/// note | Teknik Detaylar

Formlardan gelen veri, dosya içermiyorsa normalde "media type" olarak `application/x-www-form-urlencoded` ile encode edilir.

Ancak form dosya içeriyorsa `multipart/form-data` olarak encode edilir. `File` kullanırsanız, **FastAPI** dosyaları body’nin doğru kısmından alması gerektiğini bilir.

Якщо вам потрібне щось просте для інтеграції з FastAPI, але більш надійне, з підтримкою Redis, PostgreSQL чи інших, перегляньте [encode/broadcaster](https://github.com/encode/broadcaster).

Bu aynı zamanda `StreamingResponse` ile veriyi tam olarak ihtiyaç duyduğunuz biçimde üretme ve encode etme konusunda hem bir özgürlük hem de bir sorumluluk verdiği anlamına gelir; tip annotasyonlarından bağımsızdır. 🤓
