python-3.x - 如何让我的 discord.py 机器人在语音 channel 中播放 mp3？

Question

我是 Python 的初学者，我最近开始为一些 friend 和我制作一个不和谐的机器人。我的想法是输入 !startq 并让机器人加入 channel ，播放本地存储在同一文件夹中的 mp3 文件bot.py 也在里面。

import discord, chalk
from discord.ext import commands
import time
import asyncio

bot = commands.Bot(command_prefix = "!")

@bot.event
async def on_ready():
    print("Bot is ready!")

@bot.command()
async def q5(ctx):
    await ctx.send("@here QUEUE STARTING IN 5 MINUTES")

@bot.command()
async def q3(ctx):
    await ctx.send("@here QUEUE STARTING IN 3 MINUTES")

@bot.command()
async def q1(ctx):
    await ctx.send("@here QUEUE STARTING IN 1 MINUTES")

@bot.command()
async def ping(ctx):
    ping_ = bot.latency
    ping =  round(ping_ * 1000)
    await ctx.send(f"my ping is {ping}ms")

@bot.command()
async def startq(ctx):
    voicechannel = discord.utils.get(ctx.guild.channels, name='queue')
    vc = await voicechannel.connect()
    vc.play(discord.FFmpegPCMAudio("countdown.mp3"), after=lambda e: print('done', e))
    bot.run('TOKEN')

到目前为止，我的机器人可以正常加入 channel ，但它实际上并没有播放 mp3。我在“Unofficial Discord API Discord”和其他一些编程 Discords 中问过无数人，但我还没有得到答案。

我对我的不和谐机器人做了类似的事情，这里有一些你可以引用的示例代码。如果您正在播放 mp3 文件，请确保安装 ffmpeg，我在设置机器人时按照此处的说明进行操作 https://github.com/adaptlearning/adapt_authoring/wiki/Installing-FFmpeg

@client.command(
    name='vuvuzela',
    description='Plays an awful vuvuzela in the voice channel',
    pass_context=True,
)
async def vuvuzela(context):
    # grab the user who sent the command
    user=context.message.author
    voice_channel=user.voice.voice_channel
    channel=None
    # only play music if user is in a voice channel
    if voice_channel!= None:
        # grab user's voice channel
        channel=voice_channel.name
        await client.say('User is in channel: '+ channel)
        # create StreamPlayer
        vc= await client.join_voice_channel(voice_channel)
        player = vc.create_ffmpeg_player('vuvuzela.mp3', after=lambda: print('done'))
        player.start()
        while not player.is_done():
            await asyncio.sleep(1)
        # disconnect after the player has finished
        player.stop()
        await vc.disconnect()
    else:
        await client.say('User is not in a channel.')
