我一直在使用 message_deleted event ，尽管我似乎无法让它工作。我已经尝试在应用程序中加入此处理程序：
@app.event("message_deleted")
async def message_deleted(ack, body, logger):
logger.info(body)
await ack()
但是，当我删除应用程序生成的消息时，什么也不会发生。事件处理程序没有触发，就好像Slack实际上没有发送任何事件数据以首先通知该消息。
我还转到了我的应用程序设置页面，并注意到有一个标签可以启用事件订阅。我将其打开，并将其指向我的处理程序端点。但是我似乎仍然没有收到任何 message_deleted 事件。在机器人事件或工作区事件下，这似乎不是一个选择。
I've been writing a Slack application using Bolt for Python which can open modals and post messages in channels. What I would like is for a way to detect when the messages posted by my app get deleted (ideally with a simple Python decorator), though I am not sure this is possible. The Slack API does seem to have a message_deleted event, though I can't seem to get it to work. I've tried including this handler in my application:
@app.event("message_deleted")
async def message_deleted(ack, body, logger):
logger.info(body)
await ack()
However, nothing happens when I delete the message that was generated by my app. The event handler doesn't trigger, as if Slack doesn't actually send any event data to notify of the message being deleted in the first place.
I also went to my app's settings page and noticed there is a tab to enable Event Subscriptions. I turned that on and pointed it at my handler endpoint. But I still don't appear to receive any of the message_deleted events. And that doesn't seem to be an option available under either Bot Events or Workspace Events.

message_deleted是Message事件的子类型之一。您的应用程序可以订阅消息（channel/groups/mpim/im）事件以及其侦听器功能可以检查有效载荷中是否有“ Message_Deleted”子类型。The
message_deletedis one of the subtypes formessageevents. Your app can subscribemessage(channels/groups/mpim/im) events plus its listener function can check if there is the "message_deleted" subtype in a payload.
