這篇文章主要介紹了Asp.net 中mvc 實(shí)現(xiàn)超時(shí)彈窗后跳轉(zhuǎn)功能,非常不錯(cuò)，具有參考借鑒價(jià)值，需要的朋友可以參考下

為了實(shí)現(xiàn)保持登錄狀態(tài),可以用cookie來(lái)解決這一問(wèn)題

假設(shè)過(guò)期時(shí)間為30分鐘,校驗(yàn)發(fā)生在服務(wù)器,借助過(guò)濾器,可以這樣寫(xiě)

 public class PowerFilter : AuthorizeAttribute
  {
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
      var cookie = HttpContext.Current.Request.Cookies["loginInfo"];
      if(null == cookie)
      {
        filterContext.Result = new RedirectResult("/admin/login/index");
      }
      else
      {
        cookie.Expires = DateTime.Now.AddMinutes(30);
        HttpContext.Current.Response.Cookies.Remove("loginInfo");
        HttpContext.Current.Response.Cookies.Add(cookie);
      }
    }
  }

但是頁(yè)面直接跳轉(zhuǎn)了,也沒(méi)有一個(gè)提示,顯得不是很友好,可以這樣

public class PowerFilter : AuthorizeAttribute
  {
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
      var cookie = HttpContext.Current.Request.Cookies["loginInfo"];
      if(null == cookie)
      {
        filterContext.Result = new ContentResult()
        {
          Content = string
          .Format("<script>alert('登錄超時(shí),請(qǐng)重新登錄');location.href='{0}'</script>","/admin/login/index")
        };
      }
      else
      {
        cookie.Expires = DateTime.Now.AddMinutes(30);
        HttpContext.Current.Response.Cookies.Remove("loginInfo");
        HttpContext.Current.Response.Cookies.Add(cookie);
      }
    }
  }
}

但是,假如是ajax請(qǐng)求呢?

public class PowerFilter : AuthorizeAttribute
  {
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
      var cookie = HttpContext.Current.Request.Cookies["loginInfo"];
      if(null == cookie)
      {
        if(!filterContext.HttpContext.Request.IsAjaxRequest())
        {
          filterContext.Result = new ContentResult()
          {
            Content = string
                 .Format("<script>alert('登錄超時(shí),請(qǐng)重新登錄');location.href='{0}'</script>","/admin/login/index")
          };
        }
        else
        {
          filterContext.Result = new JsonResult()
          {
            Data = new { logoff = true,logurl = "/admin/login/index" },
            ContentType = null,
            ContentEncoding = null,
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
          };
        }
      }
      else
      {
        cookie.Expires = DateTime.Now.AddMinutes(30);
        HttpContext.Current.Response.Cookies.Remove("loginInfo");
        HttpContext.Current.Response.Cookies.Add(cookie);
      }
    }
  }
