如何使用Google云端硬盘获取文件修改日期

Question

我使用以下代码查询文件列表：

    $service = new \Google_Service_Drive($google->getClient());
    $files = $service->files->listFiles();

然后返回以下数据（这是print_r转储）。 应该保留日期的所有字段都是空的（它们实际上是空的）。对于所有文件。 设置的字段（文件名，ID等）是正确的。 为什么缺少日期？

我的composer.json有以下一行：

    "google/apiclient": "^2.2",

试试这个：

<?php

$service = new \Google_Service_Drive($google->getClient());
$files = $service->files->listFiles();

foreach($files->getFiles() as $file){
    $createdTime = $file->getCreatedTime();
    $modifyByMeTime = $file->getModifiedByMeTime();
    $modifiedTime = $file->getModifiedTime();
    $sharedWithMeTime = $file->getSharedWithMeTime();
    $trashedTime = $file->getTrashedTime();
    $viewedByMeTime = $file->getViewedByMeTime();
}

?>

所有方法都可在此处找到：Class Google_Service_Drive_DriveFile

尝试添加：

...
    $optParams = array(
      'pageSize' => 10,
      'fields' => 'nextPageToken, files(id, name, createdTime)'
    ); 

    $files = $service->files->listFiles($optParams);
...
