Question

我尝试将HttpContext.Session保存到数据库而不是memmory服务器

问题是没有任何内容保存在表中，会话总是变为空。

这是我的启动代码：

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        services.AddDistributedSqlServerCache(options =>
        {
            options.ConnectionString = @"Data Source=localhost;Initial Catalog=mydb;Integrated Security=True;";
            options.SchemaName = "dbo";
            options.TableName = "SQLSessions";
        });

        services.AddSession(options => {
            options.CookieName = "Test.Session";
            options.IdleTimeout = TimeSpan.FromMinutes(60);
        });

    }


   public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IDistributedCache cache)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseSession();

        app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
        });
        app.UseHttpMethodOverride();
        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}"
                );
            routes.MapRoute(
                name: "AdvertisementImages",
                template: "{controller=Home}/{action=Images}/{type}/{name}", // URL with parameters
                defaults: new {type = 0, name = ""} // Parameter defaults
            );
        });

    }

和我保存会话的控制器代码：

HttpContext.Session.SetObjectAsJson("TryToLogin", newLogin);

和我的会话扩展：

   public static class SessionExtensions
    {
        public static void SetObjectAsJson(this ISession session, string key, object value)
        {
            session.SetString(key, JsonConvert.SerializeObject(value));
        }

        public static T GetObjectFromJson<T>(this ISession session, string key)
        {
            var value = session.GetString(key);

            return value == null ? default(T) : JsonConvert.DeserializeObject<T>(value);
        }
    }

这是我的会话表架构：
