这是 route 设置

resources :conts do
    collection do
      post 'notify'
    end
  end

这个是 notify 方法

require 'logger'
class ContsController < ApplicationController
  def union_notify
    logger = Logger.new(STDERR)
    notify_params = params.except(*request.path_parameters.keys)
    logger.debug notify_params
  end
end

报错
