# ヘッダーのパラメータ { #header-parameters }

ヘッダーのパラメータは、`Query`や`Path`、`Cookie`のパラメータを定義するのと同じように定義できます。

## `Header`をインポート { #import-header }

まず、`Header`をインポートします:

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

## `Header`のパラメータの宣言 { #declare-header-parameters }

次に、`Path`や`Query`、`Cookie`と同じ構造を用いてヘッダーのパラメータを宣言します。

デフォルト値に加えて、追加の検証パラメータや注釈パラメータをすべて定義できます:

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

# Header 参数模型 { #header-parameter-models }

如果您有一组相关的 **header 参数**，您可以创建一个 **Pydantic 模型**来声明它们。

这将允许您在**多个地方**能够**重用模型**，并且可以一次性声明所有参数的验证和元数据。😎

/// note | 注意

自 FastAPI 版本 `0.115.0` 起支持此功能。🤓

## 使用 Pydantic 模型的 Header 参数 { #header-parameters-with-a-pydantic-model }

在 **Pydantic 模型**中声明所需的 **header 参数**，然后将参数声明为 `Header` :

{* ../../docs_src/header_param_models/tutorial001_an_py310.py hl[9:14,18] *}
