c# - 如何从 ASP.Net OpenID Connect OWIN 组件设置声明？

Question

在身份验证管道期间添加新声明时，我对使用新的 ASP.Net OpenID Connect 框架有疑问，如下面的代码所示。我不确定幕后发生了多少“魔法”。我认为我的大部分问题都围绕着不太了解 OWIN 身份验证中间件而不是 OpenID Connect。

Q1。我应该从 OwinContext.Authentication.User 手动设置 HttpContext.Current.User 和 Thread.CurrentPrincipal 吗？

Q2。我希望能够像以前使用 System.IdentityModel.Claims.Claim 那样将对象类型添加到声明中。新的 System.Security.Claims.Claim 类只接受字符串值？

Q3。我是否需要在 System.Security.Claims.CurrentPrincipal 中为我的 ClaimsPrincipal 使用新的 SessionSecurityToken 包装器以序列化为 cookie - 我正在使用app.UseCookieAuthentication(new CookieAuthenticationOptions()); 但现在确定在维护我在 SecurityTokenValidated 事件期间添加的任何额外声明方面究竟做了什么？

    public void ConfigureAuth(IAppBuilder app)
    {
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
        app.UseCookieAuthentication(new CookieAuthenticationOptions());
        app.UseOpenIdConnectAuthentication(
            new OpenIdConnectAuthenticationOptions
            {
                ClientId = clientId,
                Authority = authority,
                PostLogoutRedirectUri = postLogoutRedirectUri,

                Notifications = new OpenIdConnectAuthenticationNotifications()
                {
                    SecurityTokenValidated = (context) =>
                    {
                        // retriever caller data from the incoming principal
                        var UPN = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.Name).Value;
                        var db = new SOSBIADPEntities();

                        var user = db.DomainUser.FirstOrDefault(b => (b.EntityName == UPN));

                        if (user == null)
                        {
                            // the caller was not a registered user - throw to block the authentication flow
                            throw new SecurityTokenValidationException();
                        }

                        var applicationUserIdentity = new ClaimsIdentity();
                        applicationUserIdentity.AddClaim(new Claim(ClaimTypes.Name, UPN, ""));
                        applicationUserIdentity.AddClaim(new Claim(ClaimTypes.Sid, user.ID.ToString(CultureInfo.InvariantCulture)));


                        var applications =
                            db.ApplicationUser
                            .Where(x => x.ApplicationChild != null && x.DomainUser.ID == user.ID)
                            .Select(x => x.ApplicationChild).OrderBy(x => x.SortOrder);

                        applications.ForEach(x =>
                            applicationUserIdentity.AddClaim(new Claim(ClaimTypes.System, x.ID.ToString(CultureInfo.InvariantCulture))));

                        context.OwinContext.Authentication.User.AddIdentity(applicationUserIdentity);

                        var hasOutlook = context.OwinContext.Authentication.User.HasClaim(ClaimTypes.System, "1");

                        hasOutlook = hasOutlook;

                        HttpContext.Current.User = context.OwinContext.Authentication.User;
                        Thread.CurrentPrincipal = context.OwinContext.Authentication.User;

                        var usr = HttpContext.Current.User;

                        var c =  System.Security.Claims.ClaimsPrincipal.Current.Claims.Count();


                        return Task.FromResult(0);
                    },
                }
            }
        );
    }

您添加新的 ClaimsIdentity 是否有特定原因？

完成您的目标的最简单方法是检索通过验证传入 token 生成的 ClaimsIdentity，通过 ClaimsIdentity claimsId = context.AuthenticationTicket.Identity; 拥有它后，只需向其添加声明即可。中间件的其余部分将负责在 session cookie 中将其连同其他所有内容序列化，将结果放入当前 ClaimsPrincipal，以及您似乎试图手动执行的所有其他操作。< br/>哈特
