只需三步:

订阅:list -> https://www.googleapis.com/youtube/v3/subscriptions?part=snippet&maxResults=50&mine=true&access_token= {oauth_token} 通道:list -> https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id= {channel_id}关键= {YOUR_API_KEY} PlaylistItems: list -> https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId= {playlist_id}关键= {YOUR_API_KEY}

试着像下面这样做。它可能对你有帮助。

https://gdata.youtube.com/feeds/api/videos?author=cnn&v=2&orderby=updated&alt=jsonc&q=news

在这里作者，你可以指定你的频道名称和“q”，因为你可以给你的搜索关键字。

你需要看看YouTube数据API。您将在那里找到关于如何访问API的文档。您还可以找到客户端库。

你也可以自己提出要求。下面是一个从频道检索最新视频的示例URL:

https://www.googleapis.com/youtube/v3/search?key={your_key_here}&channelId={channel_id_here}&part=snippet,id&order=date&maxResults=20

之后，你会收到一个包含视频id和详细信息的JSON，你可以像这样构建你的视频URL:

http://www.youtube.com/watch?v={video_id_here}

最近，我不得不从一个频道检索所有视频，根据YouTube开发者文档: https://developers.google.com/youtube/v3/docs/playlistItems/list

function playlistItemsListByPlaylistId($service, $part, $params) {
    $params = array_filter($params);
    $response = $service->playlistItems->listPlaylistItems(
        $part,
        $params
    );

    print_r($response);
}

playlistItemsListByPlaylistId($service,
    'snippet,contentDetails',
    array('maxResults' => 25, 'playlistId' => 'id of "uploads" playlist'));

$service是Google_Service_YouTube对象。

因此，您必须从频道获取信息以检索“uploads”播放列表，该列表实际上包含该频道上传的所有视频:https://developers.google.com/youtube/v3/docs/channels/list

如果这个API是新的，我强烈建议将代码样例从默认代码片段转换为完整的样例。

因此，从一个频道检索所有视频的基本代码可以是:

class YouTube
{
    const       DEV_KEY = 'YOUR_DEVELOPPER_KEY';
    private     $client;
    private     $youtube;
    private     $lastChannel;

    public function __construct()
    {
        $this->client = new Google_Client();
        $this->client->setDeveloperKey(self::DEV_KEY);
        $this->youtube = new Google_Service_YouTube($this->client);
        $this->lastChannel = false;
    }

    public function getChannelInfoFromName($channel_name)
    {
        if ($this->lastChannel && $this->lastChannel['modelData']['items'][0]['snippet']['title'] == $channel_name)
        {
            return $this->lastChannel;
        }
        $this->lastChannel = $this->youtube->channels->listChannels('snippet, contentDetails, statistics', array(
            'forUsername' => $channel_name,
        ));
        return ($this->lastChannel);
    }

    public function getVideosFromChannelName($channel_name, $max_result = 5)
    {
        $this->getChannelInfoFromName($channel_name);
        $params = [
            'playlistId' => $this->lastChannel['modelData']['items'][0]['contentDetails']['relatedPlaylists']['uploads'],
            'maxResults'=> $max_result,
        ];
        return ($this->youtube->playlistItems->listPlaylistItems('snippet,contentDetails', $params));
    }
}

$yt = new YouTube();
echo '<pre>' . print_r($yt->getVideosFromChannelName('CHANNEL_NAME'), true) . '</pre>';

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)

下面是一个来自谷歌开发者的视频，展示了如何在YouTube API的v3中列出一个频道中的所有视频。

有两个步骤:

查询Channels以获得“uploads”Id。例如https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails 使用这个“uploads”Id查询PlaylistItems以获得视频列表。例如https://www.googleapis.com/youtube/v3/playlistItems?playlistId={"uploads" Id}&key={API key}&part=snippet&maxResults=50
