我正在使用这个库在WordPress网站上获取来自YouTube的视频和直播源。代码链接如下:https://github.com/google/google-api-php-client
这段代码过去一个月一直工作正常,但是突然间开始出现随机的“连接失败”的错误(10次尝试中有2次失败,其余正常)。
以下是我遇到错误的代码部分:
当请求良好时,就像这样:
以下是我遇到错误的代码部分:
function googleapis_get_live_event_widget(){
//Youtube Videos and Live Events
require_once( get_stylesheet_directory() . '/lib/google-api-php-client/src/Google/autoload.php' );
$GOOGLE_DEVELOPER_KEY = get_field('cce_api_google_developer_key','option');
$client = new Google_Client();
$client->setDeveloperKey($GOOGLE_DEVELOPER_KEY);
$youtube = new Google_Service_YouTube($client);
try {
$islive = get_field('cce_live_event','option');
$opts = array();
$opts['channelId'] = get_field('cce_api_youtube_channel_id','option');
if($islive) {
$opts['eventType'] = 'live';
}
$opts['type'] = 'video';
$opts['maxResults'] = 1;
$opts['order'] = 'date';
$live_videos = $youtube->search->listSearch('id,snippet',$opts);
$data = array();
$data['live_events'] = $live_videos;
echo Timber::compile('partials/live_event_widget.twig',$data);
} catch (Exception $e) {
$error = array();
$error['message'] = $e->getMessage();
echo Timber::compile('partials/error.twig',$error);
return;
}
}
add_shortcode('googleapis_live_widget','googleapis_get_live_event_widget');

,如果尝试失败,则会出现以下结果:

此时,如果我运行页面,新闻聚合将正常显示。
为解决这种不一致性,我应该寻找什么?
