How to make an absolute link in yii2?

Question

Yii

I make a link in the backend to the frontend

<?=Html::a('Просмотр', Url::to([Yii::$app->urlManager->hostInfo . '/post/view' , 'slug' => $model->slug], true))?>

And it turns out such a link site.ku/admin/http://site.ku/post/view?slug=pervaa...

Answer 1

Add a second urlManager to the backend config:

'urlManager' => [
        //...
],
'frontUrlManager' => [
        'class' => 'yii\web\UrlManager',
        'baseUrl' => '',
        //...
]

and then use
For convenience, the array with the rules can be taken out as separate files and connected later in the front config and in the back config
