And mentioned me to him:
        She gave me a good character,
          But said I could not swim.

        He sent them word I had not gone
          (We know it to be true):
        If she should push the matter on,
          What would become of you?

        I gave her one, they gave him two,
          You gave us three or more;
        They all returned from him to you,

## 禁用下划线转换 { #disable-convert-underscores }

与常规的 header 参数相同，当参数名中包含下划线时，会**自动转换为连字符**。

例如，如果你的代码中有一个名为 `save_data` 的 header 参数，那么预期的 HTTP 头将是 `save-data`，并且在文档中也会以这种形式显示。

如果由于某些原因你需要禁用这种自动转换，你也可以在用于 header 参数的 Pydantic 模型中进行设置。

def homepage():
    text = '<a href="%s">Authenticate with keycloak</a>'
    return text % make_authorization_url()


def make_authorization_url():
    # Generate a random string for the state parameter
    # Save it for use later to prevent xsrf attacks

    state = str(uuid4())
    params = {"client_id": client_id,
              "response_type": "code",
              "state": state,
              "redirect_uri": callback_uri,

Как и в случае с обычными заголовками, если у вас в именах параметров имеются символы подчеркивания, они **автоматически преобразовываются в дефис**.

Например, если в коде есть header-параметр `save_data`, то ожидаемый HTTP-заголовок будет `save-data` и именно так он будет отображаться в документации.

Если по каким-то причинам вам нужно отключить данное автоматическое преобразование, это можно сделать и для Pydantic-моделей для header-параметров.
