UseStatusCodePagesWithReExecute() 不适用于 .NET Core 3.1

I use UseStatusCodePagesWithReExecute如果应用程序出现问题，将用户重定向到错误页面。

如果我的应用程序中发生错误（例如代码 500），我不会被重定向到“/Home/Error”。 如果我手动调用它“/Home/Error”就可以了！

这是我的代码，错误在哪里？

        public IActionResult Error(string code)
        {
            return View(new ErrorModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier, ErrorStatusCode = code });
        }



public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseSiteOfflineMiddleware(); 

            app.UseStatusCodePagesWithReExecute("/Home/Error", "?code={0}");

            app.UseStaticFiles();
            app.UseRouting();

            app.UseAuthentication(); 
            app.UseAuthorization();
            app.UseSession(); // Aggiungi Supporto Sessioni

            // Dependency Injection Option per leggere Localizzazione File Resources delle lingue
            var localizationOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value;
            app.UseRequestLocalization(localizationOptions);

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "products",
                    pattern: "{codLanguage}/shop/{id}/{nameProduct}",
                    new { controller = "Catalog", action = "Detail" });

                endpoints.MapControllerRoute(
                    name: "catalog",
                    pattern: "/shop",
                    new { controller = "Catalog", action = "Index" });

                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });


            app.Run(async (context) =>
            {
                await Task.CompletedTask;
            });

        }

In the issue https://github.com/aspnet/Mvc/issues/6717正如Tratcher提到的，UseStatusCodePagesWithReExecute适用于没有主体的状态代码响应（例如空404）。而对于像500这样的代码，您可以使用UseExceptionHandler。

如果你想在状态码为500时重定向到“/Home/Error”，你可以这样做：

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
           app.UseExceptionHandler("/Home/Error");
            app.UseStatusCodePagesWithReExecute("/Home/Error", "?code={0}");
