* Validará que el `item_id` sea del tipo `int` para requests `GET` y `PUT`.
    * Si no lo es, el cliente verá un error útil y claro.
* Revisa si hay un parámetro de query opcional llamado `q` (como en `http://127.0.0.1:8000/items/foo?q=somequery`) para requests `GET`.
    * Como el parámetro `q` está declarado con `= None`, es opcional.
    * Sin el `None` sería requerido (como lo es el body en el caso con `PUT`).

    * Если это не так, клиент увидит полезную понятную ошибку.
* Проверять, есть ли необязательный параметр запроса с именем `q` (например, `http://127.0.0.1:8000/items/foo?q=somequery`) для `GET` HTTP-запросов.
    * Поскольку параметр `q` объявлен с `= None`, он необязателен.
    * Без `None` он был бы обязательным (как тело запроса в случае с `PUT`).

    * Si ce n'est pas le cas, le client verra une erreur utile et claire.
* Vérifier s'il existe un paramètre de requête optionnel nommé `q` (comme dans `http://127.0.0.1:8000/items/foo?q=somequery`) pour les requêtes `GET`.
    * Comme le paramètre `q` est déclaré avec `= None`, il est optionnel.
    * Sans le `None`, il serait requis (comme l'est le corps dans le cas de `PUT`).
