执行代码时出现此错误

致命错误：未捕获的异常'Google_Service_Exception' 消息'调用GET时出错 https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A114460017&start-date=30daysAgo&end-date=today&metrics=ga%3AsessionCount%2Cga%3AsessionDurationBucket%2Cga%3Ausers%2Cga%3ApercentNewSessions%2Cga%3AbounceRate%2Cga%3Apageviews：（400）未知指标：ga：sessionCount，ga：sessionDurationBucket

有谁经历过？我不明白为什么它列出时不能识别这些指标

Answer 1

如果您仔细查看该文档，您会发现会话计数不是指标，而是一个维度。原因是您希望能够按会话计数对指标进行细分（例如，“为具有3个会话的用户显示平均会话持续时间”），并且您需要分类数据。

即使你忽略了目录中的（不是特别有区别的）列标题（ga：sessionCount在“维度”列中），数据类型是字符串这一事实也是一个不错的赠品。指标始终是数字。尺寸总是字符串，即使它们有时看起来像数字。

同样适用于ga：sessionDurationBucket。

请查看此example from the documentation，了解如何通过包含可选参数的数组将维度传递到查询中：

private function queryCoreReportingApi() {
  $optParams = array(
      'dimensions' => 'ga:source,ga:keyword',
      'sort' => '-ga:sessions,ga:source',
      'filters' => 'ga:medium==organic',
      'max-results' => '25');

  return $service->data_ga->get(
      TABLE_ID,
      '2010-01-01',
      '2010-01-15',
      'ga:sessions',
      $optParams);
}

您需要构建一个类似的$ optParams数组：

$optParams = array(
          'dimensions' => 'ga:sessionCount,ga:sessionDurationBucket'
          ');

并将其传递给您的查询：

return $analytics->data_ga->get(
       'ga:' . $profileId,
       '30daysAgo',
       'today',
        $optParams,  
       'ga:users,ga:percentNewSessions,ga:bounceRate,ga:pageviews');
}

并从指标列表中删除维度。

顺便说一下。 Google对维度和指标之间的差异及其在报告中的使用方式有wonderful documentation page。

使用Google指标和维度中列出的指标时出错
