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);

获取频道列表:

通过forUserName获取频道列表:

https://www.googleapis.com/youtube/v3/channels?part=snippet,contentDetails,statistics&forUsername=Apple&key=

按频道id获取频道列表:

https://www.googleapis.com/youtube/v3/channels/?part=snippet,contentDetails,statistics&id=UCE_M8A5yxnLfW0KghEeajjw&key=

获取通道部分:

https://www.googleapis.com/youtube/v3/channelSections?part=snippet,contentDetails&channelId=UCE_M8A5yxnLfW0KghEeajjw&key=

获取播放列表:

按频道ID获取播放列表:

https://www.googleapis.com/youtube/v3/playlists?part=snippet,contentDetails&channelId=UCq-Fj5jknLsUf-MWSy4_brA&maxResults=50&key=

使用pageToken通过频道ID获取播放列表:

https://www.googleapis.com/youtube/v3/playlists?part=snippet,contentDetails&channelId=UCq-Fj5jknLsUf-MWSy4_brA&maxResults=50&key=&pageToken=CDIQAA

获取PlaylistItems:

通过PlayListId获取PlaylistItems列表:

https://www.googleapis.com/youtube/v3/playlistItems?part=snippet,contentDetails&maxResults=25&playlistId=PLHFlHpPjgk70Yv3kxQvkDEO5n5tMQia5I&key=

获取视频:

通过视频id获取视频列表:

https://www.googleapis.com/youtube/v3/videos?part=snippet,contentDetails,statistics&id=YxLCwfA1cLw&key=

通过多个视频id获取视频列表:

https://www.googleapis.com/youtube/v3/videos?part=snippet,contentDetails,statistics&id=YxLCwfA1cLw,Qgy6LaO3SB0,7yPJXGO2Dcw&key=

获取评论列表

按视频ID获取评论列表:

https://www.googleapis.com/youtube/v3/commentThreads?part=snippet replies&videoId = el * * * * kQak&key = ********** k

按频道ID获取评论列表:

https://www.googleapis.com/youtube/v3/commentThreads?part=snippet replies&channelId = U * * * * * q键= AI * * * * * * * * k

通过allThreadsRelatedToChannelId获取评论列表:

https://www.googleapis.com/youtube/v3/commentThreads?part=snippet replies&allThreadsRelatedToChannelId =加州大学* * * * * ntcQ&key = AI * * * * * k

这里所有的api都是Get方法。

基于频道id，我们不能直接得到所有的视频，这是这里的重点。

对于集成https://developers.google.com/youtube/v3/quickstart/ios?ver=swift

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);

注意:你可以在 登录https://www.youtube.com/account_advanced。

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。

首先，你需要从用户/频道获取代表上传的播放列表的ID:

https://developers.google.com/youtube/v3/docs/channels/list#try-it

您可以使用forUsername={username}参数指定用户名，或者使用mine=true来获得自己的用户名(您需要先进行身份验证)。Include part=contentDetails查看播放列表。

GET https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=jambrose42&key={YOUR_API_KEY}

结果“relatedPlaylists”将包括“likes”和“uploads”播放列表。抓取“上传”播放列表ID。

还要注意，上传播放列表id是你的channelId，前缀是UU而不是UC。

接下来，获取播放列表中的视频列表:

https://developers.google.com/youtube/v3/docs/playlistItems/list#try-it

只需要输入playlistId!

GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=50&playlistId=UUpRmvjdu3ixew5ahydZ67uA&key={YOUR_API_KEY}

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}
