# Request e classe APIRoute personalizadas { #custom-request-and-apiroute-class }

Em alguns casos, você pode querer sobrescrever a lógica usada pelas classes `Request` e `APIRoute`.

Em particular, isso pode ser uma boa alternativa para uma lógica em um middleware.

Por exemplo, se você quiser ler ou manipular o corpo da requisição antes que ele seja processado pela sua aplicação.

/// danger | Cuidado

Isso é um recurso "avançado".

# Request Formları ve Dosyalar { #request-forms-and-files }

`File` ve `Form` kullanarak aynı anda hem dosyaları hem de form alanlarını tanımlayabilirsiniz.

/// info | Bilgi

Yüklenen dosyaları ve/veya form verisini almak için önce [`python-multipart`](https://github.com/Kludex/python-multipart) paketini kurun.

Bir [sanal ortam](../virtual-environments.md) oluşturduğunuzdan, onu aktive ettiğinizden ve ardından paketi kurduğunuzdan emin olun, örneğin:

# Custom Request and APIRoute class { #custom-request-and-apiroute-class }

In some cases, you may want to override the logic used by the `Request` and `APIRoute` classes.

In particular, this may be a good alternative to logic in a middleware.

For example, if you want to read or manipulate the request body before it is processed by your application.

/// danger

This is an "advanced" feature.

# 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.
