ruby-on-rails – 用于不应存在的模板的Rails ActionView :: Mis

我在生产时从根路径上的某些IP地址随机获取此错误. rails应用程序不支持以下格式：formats => [：gif,“image / x-xbitmap”,：jpeg,“image / pjpeg”,“application / x-shockwave-flash”,“application / vnd.ms” -excel“,”application / vnd.ms-powerpoint“,”application / msword“]因此,如果正在为它们发出请求,则可能会出现此错误.我猜测有人或某个机器人试图对网站进行攻击 – 我如何将这些类型的请求重定向或路由回路径路径,以免产生错误？

ActionView::MissingTemplate: Missing template front_page/index,application/index with {:locale=>[:en],:formats=>[:gif,"image/x-xbitmap",:jpeg,"image/pjpeg","application/x-shockwave-flash","application/vnd.ms-excel","application/vnd.ms-powerpoint","application/msword"],:variants=>[],:handlers=>[:erb,:builder,:raw,:ruby,:coffee,:arb,:jbuilder]}.
