asp.net-core - 无法刷新 Hangfire 仪表板中的统计信息

Question

我的网站在同一台服务器上使用 hangfire 运行。
hangfire 仪表板在本地运行良好。但是，虽然我访问 http://localhost/hangfire/recurring在服务器计算机上，它报告此错误:

Unable to refresh the statistics: the server responded with 500 (Internal Server Error). Try reloading the page manually, or wait for automatic reload that will happen in a minute.

我在 Chrome DevTools 上发现了问题:http://localhost/hangfire/stats 返回 500(内部服务器错误)。
很快我就找到了关于这个的日志:

2021-05-29 15:35:55.6185|7|ERROR|Microsoft.AspNetCore.Antiforgery.DefaultAntiforgery|An exception was thrown while deserializing the token. Microsoft.AspNetCore.Antiforgery.AntiforgeryValidationException: The antiforgery token could not be decrypted.

我在每个 public async Task Invoke(HttpContext context) 中添加了这些代码中间件以防止它阻止挂起，但问题仍然存在:

if (context.Request.Host.Host.ToLower() == "localhost")
            {
                await _next.Invoke(context);
                return;
            }

我该如何解决这个问题？谢谢你。

在startup.cs中添加:

app.UseHangfireDashboard("/hangfire", new DashboardOptions
            {
                Authorization = new[] {new HangfireAuthFilter()},
                IgnoreAntiforgeryToken = true                                 // <--This
            });

现在它起作用了。
