我有一个无法使用 ASP.NET MVC Core 3.0 解决的问题。登录后，结果成功并成功返回到我想要登录的页面，当我检查cookie或会话时，我可以看到API成功添加了它们。但是当我尝试获取 User.Identity.Name 时，它​​始终为 null，并且 isAuthenticated 始终等于 false。这就像 app.UseAuthentication() 不读取 cookie 或会话。

        services.AddIdentity<IdentityUser, IdentityRole>()
            .AddEntityFrameworkStores<AnisubsDbContext>()
            .AddDefaultTokenProviders();
        services.AddMvc();

        services.AddAuthentication(options =>
        {
            options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
        })
