php – 使用Youtube API v3从Youtube频道获取视频列表(没有恼人

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

$OAUTH2_CLIENT_ID = 'xxxxxxxxx';
$OAUTH2_CLIENT_SECRET = 'xxxxxxxxx';

$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);

$channelsResponse = $youtube->channels->listChannels('contentDetails',array(
      'mine' => 'true',

但是,我得到一个恼人的弹出窗口,要求我登录并进行身份验证以获取详细信息.如何摆脱这种身份验证弹出窗口？
我打算写一个cron作业,定期拉出视频列表并将其存储在数据库中,这样我就不想要那个认证弹出窗口了.

注意：当我尝试从播放列表中提取视频时,我不会被要求任何身份验证和api功能顺利

$playlistItemsResponse = $youtube->playlistItems->listPlaylistItems('snippet,status',array(
          'part' => 'snippet,contentDetails','maxResults' => 50,'playlistId' => 'UUGpAMVStIfaQ32K-vhwNIxw'
        ));
