Question

我正在开发一个项目，要求使用youtubedata api 3.0列出来自频道的所有视频但不是来自gdata（feed），Api只返回来自频道的50个视频，并且没有参考可以获得更多关于开发者的视频。谷歌。救命。这是我的代码

<?php

require_once 'contrib/Google_YoutubeService.php';*/
require_once '../upload/google-api-php-client/src/Google_Client.php';
    require_once '../upload/google-api-php-client/src/contrib/Google_YouTubeService.php';
session_start();

/* You can acquire an OAuth 2 ID/secret pair from the API Access tab on the Google APIs Console
  <http://code.google.com/apis/console#access>

  <https://developers.google.com/accounts/docs/OAuth2>
Please ensure that you have enabled the YouTube Data API for your project. */
$OAUTH2_CLIENT_ID = 'sadsadsadasdsad';
$OAUTH2_CLIENT_SECRET = 'sadsadsadasdasdasdasd';

$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
  FILTER_SANITIZE_URL);
$client->setRedirectUri($redirect);

$youtube = new Google_YoutubeService($client);

if (isset($_GET['code'])) {
  if (strval($_SESSION['state']) !== strval($_GET['state'])) {
    die('The session state did not match.');
  }

  $client->authenticate();
  $_SESSION['token'] = $client->getAccessToken();
  header('Location: ' . $redirect);
}

if (isset($_SESSION['token'])) {
  $client->setAccessToken($_SESSION['token']);
}

if ($client->getAccessToken()) {
  try {
    $channelsResponse = $youtube->channels->listChannels('contentDetails', array(
      'mine' => 'true',
    ));

    $htmlBody = '';
    foreach ($channelsResponse['items'] as $channel) {
      $uploadsListId = $channel['contentDetails']['relatedPlaylists']['uploads'];
$pageToken=1;
  while($pageToken<=25){
      $playlistItemsResponse = $youtube->playlistItems->listPlaylistItems('snippet', array(
        'playlistId' => $uploadsListId,
        'maxResults' => 50,

         ));


      $htmlBody .= "<h3>Videos in list $uploadsListId</h3><ul>";
      foreach ($playlistItemsResponse['items'] as $playlistItem) {
        $htmlBody .= sprintf('<li>%s (%s)</li>', $playlistItem['snippet']['title'],
          $playlistItem['snippet']['resourceId']['videoId']);
      }
      $htmlBody .= '</ul>';
    }
  }
  } catch (Google_ServiceException $e) {
    $htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
      htmlspecialchars($e->getMessage()));
  } catch (Google_Exception $e) {
    $htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
      htmlspecialchars($e->getMessage()));
  }

  $_SESSION['token'] = $client->getAccessToken();
} else {
  $state = mt_rand();
  $client->setState($state);
  $_SESSION['state'] = $state;

  $authUrl = $client->createAuthUrl();
  $htmlBody = <<<END
  <h3>Authorization Required</h3>
  <p>You need to <a href="$authUrl">authorize access</a> before proceeding.<p>

Answer 1

Yepp现在已经很晚了，但既然你没有接受答案，请允许我在这里给你解决方案。

说你打了一个网址BaseURL

因此，当您点击api获取前50个视频时，它会为您提供nextPageToken

要获得接下来的50个视频，您只需将此令牌附加到BaseURL，如下所示：

BaseURL + "&pageToken=" +nextPageToken

同样，如果你已经做了一些分页，你也可能会得到一个prevPageToken，现在你只需要像上面解释的那样附加这个标记就可以到达上一页。

Answer 2

YouTube API支持分页。您需要将nextPageToken作为pageToken放在下一个请求中，以获得下一页（在您的情况下为50）结果。

我的这2个答案应该对你有帮助：

page tokens use youtube api v3

Retrieve all videos from youtube playlist using youtube v3 API

youtube data api 3 php，如何从频道获取50多个视频？
