Question

嘿，我正在用Python开发Discord Bot。这是文档：https://discordpy.readthedocs.io/en/latest/index.html

如果该程序对消息做出反应，则该程序应赋予用户角色

我试图在函数本身中定义ctx

@client.event
async def on_raw_reaction_add(payload):
    member = discord.utils.get(client.get_all_members())
    role = discord.utils.find(lambda r: r.name == "check-in", ctx.guild.roles)
    check_in = ["612637944544624690"]
    if str(payload.channel_id) in check_in:
        await client.add_roles(member, role, reason="check-in")

这是在函数本身中没有ctx的错误：

Ignoring exception in on_raw_reaction_add
Traceback (most recent call last):
  File "C:\Users\kaitr\Anaconda3\envs\tutorial\lib\site-packages\discord\client.py", line 270, in _run_event
    await coro(*args, **kwargs)
  File "C:/Users/kaitr/PycharmProjects/Discord Tutorial/bot.py", line 39, in on_raw_reaction_add
    role = discord.utils.find(lambda r: r.name == "check-in", ctx.guild.roles)
NameError: name 'ctx' is not defined

函数本身就是ctx的错误：

Ignoring exception in on_raw_reaction_add
Traceback (most recent call last):
  File "C:\Users\kaitr\Anaconda3\envs\tutorial\lib\site-packages\discord\client.py", line 270, in _run_event
    await coro(*args, **kwargs)
TypeError: on_raw_reaction_add() missing 1 required positional argument: 'ctx'

您无权访问invocation context，因为这不是命令。您只能使用有效载荷的属性RawReactionActionEvent对象。这包括一个guild_id属性，可用于获取公会：

@client.event
async def on_raw_reaction_add(payload):
    if payload.guild_id is None:
        return  # Reaction is on a private message
    guild = client.get_guild(payload.guild_id)
    role = discord.utils.get(guild.roles, name="check-in")
    member = guild.get_member(payload.user_id)
    if str(payload.channel_id) in check_in:
        await member.add_roles(role, reason="check-in")
