当用户对消息做出反应时如何赋予角色？

Question

我正在尝试创建一个命令，当用户对消息做出反应时，该命令本质上会赋予他们一个角色。我尝试了一些代码，但是当我运行机器人并对预先发送的消息做出反应时，没有发生错误，也没有任何反应。代码如下：

@client.command()
@commands.guild_only()
async def reactionrole(ctx, emoji, *, role):
    roleEmbed = discord.Embed(title='Reaction Roles', description='React to this message with the proper emoji to give yourself the role.', color=discord.Colour.from_rgb(255, 107, 33))
    roleEmbed.add_field(name='Roles & Emojis:', value=f'{emoji} = {role}', inline=True)
    message = await ctx.send(embed=roleEmbed)
    await message.add_reaction(f'{emoji}')

@client.event
async def on_reaction_add(reaction, user):
    Channel = client.get_channel('my id')
    if reaction.message.channel.id != Channel:
        return
    if reaction.emoji == "{emoji}":
      Role = discord.utils.get(user.server.roles, name="event pings")
      await client.add_roles(user, Role)

您可能正在寻找 on_raw_reaction_add 或 client.wait_for，具体取决于您是希望用户对一段时间前已在频道中发送的消息还是在命令中发送的消息做出反应

@client.command()
async def reaction_role(ctx):
    def check(reaction, user):
        return user == ctx.author and str(reaction) == '✅'

    message = await ctx.send('Please react with ✅ to get the role')
    try:
        # Waiting for the reaction
        await bot.wait_for('reaction_add', check=check, timeout=60.0)
        await ctx.author.add_roles(some_role)
    except asyncio.TimeoutError:
        await message.delete()
        await ctx.send('Time is over')

@client.event
async def on_raw_reaction_add(payload):
    if payload.message_id == my_message_id: 
        guild = client.get_guild(payload.guild_id)
        member = guild.get_member(payload.member_id)
        await member.add_roles(some_role)

• bot.wait_for
• on_raw_reaction_add
