创建委托令牌 - 无法创建SecurityTokenService

Dam*_*ver 8 c# adfs2.0 .net-4.5 visual-studio-2012

我正在尝试构建一个使用ADFS和声明的系统.目前,这只是一个"玩具"实施.

我已经构建了一个非常简单的MVC Web应用程序,使用Visual Studio中的"Identity and Access ..."向导进行设置,以便与ADFS 2.0服务器通信,并将其部署到IIS服务器.一切正常,我可以检查并列出收到的索赔.

下一步是构建基于Web API的REST服务(表示MVC应用程序将依赖的后端服务),因此我希望将凭据传递给该后端服务器,以便它可以进行适当的授权决定.

所以第一步是让我创建委托令牌(然后,我希望能够根据HttpClient类来计算如何处理它以进行其余的调用).我有这个:

//We need to take the bootstrap token and create an appropriate ActAs token
var rst = new RequestSecurityToken
{
    AppliesTo = new EndpointReference("https://other-iis.example.com/Rest"),
    RequestType = RequestTypes.Issue,
    KeyType = KeyTypes.Symmetric,
    ActAs = new SecurityTokenElement(((BootstrapContext)((ClaimsIdentity)User.Identity).BootstrapContext).SecurityToken)
};

var sts = new SecurityTokenService(); //This line isn't valid
var resp = sts.Issue(System.Threading.Thread.CurrentPrincipal as ClaimsPrincipal, rst);

但是,问题在于它SecurityTokenService是抽象的.我找不到从这个类派生的任何类型的任何System.IdentityModel也不System.IdentityModel.Services及上述不包括的ADFS服务器,我显然需要在某些时候提供任何参考.

当然,我也可能完全走错了路线,或者只是遇到了一个小绊脚石而且看不到远处有一个更大的一个,所以任何有关这方面的建议也会受到赞赏.


我已经看过,例如,Identity Delegation Scenario,但是CreateChannelActingAs当我正在与休息服务交谈时,我认为它不会起作用(或者它会吗?),而且似乎也没有适用于.NET 4.5.

我正在从 ADFS 2.0 请求令牌进行缓存并查看 DisplayToken。也许这可以帮助您入门。

这是我能想到的:

    public SecurityToken GetToken(out RequestSecurityTokenResponse rstr)
    {
        Console.WriteLine("Connecting to STS...");

        WSTrustChannelFactory factory = null;

        try
        {
            if (_useCredentials)
            {
                // use a UserName Trust Binding for username authentication
                factory =
                    new WSTrustChannelFactory(
                        new UserNameWSTrustBinding(SecurityMode.TransportWithMessageCredential),
                        "https://<adfs>/adfs/services/trust/13/UsernameMixed");

                factory.TrustVersion = TrustVersion.WSTrust13;

                // Username and Password here...
                factory.Credentials.UserName.UserName = "username";
                factory.Credentials.UserName.Password = "password";
            }
            else
            {
                // Windows authentication over transport security
                factory = new WSTrustChannelFactory(
                    new WindowsWSTrustBinding(SecurityMode.Transport),
                    "https://<adfs>/adfs/services/trust/13/windowstransport") { TrustVersion = TrustVersion.WSTrust13 };
            }

            var rst = new RequestSecurityToken
                          {
                              RequestType = RequestTypes.Issue,
                              AppliesTo = SvcEndpoint,
                              KeyType = KeyTypes.Symmetric,
                              RequestDisplayToken = true
                          };

            Console.WriteLine("Creating channel for STS...");

            IWSTrustChannelContract channel = factory.CreateChannel();

             Console.WriteLine("Requesting token from " + StsEndpoint.Uri);
             SecurityToken token = channel.Issue(rst, out rstr);
             Console.WriteLine("Received token from " + StsEndpoint.Uri);

            return token;
        }
        finally
        {
            if (factory != null)
            {
                try
                {
                    factory.Close();
                }
                catch (CommunicationObjectFaultedException)
                {
                    factory.Abort();
                }
            }
        }
    }

如果您想使用 ADFS 2.0,您可能必须激活 UsernameMixed Endpoint,并且之后不要忘记重新启动服务!
