Buzz Adapter (deprecated)

This adapter only implements the PHP-HTTP synchronous interface. This interface has been superseded by PSR-18, which the Buzz HTTP client implements directly.


To install the Buzz adapter, which will also install Buzz itself (if it was not yet included in your project), run:

$ composer require php-http/buzz-adapter


Begin by creating a Buzz client, you may pass any listener or configuration parameters to it like:

use Buzz\Browser;
use Buzz\Client\Curl;
use Buzz\Listener\CookieListener;

$browser = new Browser();

$client = new Curl();

// Create CookieListener
$listener = new CookieListener();

Then create the adapter:

use Http\Adapter\Buzz\Client as BuzzAdapter;
use Http\Message\MessageFactory\GuzzleMessageFactory;

$adapter = new BuzzAdapter($browser, new GuzzleMessageFactory());

Or relying on discovery:

use Http\Adapter\Buzz\Client as BuzzAdapter;

$adapter = new BuzzAdapter($browser);

Be Aware

This adapter violates the Liskov substitution principle in a rare edge case. When the adapter is configured to use Buzz’ Curl client, it does not send request bodies for request methods such as GET, HEAD and TRACE. A RequestException will be thrown if this ever happens.

If you need GET request with a body (e.g. for Elasticsearch) you need to use the Buzz FileGetContents client or choose a different HTTPlug client like Guzzle 6.
