/// check | 启发 **FastAPI**：

寻找获得卓越性能的方法。

与 Hug（Hug 基于 Falcon）一起，启发 **FastAPI** 在函数中声明一个 `response` 参数。尽管在 FastAPI 中它是可选的，主要用于设置 headers、cookies 和可选的状态码。

我在构建 **FastAPI** 的早期阶段发现了 Molten。它有不少相似的想法：

* 基于 Python 类型提示。
* 从这些类型获得校验与文档。
* 依赖注入系统。

* <dfn title="also known as: serialization, parsing, marshalling">Conversion</dfn> of input data: coming from the network to Python data and types. Reading from:

    * Files.

of cookies that net/http will accept when parsing HTTP headers. If the number of
cookie in a header exceeds the number set in `httpcookiemaxnum`, cookie parsing
will fail early. The default value is `httpcookiemaxnum=3000`. Setting
`httpcookiemaxnum=0` will allow the cookie parsing to accept an indefinite
number of cookies. To avoid denial of service attacks, this setting and default

## Pydantic-модель для cookies { #cookies-with-a-pydantic-model }

Объявите параметры **cookie**, которые вам нужны, в **Pydantic-модели**, а затем объявите параметр как `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

**FastAPI** **извлечёт** данные для **каждого поля** из **cookies**, полученных в запросе, и выдаст вам объявленную Pydantic-модель.

///

## Cookies com Modelos Pydantic { #cookies-with-a-pydantic-model }

Declare os parâmetros de **cookie** de que você precisa em um **modelo Pydantic**, e depois declare o parâmetro como `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

Diese gleiche Technik gilt für `Query`, `Cookie` und `Header`. 😎

///

## Cookies mit einem Pydantic-Modell { #cookies-with-a-pydantic-model }

Deklarieren Sie die **Cookie**-Parameter, die Sie benötigen, in einem **Pydantic-Modell**, und deklarieren Sie dann den Parameter als `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

///

## Cookies con un Modelo de Pydantic { #cookies-with-a-pydantic-model }

Declara los parámetros de **cookie** que necesites en un **modelo de Pydantic**, y luego declara el parámetro como `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

# Paramètres de cookie { #cookie-parameters }

Vous pouvez définir des paramètres de cookie de la même manière que vous définissez les paramètres `Query` et `Path`.

## Importer `Cookie` { #import-cookie }

Commencez par importer `Cookie` :
