#### Documentation

Provides cross-cutting Gradle documentation and samples, along with the infrastructure to write, test, publish and host the documentation.

## Consequences

- Assign ownership of each architecture module to one team.
- Assign each source file to one architecture module.
- Align the source tree layout with this architecture.

强制所有传入请求必须是 `https` 或 `wss`。

任何传向 `http` 或 `ws` 的请求都会被重定向至安全方案。

{* ../../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：

* `allowed_hosts` - 允许的域名（主机名）列表。`*.example.com` 等通配符域名可以匹配子域名。若要允许任意主机名，可使用 `allowed_hosts=["*"]` 或省略此中间件。
