Caching Access Tokens

By default the library will use a simple in-memory caching implementation, however it is possible to override this behavior by passing a PSR-6 caching implementation in to the desired client., _(*19)

The following example takes advantage of Symfony's Cache Component., _(*20)

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;
use Symfony\Component\Cache\Adapter\ArrayAdapter;

// Please take the proper precautions when storing your access tokens in a cache no matter the implementation.
$cache = new ArrayAdapter();

$storage = new StorageClient([
    'authCache' => $cache
]);

Versioning

This library follows Semantic Versioning., _(*21)

Please note it is currently under active development. Any release versioned 0.x.y is subject to backwards incompatible changes at any time., _(*22)

GA: Libraries defined at a GA quality level are stable, and will not introduce backwards-incompatible changes in any minor or patch releases. We will address issues and requests with the highest priority., _(*23)

Beta: Libraries defined at a Beta quality level are expected to be mostly stable and we're working towards their release candidate. We will address issues and requests with a higher priority., _(*24)

Alpha: Libraries defined at an Alpha quality level are still a work-in-progress and are more likely to get backwards-incompatible updates., _(*25)

Contributing

Contributions to this library are always welcome and highly encouraged., _(*26)

See CONTRIBUTING for more information on how to get started., _(*27)
