如何在 .net core 3.1 中实现来自多个 http 上下文的会话？

如何解决如何在 .net core 3.1 中实现来自多个 http 上下文的会话？

我正在调用更新会话的控制器方法。在调用 Microsoft Graph API 方法获取登录用户之前，我可以使用 HttpContext.Session.SetString("Percentage","10"); 正确设置会话。但是当我想在像 LoggedInUser = await _graphServiceClient.Me.Request().GetAsync(); 这样的 Microsoft Graph API 调用之后更新会话时，我想使用 HttpContext.Session.SetString("Percentage","40"); 再次更新会话。现在我遇到了这样的异常：

{"IFeatureCollection 已被释放。\r\n对象名称：'Collection'。"}

我也知道 HttpContext 仅适用于单个 http 请求上下文。我只是想知道这个替代方案来实现针对多个 http 请求上下文的会话。

任何帮助都会更有价值。请帮助我为此花了很多时间，但找不到任何东西。

这是我的控制器操作方法：

private async Task<IActionResult> CallAPI_Click()
        {
            
            try
            {        
                //Setting Session Here        
                HttpContext.Session.SetString("Percentage","10");                                                
                //Calling Microsoft Graph API to get Logged in User
                LoggedInUser = await _graphServiceClient.Me.Request().GetAsync();
                //Updating Session Here and getting exception here
                HttpContext.Session.SetString("Percentage","40");
             }
catch (Exception ex)
            {
                //{"IFeatureCollection has been disposed.\r\nObject name: 'Collection'."}
                Console.WriteLine(ex.Message);
            }
}

这是我的 Startup.cs 文件：

public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            string[] initialScopes = Configuration.GetValue<string>("DownstreamApi:Scopes")?.Split(' ');

            services
            // Use OpenId authentication
            .AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
            // Specify this is a web app and needs auth code flow
            .AddMicrosoftIdentityWebApp(Configuration)
            // Add ability to call web API (Graph)
            // and get access tokens
            .EnabletokenAcquisitionToCallDownstreamApi(options =>
            {
                Configuration.Bind("AzureAd",options);
            },initialScopes)
            // Use in-memory token cache
            // See https://github.com/AzureAD/microsoft-identity-web/wiki/token-cache-serialization
            .AddInMemoryTokenCaches()
            .AddMicrosoftGraph(Configuration.GetSection("DownstreamApi"));

            // Require authentication
            services.AddControllersWithViews(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new Authorizefilter(policy));
            })
            // Add the Microsoft Identity UI pages for signin/out
            .AddMicrosoftIdentityUI();
            
            services.AddScoped<AppData>();

            services.AddRazorPages();

            var path = Directory.GetCurrentDirectory();
            services.AddDataProtection().PersistKeysToFileSystem(new DirectoryInfo($"{path}\\DataProtectionKeys\\Keys.xml"));

            services.AddSession(options => {
                options.IdleTimeout = TimeSpan.FromMinutes(30);
                options.Cookie.HttpOnly = true;
                options.Cookie.IsEssential = true;
            });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app,IWebHostEnvironment env,ILoggerFactory loggerFactory)
        {
            var path = Directory.GetCurrentDirectory();
            loggerFactory.AddFile($"{path}\\SentimentLogs\\Sentiment_Log.txt");

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/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.UseSession();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",pattern: "{controller=Home}/{action=Index}/{id?}");
                endpoints.MapRazorPages();
            });
        }
    }
