def get_client(request: pytest.FixtureRequest):

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.

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

Primeiro, importe `Path` de `fastapi`, e importe `Annotated`:

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

/// info | Informação

O FastAPI adicionou suporte a `Annotated` (e passou a recomendá-lo) na versão 0.95.0.

Se você tiver uma versão mais antiga, verá erros ao tentar usar `Annotated`.

### Die Abhängigkeit im <abbr title="Das Abhängige, der Verwender der Abhängigkeit">„Dependant“</abbr> deklarieren { #declare-the-dependency-in-the-dependant }

So wie auch `Body`, `Query`, usw., verwenden Sie `Depends` mit den Parametern Ihrer *Pfadoperation-Funktion*:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

## Імпорт Path

Спочатку імпортуйте `Path` з `fastapi` і імпортуйте `Annotated`:

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

/// info | Інформація

FastAPI додав підтримку `Annotated`  (і почав рекомендувати його використання) у версії 0.95.0.

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### Declarando a dependência, no "dependente" { #declare-the-dependency-in-the-dependant }

Da mesma forma que você utiliza `Body`, `Query`, etc. Como parâmetros de sua *função de operação de rota*, utilize `Depends` com um novo parâmetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}
