使用google-drive-api创建子文件夹，并使用PHP返回id

Question

我可以用下面的代码来创建子文件夹，但是我不能返回id。

我想获取文件夹的id和/或链接，以便将它们添加到我的数据库中。

目前，下面的代码创建了文件夹，但只返回"//“作为id！

谢谢你的帮忙

<?php

if ($client->getAccessToken()) {

$file = new Google_DriveFile();

//Setup the Folder to Create
$file->setTitle('Project  Folder');
$file->setDescription('A Project Folder');
$file->setMimeType('application/vnd.google-apps.folder');

//Set the ProjectsFolder Parent
$parent = new Google_ParentReference();
$parent->setId('0B9mYBlahBlahBlah');
$file->setParents(array($parent));

//create the ProjectFolder in the Parent
$createdFile = $service->files->insert($file, array(
    'mimeType' => 'application/vnd.google-apps.folder',
));

// print_r($createdFile);
print "folder created sucessfully";
echo "folder id is" . $createdFile->id;
}
?>

Answer 1

也许这不是一种花哨的方式，但这是我获取文件夹ID的方法：

$service = new Google_DriveService($client);

$files = $service->files->listFiles();
foreach ($files['items'] as $item) {
    if ($item['title'] == 'your_folder_name') {
        $folderId = $item['id'];
    break;
    }
}

Answer 2

$files = $service->files->listFiles(array('maxResults' => 1));
var_dump($files['items'][0]['id']); 

Answer 3

我认为方法已经更新了，所以我使用了新的方法。Here is the library

if ($client->getAccessToken()) {
      $file = new Google_Service_Drive_DriveFile();
      $file->title = "New File By Bikash 111";
      // To create new folder
      $file->setMimeType('application/vnd.google-apps.folder');


      // To set parent folder
      $parent = new Google_Service_Drive_ParentReference();
      $parent->setId('0B5kdKIFfgdfggyTHpEQlpmcExXRW8');
      $file->setParents(array($parent));

      $chunkSizeBytes = 1 * 1024 * 1024;

      // Call the API with the media upload, defer so it doesn't immediately return.
      $client->setDefer(true);
      $request = $service->files->insert($file);

      // Create a media file upload to represent our upload process.
      $media = new Google_Http_MediaFileUpload(
      $client,
      $request,
      'text/plain',
      null,
      true,
      $chunkSizeBytes
      );
      $media->setFileSize(filesize(TESTFILE));

      // Upload the various chunks. $status will be false until the process is
      // complete.
      $status = false;
      $handle = fopen(TESTFILE, "rb");
      while (!$status && !feof($handle)) {
        $chunk = fread($handle, $chunkSizeBytes);
        $status = $media->nextChunk($chunk);
      }
      //Here you will get the new created folder's id
      echo "<pre>";
      var_dump($status->id);
      exit;
}
