一、自定义一个Action过滤器
public class CheckSession: ActionFilterAttribute ???{ ???????public override void OnActionExecuting(ActionExecutingContext filterContext) ???????{ ???????????object[] attrs = filterContext.ActionDescriptor.GetCustomAttributes(typeof(NoFilter), true); ???????????if (attrs.Length == 1){} ???????????else { ????????????????if (filterContext.HttpContext.Session != null) ???????????????{ ???????????????????if (filterContext.HttpContext.Session.IsNewSession) ???????????????????{ ???????????????????????var loginUser = filterContext.HttpContext.Session["User"]; ???????????????????????if (loginUser == null) ???????????????????????{ ???????????????????????????if (!filterContext.HttpContext.Request.IsAjaxRequest()) ???????????????????????????{ ???????????????????????????????filterContext.Result = new RedirectResult("/GY_User/LoginIndex"); ???????????????????????????} ???????????????????????????else ???????????????????????????{ ???????????????????????????????filterContext.Result = new JsonResult ???????????????????????????????{ ???????????????????????????????????Data = new ???????????????????????????????????{ ???????????????????????????????????????Success = false, ???????????????????????????????????????Message = string.Empty, ???????????????????????????????????????Redirect = "/GY_User/LoginIndex" ???????????????????????????????????} ???????????????????????????????}; ???????????????????????????} ???????????????????????} ???????????????????} ???????????????} ???????????} ???????????// base.OnActionExecuting(filterContext); ???????} ???} ??//不想使用全局过滤器可使用此标签 ???public class NoFilter:Attribute ???{ ???????public NoFilter() { } ???}二、注册全局过滤器
在FilterConfig中添加
public static void RegisterGlobalFilters(GlobalFilterCollection filters) ???????{ ??????????// filters.Add(new HandleErrorAttribute()); ???????????filters.Add(new CheckSession()); ???????}在Global.asax中添加
protected void Application_Start() ???????{ ???????????AreaRegistration.RegisterAllAreas(); ???????????RouteConfig.RegisterRoutes(RouteTable.Routes); ???????????FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); ???????}三、在不想使用全局过滤器的Action上添加[NoFilter]标签
四、设置Session过期时间
Session["User"] = jsonData.data; Session.Timeout = 3;
MVC过滤器处理Session过期
