这是我的Python解决方案，使用谷歌API。 观察:

创建一个.env文件来存储API开发密钥，并将其放入.gitignore文件中 参数“forUserName”应该设置为Youtube频道的名称(用户名)。或者，您可以使用通道id，设置参数为“id”，而不是“forUserName”。 对象“playlistItem”让你访问每个视频。我只展示了它的标题，但还有很多其他属性。

import os
import googleapiclient.discovery
from decouple import config
def main():
    os.environ["OAUTHLIB_INSECURE_TRANSPORT"] = "1"

    api_service_name = "youtube"
    api_version = "v3"
    DEVELOPER_KEY = config('API_KEY')

    youtube = googleapiclient.discovery.build(
        api_service_name, api_version, developerKey = DEVELOPER_KEY)

    request = youtube.channels().list(
        part="contentDetails",
        forUsername="username",
        # id="oiwuereru8987",
    )

    response = request.execute()
    for item in response['items']:
        playlistId = item['contentDetails']['relatedPlaylists']['uploads']
        nextPageToken = ''
        while (nextPageToken != None):
            playlistResponse = youtube.playlistItems().list(
                part='snippet',
                playlistId=playlistId,
                maxResults=25,
                pageToken=nextPageToken
            )
            playlistResponse = playlistResponse.execute()
            print(playlistResponse.keys())
            for idx, playlistItem in enumerate(playlistResponse['items']):
                print(idx, playlistItem['snippet']['title'])
            if 'nextPageToken' in playlistResponse.keys():
                nextPageToken = playlistResponse['nextPageToken']
            else:
                nextPageToken = None

if __name__ == "__main__":
    main()

示例:.env文件

API_KEY=<Key_Here>

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}

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>';

使用gapi JavaScript API可以做到这一点

<script src="https://apis.google.com/js/api.js"></script>

const start = () => {
  gapi.client
    .init({
      apiKey: "your_youtubeApiKey",
      discoveryDocs: ["https://www.googleapis.com/discovery/v1/apis/youtube/v3/rest"],
      scope: "https://www.googleapis.com/auth/youtube.readonly",
    })
    .then(() => {
      console.log("gapi.client initiated");
    })
    .then(() =>
      gapi.client.youtube.channels.list({
        part: "snippet,contentDetails,statistics",
        id: "youtube_channelId",
        // forUsername: 'Bankless',
      })
    )
    .then(
      (res) =>
        // get the youtube related playlist id
        res.result.items[0].contentDetails.relatedPlaylists.uploads
    )
    .then((playlistId) =>
      gapi.client.youtube.playlistItems.list({
        part: "snippet",
        playlistId,
        maxResults: 50,
      })
    )
    .then((res) =>
      // get youtube videos snippets
      res.result.items.map((item) => item.snippet)
    )
    .then((snippets) =>
      snippets.map((snippet) => {
        const { title, description, resourceId } = snippet;
        const { videoId } = resourceId;
        return { title, description, videoId };
      })
    )
    .then((videos) => {
      console.log(videos);
    })
    .catch((err) => console.error(err));
};
gapi.load("client", start);

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);
