Try This :

public static function allowedDomains()
{
    return [
        // '*',                        // star allows all domains
        'http://localhost:3000',
        'http://test2.example.com',
    ];
}  



public function behaviors()
    {
        return array_merge(parent::behaviors(), [

            // For cross-domain AJAX request
            'corsFilter'  => [
                'class' => \yii\filters\Cors::className(),
                'cors'  => [
                    // restrict access to domains:
                    'Origin'                           => static::allowedDomains(),
                    'Access-Control-Request-Method'    => ['POST'],
                    'Access-Control-Allow-Credentials' => true,
                    'Access-Control-Max-Age'           => 3600,                 // Cache (seconds)

                ],
            ],

        ]);
    }

Add This Function on your controller .

And One Thing angular2 use OPTION method at the first time For so allow OPTION method also
