python - discord.py - 在音乐机器人上添加队列以解决不和谐和搜索问题

Question

有2个问题。

首先，我尝试为不和谐制作一个音乐机器人，它一直很好，直到我尝试从中播放另一首歌曲，播放另一首歌曲（可能是队列？）我不得不从语音通道中离开机器人并再次编写播放命令（这不是我想要的）并且还尝试从音乐标题播放，而不仅仅是从 url 播放（因为它会进入 youtube 并复制我想要播放的每首歌曲的链接）但它只有在我放undescore 之间的标题（例如“！play name_of_the_song”）我尝试了很多东西，但似乎没有一个有效，所以在这里问是我最后的火腿。

所以我想要的是从播放命令中一首又一首地播放机器人，并且我可以从它的标题中搜索一首歌曲，而无需给我另一首与我正在寻找的歌曲无关的歌曲

我的代码现在看起来像什么：

您可以为公会排队播放音乐。使用内置模块队列，或者仅使用列表。像这样的东西会起作用：

queue = {}
def addToQueue(guild, song):
    if guild.id in queue:
        queue[guild.id] = []
    queue[guild.id].append(song)

async def playSong(ctx, channel):
    async with ctx.typing():
        song = queue[channel.guild.id].pop(0, None)
        if song == None:
            return
        player = await YTDLSource.from_url(song, loop=client.loop, stream=True)
        channel.play(
            player,
            after=lambda e:
            print('Player error: %s' % e) if e else await playSong(ctx, channel)
        )

    await ctx.send('**Now playing:** {}'.format(player.title))

@client.command(name='play', help='This command plays music')
async def play(ctx, url):
    if not ctx.message.author.voice:
        await ctx.send("You are not connected to a voice channel")
        return

    else:
        channel = ctx.message.author.voice.channel
    
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if channel != voice and voice is None:
        await channel.connect()
    elif channel != voice and voice is not None:
        await ctx.send("Already connected to a channel")
        return

    server = ctx.message.guild
    voice_channel = server.voice_client
    addToQueue(ctx.message.guild, url)
    await playSong(ctx, voice_channel)

对于您的搜索问题，您提供的代码似乎并未尝试解决该问题。您将不得不为此使用 Youtube API。
