Script to read all files shared with an especific service account

Requirements

1- PHP 5.4 or greater with the command-line interface (CLI) and JSON extension installed.

2- The Composer dependency management tool.

3- Google Cloud Platform project with the Drive API enabled.

4- A Service Account for the Google Cloud Platform project.

Installation

Composer

The preferred method is via composer. Follow the installation instructions if you do not already have composer installed.

Once composer is installed, execute the following command in your project root to install this library:

composer require google/apiclient:"^2.0"

Finally, be sure to include the autoloader:

require_once '/path/to/your-project/vendor/autoload.php';

Credentials of the Service Account

Copy the credential json file as 'serviceAccountCredentials.json' in root folder.

Use

php readSharedWithMe.php;

If everything goes well, a folder will be created with the exact jerarchy including all folders that had been shared in Google Drive with the service account email address. This last statement needs to be taken into consideration carefully: The Folders to be shared need to be done to the "service account email address", not to the user owning the project (or the service account for that matter).

When Sharing a Folder jerarchy it's only needed to share the root folder, not the contained ones (or it's files).

E.G.:

Folder 1 (Shared with the service account email) | File 1 (No need for sharing) |________________ | | Folder 2 Folder 3 (No need for sharing) | File 2 (No need for sharing) File 3 (No need for sharing)

TODO

Make it a class and publish it in https://packagist.org (follow https://www.w3resource.com/php/composer/create-publish-and-use-your-first-composer-package.php)

Improve usage documentation (how to create project in google cloud, service account, etc.)
