[SOLVED] Getting base URL in Yii 2

Getting base URL in Yii 2

I am trying to get the base URL for the project in Yii 2 but it doesn't seem to work. According to this page you used to be able to do:

Yii::app()->getBaseUrl(true);

In Yii 1, but it seems that that method in Yii 2 no longer accepts a parameter?

I've tried doing it without true, such as:

Yii::$app->getBaseUrl();

But it just returns empty.

How can you do this in Yii 2?

Solution

To get base URL of application you should use yii\helpers\Url::base() method:

use yii\helpers\Url;

Url::base();         // /myapp
Url::base(true);     // http(s)://example.com/myapp - depending on current schema
Url::base('https');  // https://example.com/myapp
Url::base('http');   // http://example.com/myapp
Url::base('');       // //example.com/myapp

Url::home() should NOT be used in this case. Application::$homeUrl uses base URL by default, but it could be easily changed (for example to https://example.com/myapp/home) so you should not rely on assumption that it will always return base URL. If there is a special Url::base() method to get base URL, then use it.
