## `HTTPSRedirectMiddleware` { #httpsredirectmiddleware }

强制所有传入请求必须是 `https` 或 `wss`。

{* ../../docs_src/advanced_middleware/tutorial001_py310.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

强制所有传入请求都必须正确设置 `Host` 请求头，以防 HTTP 主机头攻击。

{* ../../docs_src/advanced_middleware/tutorial002_py310.py hl[2,6:8] *}

支持以下参数：

maven.logger.levelInBrackets=true
maven.logger.log.Sisu=info
maven.logger.warnLevelString=WARNING

# MNG-6181: mvn -X also prints all debug logging from HttpClient

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。

{* ../../docs_src/header_param_models/tutorial003_an_py310.py hl[19] *}

/// warning | 警告

在将 `convert_underscores` 设为 `False` 之前，请注意某些 HTTP 代理和服务器不允许使用带下划线的 headers。
