通过Google ADS API获取广告系列费用

Question

我正在尝试通过ID跟踪Google ADS广告系列的费用。 代码示例或教程都无济于事。

我只能通过此示例获取广告系列

use Google\AdsApi\AdWords\AdWordsServices;
use Google\AdsApi\AdWords\AdWordsSessionBuilder;
use Google\AdsApi\AdWords\v201809\cm\CampaignService;
use Google\AdsApi\AdWords\v201809\cm\OrderBy;
use Google\AdsApi\AdWords\v201809\cm\Paging;
use Google\AdsApi\AdWords\v201809\cm\Selector;
use Google\AdsApi\Common\OAuth2TokenBuilder;



$oAuth2Credential = (new OAuth2TokenBuilder())
    ->fromFile( __DIR__ .'/key/ads.ini')
    ->build();

$session = (new AdWordsSessionBuilder())
    ->fromFile( __DIR__ .'/key/ads.ini')
    ->withOAuth2Credential($oAuth2Credential)
    ->build();

$adWordsServices = new AdWordsServices();

$campaignService = $adWordsServices->get($session, CampaignService::class);

// Create selector.
$selector = new Selector();
$selector->setFields(array('Id', 'Name'));
$selector->setOrdering(array(new OrderBy('Name', 'ASCENDING')));

// Create paging controls.
$selector->setPaging(new Paging(0, 100));

// Make the get request.
$page = $campaignService->get($selector);

它工作正常。我无法设置其他字段（费用或预算），但会引发错误。
