我目前正在使用 python api 开发 Telegram Bot。我在这里使用这个例子https://github.com/python-telegram-bot/python-telegram-bot/blob/master/examples/conversationbot.py。在那个例子中，我希望机器人有一个定时响应。
例如，如果用户在 30 秒内未响应，则发送“你还在吗”消息或其他内容，并在 1 分钟后结束对话。我想实现这样的原因是因为如果没有响应，对话就不会关闭。在我结束脚本之前，它一直处于这种状态。因此用户不能发送 /start 命令重新开始。我能够找到这个https://github.com/python-telegram-bot/python-telegram-bot/blob/master/telegram/ext/conversationhandler.py，它指出我可以启用allow_reentry。我做到了，它解决了用户可以使用命令 /start 一遍又一遍地开始新对话的问题。但我仍然希望在一段时间后结束对话。要结束对话，我需要返回 ConversationHandler.END
我尝试了一个从 9 开始倒计时的 while 循环，每次 time.sleep 为 2。它读取响应 update.message.text 但它只读取命令 /start 这意味着我永远无法在脚本中前进，除非我使用 return GENDER 返回它但我无法找到一种方法来告诉我何时用户选择了性别，然后返回 GENDER。
那么如何实现基于计时器的响应呢？谢谢你
