## Импорт `Path` { #import-path }

Сначала импортируйте `Path` из `fastapi`, а также импортируйте `Annotated`:

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

/// info | Информация

Поддержка `Annotated` была добавлена в FastAPI начиная с версии 0.95.0 (и с этой версии рекомендуется использовать этот подход).

## Importar Path { #import-path }

Primero, importa `Path` de `fastapi`, e importa `Annotated`:

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

/// info | Información

FastAPI agregó soporte para `Annotated` (y comenzó a recomendar su uso) en la versión 0.95.0.

Si tienes una versión anterior, obtendrás errores al intentar usar `Annotated`.

## `Path` importieren { #import-path }

Importieren Sie zuerst `Path` von `fastapi`, und importieren Sie `Annotated`:

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

/// info | Info

FastAPI hat in Version 0.95.0 Unterstützung für `Annotated` hinzugefügt und es zur Verwendung empfohlen.

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。
