Google Cloud Auth
=================

[](#google-cloud-auth)

![TravisCI]()![Maintainability]()![Test Coverage]()

GCloud Auth is a PHP Experts, Inc., Project for authenticating with Google Cloud API without needing the huge gcloud binary.

As of April 2025, the `google-cloud-cli` weighs in at around 150 MB, not counting dependencies, and over 550 MB counting dependencies, on modern Linux systems.

Using the `google/apiclient` composer package itself weighs in at 141 MB.

This project, by comparison, weighs in around 10 KB (or 15,000x smaller).

It provides everything you need to retrieve an OAuth2 token for authenticating with Google Cloud API services. It autogenerates the JWT token necessary for this, using ext-openssl.

It includes a drop-in `phpexperts/rest-speaker` `GoogleAuth` driver, but it can also be used standalone by any PHP project.

Installation
------------

[](#installation)

Via Composer

```
composer require phpexperts/gcloud-auth
```

Usage
-----

[](#usage)

For use with `phpexperts/rest-speaker`:

```
use PHPExperts\GoogleCloudAuth\GoogleCloudAuth;
use PHPExperts\RESTSpeaker\RESTSpeaker;

$api = new RESTSpeaker(new GoogleCloudAuth('relative/path/to/services.json'));
```

For use with any other PHP project:

```
use PHPExperts\GoogleCloudAuth\GoogleCloudAuth;
$gcloudAuth = new GoogleCloudAuth('relative/path/to/services.json');

// Returns the raw Oauth2Token as a string.
$gcloudOauth2Token = $gcloudAuth->obtainGCloudOauthToken();

$url = "https://storage.googleapis.com/storage/v1/b?project=$projectId";
$http = new \GuzzleHttp\Client([
    'headers' => [
        'Content-Type'  => 'application/json',
        'Authorization' => "Bearer $gcloudOauth2Token",
    ]
]);
$response = $http->get($url);
```
