我正在使用 facebook 自动生成的代码尝试连接到营销 API 以获取活动统计信息。这样做，我得到：
Uncaught FacebookAds\Http\Exception\AuthorizationException: (#100) results, actions:like, video_play_actions:video_view, video_avg_time_watched_actions:video_view, unique_actions:link_click 对字段参数无效。
$fields = array(
'results',
'reach',
'actions:like',
'video_play_actions:video_view',
'video_avg_time_watched_actions:video_view',
'unique_actions:link_click',
);
var_dump($fields);
$params = array(
'level' => 'campaign',
'filtering' => array(array('field' => 'campaign.delivery_info','operator' => 'IN','value' => array('active'))),
'breakdowns' => array(),
'time_range' => array('since' => '2017-05-19','until' => '2019-05-19'),
);
echo json_encode((new AdAccount($ad_account_id))->getInsights(
$fields,
$params
)->getResponse()->getContent(), JSON_PRETTY_PRINT);
上面我使用了campaign.delivery_info per this answer。我也试过（根据自动生成的代码）：
'filtering' => array(array('field' => 'delivery_info','operator' => 'IN','value' => array('active')))
