Question

我从“示例”区域中的Discord.py GitHub存储库中复制了基准音频播放器。现在，我正在尝试添加功能正常的YouTube搜索，而不是使用Urls。我要添加/更改什么代码？

此外，如果此处的代码格式错误，对不起，我是这个网站的新手：）

我尝试了一些旧的堆栈溢出问题，但似乎没有一个可以解决。：/

import asyncio

# Suppress noise about console usage from errors

        async with ctx.typing():

            ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
        await ctx.send('Now playing: {}'.format(player.title))

    @commands.command()
    async def volume(self, ctx, volume: int):
        """Changes the player's volume"""
        if ctx.voice_client is None:
            return await ctx.send("Not connected to a voice channel.")
        ctx.voice_client.source.volume = volume / 100
        await ctx.send("Changed volume to {}%".format(volume))

    @commands.command()
    async def disconnect(self, ctx):
        """Stops and disconnects the bot from voice"""
        await ctx.voice_client.disconnect()

    @commands.command()

            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()


bot = commands.Bot(command_prefix=commands.when_mentioned_or("d!"),
                   description='Relatively simple music bot example')

@bot.event
async def on_ready():
    print('Logged in as {0} ({0.id})'.format(bot.user))
    print('------')

bot.add_cog(Music(bot))
bot.run('PutTokenHere')

我没有收到带有当前代码的任何错误消息。

将搜索添加到Discord.py音频播放器
