asp.net-core - .NetCore 5 会话在发布后未启动

问题描述

我正在使用 .NetCore API 和 MVC。一切都在本地服务器上运行。但是在发布站点后不会发生会话。项目运作如下：

  1. 用户带有令牌 ID 到网站。
  2. 我正在解析它，然后将重要变量保存到会话中。
  3. 我从会话中获取值。...

如您所见，如果我在会话中遇到错误，其他步骤将失败。我尝试了太多方法，但都没有奏效。我正在添加 Startup.cs/ConfigureServices 和 Configure 方法。

public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddRazorPages().AddRazorRuntimeCompilation();
        services.AddMvc().AddControllersAsServices();

        services.AddWkhtmltopdf("wkhtmltopdf");
        services.AddHttpContextAccessor();
        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.AddSession(options =>
        {
            options.IdleTimeout = TimeSpan.FromMinutes(600);//You can set Time   
            options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
            options.Cookie.SameSite = SameSiteMode.Strict;
            options.Cookie.HttpOnly = true;
            options.Cookie.IsEssential = true;
        });
        services.AddAuthentication();

        services.AddScoped<Business.Business, Business.Business>();
        services.AddSingleton<SharedViewLocalizer>();
        #region Localization and Language
        services.AddLocalization(options => options.ResourcesPath = "Resources");
        services.Configure<RequestLocalizationOptions>(options =>
        {
            var cultures = new[] {
                new CultureInfo("tr-TR"),
                new CultureInfo("en-US"),
                new CultureInfo("de-DE"),
            };
            options.DefaultRequestCulture = new RequestCulture("en-US");
            options.SupportedCultures = cultures;
            options.SupportedUICultures = cultures;
        });
        #endregion

        services.AddMvc(option =>

            option.EnableEndpointRouting = false;
        })
            .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix,
            opts => { opts.ResourcesPath = "Resources"; })
            .AddDataAnnotationsLocalization();
        services.AddRazorPages();
        services.AddServerSideBlazor();
    }


public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())

解决方案

options.Cookie.SameSite = SameSiteMode.None必须用于允许跨站点 cookie 使用。 https://docs.microsoft.com/en-us/aspnet/core/security/samesite?view=aspnetcore-5.0

中间件的顺序很重要。在 UseRouting 之后和 UseEndpoints 之前调用 UseSession。请参阅中间件排序。

https://docs.microsoft.com/en-us/aspnet/core/fundamentals/app-state?view=aspnetcore-5.0

如果您的生产环境由多台服务器组成，那么简单的方法（但不是推荐的方法）是在负载均衡器中启用粘性会话。

使用多台服务器时，推荐使用分布式缓存。更多信息：https ://dzone.com/articles/aspnet-core-session-storage-strategies

您应该考虑根本不使用会话，这将使您的事情变得更容易。
