## Monter une sous-application { #mounting-a-sub-application }

Si vous avez besoin de monter une sous‑application (comme décrit dans [Sous‑applications - montages](sub-applications.md)) tout en utilisant un proxy avec `root_path`, vous pouvez le faire normalement, comme vous vous y attendez.

     * If that matcher returns {@code false}, then the directory will definitively not contain
     * the paths selected by the matcher given in argument to this method.
     * In such case, the whole directory and all its sub-directories can be skipped.
     * In case of doubt, or if the matcher given in argument is not recognized by this method,
     * then the matcher returned by this method will return {@code true}.

Usar `BackgroundTasks` también funciona con el sistema de inyección de dependencias, puedes declarar un parámetro de tipo `BackgroundTasks` en varios niveles: en una *path operation function*, en una dependencia (dependable), en una sub-dependencia, etc.

**FastAPI** sabe qué hacer en cada caso y cómo reutilizar el mismo objeto, de modo que todas las tareas en segundo plano se combinan y ejecutan en segundo plano después:

因此，你可以在相依內用 `except SomeException` 來攔截特定例外。

同樣地，你可以使用 `finally` 來確保無論是否有例外都會執行結束步驟。

## 含 `yield` 的子相依 { #sub-dependencies-with-yield }

你可以擁有任何大小與形狀的子相依與相依樹，而它們都可以（或不）使用 `yield`。

**FastAPI** 會確保每個使用 `yield` 的相依，其「結束程式碼」會以正確的順序執行。

例如，`dependency_c` 可以相依於 `dependency_b`，而 `dependency_b` 相依於 `dependency_a`：

> NOTE: MinIO environmental variables still take precedence over the `config.yaml` file, however `config.yaml` is preferred over MinIO internal config KV settings via `mc admin config set alias/ <sub-system>`.

### TODO

In subsequent releases we are planning to extend this to provide things like

- Reload() of MinIO server arguments without fully restarting the process.
