无法检索 pagePathLevel1 维度

Can not retrieve pagePathLevel1 dimension

我正在尝试在此处检索 ga:pagePathLevel1 但出现错误

Warning: array_merge(): Argument #2 is not an array in ...\google-api-php-client\src\Google\Service\Analytics.php on line 1925

function getResults(&$analytics, $profileId) {
  // Calls the Core Reporting API and queries for the number of sessions
  // for the last seven days.
  $analytica_report['data_ga_get'] = $analytics->data_ga->get(
      'ga:' . $profileId,
      '7daysAgo',
      'today',
 'ga:sessions,ga:pageviews,ga:uniquePageviews,ga:bounces,ga:timeOnPage,ga:sessionDuration,ga:entrances,ga:exits,ga:searchUniques,ga:transactions',
     'ga:pagePathLevel1,ga:pagePathLevel2'      
      );

任何人都可以建议我如何使其正确吗?

方法中的最后一个参数是可选参数。尝试这样的事情

$optParams = array(
      'dimensions' => 'ga:pagePathLevel1,ga:pagePathLevel2');

  return $service->data_ga->get(
      'ga:' . $profileId,
      '7daysAgo',
      'today',
      'ga:sessions,ga:pageviews,ga:uniquePageviews,ga:bounces,ga:timeOnPage,ga:sessionDuration,ga:entrances,ga:exits,ga:searchUniques,ga:transactions',
      $optParams);
}
