我想要它搜索视频并播放它，我怎么能改变下面的代码来实现这一点?每次我在ytdl中使用ytsearch函数时，我注意到它只搜索标题的第一个单词并下载它，但是，它稍后会导致错误并且什么也不做。
@commands.command()
async def play(self, ctx, url):
if ctx.author.voice is None:
await ctx.send("You are not in a voice channel!")
voice_channel = ctx.author.voice.channel
if ctx.voice_client is None:
await voice_channel.connect()
else:
await ctx.voice_client.move_to(voice_channel)
ctx.voice_client.stop()
FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
YDL_OPTIONS = {'format':"bestaudio", 'default_search':"ytsearch"}
vc = ctx.voice_client
with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
info = ydl.extract_info(url, download=False)
if 'entries' in info:
url2 = info["entries"][0]["formats"][0]
elif 'formats' in info:
url2 = info["formats"][0]['url']
source = await discord.FFmpegOpusAudio.from_probe(url2, **FFMPEG_OPTIONS)
vc.play(source)
下面是错误信息:
Ignoring exception in command play:

The above exception was the direct cause of the following exception:

谢谢。
解决URL的问题:
url2 = info["entries"][0]["formats"][0]['url']
以及只有一个词被纳入搜索查询的问题:
async def play(self, ctx, *, url):
