session验证-使用filter过滤器

public override void OnActionExecuting(ActionExecutingContext context)
        {
            string test = context.Controller.ToString();
            if (ValuesController._flag == 0)
            {
                context.Result = new RedirectResult("/api/values/Test");
                ValuesController._flag = 1;
            }
        }
