# 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。

当时 JSON Schema 没有 `examples`，所以 OpenAPI 在它修改过的版本中添加了自己的 `example` 字段。

OpenAPI 还在规范的其他部分添加了 `example` 和 `examples` 字段：

- [`Parameter Object`（规范中）](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object)，被 FastAPI 的以下内容使用：
    - `Path()`
    - `Query()`
    - `Header()`
    - `Cookie()`
