Discord.py - 在有人第一次做出反应后检查反应

Question

vote_msg = await ctx.send(embed=embed)
    await vote_msg.add_reaction('✅')
    await vote_msg.add_reaction('❎')
    reaction, member = await ctx.bot.wait_for('reaction_add')
    vote_msg = await vote_msg.channel.fetch_message(vote_msg.id) # refetch message
    # default values
    positive = 0
    negative = 0
    for reaction in vote_msg.reactions:
        if reaction.emoji == '✅':
            positive = reaction.count - 1
        elif reaction.emoji == '❎':
            negative = reaction.count - 1
    print(positive)
    print(negative)

目前我有这个来重新获取消息的反应，我怎样才能让它在有人第一次反应后重新获取它，而不是让它等待 5 秒并检查？

我想你正在寻找on_reaction listener

您可以从reaction.message.reactions 访问所有消息反应 如下：

@bot.event
async def on_reaction_add(reaction, user):
    reactions = reaction.message.reactions
    # DO WHAT YOU WANT HERE
