google 驱动器 file.list 查询 returns 子文件夹 ID 为 false - php

Question

我可以使用以下函数列出位于 google 驱动器根目录中的文件夹中的项目。但是当我尝试列出位于父文件夹内的子文件夹中的项目时（父文件夹位于 google 驱动器的根目录中）

[PARENT FOLDER] //the 'sub folder' and 'other files' are getting listed
       └------[SUB FOLDER] //query is returned false when i try to put this folder ID as parent
       |            └--------[FILE LOCATED INSIDE SUB FOLDER]
       └------[OTHER FILES]

用于列出来自 google 驱动器的文件的函数：


function listFilesFolders($client, $search, $subFolderId){

        $service = new Google_Service_Drive($client);

        //ID of the folder located in root of google drive
        //works fine if i run the query with this ID
        $superParentId = '1Xky058b134vadgSOyD-ADFagaGAGAdgha'; 

        //properly working query
        //$query = "'".$superParentId."' in parents and trashed = false"; 

        //query that runs for the subfolder located inside the parent folder ($superParentId)
        $query = "'".$subFolderId."' in parents and trashed = false"; 

        $optParams = array('q' => $query);

        // Returns the list of files and folders as object
        $results = $service->files->listFiles($optParams);

        // Return false if nothing is found
        if (count($results->getFiles()) == 0) {
            return false;
        }

        // Converting array to object
        $result = array();
        foreach ($results->getFiles() as $file) {
            $result[$file->getId()] = $file->getName();
        }

        return $result;
}

我可以知道如何列出子文件夹中的文件吗？

谢谢，

你需要做两件事

找出超级父文件夹中的哪些文件是子文件夹您可以使用修改后的查询来完成：

$query2 = "'$superParentId' in parents and trashed = false and mimeType='application/vnd.google-apps.folder'";
...

循环列出这些子文件夹中包含的文件

...
$query3 = "'$subFolderId' in parents and trashed = false";
...

google 驱动器 file.list 查询 returns 子文件夹 ID 为 false - php

google drive file.list query returns false for sub-folder ID - php
