NET7中简单的登录判断基类

    public class BaseController : Controller
    {
        public override void OnActionExecuting(ActionExecutingContext context)
        {
            base.OnActionExecuting(context);
            int? adminid = HttpContext.Session.GetInt32("adminid");
            if (adminid == null || adminid.Value == 0)
            {
                context.Result = Content("<meta charset=\"utf-8\">您未登录!!!<a href='/admin/login/' target='_parent'>点此登录</a>", "text/html");
            }
        }

    }
