Yii 2.0 How to extend Core Classes

Yii 2.0 General Discussions

I want to extend the class yii\web\Response. So I created a new class Response in the folder components and I try to overwrite the send method.




    namespace app\components;


    use Yii;


    class Response extends \yii\web\Response{


	    public function init(){

		    parent::init();

	    }

	

	    /**

	     * Sends the response to the client.

	     */

	    public function send()

	    { ...

Finally I tried to import my new Response-Class by importing it in the config.




    $config = [

        'id' => 'basic',

        'basePath' => dirname(__DIR__),

        'bootstrap' => ['log'],

        'components' => [

            'import'  => [

            	'class' => 'app\components\Response',		

            ],

Why is it not going to work like this?

Not completly sure since I have not overwritten any core-class so far.

But after a look at:

http://www.yiiframework.com/doc-2.0/yii-web-response.html

I think it should be:




'components' => [

	'respone'  => [

		'class' => 'app\components\Response',           

	],

]

For my understanding you are then able to use it like:




\Yii::$app->response->send();

Also I think - WHEN you have use statements of the Reponse class somewhere in your files - you have to change the use statement to:




// from

// use yii\web\Response; 


// to

use app\components\Response;

you delare it as ‘import’ so locator will put it as \Yii:$app->import
