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

Question

我对使用新的 ASP.Net OpenID Connect 框架并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。我不确定幕后发生了多少“魔法”。我认为我的大部分问题都围绕着对 OWIN 身份验证中间件而不是 OpenID Connect 了解太多。

一季度。我应该从OwinContext.Authentication.User<\/code>手动设置HttpContext.Current.User<\/code>和Thread.CurrentPrincipal<\/code>吗？

Q2。我希望能够像以前使用System.IdentityModel.Claims.Claim<\/code>那样向声明添加对象类型。新的System.Security.Claims.Claim<\/code>类只接受字符串值？

Q3。我是否需要在System.Security.Claims.CurrentPrincipal<\/code>为我的ClaimsPrincipal<\/code>使用新的SessionSecurityToken<\/code>包装器来序列化为 cookie - 我正在使用app.UseCookieAuthentication(new CookieAuthenticationOptions());<\/code>但现在确定在维护我在SecurityTokenValidated<\/code>事件期间添加的任何其他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);
                    },
                }
            }
        );
    }

Answer 1

您是否有特定原因要添加新的ClaimsIdentity ？

做你的目标是什么的最简单的方法是检索ClaimsIdentity ，是由验证传入令牌生成的，通过ClaimsIdentity claimsId = context.AuthenticationTicket.Identity; 一旦你拥有它，只需添加声明。 其余的中间件将负责在会话cookie中将其与其他所有内容串行化，将结果放在当前的ClaimsPrincipal ，以及您似乎尝试手动执行的所有其他操作。

执行令牌验证时，您可以直接进行分配：

private Task OnSecurityTokenValidated(SecurityTokenValidatedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> n)
{
    var claimsPrincipal = new ClaimsPrincipal(n.AuthenticationTicket.Identity);
    // Custom code...
    n.OwinContext.Request.User = claimsPrincipal;
    return Task.FromResult(0);
}
