이는 **FastAPI**의 제한 사항이 아니며 HTTP 프로토콜의 일부입니다.

因此，可以像在 Python 代码中一样使用 `user_agent` ，无需把首字母大写为 `User_Agent` 等形式。

如需禁用下划线自动转换为连字符，可以把 `Header` 的 `convert_underscores` 参数设置为 `False`：

{* ../../docs_src/header_params/tutorial002_an_py310.py hl[10] *}

/// warning | 警告

注意，使用 `convert_underscores = False` 要慎重，有些 HTTP 代理和服务器不支持使用带有下划线的请求头。

///

## 重复的请求头 { #duplicate-headers }

有时，可能需要接收重复的请求头。即同一个请求头有多个值。

类型声明中可以使用 `list` 定义多个请求头。

*path operation* で `operation_id` パラメータを利用することで、OpenAPIの `operationId` を設定できます。

與一般標頭參數相同，當參數名稱包含底線字元時，會自動轉換為連字號。

例如，若在程式碼中有標頭參數 `save_data`，實際期望的 HTTP 標頭為 `save-data`，在文件中也會如此顯示。

如果因某些原因需要停用這個自動轉換，你也可以在標頭參數的 Pydantic 模型上設定。

/// warning | 警告

在將 `convert_underscores` 設為 `False` 之前，請注意有些 HTTP 代理與伺服器不允許含有底線的標頭。
