基于用户反应discord.py发送消息

import discord

# 创建一个Discord客户端
client = discord.Client()

@client.event
async def on_ready():
    print('Bot已登录为 {0.user}'.format(client))

@client.event
async def on_message(message):
    if message.author == client.user:
        return

    if message.content.startswith('!hello'):
        await message.channel.send('你好！')

@client.event
async def on_reaction_add(reaction, user):
    if user == client.user:
        return

    if str(reaction.emoji) == '?':
        channel = reaction.message.channel
        await channel.send('谢谢你的反应！')

# 替换为你的Discord机器人令牌
client.run('YOUR_BOT_TOKEN')
