如何使用youtubedl的搜索功能而不是url来让discord bot播放音乐？(Python)

import discord
import youtube_dl

client = discord.Client()

@client.event
async def on_message(message):
    if message.content.startswith('!play'):
        query = message.content[6:]  # 获取搜索查询字符串
        voice_channel = message.author.voice.channel  # 获取用户所在的语音频道

        # 创建一个youtubedl选项字典
        ydl_opts = {
            'format': 'bestaudio/best',
            'postprocessors': [{
                'key': 'FFmpegExtractAudio',
                'preferredcodec': 'mp3',
                'preferredquality': '192',
            }],
            'noplaylist': True,
            'quiet': True,
        }

        # 使用youtubedl进行搜索
        with youtube_dl.YoutubeDL(ydl_opts) as ydl:
            info = ydl.extract_info(f"ytsearch:{query}", download=False)['entries'][0]
            url = info['formats'][0]['url']

        # 加入语音频道并播放音乐
        voice_client = await voice_channel.connect()
        voice_client.play(discord.FFmpegPCMAudio(url))

client.run('YOUR_BOT_TOKEN')
