Features

Acquires access tokens via one of the supported grant types (code, client credentials, user credentials, refresh token). Or you can set an access token yourself.
Supports refresh tokens (stores them and uses them to get new access tokens).
Handles token expiration (acquires new tokens and retries failed requests).

Running the tests

First make sure you have all the dependencies in place by running composer install --prefer-dist, then simply run .vendor/bin/phpunit., _(*7)

Example

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;
use Sainsburys\Guzzle\Oauth2\GrantType\RefreshToken;
use Sainsburys\Guzzle\Oauth2\GrantType\PasswordCredentials;
use Sainsburys\Guzzle\Oauth2\Middleware\OAuthMiddleware;

$baseUri = 'https://example.com';
$config = [
    PasswordCredentials::CONFIG_USERNAME => 'test@example.com',
    PasswordCredentials::CONFIG_PASSWORD => 'test password',
    PasswordCredentials::CONFIG_CLIENT_ID => 'test-client',
    PasswordCredentials::CONFIG_TOKEN_URL => '/oauth/token',
    'scope' => 'administration',
];

$oauthClient = new Client(['base_uri' => $baseUri]);
$grantType = new PasswordCredentials($oauthClient, $config);
$refreshToken = new RefreshToken($oauthClient, $config);
$middleware = new OAuthMiddleware($oauthClient, $grantType, $refreshToken);

$handlerStack = HandlerStack::create();
$handlerStack->push($middleware->onBefore());
$handlerStack->push($middleware->onFailure(5));

$client = new Client(['handler'=> $handlerStack, 'base_uri' => $baseUri, 'auth' => 'oauth2']);

$response = $client->request('GET', '/api/user/me');

// Use $middleware->getAccessToken(); and $middleware->getRefreshToken() to get tokens
// that can be persisted for subsequent requests.
