C# .Net core 2.2未将302的状态代码更新为401。OnRedirectToLogin事件未触发

我正在使用identityserver4&我有以下startup.cs文件

当302状态代码存在时，我需要返回状态代码401。但似乎OnRedirectToLogin事件根本没有触发（调试点在事件中没有命中）

这段代码中有什么错误或遗漏了什么。我正在使用.NETCore2.2.1

它已成功编译并正在运行。但响应状态没有改变

ASP.Net核心团队表示，如果使用oidc，将不会触发此事件

但我使用这个oidc进行cookieauthentication。所以我认为它应该（功能请求？）启动

没有标记为公认的答案，因为有人可能对此有意见

试试这个

options.Events.OnRedirectToAccessDenied = context =>
                    {
                        context.Response.StatusCode = 401;
                        return Task.CompletedTask;
                    };

我正在使用identityserver。所以根据我提供的答案。"". 但它仍然没有改变响应状态，调试点也没有到达那里。

options.Events.OnRedirectToAccessDenied = context =>
                    {
                        context.Response.StatusCode = 401;
                        return Task.CompletedTask;
                    };
