**FastAPI** extrait les données de **chaque champ** depuis les **en-têtes** de la requête et vous fournit le modèle Pydantic que vous avez défini.

## Consulter la documentation { #check-the-docs }

Vous pouvez voir les en-têtes requis dans l'interface de la documentation à `/docs` :

**FastAPI**는 요청의 **쿼리 매개변수**에서 **각 필드**의 데이터를 **추출**해 정의한 Pydantic 모델을 제공합니다.

## 문서 확인하기 { #check-the-docs }

Request body'lerinin de Pydantic modelleri ile bildirildiğini hatırlıyor olabilirsiniz.

Burada `Depends` kullandığınız için **FastAPI** karışıklık yaşamaz.

/// check | Ek bilgi

Bu dependency sisteminin tasarımı, hepsi `User` modeli döndüren farklı dependency'lere (farklı "dependable"lara) sahip olmamıza izin verir.

Bu tipte veri döndürebilen yalnızca tek bir dependency ile sınırlı değiliz.
