## Импорт `Header` { #import-header }

Сперва импортируйте `Header`:

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

## Объявление параметров `Header` { #declare-header-parameters }

Затем объявите параметры заголовка, используя ту же структуру, что и с `Path`, `Query` и `Cookie`.

@app.get("/cookie")
async def cookies_model_with_extra(data: Model = Cookie()):
    return data


def test_query_pass_extra_list():
    client = TestClient(app)
    resp = client.get(
        "/query",
        params={
            "param": "123",
            "param2": ["456", "789"],  # Pass a list of values as extra parameter
        },
    )
    assert resp.status_code == 200
    assert resp.json() == {
        "param": "123",

## `Header` 임포트

먼저 `Header`를 임포트합니다:

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

## `Header` 매개변수 선언

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

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

/// note | 기술 세부사항

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

Importieren Sie zuerst `Header`:

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

## `Header`-Parameter deklarieren { #declare-header-parameters }

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

定义 `Header` 参数的方式与定义 `Query`、`Path`、`Cookie` 参数相同。

## 导入 `Header`

首先，导入 `Header`：

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

## 声明 `Header` 参数

然后，使用和 `Path`、`Query`、`Cookie` 一样的结构定义 header 参数。

第一个值是默认值，还可以传递所有验证参数或注释参数：

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[9] *}

/// note | 技术细节

`Header` 是 `Path`、`Query`、`Cookie` 的**兄弟类**，都继承自共用的 `Param` 类。
