使用youtube-dl来提取仅下载链接的脚本？

Question

我是新来的python，我正在写一个python脚本来使用youtube-dl来提取下载链接，就像控制台给出的链接（youtube-dl -get-url url）一样。 我不想下载媒体，我只需要我的脚本中的下载链接。

Answer 1

>>> from youtube_dl import YoutubeDL # $ pip install youtube-dl 
>>> url = 'https://www.youtube.com/watch?v=pvAsqPbz9Ro' 
>>> ydl = YoutubeDL() 
>>> r = ydl.extract_info(url, download=False) 
[youtube] pvAsqPbz9Ro: Downloading webpage 
[youtube] pvAsqPbz9Ro: Downloading video info webpage 
[youtube] pvAsqPbz9Ro: Extracting video information 
[youtube] pvAsqPbz9Ro: Downloading DASH manifest 
[youtube] pvAsqPbz9Ro: Downloading DASH manifest 
>>> r['url'] 
u'https://r6---sn-n8v7zne7.googlevideo.com/videoplayback?...&ipbits=0' 

如果有几个媒体格式，然后让媒体的网址最后格式：

with youtube_dl.YoutubeDL(dict(forceurl=True)) as ydl: 
    r = ydl.extract_info(url, download=False) 
    media_url = r['formats'][-1]['url']
