Google uses unique IDs for each folder and file. This makes it difficult to integrate with other storage services which use normal paths. This Flysystem adapter works around that problem by seamlessly translating paths from “display paths” to “virtual paths”, and vice versa.

For example, virtual path /Xa3X9GlR6EmbnY1RLVTk5VUtOVkk/0B3X9GlR6EmbnY1RLVTk5VUtOVkk becomes /My Nice Dir/myFile.ext and all ID handling is hidden.

Installation

For Flysystem V2/V3 or Laravel >= 9.x.x

composer require masbug/flysystem-google-drive-ext

For Flysystem V1 or Laravel <= 8.x.x use 1.x.x version of the package

composer require masbug/flysystem-google-drive-ext:"^1.0.0"

Getting Google Keys

Please follow Google Docs to obtain your client ID, client secret & refresh token.

Usage with Laravel

Update .env file with google keys
Add the keys you created to your .env file and set google as your default cloud storage. You can copy the .env.example file and fill in the blanks.

FILESYSTEM_CLOUD=google
GOOGLE_DRIVE_CLIENT_ID=xxx.apps.googleusercontent.com
GOOGLE_DRIVE_CLIENT_SECRET=xxx
GOOGLE_DRIVE_REFRESH_TOKEN=xxx
GOOGLE_DRIVE_FOLDER=
#GOOGLE_DRIVE_TEAM_DRIVE_ID=xxx

# you can use more accounts, only add more configs
#SECOND_GOOGLE_DRIVE_CLIENT_ID=xxx.apps.googleusercontent.com
#SECOND_GOOGLE_DRIVE_CLIENT_SECRET=xxx
#SECOND_GOOGLE_DRIVE_REFRESH_TOKEN=xxx
#SECOND_GOOGLE_DRIVE_FOLDER=backups
#SECOND_DRIVE_TEAM_DRIVE_ID=xxx

Add disks on config/filesystems.php

'disks' => [
    // ...
    'google' => [
        'driver' => 'google',
        'clientId' => env('GOOGLE_DRIVE_CLIENT_ID'),
        'clientSecret' => env('GOOGLE_DRIVE_CLIENT_SECRET'),
        'refreshToken' => env('GOOGLE_DRIVE_REFRESH_TOKEN'),
        'folder' => env('GOOGLE_DRIVE_FOLDER'), // without folder is root of drive or team drive
        //'teamDriveId' => env('GOOGLE_DRIVE_TEAM_DRIVE_ID'),
    ],
    // you can use more accounts, only add more disks and configs on .env
    // also you can use the same account and point to a diferent folders for each disk
    /*'second_google' => [
        'driver' => 'google',
        'clientId' => env('SECOND_GOOGLE_DRIVE_CLIENT_ID'),
        'clientSecret' => env('SECOND_GOOGLE_DRIVE_CLIENT_SECRET'),
        'refreshToken' => env('SECOND_GOOGLE_DRIVE_REFRESH_TOKEN'),
        'folder' => env('SECOND_GOOGLE_DRIVE_FOLDER'),
    ],*/
    // ...
],

Add driver storage in a ServiceProvider on path app/Providers/

For Example:

namespace App\Providers;

use Illuminate\Support\Facades\Storage;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider { // can be a custom ServiceProvider
    // ...
    public function boot(){
        // ...
        try {
            \Storage::extend('google', function($app, $config) {
                $options = [];

                if (!empty($config['teamDriveId'] ?? null)) {
                    $options['teamDriveId'] = $config['teamDriveId'];
                }

                $client = new \Google\Client();
                $client->setClientId($config['clientId']);
                $client->setClientSecret($config['clientSecret']);
                $client->refreshToken($config['refreshToken']);
                
                $service = new \Google\Service\Drive($client);
                $adapter = new \Masbug\Flysystem\GoogleDriveAdapter($service, $config['folder'] ?? '/', $options);
                $driver = new \League\Flysystem\Filesystem($adapter);

                return new \Illuminate\Filesystem\FilesystemAdapter($driver, $adapter);
            });
        } catch(\Exception $e) {
            // your exception handling logic
        }
        // ...
    }
    // ...
}

Now you can access the drives like so:

$googleDisk = Storage::disk('google');
//$secondDisk = Storage::disk('second_google'); //others disks

Keep in mind that there can only be one default cloud storage drive, defined by FILESYSTEM_CLOUD in your .env (or config) file. If you set it to google, that will be the cloud drive:

Storage::cloud(); // refers to Storage::disk('google')
