일부 타입의 키와 다른 타입의 값을 사용하여 `dict`로 본문을 선언할 수 있습니다.

(Pydantic을 사용한 경우처럼) 유효한 필드/어트리뷰트 이름이 무엇인지 알 필요가 없습니다.

아직 모르는 키를 받으려는 경우 유용합니다.

---

다른 유용한 경우는 다른 타입의 키를 가질 때입니다. 예. `int`.

여기서 그 경우를 볼 것입니다.

이 경우, `float` 값을 가진 `int` 키가 있는 모든 `dict`를 받아들입니다:

{* ../../docs_src/body_nested_models/tutorial009.py hl[15] *}

/// tip | 팁

JSON은 오직 `str`형 키만 지원한다는 것을 염두에 두세요.

하지만 Pydantic은 자동 데이터 변환이 있습니다.

But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
