# Google Cloud Storage filesystem driver for Laravel [](https://packagist.org/packages/spatie/laravel-google-cloud-storage) [](https://github.com/spatie/laravel-google-cloud-storage/actions/workflows/run-tests.yml) [](https://packagist.org/packages/spatie/laravel-google-cloud-storage) --- Google Cloud Storage filesystem driver for Laravel 9 (using Flysystem v3 and its own GCS adapter). **Looking for Laravel 8 support? Use the `v1` branch!** ## Support us [<img src="https://github-ads.s3.eu-central-1.amazonaws.com/laravel-google-cloud-storage.jpg?t=1" width="419px" />](https://spatie.be/github-ad-click/laravel-google-cloud-storage) We invest a lot of resources into creating [best in class open source packages](https://spatie.be/open-source). You can support us by [buying one of our paid products](https://spatie.be/open-source/support-us). We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on [our contact page](https://spatie.be/about-us). We publish all received postcards on [our virtual postcard wall](https://spatie.be/open-source/postcards). ## Installation You can install the package via composer: ```bash composer require spatie/laravel-google-cloud-storage ``` Next, add a new disk to your `filesystems.php` config: ```php 'gcs' => [ 'driver' => 'gcs', 'key_file_path' => env('GOOGLE_CLOUD_KEY_FILE', null), // optional: /path/to/service-account.json 'key_file' => [], // optional: Array of data that substitutes the .json file (see below) 'project_id' => env('GOOGLE_CLOUD_PROJECT_ID', 'your-project-id'), // optional: is included in key file 'bucket' => env('GOOGLE_CLOUD_STORAGE_BUCKET', 'your-bucket'), 'path_prefix' => env('GOOGLE_CLOUD_STORAGE_PATH_PREFIX', ''), // optional: /default/path/to/apply/in/bucket 'storage_api_uri' => env('GOOGLE_CLOUD_STORAGE_API_URI', null), // see: Public URLs below 'api_endpoint' => env('GOOGLE_CLOUD_STORAGE_API_ENDPOINT', null), // set storageClient apiEndpoint 'visibility' => 'public', // optional: public|private 'visibility_handler' => null, // optional: set to \League\Flysystem\GoogleCloudStorage\UniformBucketLevelAccessVisibility::class to enable uniform bucket level access 'metadata' => ['cacheControl' => 'public,max-age=86400'], // optional: default metadata ], ``` ## Usage ```php $disk = Storage::disk('gcs'); $disk->put('avatars/1', $fileContents); $exists = $disk->exists('file.jpg'); $time = $disk->lastModified('file1.jpg'); $disk->copy('old/file1.jpg', 'new/file1.jpg'); $disk->move('old/file1.jpg', 'new/file1.jpg'); $url = $disk->url('folder/my_file.txt'); $url = $disk->temporaryUrl('folder/my_file.txt', now()->addMinutes(30)); $disk->setVisibility('folder/my_file.txt', 'public'); ``` See https://laravel.com/docs/master/filesystem for full list of available functionality. ### Authentication The Google Client uses a few methods to determine how it should authenticate with the Google API. 1. If you specify a path in the key `key_file` in disk config, that json credentials file will be used. 2. If the `GOOGLE_APPLICATION_CREDENTIALS` env var is set, it will use that. ```php putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json'); ``` 3. It will then try load the key file from a 'well known path': * windows: %APPDATA%/gcloud/application_default_credentials.json * others: $HOME/.config/gcloud/application_default_credentials.json 4. If running in **Google App Engine**, the built-in service account associated with the application will be used. 5. If running in **Google Compute Engine**, the built-in service account associated with the virtual machine instance will be used. 6. If you want to authenticate directly without