   * reason that this is warmupPeriod/2 is to maintain the behavior of the original implementation

   * <p>It remains to calculate thresholdsPermits and maxPermits.

Si intentas interactuar con cualquiera de las dos interfaces de usuario, funcionarán correctamente, porque el navegador podrá comunicarse con cada aplicación o sub-aplicación específica.

### Detalles Técnicos: `root_path` { #technical-details-root-path }

Cuando montas una sub-aplicación como se describe arriba, FastAPI se encargará de comunicar el path de montaje para la sub-aplicación usando un mecanismo de la especificación ASGI llamado `root_path`.

### Detalhes Técnicos: `root_path` { #technical-details-root-path }

Quando você monta uma sub-aplicação como descrito acima, o FastAPI se encarrega de comunicar o path de montagem para a sub-aplicação usando um mecanismo da especificação ASGI chamado `root_path`.

到目前為止，你都是用對應的型別來宣告你需要的請求各部分。

例如從以下來源取得資料：

- 路徑中的參數。
- 標頭。
- Cookies。
- 等等。

這麼做時，FastAPI 會自動驗證並轉換這些資料，還會為你的 API 產生文件。

但有些情況你可能需要直接存取 `Request` 物件。

## 關於 `Request` 物件的細節 { #details-about-the-request-object }

由於 FastAPI 底層其實是 Starlette，再加上一層工具，因此在需要時你可以直接使用 Starlette 的 [`Request`](https://www.starlette.dev/requests/) 物件。

之後若你造訪 `/openapi.json`、`/docs` 或 `/redoc`，會看到如下的 `404 Not Found` 錯誤：

```JSON

    "detail": "Not Found"
