Question

经过研究，我发现自己在这里写：我希望当用户对特定消息做出反应✅时，他必须给它一个角色，然后取消另一个角色。但是尝试一下，我无法在这里找到我使用的代码：

spunta = "✅"

#Avvio del Bot
@client.event
async def on_ready():
    channel = client.get_channel(749639084267536464)
    global message
    message = message.id(751836025697075270)
    await message.add_reaction(msg, spunta)

@client.event
async def on_reaction_add(reaction, user):
    if reaction.user == client.user:
        return
    if reaction.message == message and reaction.emoji == spunta:
        role = get(user.guild.roles, id=691004248753832007)
        await client.add_roles(user, role)

错误：

Ignoring exception in on_ready
Traceback (most recent call last):
  File "C:\Users\PC GIUSEPPE\PycharmProjects\LMIIBot Development\venv\lib\site-packages\discord\client.py", line 312, in _run_event
    await coro(*args, **kwargs)
  File "C:/Users/PC GIUSEPPE/PycharmProjects/LMIIBot Development/LMIIBot Development.py", line 253, in on_ready
    message = message.id(751836025697075270)
NameError: name 'message' is not defined

Answer 1

您可以使用on_raw_reaction_add作为payload传递RawReactionActionEvent。

注意：我使用msg id查找消息本身

@client.event
async def on_raw_reaction_add(payload):
    channel = client.get_channel(payload.channel_id)
    message = await channel.fetch_message(payload.message_id)
    guild = client.get_guild(payload.guild_id)
    reaction = discord.utils.get(message.reactions, emoji=payload.emoji.name)

    # only work if it is the client
    if payload.member.id == client.user.id:
        return

    if payload.message_id == 750089806872314038 and reaction.emoji == '✅':
        role = discord.utils.get(guild.roles, name='ROLE NAME HERE')
        await payload.member.add_roles(role)
        await reaction.remove(payload.member)

由于未定义message，因此收到此错误。您可以使用fetch_message仅在特定频道上执行此操作（我不确定该行会是否可行）。因此，在on_ready事件中，您应将message = message.id()更改为message = channel.fetch_message(id)。这应该对您有用。
