Call URL on Drupal 8, Like drupal_http_request() on D7

Example :

    use GuzzleHttp\Exception\RequestException;

    $url = "http://www.domail.com";

    $client = \Drupal::httpClient();

    try {

      $response = $client->get($url);

      $data = $response->getBody();

      $code = $response->getStatusCode();

      $header = $response->getHeaders();

    }

    catch (RequestException $e) {

      watchdog_exception('my_module', $e);

    }
