Usage

To use this extension, simply add the behaviors for your base controller:

use yii\helpers\ArrayHelper;
use yii\filters\auth\HttpBearerAuth;
use yii\filters\auth\QueryParamAuth;
use filsh\yii2\oauth2server\filters\ErrorToExceptionFilter;
use filsh\yii2\oauth2server\filters\auth\CompositeAuth;

class Controller extends \yii\rest\Controller
{
    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return ArrayHelper::merge(parent::behaviors(), [
            'authenticator' => [
                'class' => CompositeAuth::className(),
                'authMethods' => [
                    ['class' => HttpBearerAuth::className()],
                    ['class' => QueryParamAuth::className(), 'tokenParam' => 'accessToken'],
                ]
            ],
            'exceptionFilter' => [
                'class' => ErrorToExceptionFilter::className()
            ],
        ]);
    }
}

To get access token (js example):

var url = window.location.host + "/oauth2/token";
var data = {
    'grant_type':'password',
    'username':'<some login from your user table>',
    'password':'<real pass>',
    'client_id':'testclient',
    'client_secret':'testpass'
};
//ajax POST `data` to `url` here
//
