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

我对使用新的ASP.Net OpenID Connect框架在身份验证管道期间添加新声明有疑问，如下面的代码所示。我不确定幕后到底发生了多少“魔法”。我想我的大部分问题都集中在不太了解OWIN认证中间件而不是OpenID Connect

问题1。我是否应该从

OwinContext.Authentication.User

手动设置

HttpContext.Current.User

和

Thread.CurrentPrincipal

问题2。我希望能够像使用

System.IdentityModel.claims.claims那样，将对象类型添加到声明中。新的
System.Security.Claims.Claims
类只接受字符串值吗

第三季度。我是否需要在
System.Security.Claims.CurrentPrincipal
中为我的
ClaimsPrincipal
使用新的
SessionSecurityToken
包装器来序列化为cookie？我正在使用
app.UseCookieAuthentication（新的CookieAuthenticationOptions（））但现在确定这在维护我在
SecurityTokenValidated
事件期间添加的任何附加声明方面究竟起到了什么作用

    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
索赔实体
是否有特定原因

实现目标的最简单方法是通过
ClaimsIdentity claimsId=context.AuthenticationTicket.Identity，检索通过验证传入令牌生成的
ClaimsIdentity
一旦拥有了它，只需添加声明即可。中间件的其余部分将负责在会话cookie中序列化它以及其他所有内容，将结果放入当前的
ClaimsPrincipal
，以及您似乎要手动执行的所有其他操作。
