python - 我的机器人没有从 URL 播放音乐(搜索)
问题描述
这是我的音乐机器人代码和播放网址,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))
解决方案
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)
class YTDLSource(discord.PCMVolumeTransformer):
def __init__(self, source, *, data, volume=0.5):
super().__init__(source, volume)
self.data = data
self.title = data.get('title')
self.url = data.get('url')
@classmethod
async def from_url(cls, url, *, loop=None, stream=False):
loop = loop or asyncio.get_event_loop()
data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))
if 'entries' in data:
# take first item from a playlist
data = data['entries'][0]
filename = data['url'] if stream else ytdl.prepare_filename(data)
return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)
class Music(commands.Cog):
def __init__(self, client):
self.client = client
@commands.command(description="joins a voice channel")
async def join(self, ctx):
if ctx.author.voice is None or ctx.author.voice.channel is None:
return await ctx.send('You need to be in a voice channel to use this command!')
voice_channel = ctx.author.voice.channel
if ctx.voice_client is None:
vc = await voice_channel.connect()
else:
await ctx.voice_client.move_to(voice_channel)
vc = ctx.voice_client
@commands.command(description="streams music")
async def play(self, ctx, *, url):
async with ctx.typing():
player = await YTDLSource.from_url(url, loop=self.client.loop, stream=True)
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)
@play.before_invoke
async def ensure_voice(self, ctx):
if ctx.voice_client is None:
if ctx.author.voice:
await ctx.author.voice.channel.connect()
else:
await ctx.send("You are not connected to a voice channel.")
raise commands.CommandError("Author not connected to a voice channel.")
elif ctx.voice_client.is_playing():
ctx.voice_client.stop()
