public void OnActionExecuting(System.Web.Mvc.ActionExecutingContext filterContext)
{

if(CheckLogin) //可以定制
{
Staff staff = (Staff)filterContext.HttpContext.Session[SysConstant.STAFF];
if (staff == null)
{
if (filterContext.HttpContext.Request.IsAjaxRequest()) //判断是否ajax请求
{
filterContext.Result = new System.Web.Mvc.JsonResult()
{
Data = new {Code = 301 ,Msg="会话失效，请重新登录"},
ContentEncoding = System.Text.Encoding.UTF8,
JsonRequestBehavior = JsonRequestBehavior.AllowGet,
ContentType = "json"
};
return;
}
else
{
filterContext.Result = new RedirectToRouteResult(
"Default", new System.Web.Routing.RouteValueDictionary(new Dictionary<string, object>() { { "controller", "Home" }, { "action", "Login" } },true)); //重定向
return;
}
}
}
