## Ek Header'ları Yasaklayın { #forbid-extra-headers }

Bazı özel kullanım senaryolarında (muhtemelen çok yaygın değil), kabul etmek istediğiniz header'ları **kısıtlamak** isteyebilirsiniz.

Pydantic'in model yapılandırmasını kullanarak `extra` alanları `forbid` edebilirsiniz:

## Заборона зайвих параметрів запиту { #forbid-extra-query-parameters }

У деяких особливих випадках (ймовірно, не дуже поширених) Ви можете захотіти **обмежити** параметри запиту, які дозволено отримувати.

Ви можете використати конфігурацію моделі Pydantic, щоб заборонити (`forbid`) будь-які зайві (`extra`) поля:

Em alguns casos especiais (provavelmente não muito comuns), você queira **restringir** os parâmetros de consulta que deseja receber.

Você pode usar a configuração do modelo Pydantic para `forbid` qualquer campo `extra`:
