yt-dlp 或discord.ext 出错

Question

这是我的代码

from discord.ext import commands
from discord.utils import get
from yt_dlp import YoutubeDL

bot = commands.Bot(command_prefix='!', intents= discord.Intents.all())
YDL_OPTIONS = {'format': 'worstaudio/best', 'noplaylist': 'False', 'simulate': 'True', 'key': 'FFmpegExtractAudio'}
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}

@bot.event
async def on_ready():
  print('connected')

@bot.command()
async def join(ctx):
  channel = ctx.message.author.voice.channel
  voice = get(bot.voice_clients, guild = ctx.guild)

  if voice and voice.is_connected():
    await voice.move_to(channel)
  else:
    voice = await channel.connect()
    await ctx.send(f'Бот присоеденился к каналу : {channel}')
@bot.command()
async def leave(ctx):
  voice = get(bot.voice_clients, guild=ctx.guild)

  if voice and voice.is_connected():
    await voice.disconnect()
    await ctx.send('Бот покинул канал.')
  else:
    await ctx.send('Бот не находится в голосовом канале.')

@bot.command()
async def play(ctx, url):
  with YoutubeDL(YDL_OPTIONS) as ydl:
    if 'https://' in url:
      info = ydl.extract_info(url, download=False)
    else:
      info = ydl.extract_info(f"ytsearch:{url}", download=False)['entries'][0]
  link = info['formats'][0]['url']

  vc.play(discord.FFmpegPCMAudio(executable="ffmpeg\\ffmpeg.exe", source=link, **FFMPEG_OPTIONS))


bot.run('TOKEN')

这是我的日志

我需要机器人从 youtube 视频中提取音频并在语音通道中播放它，机器人已连接到语音通道，我不明白为什么会出现该错误，而且我不明白为什么代码不理解“vc”，但它搜索了视频，我认为已下载，但它不读取“vc”，这是我的问题。

Answer 1

您的机器人需要知道它位于哪个语音通道才能播放音频，因为您的

!play

命令中未定义 vc。

vc = get(bot.voice_clients, guild = ctx.guild)

只需在 !play 命令中添加 !join 命令中的代码，看看它是否有效。
