## 嵌套模型 { #nested-models }

Pydantic 模型的每个属性都具有类型。

但是这个类型本身可以是另一个 Pydantic 模型。

因此，你可以声明拥有特定属性名称、类型和校验的深度嵌套的 JSON 对象。

上述这些都可以任意的嵌套。

### 定义子模型 { #define-a-submodel }

例如，我们可以定义一个 `Image` 模型：

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### 将子模型用作类型 { #use-the-submodel-as-a-type }

然后我们可以将其用作一个属性的类型：

Crea una variable `ALGORITHM` con el algoritmo usado para firmar el token JWT y configúralo a `"HS256"`.

Crea una variable para la expiración del token.

Define un Modelo de Pydantic que se usará en el endpoint de token para el response.

Crea una función de utilidad para generar un nuevo token de acceso.
