从https://stackoverflow.com/a/65440501/2585501:

如果a)该频道有超过50个视频，或者b)希望将youtube视频id格式化为平面txt列表，则此方法特别有用:

Obtain a Youtube API v3 key (see https://stackoverflow.com/a/65440324/2585501) Obtain the Youtube Channel ID of the channel (see https://stackoverflow.com/a/16326307/2585501) Obtain the Uploads Playlist ID of the channel: https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails (based on https://www.youtube.com/watch?v=RjUlmco7v2M) Install youtube-dl (e.g. pip3 install --upgrade youtube-dl or sudo apt-get install youtube-dl) Download the Uploads Playlist using youtube-dl: youtube-dl -j --flat-playlist "https://<yourYoutubePlaylist>" | jq -r '.id' | sed 's_^_https://youtu.be/_' > videoList.txt (see https://superuser.com/questions/1341684/youtube-dl-how-download-only-the-playlist-not-the-files-therein)

使用已弃用的API版本2，用于上传的URL(通道UCqAEtEr0A0Eo2IVcuWBfB9g)是:

https://gdata.youtube.com/feeds/users/UCqAEtEr0A0Eo2IVcuWBfB9g/uploads

有一个API版本3。

下面是返回频道下所有视频id的代码

<?php 
    $baseUrl = 'https://www.googleapis.com/youtube/v3/';
    // https://developers.google.com/youtube/v3/getting-started
    $apiKey = 'API_KEY';
    // If you don't know the channel ID see below
    $channelId = 'CHANNEL_ID';

    $params = [
        'id'=> $channelId,
        'part'=> 'contentDetails',
        'key'=> $apiKey
    ];
    $url = $baseUrl . 'channels?' . http_build_query($params);
    $json = json_decode(file_get_contents($url), true);

    $playlist = $json['items'][0]['contentDetails']['relatedPlaylists']['uploads'];

    $params = [
        'part'=> 'snippet',
        'playlistId' => $playlist,
        'maxResults'=> '50',
        'key'=> $apiKey
    ];
    $url = $baseUrl . 'playlistItems?' . http_build_query($params);
    $json = json_decode(file_get_contents($url), true);

    $videos = [];
    foreach($json['items'] as $video)
        $videos[] = $video['snippet']['resourceId']['videoId'];

    while(isset($json['nextPageToken'])){
        $nextUrl = $url . '&pageToken=' . $json['nextPageToken'];
        $json = json_decode(file_get_contents($nextUrl), true);
        foreach($json['items'] as $video)
            $videos[] = $video['snippet']['resourceId']['videoId'];
    }
    print_r($videos);

由于每个回答这个问题的人都有500个视频限制的问题，这里有一个使用Python 3中的youtube_dl的替代解决方案。此外，不需要API密钥。

安装youtube_dl: sudo pip3 Install youtube_dl 找出目标频道的频道id。ID将以UC开头。将Channel的C替换为Upload的U(即UU…)，这是上传播放列表。 使用youtube-dl的播放列表下载功能。理想情况下，你不希望下载播放列表中的每个视频，这是默认的，而只是元数据。

示例(警告—需要数十分钟):

import youtube_dl, pickle

             # UCVTyTA7-g9nopHeHbeuvpRA is the channel id (1517+ videos)
PLAYLIST_ID = 'UUVTyTA7-g9nopHeHbeuvpRA'  # Late Night with Seth Meyers

with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:

    playd = ydl.extract_info(PLAYLIST_ID, download=False)

    with open('playlist.pickle', 'wb') as f:
        pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)

    vids = [vid for vid in playd['entries'] if 'A Closer Look' in vid['title']]
    print(sum('Trump' in vid['title'] for vid in vids), '/', len(vids))

在最初的问题被问到之后很久才发布，但我做了一个python包，使用一个非常简单的API来做到这一点。它把所有的视频上传到一个频道，但我不确定这一部分(包括在最初的问题中):

上传到一个频道的视频可以来自多个用户，因此我不认为提供用户参数会有帮助…

也许YouTube在这个问题发布后的8年里发生了变化，但如果没有，我制作的软件包可能不包括这个案例。

使用API:

pip3 install -U yt-videos-list # macOS
pip  install -U yt-videos-list # Windows

# if that doesn't work, try
python3 -m pip install -U yt-videos-list # macOS
python  -m pip install -U yt-videos-list # Windows

然后打开一个python解释器

python3   # macOS
python    # Windows

然后运行程序:

from yt_videos_list import ListCreator
lc = ListCreator()

help(lc) # display API information - shows available parameters and functions

my_url = 'https://www.youtube.com/user/1veritasium'

lc.create_list_for(url=my_url)
