Discord.py 票务系统

Question

我已经开始使用 discord.py 制作 Ticket bot，但我的代码中有一个错误，我不知道如何解决它。嵌入并对消息工作做出反应，但是当我尝试做出反应时，一切都崩溃了。这是我的错误：

Ignoring exception in command ticket:
Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "c:\Users\HP\Desktop\222\dscbot-dscbot.py", line 150, in ticket
    if reaction == '????':
NameError: name 'reaction' is not defined

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\bot.py", line 902, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\core.py", line 864, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\HP\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NameError: name 'reaction' is not defined

我希望有人知道如何解决这个问题，这是我当前的代码：

import discord
from discord.ext import commands
from discord.utils import get
from discord import Embed, Color
import DiscordUtils
import os
from discord.ext.commands import has_permissions, MissingPermissions
import json




intents = discord.Intents.default()

intents.members = True
client = commands.Bot(command_prefix = "-", intents = intents)
client.remove_command("help")




@client.command(pass_context=True)
async def ticket(ctx):
    guild = ctx.guild
    embed = discord.Embed(
        title = 'Ticket system',
        description = 'React ???? to make a ticket.',
        color = 0
    )

    embed.set_footer(text="ticket system")

    msg = await ctx.send(embed=embed)
    await msg.add_reaction("????")
    reaction = await msg.fetch_message(msg.id)


    await client.wait_for("reaction_add")



    await client.wait_for("reaction_add")

    if reaction == '????':
        await guild.create_text_channel(name=f'ticket - {reaction.author.name}')

ps：我是 discord.py 的新手

Answer 1

reaction = await msg.fetch_message(msg.id) 只是给你msg。你需要从await client.wait_for("reaction_add")得到反应

看看wait_for。您实施检查（反应在哪里）以查看反应是否是邮箱。

如果反应是邮箱，您需要创建一个创建频道的新函数，然后将其传递给client.wait_for。

def check(reaction, user):
    return str(reaction) == '?' and ctx.author == user

await client.wait_for("reaction_add", check=check)
await guild.create_text_channel(name=f'ticket - {ctx.author}')

Answer 2

您没有定义reaction，这就是引发此错误的原因。 查看this post，了解如何从消息中获取反应。
