**FastAPI**는 경로 매개변수와 일치하는 함수 매개변수가 **경로에서 가져와야 한다**는 것을 인지하며, Pydantic 모델로 선언된 그 함수 매개변수는 **요청 본문에서 가져와야 한다**는 것을 인지할 것입니다.

{* ../../docs_src/body/tutorial003_py310.py hl[15:16] *}


## 요청 본문 + 경로 + 쿼리 매개변수 { #request-body-path-query-parameters }

**본문**, **경로** 그리고 **쿼리** 매개변수 모두 동시에 선언할 수도 있습니다.

**FastAPI**는 각각을 인지하고 데이터를 올바른 위치에 가져올 것입니다.

{* ../../docs_src/body/tutorial004_py310.py hl[16] *}

함수 매개변수는 다음을 따라서 인지하게 됩니다:

## Benefícios { #benefits }

Ao usar os clientes gerados automaticamente, você terá **preenchimento automático** para:

* Métodos.
* Corpos de requisições, parâmetros de query, etc.
* Corpos de respostas.

Você também terá **erros em linha** para tudo.

Es kann jedoch Fälle geben, in denen Sie Parameter für eine Abhängigkeit festlegen möchten, ohne viele verschiedene Funktionen oder Klassen zu deklarieren.

Stellen wir uns vor, wir möchten eine Abhängigkeit haben, die prüft, ob ein Query-Parameter `q` einen vordefinierten Inhalt hat.

Aber wir wollen diesen vordefinierten Inhalt per Parameter festlegen können.

## Eine „aufrufbare“ Instanz { #a-callable-instance }

* HTTP Basic.
* **OAuth2** (also with **JWT tokens**). Check the tutorial on [OAuth2 with JWT](tutorial/security/oauth2-jwt.md).
* API keys in:
    * Headers.
    * Query parameters.
    * Cookies, etc.

Plus all the security features from Starlette (including **session cookies**).
