## `HTTPSRedirectMiddleware`

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.py hl[2,6] *}

## `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.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，或使用 `allowed_hosts=["*"]` 允许任意主机名，或省略中间件。

レスポンスモデルを指定するのと同じ方法で、レスポンスに使用されるHTTPステータスコードを以下の*path operations*のいずれかの`status_code`パラメータで宣言することもできます。

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

/// note | 備考

`status_code`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数*のものではありません。

///

`status_code`パラメータはHTTPステータスコードを含む数値を受け取ります。
