# Cookies de Resposta { #response-cookies }

## Use um parâmetro `Response` { #use-a-response-parameter }

Você pode declarar um parâmetro do tipo `Response` na sua *função de operação de rota*.

E então você pode definir cookies nesse objeto de resposta *temporário*.

# Cabeçalhos de resposta { #response-headers }

## Use um parâmetro `Response` { #use-a-response-parameter }

Você pode declarar um parâmetro do tipo `Response` na sua *função de operação de rota* (assim como você pode fazer para cookies).

Então você pode definir os cabeçalhos nesse objeto de resposta *temporário*.

{* ../../docs_src/response_headers/tutorial002_py310.py hl[1, 7:8] *}

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)。

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 { #use-case }

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 { #use-a-response-parameter }

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`。
