[TypeFilter(typeof(CustomAsyncActionFilterAttribute))] 或者
[ServiceFilter(typeof(CustomAsyncActionFilterAttribute))]

扩展类CustomActionFilterAttribute

    /// <summary>
    /// ActionFilter
    /// </summary>
    public class CustomActionFilterAttribute : Attribute,IActionFilter

        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="logger"></param>
        public CustomActionFilterAttribute(ILogger<CustomActionFilterAttribute> logger)
        {
            _logger = logger;
        }
        /// <summary>

        /// <param name="context"></param>
        public void OnActionExecuted(ActionExecutedContext context)
        {
            _logger.LogInformation("CustomActionFilterAttribute.OnActionExecuted");
            
        }
        /// <summary>
