurityTokenRequirement

安全令牌要求。

outOfBandTokenResolver
SecurityTokenResolver

此方法返回时，包含一个 SecurityTokenResolver. 此参数未初始化传递。

返回

SecurityTokenAuthenticator

安全令牌验证器。

例外

ArgumentNullException

tokenRequirement 是 null。

NotSupportedException

无法为 tokenRequirement 传入的安全令牌验证器创建。

示例

以下代码是如何重写此方法的示例。

internal class MyServiceCredentialsSecurityTokenManager :
    ServiceCredentialsSecurityTokenManager
{
    ServiceCredentials credentials;
    public MyServiceCredentialsSecurityTokenManager(ServiceCredentials credentials)
        : base(credentials)
    {
        this.credentials = credentials;
    }

    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)
        {
            MessageDirection direction = tokenRequirement.GetProperty<MessageDirection>
                (ServiceModelSecurityTokenRequirement.MessageDirectionProperty);
            if (direction == MessageDirection.Input)
            {
                outOfBandTokenResolver = null;
                result = new MySecurityTokenAuthenticator();
            }
            else
            {
                result = base.CreateSecurityTokenAuthenticator(tokenRequirement, out outOfBandTokenResolver);
            }
        }
        else
        {
            result = base.CreateSecurityTokenAuthenticator(tokenRequirement, out outOfBandTokenResolver);
        }

        return result;

注解

outOfBand方法可以选择返回令牌解析程序，该方法由 WCF 安全处理器用来解析处理安全性时不在 SOAP 消息中的令牌。 SecurityTokenAuthenticator此方法返回的令牌和提取声明。 为每个派生自SecurityTokenAuthenticator的类创建一个 ServiceModelSecurityTokenRequirement 。
