Pydantic 모델 대신 `dict`로 직접 작업한다면 이런 종류의 편집기 지원을 받을 수 없습니다.

하지만 그 부분에 대해서도 걱정할 필요는 없습니다. 들어오는 dict는 자동으로 변환되고, 출력도 자동으로 JSON으로 변환됩니다.

## 임의의 `dict` 본문 { #bodies-of-arbitrary-dicts }

또한 키는 어떤 타입이고 값은 다른 타입인 `dict`로 본문을 선언할 수 있습니다.

이렇게 하면 (Pydantic 모델을 사용하는 경우처럼) 유효한 필드/어트리뷰트 이름이 무엇인지 미리 알 필요가 없습니다.

아직 모르는 키를 받으려는 경우에 유용합니다.

在更深入了解 **相依性注入（Dependency Injection）** 系統之前，我們先把前一個範例升級一下。

## 前一個範例中的 `dict` { #a-dict-from-the-previous-example }

在前一個範例中，我們從相依項（"dependable"）回傳了一個 `dict`：

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

但接著我們在路徑操作函式（*path operation function*）的參數 `commons` 中取得的是一個 `dict`。

而我們知道，編輯器對 `dict` 無法提供太多輔助（例如自動完成），因為它無法預先知道其中的鍵與值的型別。

我們可以做得更好...

## 什麼算是相依性 { #what-makes-a-dependency }

You couldn't get this kind of editor support if you were working directly with `dict` instead of Pydantic models.

But you don't have to worry about them either, incoming dicts are converted automatically and your output is converted automatically to JSON too.

## Bodies of arbitrary `dict`s { #bodies-of-arbitrary-dicts }

You can also declare a body as a `dict` with keys of some type and values of some other type.
