ruby-on-rails – 无法创建在Rails中具有带前导点的段的路由(以

在Heroku的Rails 5应用程序中,我正在尝试为此URL创建路由： http://beta.example.com/.well-known/acme-challenge/some-key,因此我可以使用Let’s Encrypt验证我的服务器以获取SSL证书.但是我无法使路线在路线的任何路段中使用前导点或句点,它只返回404 Not Found.

换句话说,.well知道开头的点是搞砸了.我可以在没有点的情况下获得工作路线,或者如果点在其他地方(例如,well.known),但是如果点是段中的第一个字符,则它不起作用.

我从这开始：

get "/.well-known/acme-challenge/:id" => "pages#letsencrypt"

当这不起作用时,我尝试使用(dynamic segment)：

get ':letsencrypt_route/acme-challenge/:id',to: "pages#letsencrypt",letsencrypt_route: /[^/]+/

这将允许段中的任何位置…除了作为第一个字符,这是我需要它的地方.

知道是什么导致了这个吗？当我尝试导航到一个段中具有前导点的URL时,它甚至不会在我的日志中显示任何内容,它只是一个直接的404.

我已经看到一些人在Rails 4和Rails 5上都遇到了这个问题,而且正在使用Thin或Puma,以及开发和生产中都会发生这种情况.我也试过使用一些letsencrypt宝石,但它在同一点停滞不前.

这是我在两种环境中都带有宝石的Gemfile：
