如何防止Rails中的浏览器页面缓存

response.headers['Cache-Control'] = 'no-cache, no-store, max-age=0, must-revalidate'
response.headers['Pragma'] = 'no-cache'
response.headers['Expires'] = 'Fri, 01 Jan 1990 00:00:00 GMT'

config.middleware.insert_before(ActionDispatch::Static, Rack::NoCache)

class Rack::NoCache
  def initialize(app)
    @app = app
  end

  def call(env)
    status, headers, body = @app.call(env)
    headers['Cache-Control'] = 'no-cache, no-store, max-age=0, must-revalidate'
    headers['Pragma'] = 'no-cache'
    headers['Expires'] = 'Fri, 01 Jan 1990 00:00:00 GMT'
    [status, headers, body]
  end
end
