Question

我正在尝试在数据库中存储自定义日志记录错误，所以我有

 public enum Events
{
    Error,
    Info,
    Debug
}    

public class Logging
{
    public int LoggingID { get; set; }
    public Events EventName { get; set; }
    public string Message { get; set; }
    public virtual Customer Customer { get; set; }

}

并且我为每个事件制作了一个类似于此示例的消息

 LogHelper.Infos(" Running application ");
        ConfigureAuth(app);

如何将这些事件存储在数据库中？

您可以像这样定义您的Log实体：

public class LogAction
{
        public DateTime PerformedAt { get; set; }
        public string Controller { get; set; }
        public string Action { get; set; }
        public string Description { get; set; }
        public string UserName { get; set; }
        public string Ip { get; set; }
}

然后你可以创建一个这样的自定义属性：

public class LogAttribute : ActionFilterAttribute
    {
        public string Description { get; set; }
        public IUnitOfWork Uow { get; set; }
        public ILogActionService LogActionService { get; set; }

        public IApplicationUserManager ApplicationUserManager { get; set; }
        public LogAttribute(string desciption)
        {
            Description = desciption;
        }


        public override void OnActionExecuted(ActionExecutedContext filterContext)
        {
            string currentUserId = null;
            if (filterContext.HttpContext.User.Identity.IsAuthenticated)
            {
                currentUserId = filterContext.HttpContext.User.Identity.GetUserId();
            }
            var model = new LogAction
            {
                UserName = currentUserId ?? "Anonymouse user",
                Action = filterContext.ActionDescriptor.ActionName,
                Controller = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName,
                Description = Description,
                PerformedAt = DateTime.Now,
                Ip = Helper.Helper.GetUser_IP_Message()
            };
            LogActionService.AddLog(model);
            Uow.SaveAllChanges();
            base.OnActionExecuted(filterContext);
        }
    }

如您所见，在OnActionExecuted方法中，您可以填充实体并将其保存到数据库中，因此您可以这样使用该属性：

[Log("Home Page")]
public ActionResult Index()
{
    return View();
}
