# Користувацькі класи Request та APIRoute { #custom-request-and-apiroute-class }

У деяких випадках ви можете захотіти перевизначити логіку, яку використовують класи `Request` та `APIRoute`.

Зокрема, це може бути доброю альтернативою логіці в проміжному програмному забезпеченні.

Наприклад, якщо потрібно прочитати або змінити тіло запиту до того, як його обробить ваш застосунок.

/// danger | Обережно

Це «просунута» можливість.

# Özel Request ve APIRoute sınıfı { #custom-request-and-apiroute-class }

Bazı durumlarda, `Request` ve `APIRoute` sınıflarının kullandığı mantığı override etmek isteyebilirsiniz.

Özellikle bu yaklaşım, bir middleware içindeki mantığa iyi bir alternatif olabilir.

Örneğin, request body uygulamanız tarafından işlenmeden önce okumak veya üzerinde değişiklik yapmak istiyorsanız.

/// danger | Uyarı

Bu "ileri seviye" bir özelliktir.
