## 🔬 `File` &amp; `Form` 🔢

!!! warning "Внимание"
    Вы можете объявить несколько параметров `File` и `Form` в операции *path*, но вы не можете также объявить поля `Body`, которые вы ожидаете получить в виде JSON, так как запрос будет иметь тело, закодированное с помощью `multipart/form-data` вместо `application/json`.

    Это не ограничение **Fast API**, это часть протокола HTTP.

Se você não se importa com qualquer um desses termos e só precisa adicionar segurança com autenticação baseada em usuário e senha _agora_, pule para os próximos capítulos.

## OAuth2

OAuth2 é uma especificação que define várias formas para lidar com autenticação e autorização.

Ela é bastante extensiva na especificação e cobre casos de uso muito complexos.

Ela inclui uma forma para autenticação usando “third party”/aplicações de terceiros.
