따라서 모든 작업을 의도한대로 실행하기 위해, 허용되는 출처를 명시적으로 지정하는 것이 좋습니다.

## `CORSMiddleware` 사용

`CORSMiddleware` 을 사용하여 **FastAPI** 응용 프로그램의 교차 출처 리소스 공유 환경을 설정할 수 있습니다.

* `CORSMiddleware` 임포트.
* 허용되는 출처(문자열 형식)의 리스트 생성.
* FastAPI 응용 프로그램에 "미들웨어(middleware)"로 추가.

백엔드에서 다음의 사항을 허용할지에 대해 설정할 수도 있습니다:

* 자격증명 (인증 헤더, 쿠키 등).
* 특정한 HTTP 메소드(`POST`, `PUT`) 또는 와일드카드 `"*"` 를 사용한 모든 HTTP 메소드.

# Corpo - Modelos aninhados

Com o **FastAPI**, você pode definir, validar, documentar e usar modelos profundamente aninhados de forma arbitrária (graças ao Pydantic).

## Campos do tipo Lista

Você pode definir um atributo como um subtipo. Por exemplo, uma `list` do Python:

```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial001.py!}
```

def test_token():

We are doing it here to demonstrate how **FastAPI** handles scopes declared at different levels.

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,140,171] *}

/// info | "Technical Details"

`Security` is actually a subclass of `Depends`, and it has just one extra parameter that we'll see later.

{!> ../../docs_src/response_model/tutorial003.py!}

因此，**FastAPI** 将会负责过滤掉未在输出模型中声明的所有数据（使用 Pydantic）。

## 在文档中查看

当你查看自动化文档时，你可以检查输入模型和输出模型是否都具有自己的 JSON Schema：

并且两种模型都将在交互式 API 文档中使用：
