Question

这是我的音乐机器人和播放网址代码，我使用 YouTube-Search 和 youtube.dl

@client.command(pass_context=True)
async def play(ctx, search):
    song_there = os.path.isfile("song.mp3")
    yt = YoutubeSearch(search, max_results=1).to_json()
    print('search a "{search}"')
    try:
        yt_id = str(json.loads(yt)['videos'][0]['id'])
        if song_there:
            os.remove("song.mp3")

    [...]
    
    ydl_opts = {'format': 'bestaudio'}
    yt_url = 'https://www.youtube.com/watch?v=' + yt_id
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
      info = ydl.extract_info(video_link, download=False)
      URL = info['formats'][0]['yt_url']
    voice = get(self.bot.voice_clients, guild=ctx.guild)
    voice.play(discord.FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))

试试这个：

import asyncio

import discord
import youtube_dl

from discord.ext import commands

# Suppress noise about console usage from errors
youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': False,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0' # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
    "before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5",
    'options': '-vn'
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)

        if 'entries' in data:

            data = data['entries'][0]

        filename = data['url'] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)

            ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
        embed = discord.Embed(title="Now playing", description=f"[{player.title}]({player.url}) [{ctx.author.mention}]")
        await ctx.send(embed=embed)
