问题描述

我正在尝试构建一个 Discord Music Bot，我需要使用用户提供的关键字搜索 YouTube.目前我知道如何通过网址播放.

I am trying to build a Discord Music Bot and I need to search the YouTube using keywords given by the user. Currently I know how to play from a url.

       loop = loop or asyncio.get_event_loop()
       data = await loop.run_in_executor( None, lambda: ytdl.extract_info(url, download=not stream))
       if "entries" in data:
            data = data["entries"][0]

        filename = data["url"] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)

推荐答案

Youtube_DL 有一个 extract_info 方法可供您使用.而不是给它一个链接，你只需要像这样传递 ytsearch:args :

Youtube_DL has a extract_info method that you can use. Instead of giving it a link, you just have to pass ytsearch:args like so:

from requests import get
from youtube_dl import YoutubeDL

YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist':'True'}

def search(arg):
    with YoutubeDL(YDL_OPTIONS) as ydl:
        try:
            get(arg) 
        except:
            video = ydl.extract_info(f"ytsearch:{arg}", download=False)['entries'][0]
        else:
            video = ydl.extract_info(arg, download=False)

    return video

此功能的一些重要事项:

A few important things with this function:

• 它适用于单词和网址
• 如果您进行 YouTube 搜索，输出将是一个字典列表.在这种情况下，它将返回第一个结果
• 它将返回一个包含以下信息的字典:

• It works with both words and urls
• If you make a youtube search, the output will be a list a dictionnaries. In this case, it will return the first result
• It will return a dictionnary containing the following informations:

video_infos = search("30 sec video")

#Doesn't contain all the data, some keys are not very important
cleared_data = {
    'channel': video['uploader'],
    'channel_url': video['uploader_url'],
    'title': video['title'],
    'description': video['description'],
    'video_url': video['webpage_url'],
    'duration': video['duration'], #in seconds
    'upload_date': video['upload_data'], #YYYYDDMM
    'thumbnail': video['thumbnail'],
    'audio_source': video['formats'][0]['url'],
    'view_count': video['view_count'],
    'like_count': video['like_count'],
    'dislike_count': video['dislike_count'],
}
