You can use Pydantic's model configuration to `forbid` any `extra` fields:

If a client tries to send some **extra cookies**, they will receive an **error** response.

//     specify a different capacity; it must be no smaller than the
//     length. For example, make([]int, 0, 10) allocates an underlying array
//     of size 10 and returns a slice of length 0 and capacity 10 that is
//     backed by this underlying array.
//   - Map: An empty map is allocated with enough space to hold the
//     specified number of elements. The size may be omitted, in which case

/// warning | Achtung

Bevor Sie `convert_underscores` auf `False` setzen, bedenken Sie, dass manche HTTP-Proxys und Server die Verwendung von Headern mit Unterstrichen nicht erlauben.

///

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

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。
