Asp.Net MVC session过期如何处理跳转

参考地址https://www.cnblogs.com/zemax/p/5607561.html

1.建一个类，如下

using System;
using System.Web.Mvc;
using System.Web.Routing;
 
namespace CheckInManagerSystem.Controllers
{
    public class CheckLogin : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (filterContext.HttpContext.Session != null)
            {
                if (filterContext.HttpContext.Session.IsNewSession)
                {
                    var sessionCookie = filterContext.HttpContext.Request.Headers["Cookie"];
                    if ((sessionCookie != null) && (sessionCookie.IndexOf("ASP.NET_SessionId", StringComparison.OrdinalIgnoreCase) >= 0))
                    {
                        filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { Controller = "Account", Action = "LogOff" }));//这里是跳转到Account下的LogOff,自己定义
                    }
                }
            }
        }
    }
}

2.在每个用到session的Action前增加这个[CheckLogin()]，如

[CheckLogin()]
public ActionResult Details(int userid)
{
　　ViewDataLoad();
    return View(_context.GetUserById(userid));
}

这样就OK啦！不会再因为session过期而报红页面了！
