Silex Service Provider OAuth

This is an UiTID OAuth 1.0 webservice authentication provider for the Silex SecurityServiceProvider.

Usage

There's a demo application which shows you how to integrate & configure this component.

First register the provider in your Silex application. Supply the base url of the desired UiTID API environment, and an OAuth consumer key & secret that are allowed to access the UiTID Credentials API.

$app->register(
    new \CultuurNet\SilexServiceProviderOAuth\OAuthServiceProvider(),
    array(
        'oauth.fetcher.base_url' => 'http://acc2.uitid.be',
        'oauth.fetcher.consumer' => array(
            'key' => 'notsosecretkey',
            'secret' => 'verysecret',
        ),
    )
);

Define a service named oauth.model.provider.nonce_provider that implements CultuurNet\SymfonySecurityOAuth\Model\Provider\NonceProviderInterface. The cultuurnet/symfony-security-oauth-redis package provides an implementation that used Redis for storage. It uses the predis PHP client library for Redis. However, you are free to use your own implementation for a suitable storage mechanism.

$app['predis.client'] = $app->share(
    function () {
        return new \Predis\Client('tcp://127.0.0.1:6379');
    }
);

$app['oauth.model.provider.nonce_provider'] = $app->share(
    function (\Silex\Application $app) {
        return new \CultuurNet\SymfonySecurityOAuthRedis\NonceProvider(
            $app['predis.client']
        );
    }
);

Then configure a firewall to make use of the oauth authentication provider:

$app->register(
  new \Silex\Provider\SecurityServiceProvider(),
  array(
      'security.firewalls' => array(
          'myapi' => array(
              'pattern' => '^/my/api/.*',
              'oauth' => true,
              'stateless' => true,
           ),
      ),
  )
);

For improved performance, you can cache the tokens retrieved from the UiTID Credentials API. The best way to do this is by wrapping the original oauth.model.provider.token_provider service in a decorator that implements the same interface and takes care of caching. Again, you are free to use your own implementation for a suitable storage mechanism. The cultuurnet/symfony-security-oauth-redis package provides an implementation that used Redis.

$app->extend(
    'oauth.model.provider.token_provider',
    function (
        \CultuurNet\SymfonySecurityOAuth\Model\Provider\TokenProviderInterface $tokenProvider,
        \Silex\Application $app
    ) {
        return new \CultuurNet\SymfonySecurityOAuthRedis\TokenProviderCache(
            $tokenProvider,
            $app['predis.client']
        );
    }
);
