# 헤더 매개변수 모델 { #header-parameter-models }

관련 있는 **헤더 매개변수** 그룹이 있는 경우, **Pydantic 모델**을 생성하여 선언할 수 있습니다.

이를 통해 **여러 위치**에서 **모델을 재사용할** 수 있고 모든 매개변수에 대한 유효성 검사 및 메타데이터를 한 번에 선언할 수도 있습니다. 😎

/// note | 참고

이 기능은 FastAPI 버전 `0.115.0` 이후부터 지원됩니다. 🤓

///

## Pydantic 모델을 사용한 헤더 매개변수 { #header-parameters-with-a-pydantic-model }

**Pydantic 모델**에 필요한 **헤더 매개변수**를 선언한 다음, 해당 매개변수를 `Header`로 선언합니다:

# 標頭參數模型 { #header-parameter-models }

如果你有一組相關的標頭參數，可以建立一個 Pydantic 模型來宣告它們。

這能讓你在多處重複使用該模型，並一次性為所有參數宣告驗證與中繼資料。😎

/// note | 注意

自 FastAPI 版本 `0.115.0` 起支援。🤓

///

## 以 Pydantic 模型宣告標頭參數 { #header-parameters-with-a-pydantic-model }

在 Pydantic 模型中宣告你需要的標頭參數，然後將參數宣告為 `Header`：

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

FastAPI 會從請求的標頭為每個欄位擷取資料，並交給你已定義的 Pydantic 模型實例。

## Pydantic Model ile Header Parametreleri { #header-parameters-with-a-pydantic-model }

İhtiyacınız olan **header parametreleri**ni bir **Pydantic model** içinde tanımlayın, ardından parametreyi `Header` olarak belirtin:

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

**FastAPI**, request içindeki **headers** bölümünden **her alan** için veriyi **çıkarır** ve size tanımladığınız Pydantic model örneğini verir.

# Templating - `Jinja2Templates`

You can use the `Jinja2Templates` class to render Jinja templates.

Read more about it in the [FastAPI docs for Templates](https://fastapi.tiangolo.com/advanced/templates/).

You can import it directly from `fastapi.templating`:

```python
from fastapi.templating import Jinja2Templates
```
