我不得不放弃基本的 WCF UserName/Pwd 安全性并实现我自己的自定义客户端凭据，以保存默认情况下提供的更多信息。

我通过了 this MSDN article ，但我错过了一些东西，因为它不起作用。

首先，我有一些提供自定义 ClientCredentialsSecurityTokenManager 的自定义 ClientCredentials:

public class CentralAuthCredentials : ClientCredentials
{
    public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager()
    {
        return new CentralAuthTokenManager(this);
    }
}

public class CentralAuthTokenManager : ClientCredentialsSecurityTokenManager
{
    private CentralAuthCredentials credentials;

    public CentralAuthTokenManager(CentralAuthCredentials creds) : base(creds)
    {
        this.credentials = creds;
    }

    public override SecurityTokenProvider CreateSecurityTokenProvider(SecurityTokenRequirement tokenRequirement)
    {
        if (this.IsIssuedSecurityTokenRequirement(tokenRequirement) || tokenRequirement.TokenType == CentralAuthToken.TOKEN_TYPE)
            return new CentralAuthTokenProvider(credentials.UserId, credentials.UserPassword, credentials.ImpersonateId, credentials.LoginType);
        else
            return base.CreateSecurityTokenProvider(tokenRequirement);
    }

    public override SecurityTokenAuthenticator CreateSecurityTokenAuthenticator(SecurityTokenRequirement tokenRequirement, out SecurityTokenResolver outOfBandTokenResolver)
    {
        outOfBandTokenResolver = null;
        if (this.IsIssuedSecurityTokenRequirement(tokenRequirement) || tokenRequirement.TokenType == CentralAuthToken.TOKEN_TYPE)
            return new CentralAuthTokenAuthenticator();
        else
            return base.CreateSecurityTokenAuthenticator(tokenRequirement, out outOfBandTokenResolver);
    }

    public override SecurityTokenSerializer CreateSecurityTokenSerializer(SecurityTokenVersion version)
    {
        return new CentralAuthTokenSerializer();
    }
}

CreateSecurityTokenProvider(SecurityTokenRequirement tokenRequirement)
{
    ...
}

public override SecurityTokenSerializer CreateSecurityTokenSerializer(SecurityTokenVersion version)
{
    return new CentralAuthTokenSerializer();
}

public class CentralAuthorizationManagerClient : ClientBase<ICentralAuthorizationManager>, ICentralAuthorizationManager, IDisposable
{
    public PFPrincipal GenerateToken()
    {
        if (!this.ChannelFactory.Endpoint.Behaviors.Contains(typeof(CentralAuthCredentials)))
            throw new ArgumentException("Must set CentralAuthCredentials before calling this method.");
        return base.Channel.GenerateToken();
    }

    public PFPrincipal GenerateToken(CentralAuthToken token)
    {
        this.ChannelFactory.Endpoint.Behaviors.Remove<ClientCredentials>();
        this.ChannelFactory.Endpoint.Behaviors.Add(new CentralAuthCredentials(token));
        return this.GenerateToken();
    }

最佳答案

我在我正在处理的应用程序中遇到了类似的问题，不幸的是我放弃了，因为我无法使自定义凭据正常工作。我现在使用用户名/密码(客户端凭据)和证书(服务凭据)，并将自定义加密的soap header 添加到服务调用中以传递附加信息，例如用户ID等。

关于c# - 使用自定义 ClientCredentials : What is the clientCredentialType to use? 的 WCF 身份验证，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/563037/
