**FastAPI** 使用依赖项在 OpenAPI 概图（及 API 文档）中定义**安全方案**。

/// info | 技术细节

**FastAPI** 使用（在依赖项中声明的）类 `OAuth2PasswordBearer` 在 OpenAPI 中定义安全方案，这是因为它继承自 `fastapi.security.oauth2.OAuth2`，而该类又是继承自`fastapi.security.base.SecurityBase`。

所有与 OpenAPI（及 API 文档）集成的安全工具都继承自 `SecurityBase`， 这就是为什么 **FastAPI** 能把它们集成至 OpenAPI 的原因。

///

## 实现的操作

FastAPI 校验请求中的 `Authorization` 请求头，核对请求头的值是不是由 `Bearer ` ＋ 令牌组成， 并返回令牌字符串（`str`）。

코드 중복은 버그, 보안 문제, 코드 비동기화 문제(한 곳은 업데이트되었지만 다른 곳은 업데이트되지 않는 문제) 등의 가능성을 증가시킵니다.

그리고 이 모델들은 많은 데이터를 공유하면서 속성 이름과 타입을 중복하고 있습니다.

더 나은 방법이 있습니다.

`UserBase` 모델을 선언하여 다른 모델들의 기본(base)으로 사용할 수 있습니다. 그런 다음 이 모델을 상속받아 속성과 타입 선언(유형 선언, 검증 등)을 상속하는 서브클래스를 만들 수 있습니다.

모든 데이터 변환, 검증, 문서화 등은 정상적으로 작동할 것입니다.

이렇게 하면 각 모델 간의 차이점만 선언할 수 있습니다(평문 `password`가 있는 경우, `hashed_password`만 있는 경우, 혹은 비밀번호가 없는 경우):
