Pero aún quieres poder filtrar y convertir los datos que retornas con un `response_model`.

Para esos casos, puedes usar un parámetro `Response`.

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de la operación de path* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de respuesta *temporal*.

# 响应 - 更改状态码

你可能之前已经了解到，你可以设置默认的[响应状态码](../tutorial/response-status-code.md){.internal-link target=_blank}。

但在某些情况下，你需要返回一个不同于默认值的状态码。

## 使用场景

例如，假设你想默认返回一个HTTP状态码为“OK”`200`。

但如果数据不存在，你想创建它，并返回一个HTTP状态码为“CREATED”`201`。

但你仍然希望能够使用`response_model`过滤和转换你返回的数据。

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。
