ruby - rails限制多个IP访问的方法？

Question

对某一个action的IP的限制方式是，在routes.rb中：

  constraints(:ip => Settings.ip.allow) do
     post '/somecontroller/callback', to: 'somecontroller#callback' , as: 'somecontroller_callback'
  end

在settings.yml中：

  ip:
    allow: '127.0.0.1'

这是可以的.

但是想对多个IP允许访问，在settings.yml中如下：

  ip:
    allow: '/127.0.0.1|127.0.0.2/'

却不行。哪里不对呢？

Answer 1

Because Settings.ip.allow always returns String, but in fact, in the second case, what you need is a RegExp, so it is invalid. You can try changing it like this:

config/routes.rb:

constraints(:ip => %r{#{Settings.ip.allow}}) do
 post '/somecontroller/callback', to: 'somecontroller#callback' , as: 'somecontroller_callback'
end

config/settings.rb

ip:
  allow: '127.0.0.1|127.0.0.2'
