How do Ii get the value from within my application controller, e.g:

如何从我的应用程序控制器中获取值，例如：

class ApplicationController < Mcc::CoreSupport::FrontendController
  def some_method
    value = xxx
  end
end

2 个解决方案

#1

The class method ActionController::Base.session_options returns a hash of the configuration options for the session.

类方法ActionController :: Base.session_options返回会话配置选项的哈希值。

So in your case you want ActionController::Base.session_options[:domain]

所以在你的情况下你想要ActionController :: Base.session_options [：domain]

#2

In Ruby on Rails 3, you can access the config through Rails.application.config
