PyTube：PrivateVideo 异常不起作用

问题描述

我编写了一个代码，可以在播放列表上打印所有视频的名称。问题是当它尝试打印私有视频的名称时。我从 Github 写了一个异常，所有者写了但它仍然不起作用。它应该跳过这个视频并转到另一个视频，但它没有并且程序崩溃。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)
Traceback (most recent call last):

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

解决方法

异常是在 try/catch 之外产生的。 当 pl.videos 的下一项是 yield 时，它实际上会被引发。

@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

代替调用视频

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

这里我们使用 VideoUnavailable，它是 VideoPrivate 的基类

您将需要以下导入：

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
