Файли будуть завантажені у вигляді "форматованих даних форми".

Якщо Ви оголосите тип параметра функції обробника маршруту як `bytes`, **FastAPI** прочитає файл за Вас, і Ви отримаєте його вміст у вигляді `bytes`.

Однак майте на увазі, що весь вміст буде збережено в пам'яті. Це працюватиме добре для малих файлів.

Але в деяких випадках Вам може знадобитися `UploadFile`.
