Asp.Net Core 3.1 Cookies 未附加 Razor 页 C#

Question

Cookies 未使用以下代码附加到页面，我尝试将 IsEssential 添加到选项中，但没有成功。 使用 Asp.Net Core 3.1 Razor 页。 这是我的大部分 startup.cs 和附加的 cookie 代码。

启动.cs

 public void ConfigureServices(IServiceCollection services)
        {
            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });
services.AddRazorPages();
            services.AddMvc(config =>
            {
                var policy = new AuthorizationPolicyBuilder()
                                 .RequireAuthenticatedUser()
                                 .Build();
                config.Filters.Add(new AuthorizeFilter(policy));
            });
services.AddHttpContextAccessor();
            services.TryAddSingleton<IActionContextAccessor, ActionContextAccessor>();
            services.AddSignalR();
            services.AddControllers().AddNewtonsoftJson();
            services.AddControllersWithViews().AddNewtonsoftJson();
            services.AddRazorPages().AddNewtonsoftJson();


}
 public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
            }

            app.UseRequestLocalization();
            app.UseStaticFiles();
            app.UseCookiePolicy();
            app.useAuthentication();
            app.UseRouting();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapRazorPages();
                endpoints.MapControllers();
            });

        }

添加 Cookie

            string key = "Cookie";
            var cookieValue = Request.Cookies[key];
            if(cookieValue == null)
            {
                string value = "true";
                var cookieOptions = new CookieOptions()
                {
                    Path = "/",
                    HttpOnly = false,
                    IsEssential = true,
                    Expires = DateTime.Now.AddDays(1),
                };
                HttpContext.Response.Cookies.Append(key, value, cookieOptions);
            }

建议添加 IsEssential 以覆盖 CookiePolicy，但这并没有解决任何问题。 Devtools 应用程序仅显示.AspNetCore.Identity.Application 和.AspNetCore.Antiforgery cookies。

编辑：通过更改解决

 services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

到

    services.ConfigureApplicationCookie(options =>
    {
        // Cookie settings
        options.Cookie.HttpOnly = true;
        options.ExpireTimeSpan = TimeSpan.FromMinutes(5);

        options.LoginPath = "/Identity/Account/Login";
        options.AccessDeniedPath = "/Identity/Account/AccessDenied";
        options.SlidingExpiration = true;
    });

我认为您的 startup.cs 中缺少一行

app.UseAuthentication();

它将身份验证中间件添加到您的应用程序。 您必须在app.UseAuthorization();之前调用它

这样它就这样显示了：

app.UseRequestLocalization();
        app.UseStaticFiles();
        app.UseCookiePolicy();
        app.UseRouting();
        app.UseAuthentication();
        app.UseAuthorization();
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapRazorPages();
            endpoints.MapControllers();
        });

如果您按照https://learn.microsoft.com/es-es/as.net/core/security/authentication/identity?view=as.netcore-3.1&tabs=visual-studio中的说明进行操作，它应该可以正常工作。
