StackOverflow！youtube-dl只取URL的第一个字母？
我遇到了一些与youtube-dl有关的问题。最近我有这个工作，但我做了一些改变，现在拒绝工作。这里是我的代码：
import youtube_dl
import os
class InvalidURL(Exception):
pass
class SongExists(Exception):
pass
def download(url):
try:
options = {
'format': 'bestaudio/best',
'quiet': False,
'extractaudio': True, # only keep the audio
'audioformat': "wav", # convert to wav
'outtmpl': '%(id)s.wav', # name the file the ID of the video
'noplaylist': True, # only download single song, not playlist
}
with youtube_dl.YoutubeDL(options) as ydl:
r = ydl.extract_info(url ,download=False)
if os.path.isfile(str(r["id"])):
raise SongExists('This song has already been requested.')
print("Downloading", r["title"])
print(str(url))
ydl.download(url)
print("Downloaded", r["title"])
return r["title"], r["id"]
except youtube_dl.utils.DownloadError:
raise InvalidURL('This URL is invalid.')
if __name__ == "__main__":
download("https://www.youtube.com/watch?v=nvHyII4Dq-A")
据我所见，看来我的脚本正在从我的URL中取出第一个字母。有谁知道为什么？作为“Side-quest”，有没有人知道如何进行搜索而不是URL？
这里是我的输出：
