PyTube：PrivateVideo 异常不起作用

Question

我写了一个代码，可以打印播放列表中所有视频的名称。问题是当它试图打印私有视频的名称时。我写了一个所有者写的 Github 的异常，但它仍然不起作用。它应该跳过这个视频并转到另一个视频，但它没有，程序崩溃了。这是我的代码：

import pytube
from pytube.exceptions import VideoPrivate

pl = pytube.Playlist("https://www.youtube.com/playlist?list=PLB1PGaMZkETOixDfsnKIOkfJS_cToCHSt")


for video in pl.videos:
    try:
        print(video.title)
    except VideoPrivate:
        continue

错误输出：

python playlist.py
One Direction - Steal My Girl
One Direction - Drag Me Down (Official Video)
One Direction - Story of My Life
One Direction - Night Changes
One Direction - Perfect (Official Video)

    raise VideoPrivate(video_id=self.video_id)
pytube.exceptions.VideoPrivate: 8fGmghrkLco is a private video

Answer 1

异常是在 try/catch 之外产生的。当 pl.videos 的下一项是 yield.

时，它实际上被提出了。

@property
def videos(self) -> Iterable[YouTube]:
    """Yields YouTube objects of videos in this playlist

    :Yields: YouTube
    """
    yield from (YouTube(url) for url in self.video_urls)

您可以使用 video_urls

而不是调用视频

for video in pl.video_urls:
    try:
        print(YouTube(video).title)
    except VideoUnavailable:
        continue

这里我们使用 VideoUnavailable 这是 VideoPrivate

的基类

您需要导入以下内容：

import pytube
from pytube.exceptions import VideoUnavailable
from pytube import YouTube

输出：

One Direction - Steal My Girl
One Direction - Drag Me Down (Official Video)
One Direction - Story of My Life
One Direction - Night Changes
One Direction - Perfect (Official Video)
One Direction - You & I
