自定义授权过滤器中的访问会话

Question

如何在自定义授权过滤器中使用Session["userName"]？

void IAuthorizationFilter.OnAuthorization(AuthorizationContext filterContext)
{            
    string userName = Session["userName"]; // Shows error "The name 'Session' does not exist in the current context              

    base.OnAuthorization(filterContext);
}

Session字典可以通过以下方式获得：

void IAuthorizationFilter.OnAuthorization(AuthorizationContext filterContext)
{            
    string userName = filterContext.HttpContext.Session["userName"];               

    base.OnAuthorization(filterContext);
}
