检查特定用户是否对discord.py有反应

D先生

我正在寻找一个脚本来检查执行命令（ctx.message.author）的用户是否对带有复选标记的消息做出了反应，它应该看起来像这样：

@client.command()
async def test(ctx):
    message = await ctx.send("Test")
    for emoji in ('✅'):
        await message.add_reaction(emoji) 
        # Here it should detect if the ctx.message.author has reacted

您可以通过用户的ID并使用进行检查wait_for：

import asyncio # for the exception

@client.command()
async def test(ctx):
    message = await ctx.send("Test")
    for emoji in ('✅'):
        await message.add_reaction(emoji) 

        try:

            # the wait_for will only register if the following conditions are met
            def check(rctn, user):
                return user.id == ctx.author.id and str(rctn) == '✅'

            # timeout kwarg is optional
            rctn, user = await client.wait_for("reaction_add", check=check, timeout=30)

            # then execute your code here if the author reacts, like so:
            await ctx.send("I detected the author reacting!")

        # throws this error if user doesn't react in time
        # you won't need this if you don't provide a timeout kwarg in wait_for()
        except asyncio.TimeoutError:
            await ctx.send("Sorry, you didn't react in time!")
