rails amp форму запроса на ошибку и ответа access-control-allow-origin

Question

Я использую рельсовый усилитель и задаю маршрут для усилителя для контактной формы

 <form id='contactusform' method="POST" class="p2" action-xhr = "<%= addquery_path %>" custom-validation-reporting="as-you-go" target="_top">

</div>
<div submit-error>
  <template type="amp-mustache">
    Subscription failed!
  </template>
</div>
    </form>

И мой контроллер сохраняет форму в моей базе данных, но браузер выдает ошибку.

  def addquery
    @contact = Lead.new
    @contact.name = params[:name]
    @contact.email = params[:email]
    @contact.phone = params[:phone]
    @contact.city = params[:city]
    @contact.state = params[:state]
    @contact.country = params[:country]
    @contact.enquiry_type = params[:eventtype]
    @contact.message = params[:message]
    @contact.save
  end

когда я пытаюсь отправить форму AMP, она показывает

Запрос об ошибке формы усилителя должен иметь access-control-allow-origin

в консоли браузера.

, а также

ответ должен иметь access-control-allow-origin

Answer 1

Установить access-control-allow-origin: <your domain> в качестве заголовка ответа в обработчике формы в рельсах.

Пример, если вы работаете на локальном хосте, задайте заголовок ответа формы как access-control-allow-origin: http://localhost:3000
