任何指向 `http` 或 `ws` 的請求都會被重新導向至對應的安全協定。

強制所有傳入請求正確設定 `Host` 標頭，以防範 HTTP Host Header 攻擊。

支援以下參數：

- `allowed_hosts` - 允許作為主機名稱的網域名稱清單。支援萬用字元網域（例如 `*.example.com`）以比對子網域。若要允許任意主機名稱，可使用 `allowed_hosts=["*"]`，或乾脆不要加上此中介軟體。

而且它們都會使用同一個 WebSocket 連線。

## 使用 `Depends` 與其他功能 { #using-depends-and-others }

在 WebSocket 端點中，你可以從 `fastapi` 匯入並使用：

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

它們的運作方式與其他 FastAPI 端點/*路徑操作* 相同：
