**Alerta de Spoiler**: o tutorial - guia do usuário inclui:

* Declaração de **parâmetetros** de diferentes lugares como: **cabeçalhos**, **cookies**, **campos de formulários** e **arquivos**.
* Como configurar **Limitações de Validação** como `maximum_length` ou `regex`.

    else:

            field_info_in == params.ParamTypes.cookie
        ), f"non-body parameters must be in path, query, header or cookie: {field.name}"

    handling in WebSockets is significantly improved.
 *  Fix: Don't use SPDY/3 style header concatenation for HTTP/2 request headers.
    This could have corrupted requests where multiple headers had the same name,
    as in cookies.
 *  Fix: Reject bad characters in the URL hostname. Previously characters like
    `\0` would cause a late crash when building the request.
 *  Fix: Allow interceptors to change the request method.

#### Forbid Extra Query (Cookie, Header) Parameters

Use Pydantic models to restrict extra values for `Query` parameters (also applies to `Header` and `Cookie` parameters).

   * cookies can be 4KiB, and should be possible to send.

クッキーのパラメータは、`Query`や`Path`のパラメータを定義するのと同じ方法で定義できます。

## `Cookie`をインポート

まず、`Cookie`をインポートします:

```Python hl_lines="3"
{!../../docs_src/cookie_params/tutorial001.py!}
```

## `Cookie`のパラメータを宣言

次に、`Path`や`Query`と同じ構造を使ってクッキーのパラメータを宣言します。

最初の値がデフォルト値で、追加の検証パラメータや注釈パラメータをすべて渡すことができます:

```Python hl_lines="9"
{!../../docs_src/cookie_params/tutorial001.py!}
```

# Çerez (Cookie) Parametreleri

`Query` (Sorgu) ve `Path` (Yol) parametrelerini tanımladığınız şekilde çerez parametreleri tanımlayabilirsiniz.

## Import `Cookie`

Öncelikle, `Cookie`'yi projenize dahil edin:
