python - Discord.py 使机器人不与 DM channel 交互

Question

我正在编写一个小消息记录程序，我希望机器人只记录来自特定公会的消息，为此，我检查了 message.guild.id .但是，当在 DM channel 中发送消息时，这会引发问题。我希望机器人完全忽略 Dm channel ，但我没有太多运气
编码:

@commands.Cog.listener()
    async def on_message(self, message):
        if message.guild.id == Guild ID HERE:
            print(f"{message.author} said --- {message.clean_content} --- in #{message.channel.name}")
        elif message.channel.type is discord.ChannelType.private:
            pass

Ignoring exception in on_message
Traceback (most recent call last):
  File "C:\Python38\lib\site-packages\discord\client.py", line 312, in _run_event
    await coro(*args, **kwargs)
  File "d:\Documents\Bots\DS BOT\cog\Listener.py", line 13, in on_message
    if message.guild.id == Guild ID HERE:
AttributeError: 'NoneType' object has no attribute 'id'

Answer 1

你可以做

if not message.guild:
   # message is from a server
else:
   # message is from a dm.

就是这样。无需检查类型。