using a json file, you can specify an array for `key_file` in disk config with this data: ```php 'key_file' => [ 'type' => env('GOOGLE_CLOUD_ACCOUNT_TYPE'), 'private_key_id' => env('GOOGLE_CLOUD_PRIVATE_KEY_ID'), 'private_key' => env('GOOGLE_CLOUD_PRIVATE_KEY'), 'client_email' => env('GOOGLE_CLOUD_CLIENT_EMAIL'), 'client_id' => env('GOOGLE_CLOUD_CLIENT_ID'), 'auth_uri' => env('GOOGLE_CLOUD_AUTH_URI'), 'token_uri' => env('GOOGLE_CLOUD_TOKEN_URI'), 'auth_provider_x509_cert_url' => env('GOOGLE_CLOUD_AUTH_PROVIDER_CERT_URL'), 'client_x509_cert_url' => env('GOOGLE_CLOUD_CLIENT_CERT_URL'), ], ``` ### Public URLs The adapter implements a `getUrl($path)` method which returns a public url to a file. >**Note:** Method available for Laravel 5.2 and higher. If used on 5.1, it will throw an exception. ```php $disk = Storage::disk('gcs'); $url = $disk->url('folder/my_file.txt'); // http://storage.googleapis.com/bucket-name/folder/my_file.txt ``` If you configure a `path_prefix` in your config: ```php $disk = Storage::disk('gcs'); $url = $disk->url('folder/my_file.txt'); // http://storage.googleapis.com/bucket-name/path-prefix/folder/my_file.txt ``` If you configure a custom `storage_api_uri` in your config: ```php $disk = Storage::disk('gcs'); $url = $disk->url('folder/my_file.txt'); // http://your-custom-domain.com/bucket-name/path-prefix/folder/my_file.txt ``` For a custom domain (storage api uri), you will need to configure a CNAME DNS entry pointing to `storage.googleapis.com`. Please see https://cloud.google.com/storage/docs/xml-api/reference-uris#cname for further instructions. ### Temporary / Signed URLs With the latest adapter versions, you can easily generate a signed URLs for files that are not publicly visible by default. ```php $disk = Storage::disk('gcs'); $url = $disk->temporaryUrl('folder/my_file.txt', now()->addMinutes(30)); // https://storage.googleapis.com/test-bucket/folder/my_file.txt?GoogleAccessId=test-bucket%40test-gcp.iam.gserviceaccount.com&Expires=1571151576&Signature=tvxN1OS1txkWAUF0cCR3FWK%seRZXtFu42%04%YZACYL2zFQxA%uwdGEmdO1KgsHR3vBF%I9KaEzPbl4b7ic2IWUuo8Jh3IoZFqdTQec3KypjDtt%02DGwm%OO6pWDVV421Yp4z520%o5oMqGBtV8B3XmjW2PH76P3uID2QY%AlFxn23oE9PBoM2wXr8pDXhMPwZNJ0FtckSc26O8PmfVsG7Jvln%CQTU57IFyB7JnNxz5tQpc2hPTHbCGrcxVPEISvdOamW3I%83OsXr5raaYYBPcuumDnAmrK%cyS9%Ky2fL2B2shFO2cz%KRu79DBPqtnP2Zf1mJWBTwxVUCK2jxEEYcXBXtdOszIvlI6%tp2XfVwYxLNFU ``` ## Uniform bucket-level access Google Cloud Storage allows setting permissions at the bucket level i.e. "Uniform bucket-level access". Initially, the error "Cannot insert legacy ACL for an object when uniform bucket-level access is enabled" is observed. When uploading files to such buckets ensure the `visibility_handler` within the configuration file is set as follows: ```php 'visibility_handler' => \League\Flysystem\GoogleCloudStorage\UniformBucketLevelAccessVisibility::class, ``` Please see https://cloud.google.com/storage/docs/access-control/signed-urls and https://laravel.com/docs/6.x/filesystem for more info. ## Testing ```bash composer test ``` ## Changelog Please see [CHANGELOG](CHANGELOG.md) for more information on what has changed recently. ## Contributing Please see [CONTRIBUTING](https://github.com/spatie/.github/blob/main/CONTRIBUTING.md) for details. ## Security Vulnerabilities Please review [our security policy](../../security/policy) on how to report security vulnerabilities. ## Credits - [Superbalist](https://github.com/Superbalist) for the original GCS adapter package - [Alex Vanderbist](https://github.com/alexvanderbist) - [All Contributors](../../contributors) ## License The MIT License (MIT).
