And as the `Response` can be used frequently to set headers and cookies, **FastAPI** also provides it at `fastapi.Response`.

# Header-параметри

Ви можете визначати параметри заголовків, так само як визначаєте `Query`, `Path` і `Cookie` параметри.

## Імпорт `Header`

Спочатку імпортуйте `Header`:

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

## Оголошення параметрів `Header`

Потім оголосіть параметри заголовків, використовуючи ту ж структуру, що й для `Path`, `Query` та `Cookie`.

<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>
<la:form action="/search" method="get" styleId="searchForm"
	role="search">
	${fe:facetForm()}${fe:geoForm()}
	<header>
		<nav class="navbar navbar-expand-md navbar-dark fixed-top bg-dark d-print-none">
			<div id="content" class="container">
				<la:link styleClass="navbar-brand d-inline-flex" href="/">
					<img src="${fe:url('/images/logo-head.png')}"

## `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] *}

## Пользовательские HTTP-заголовки { #custom-headers }

Помните, что собственные проприетарные заголовки можно добавлять, <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">используя префикс `X-`</a>.
