服务器端Blazor有时会丢失身份验证状态

标签： blazor-server-side

我正在开发服务器端Blazor应用程序，该应用程序支持“常规”内置身份登录以及AzureAD身份验证（已身份验证的用户随后映射到本地用户）。 身份验证和授权本身可以正常工作。 通过内置身份登录，我得到一个身份验证cookie。 通过AzureAD登录，我得到了Azure cookie和Identity cookie：

Authentication cookies

但是有时应用程序似乎挂起，所有cookie都被删除，身份验证状态消失了。我已经注销了。而且我不知道为什么会这样。 然后，DevTools控制台显示：

blazor.server.js:1 [2020-05-14T19:46:43.201Z] Information: Normalizing '_blazor' to 'https://wwwxxx/xxx/_blazor'.
blazor.server.js:1 [2020-05-14T19:56:56.047Z] Warning: Timeout from HTTP request.

blazor.server.js:1 [2020-05-14T19:56:59.565Z] Information: Normalizing '_blazor' to 'https://wwwxxx/xxx/_blazor'.

Startup.cs如下：

public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(
                    Configuration.GetConnectionString("DefaultConnection")));
            services.AddDefaultIdentity<AppUser>(options =>
                {
                    options.SignIn.RequireConfirmedAccount = true;
                    options.User.RequireUniqueEmail = true;
                })
                .AddRoles<IdentityRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();
            services.AddHttpContextAccessor();

            services.AddRazorPages().AddRazorPagesOptions(options =>
            {
               options.Conventions.AuthorizeFolder("/");
            }).AddMvcOptions(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));
            }); ;
            services.AddServerSideBlazor();
            services.AddScoped<AuthenticationStateProvider, RevalidatingIdentityAuthenticationStateProvider<AppUser>>();

            services.AddAuthentication()
                .AddAzureAD(options => Configuration.Bind("AzureAd", options));
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            //Localization
            app.UseRequestLocalization(app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value);

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapBlazorHub();
                endpoints.MapFallbackToPage("/_Host");
            });
        }

有人知道这个问题吗？有什么建议？ 预先谢谢你！

更新：

似乎WebSocket连接断开了...我不知道为什么：
