Yii Slack extension

Yii extension for accessing Slack API in Yii framework via Guzzle.

Installation

Yii Slack is composer library so you can install the latest version with:

php composer.phar require tatarko/yii-slack

Configuration

To your application's config add following:

'components' => array(
	'slack' => array(
		'class' => 'Tatarko\\YiiSlack\\ApplicationComponent',
		'appId' => '', // Your's application ID
		'appSecret' => '', // Your's application secret code
		'tokenStateName' => 'slack.access.token'; // optional - change name of the user's state variable to store access token in
		'companyToken' => '', // optional - set global access token of your company's account to use slack component without user authentication
	),
)

For OAuth authentication add following method to the controller:

class SiteController extends Controller
{
	public function actions()
    {
        return array(
            'slack' => array(
                'class' => 'Tatarko\\YiiSlack\\AuthenticationAction',
				'onAuthSuccess' => function(CEvent $event) {
					// you can get $event->params->access_token and store it in some persistant database instead of user's states (that is basically sessions variable)
					$this->redirect('welcome');
				},
                'onAuthError' => function(CEvent $event) {
					// $event->params is instance of Exception (CException or GuzzleHttp\Exception\TransferException)
					$this->redirect('login');
				},
            ),
        );
    }
}

Usage

For simple OAuth just create link in any view file:

<a href="<?= $this->createUrl('site/slack') ?>">Login with Slack</a>

After that you can check if current web user is logged using Slack by calling:

var_dump(Yii::app()->slack->isAuthenticated); // boolean

And in case that user is really authenticated you can make API call like:

var_dump(Yii::app()->slack->get('auth.test'));

That prints something likes:

array(6) {
  'ok' =>
  bool(true)
  'url' =>
  string(25) "https://myteam.slack.com/"
  'team' =>
  string(7) "My Team"
  'user' =>
  string(3) "cal"
  'team_id' =>
  string(6) "T12345"
  'user_id' =>
  string(6) "U12345"
}

For additional arguments use:

Yii::app()->slack->post('channels.create', array('name' => 'mychannel'));

For complete list of all available methods and their arguments go to official Slack documentation.
