Rails：如何在事件触发之前没有响应
不知道Rails有没有办法做到如下：
- 接收请求
- 将请求放入监听列表，直到有事件触发
- 完成请求但不向客户端返回任何响应（无HTTP响应），触发器将处理后稍后进行响应。
我找到了一些有关delayed_job的信息，但它立即返回响应并将作业置于后台，这似乎不是事件驱动的。
有人可以帮忙吗？

I don't know if Rails has a way to do as following:
- Receive a request
- Put the request into the monitor list until an event triggers
- Finish the request but does not return any response to the client (no HTTP response), the trigger will do the response later after processing.
I found some info about delayed_job, but it returns the response immediately and puts the job to the background which does not seem to be event-driven.
Anyone can help?

我认为你在谈论回调。请阅读此处：API。请注意，您也可以创建自定义事件和回调：博客< /a>
I think you are talking about callbacks. Read here: API. Note that you can create custom events and callbacks too: blog
