如何使用discord.py按ID删除特定消息

Question

I am trying to delete a message using it's ID. I am using discord.py.

Logic Flow

User sends command. example: !message hi
Bot deletes "!message hi" using User's message ID
Bot says "hi"

I have figured out how to get it to copy my messages, but I am having difficulty getting it to delete them. I didn't want to say that it deletes the message before it's one otherwise on busy servers it might not work. I wanted to get the command message's ID then delete it using it's ID.

Answer 1

To answer the question: To delete a message by ID, you must either fetch the message object (preferred) or go through client.http (not-preferred)

---

First option: Finding the message.

You can use the Client.get_message function

msg = await client.get_message(channel, message_id)

Alternately, your specific use case seems to just be deleting the message that was sent, so you could just use the message supplied by on_message(msg)
After you have the message, you can do:

await client.delete_message(msg)

Edit for discord.py v1.2+

You should use the Channel.fetch_message function instead.

msg = await channel.fetch_message(message_id)
await msg.delete()

---

Second option: Using client.http

Assuming you know the channel's ID, you can simply call

await client.http.delete_message(channel_id, message_id)

This method while useful for deleting arbitrary messages in arbitrary places shouldn't be used if getting the message is feasably an option.

要删除并不获取信息使用TextChannel.delete_messages ，构建一个雪花使用discord.Object 。

await channel.delete_messages([discord.Object(id=message_id)])
