namespace app\controllers;

use app\models\LoginForm;

class AuthController extends \yii\web\Controller
{
public function behaviors()
{
return [
/**
* Checks oauth2 credentions and try to perform OAuth2 authorization on logged user.
* AuthorizeFilter uses session to store incoming oauth2 request, so
* you can do additional steps, such as third party oauth authorization (Facebook, Google ...)
*/
'oauth2Auth' => [
'class' => \yuncms\oauth2\AuthorizeFilter::className(),
'only' => ['index'],
],
];
}
public function actions()
{
return [
/**
* Returns an access token.
*/
'token' => [
'class' => \yuncms\oauth2\TokenAction::classname(),
],
/**
* OPTIONAL
* Third party oauth providers also can be used.
*/
'back' => [
'class' => \yii\authclient\AuthAction::className(),
'successCallback' => [$this, 'successCallback'],
],
];
}
/**
* Display login form, signup or something else.
* AuthClients such as Google also may be used
*/
public function actionIndex()
{
$model = new LoginForm();
if ($model->load(\Yii::$app->request->post()) && $model->login()) {
if ($this->isOauthRequest) {
$this->finishAuthorization();
} else {
return $this->goBack();
}
} else {
return $this->render('index', [
'model' => $model,
]);
}
}
/**
* OPTIONAL
* Third party oauth callback sample
* @param OAuth2 $client
*/
public function successCallback($client)
{
switch ($client::className()) {
case GoogleOAuth::className():
// Do login with automatic signup
break;
...
default:
break;
}
/**
* If user is logged on, redirects to oauth client with success,
* or redirects error with Access Denied
*/
if ($this->isOauthRequest) {
$this->finishAuthorization();
}
}

}
```

],
];
}
/**
