discord.py -如何从提到的用户中清除消息？

import discord
from discord.ext import commands

intents = discord.Intents.default()
intents.message_content = True

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

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

@bot.command()
async def clear(ctx, user: discord.User):
    def is_mentioned(message):
        return user in message.mentions

    await ctx.message.delete()  # 删除触发清除命令的消息

    # 获取当前频道的消息历史记录
    messages = await ctx.channel.history(limit=100).flatten()

    # 从消息历史记录中筛选出提到指定用户的消息，并删除它们
    mentioned_messages = [message for message in messages if is_mentioned(message)]
    await ctx.channel.delete_messages(mentioned_messages)

bot.run('YOUR_BOT_TOKEN')

pip install discord.py
