A Hawk Authenticator for Guzzle.

Originally developed by jeskew, this extremely simple Plugin provides middleware you can place on your Guzzle client to automagically sign your requests.

Usage

First, install with Composer:

composer require complex-media/guzzle-hawk

Then, use it in code.

use ComplexMedia\Guzzle\Plugin\Hawk;
use GuzzleHttp\Client as Guzzle;

$client = new Guzzle();
$signer = new Hawk($key, $secret, $algorithm, $offset);

$client->getEmitter()->attach($signer);
$response = $client->get($URL);

$algorithm will default to 'sha256', but you can set it to whatever your system supports. $offset adds a clock skew to synchronize with your server, and defaults to 0. If you get a 401 from your server, you can adjust several properties on the signer and try again immediately:

$signer->key = $new_key
$signer->secret = $new_secret
$signer->algorithm = $new_algorithm
$signer->offset = $new_offset

$response = $client->get($URL);
