# Header 参数 { #header-parameters }

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

## 导入 `Header` { #import-header }

首先，导入 `Header`：

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

## 声明 `Header` 参数 { #declare-header-parameters }

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] *}

# 경로 매개변수와 숫자 검증 { #path-parameters-and-numeric-validations }

`Query`를 사용하여 쿼리 매개변수에 더 많은 검증과 메타데이터를 선언하는 방법과 동일하게 `Path`를 사용하여 경로 매개변수에 검증과 메타데이터를 같은 타입으로 선언할 수 있습니다.

## `Path` 임포트 { #import-path }

먼저 `fastapi`에서 `Path`를 임포트하고, `Annotated`도 임포트합니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info | 정보

FastAPI는 0.95.0 버전에서 `Annotated` 지원을 추가했고(그리고 이를 권장하기 시작했습니다).

# Cookie Parameter Models { #cookie-parameter-models }

If you have a group of **cookies** that are related, you can create a **Pydantic model** to declare them. 🍪

This would allow you to **re-use the model** in **multiple places** and also to declare validations and metadata for all the parameters at once. 😎

This is supported since FastAPI version `0.115.0`. 🤓
