使用https + Rails 3.0.10时发生重定向问题

Question

寻找任何赞赏的帮助。

我正在使用 Heroku 上托管的 Rails 3.0.10 应用程序，该应用程序最近添加了ssl。我的 Api :: BaseController 看起来像这样。

alias_method :original_inherited, :inherited

def inherited(subclass)
  original_inherited(subclass)

  load File.join("#{Rails.root}", "app", "controllers",
                 "api", "#{extract_filename(subclass)}")

  subclass.action_methods.each do |method|
    regex = Regexp.new("^(.*)_(\\d+)$")
    if match = regex.match(method)
      key = "#{subclass.to_s}##{match[1]}"
      @@versions[match[2].to_i] = true
      @@registered_methods[key] ||= {}
      @@registered_methods[key][match[2].to_i] = true

      subclass.instance_eval do
        define_method(match[1].to_sym) {}
      end
    end
  end
  subclass.reset_action_methods
end

def extract_filename(subclass)
  classname = subclass.to_s.split('::')[1]
  parts = classname.underscore.split('_')
  "#{parts.reject{|c| c == 'controller'}.join('_')}_controller.rb"
end

def reset_action_methods
  @action_methods = nil
  action_methods
end

当我发出任何请求时，它就会在这里出现，并且在某些API中，它会像这样进行重定向调用。
