Para lograr eso, importa `JSONResponse`, y devuelve tu contenido allí directamente, configurando el `status_code` que deseas:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

/// warning | Advertencia

Cuando devuelves un `Response` directamente, como en el ejemplo anterior, se devuelve directamente.

No se serializará con un modelo, etc.

解码并校验接收到的令牌，然后，返回当前用户。

如果令牌无效，则直接返回 HTTP 错误。

{* ../../docs_src/security/tutorial004_an_py310.py hl[4,7,13:15,29:31,79:87] *}

## 更新 `/token` *路径操作*

用令牌过期时间创建 `timedelta` 对象。

创建并返回真正的 JWT 访问令牌。

{* ../../docs_src/security/tutorial004_an_py310.py hl[118:133] *}

### JWT `sub` 的技术细节

JWT 规范还包括 `sub` 键，值是令牌的主题。

该键是可选的，但要把用户标识放在这个键里，所以本例使用了该键。

## Importer Path

Tout d'abord, importez `Path` de `fastapi`, et importez `Annotated` :

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info

FastAPI a ajouté le support pour `Annotated` (et a commencé à le recommander) dans la version 0.95.0.
