Guzzle Cache

Provides a Drupal cache backend for Kevinrob/guzzle-cache-middleware.

Usage

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use Kevinrob\GuzzleCache\CacheMiddleware;
use Kevinrob\GuzzleCache\Strategy\PrivateCacheStrategy;
use Drupal\guzzle_cache\DrupalGuzzleCache;

// Create default HandlerStack
$stack = HandlerStack::create();

// Create a Drupal Guzzle cache. Its' useful to have a separate cache bin to
// manage independent of other cache bins. Here is how you might define such a
// cache bin in a *.service.yml file:
// cache.my_custom_http_cache_bin:
//   class: Drupal\Core\Cache\CacheBackendInterface
//   tags:
//     - { name: cache.bin }
//   factory: cache_factory:get
//   arguments: [my_custom_http_cache_bin]
$cache = new DrupalGuzzleCache(\Drupal::service('cache.my_custom_http_cache_bin'));

// Push the cache to the stack.
$stack->push(
  new CacheMiddleware(
    new PrivateCacheStrategy($cache)
  ),
  'cache'
);

// Initialize the client with the handler option
$client = new Client(['handler' => $stack]);

// Fetch the URI cached if available.
$response = $client->request('GET', 'http://www.example.com/');
