为什么在我的命令后调用我的on_消息？

Question

我的代码起作用了。只有一个问题，那就是在调用任何命令后，我的on_message被调用（这会导致一些副作用）

async def delete_on_swear(message):
    if not message:
        return
    db = sqlite3.connect('main.sqlite')
    cursor = db.cursor()
    try:
        guild_id = message.guild.id
    except AttributeError:
        return
    cursor.execute(f'SELECT word FROM badwords WHERE guild_id={guild_id}')
    swears = [swear[0] for swear in cursor.fetchall()]
    if not swears:
        return
    if bot.user == message.author:
        return
    for swearword in swears:
        if not message.channel.is_nsfw() and is_substring(message.content.lower(), swearword):
            await message.delete()
            await message.author.create_dm()
            await message.author.dm_channel.send(
                f'Hi {message.author}, you sent a message containing the following word: {swearword}'
            )
            return```

on_message在机器人可以查看的任何通道中发送任何消息后运行。在您的on_message的顶部，放置以下代码以防止机器人对自己的消息执行操作：

if message.author == bot.user:
    return
