discord bot (python)如何使用wait_for等待消息或反应

import discord
from discord.ext import commands

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

@bot.command()
async def my_command(ctx):
    def check(message):
        return message.author == ctx.author and message.channel == ctx.channel

    await ctx.send("请发送一条消息来触发等待...")
    try:
        message = await bot.wait_for('message', check=check, timeout=60)  # 等待60秒
        await ctx.send(f"你发送的消息是：{message.content}")
    except asyncio.TimeoutError:
        await ctx.send("等待超时，请重新尝试。")

bot.run('YOUR_BOT_TOKEN')
