Esto es compatible desde la versión `0.115.0` de FastAPI. 🤓

## "Form Alanları" Hakkında

HTML formlarının (`<form></form>`) verileri sunucuya gönderirken JSON'dan farklı özel bir kodlama kullanır.

**FastAPI** bu verilerin JSON yerine doğru şekilde okunmasını sağlayacaktır.

/// note | Teknik Detaylar

Form verileri normalde `application/x-www-form-urlencoded` medya tipiyle kodlanır.
