我正在使用pafy模块检索YouTube视频音频的URL。 Pafy本身使用youtube-dl模块连接到youtube。 视频ID位于网址部分：“ / watch？v = videoID”
我存储了这些视频的videoId，但是不时不再有视频可用，因此我需要进行检查。 我尝试实施的检查未能发现一些极端情况，例如该视频对我国的版权禁令。
我已经尝试了2件事。 使用youtube oEmbed API并使用官方youtube API。
import requests
YT_API_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
answers = []
answers2 = []
def isValidVid(vId):
add = f'https://www.youtube.com/oembed?format=json&url=https://www.youtube.com/watch?v={str(vId)}'
answer = requests.get(add)
answers.append(answer)
state = answer.ok
if not state:
print(f'{vId} has become invalid ')
return state
def isValidVid2(vId):
add = f'https://www.googleapis.com/youtube/v3/videos?part=id&id={vId}&key={YT_API_KEY}'
answer = requests.get(add)
answers2.append(answer)
state = answer.ok
if not state:
print(f'{vId} has become invalid ')
return state
vIds=['x26LZrX_vuI', #copyright blocked in my country
'tRqCOIsTx8M', #works fine
]
for vid in vIds:
isValidVid(vid)
isValidVid2(vid)
for a,b in zip(answers,answers2):
print(a.content.split(','),'\n')
print(b.content.split(','),'\n'*2)
Runnig的这段摘要会导致以下输出（对不起，看上去很难看）：

如果我现在使用pafy在使用任何一种验证功能之后现在都检索音频资源的网址，则会在youtube-dl上引发错误，我认为这与您提供无效视频ID时遇到的错误相同：
mrl = pafy.new(vIds[0]).url
OSError: ERROR: HTTP is not supported.
我认为，如果您有一些我在听的技巧，那么与版权禁令（如私人视频）相比，还有更多的陷阱！
感谢您的帮助！
