### `UploadFile` { #uploadfile }

`UploadFile` tiene los siguientes atributos:

* `filename`: Un `str` con el nombre original del archivo que fue subido (por ejemplo, `myimage.jpg`).
* `content_type`: Un `str` con el tipo de contenido (MIME type / media type) (por ejemplo, `image/jpeg`).

Eğer `Authorization` header’ını görmezse ya da değer `Bearer ` token’ı içermiyorsa, doğrudan 401 status code hatasıyla (`UNAUTHORIZED`) response döner.

Token’ın var olup olmadığını kontrol edip ayrıca hata döndürmenize bile gerek yoktur. Fonksiyonunuz çalışıyorsa, token içinde bir `str` olacağından emin olabilirsiniz.

Для цього ми оновлюємо Pydantic-модель `TokenData` новою властивістю `scopes`.

Валідувавши дані через Pydantic, ми гарантуємо, що, наприклад, маємо саме `list` із `str` для scopes і `str` для `username`.

Замість, наприклад, `dict` або чогось іншого, що може зламати застосунок далі, створивши ризик безпеки.
