赠品机器人 discord.py

Question

一切正常 - 嵌入发送但计时器不起作用，并且在赠品结束时编辑消息。这是我的错误：

Ignoring exception in command giveaway:
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 70, in giveaway
    users = await msg.reactions[0].users().flatten()
IndexError: list index out of range

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: IndexError: list index out of range

如果有人可以发送此代码但已编辑，我将不胜感激。我知道这个问题可能不清楚我是 discord.py 的新手。

from asyncio import sleep
from discord.ext import commands
import discord
from discord import Embed, TextChannel

intents = discord.Intents.default()

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



@client.command()
@commands.guild_only()
@commands.has_permissions(administrator=True)
async def giveaway(ctx, duration: int, channel: discord.TextChannel, *, prize: str):
    reaction = discord.Reaction
    embed = Embed(title=prize,
                  description=f"Hosted by - {ctx.author.mention}\nReact with :tada: to enter!\nTime Remaining: **{duration}** seconds",
                  color=ctx.guild.me.top_role.color,)

    msg = await ctx.channel.send(content=":tada: **GIVEAWAY** :tada:", embed=embed)
    await msg.add_reaction("????")

    users = await msg.reactions[0].users().flatten()
    users.pop(users.index(ctx.guild.me))
    

    while duration:
        await sleep(2)
        duration -= 2
        embed.description = f"Hosted by - {ctx.author.mention}\nReact with :tada: to enter!\nTime Remaining: **{duration}** seconds"
        await msg.edit(embed=embed)
    winner = random.choice(users)
    await ctx.send(f"**Congrats to: {winner}!**")
    embed.description = f"Winner: {winner.mention}\nHosted by: {ctx.author.mention}"
    await msg.edit(embed=embed)
client.run('TOKEN')

您在格式化时犯了一些错误。

1. 嵌入是用discord.Embed 定义的，而不仅仅是Embed
2. await sleep 不应使用，请使用 await asyncio.sleep insted。
3. reaction = discord.Reaction 不是真正的调用，甚至没有在您的代码中使用，我删除的 channel: discord.TextChannel 也是如此。

您似乎还以错误的方式请求响应。我遇到了类似的问题，并稍微更改了您的代码。

我们现在使用不同的方法，而不是 users = await msg.reactions[0].users().flatten()：

import asyncio
from discord.ext import commands
import discord
import random

@client.command()
@commands.guild_only()
@commands.has_permissions(administrator=True)
async def giveaway(ctx, duration: int, *, prize: str):
    embed = discord.Embed(title=prize,
                          description=f"Hosted by - {ctx.author.mention}\nReact with :tada: to enter!\nTime Remaining: **{duration}** seconds",
                          color=ctx.guild.me.top_role.color, )

    msg = await ctx.channel.send(content=":tada: **GIVEAWAY** :tada:", embed=embed)
    await msg.add_reaction("?")
    await asyncio.sleep(10)
    new_msg = await ctx.channel.fetch_message(msg.id)

    user_list = [u for u in await new_msg.reactions[0].users().flatten() if u != client.user] # Check the reactions/don't count the bot reaction

    if len(user_list) == 0:
        await ctx.send("No one reacted.") 
    else:
        winner = random.choice(user_list)
        e = discord.Embed()
        e.title = "Giveaway ended!"
        e.description = f"You won:"
        e.timestamp = datetime.datetime.utcnow()
        await ctx.send(f"{winner.mention}", embed=e)

所以这里的新功能是我们实际上是通过 ID 来fetch 消息，这是一个 API 调用，但获取了我们需要的所有信息。

如果您只想编辑已发布的消息，只需使用以下命令：

await new_msg.edit(content=f"{winner.mention}", embed=e)
