Yii 2 path to frontend and backend

Question

I need to add/register a css file but I cant get the path to the frontend ;

What's the Yii Yii::app()->baseUrl equivalent in Yii 2 ?

I tryed:

Yii::$app->basePath and it gives me : c:/wamp/www/project/frontend

I only need /project/frontend

Answer 1

Yii 2中的Yii :: app（）-> baseUrl等效为

  \Yii::$app->request->BaseUrl

Answer 2

try this

   $baseUrl = Yii::app()->getBaseUrl(true);
   $scriptUrl = Yii::app()->request->scriptUrl;
   $themeUrl = Yii::app()->theme->getBaseUrl();
