Discord.py让机器人复制每条消息，包括文件

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.messages = True
intents.guilds = True

bot = commands.Bot(command_prefix='!', intents=intents)

@bot.event
async def on_ready():
    print(f'Logged in as {bot.user}')

@bot.event
async def on_message(message):
    if message.author.bot:
        return

    # 复制文本消息
    await message.channel.send(f'Copied message: {message.content}')

    # 复制文件
    if message.attachments:
        for attachment in message.attachments:
            file = await attachment.to_file()
            await message.channel.send(file=file)

    await bot.process_commands(message)

bot.run('YOUR_BOT_TOKEN')
