## Importe `Header` { #import-header }

Primeiro importe `Header`:

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

## Declare parâmetros de `Header` { #declare-header-parameters }

Então declare os paramêtros de cabeçalho usando a mesma estrutura que em `Path`, `Query` e `Cookie`.

 * list is a single empty string: `[""]`.
 *
 * ### Query
 *
 * The query is optional: it can be null, empty, or non-empty. For many HTTP URLs the query string
 * is subdivided into a collection of name-value parameters. This class offers methods to set the
 * query as the single string, or as individual name-value parameters. With name-value parameters

from typing import Union

from fastapi import FastAPI, Path, Query

app = FastAPI()


@app.get("/items/{item_id}")
async def read_items(
    item_id: int = Path(title="The ID of the item to get"),
    q: Union[str, None] = Query(default=None, alias="item-query"),
):
    results = {"item_id": item_id}
    if q:
        results.update({"q": q})

                cb.query().setDescription_Wildcard(dataConfigPager.description);
            } else if (dataConfigPager.description.endsWith("*")) {
                cb.query().setDescription_Prefix(dataConfigPager.description.replaceAll("\\*$", StringUtil.EMPTY));
            } else {
                cb.query().setDescription_MatchPhrase(dataConfigPager.description);
            }
        }

# クッキーのパラメータ

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:

{* ../../docs_src/cookie_params/tutorial001.py hl[3] *}

## `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:

{* ../../docs_src/cookie_params/tutorial001.py hl[9] *}

/// note | 技術詳細

`Cookie`は`Path`と`Query`の「姉妹」クラスです。また、同じ共通の`Param`クラスを継承しています。
