解决办法
增加
CustomAuthorizeFilter：public class CustomAuthorizeFilter : IDashboardAuthorizationFilter { public bool Authorize([NotNull] DashboardContext context) { return true; } public CustomAuthorizeFilter() { } }
Configure增加配置，代码也可以其他地方，用下面代码替换原先 app.UseHangfireDashboard() 即可。
：
app.UseHangfireDashboard("/hangfire", new DashboardOptions { Authorization = new[] { new CustomAuthorizeFilter() } });
