You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/cookie_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra cookies**, they will receive an **error** response.

## 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.

      val cookieA = parseCookie(0, url, stringA!!)
      for (stringB in cookieStrings) {
        val cookieB = parseCookie(0, url, stringB!!)
        if (stringA == stringB) {
          assertThat(cookieB.hashCode()).isEqualTo(cookieA.hashCode())
          assertThat(cookieB).isEqualTo(cookieA)
        } else {
          assertThat(cookieB.hashCode()).isNotEqualTo(cookieA.hashCode().toLong())

# Cookies de Response { #response-cookies }

## Usar un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function*.

Y luego puedes establecer cookies en ese objeto de response *temporal*.

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

# Cookie-Parameter { #cookie-parameters }

Sie können Cookie-Parameter auf die gleiche Weise definieren wie `Query`- und `Path`-Parameter.

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

Importieren Sie zuerst `Cookie`:

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

## `Cookie`-Parameter deklarieren { #declare-cookie-parameters }

Deklarieren Sie dann die Cookie-Parameter mit derselben Struktur wie bei `Path` und `Query`.

# Parámetros de Cookie { #cookie-parameters }

Puedes definir parámetros de Cookie de la misma manera que defines los parámetros `Query` y `Path`.

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

Primero importa `Cookie`:

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

## Declarar parámetros de `Cookie` { #declare-cookie-parameters }

Luego declara los parámetros de cookie usando la misma estructura que con `Path` y `Query`.

# Cookie Parameters { #cookie-parameters }

You can define Cookie parameters the same way you define `Query` and `Path` parameters.

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

First import `Cookie`:

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

## Declare `Cookie` parameters { #declare-cookie-parameters }

Then declare the cookie parameters using the same structure as with `Path` and `Query`.

# Response Cookies { #response-cookies }

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

You can declare a parameter of type `Response` in your *path operation function*.

And then you can set cookies in that *temporal* response object.

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

`Response` parametresini dependency'lerde de tanımlayıp, onların içinde cookie (ve header) set edebilirsiniz.

## Doğrudan bir `Response` döndürün { #return-a-response-directly }

Kodunuzda doğrudan bir `Response` döndürürken de cookie oluşturabilirsiniz.

Bunu yapmak için, [Doğrudan Response Döndürme](response-directly.md) bölümünde anlatıldığı gibi bir response oluşturabilirsiniz.

# 回應 Cookie { #response-cookies }

## 使用 `Response` 參數 { #use-a-response-parameter }

你可以在路徑操作函式（path operation function）中宣告一個型別為 `Response` 的參數。

接著你可以在那個「暫時」的 `Response` 物件上設定 Cookie。

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

之後如常回傳你需要的任何物件（例如 `dict`、資料庫模型等）。

如果你宣告了 `response_model`，它仍會用來過濾並轉換你回傳的物件。

FastAPI 會使用那個暫時的 `Response` 取出 Cookie（以及標頭與狀態碼），並將它們放入最終回應；最終回應包含你回傳的值，且會套用任何 `response_model` 的過濾。
