`.add_task()` 的引數包括：

* 要在背景執行的任務函式（`write_notification`）。
* 依序傳給任務函式的位置引數（`email`）。
* 要傳給任務函式的關鍵字引數（`message="some notification"`）。

## 相依性注入 { #dependency-injection }

在相依性注入系統中也可使用 `BackgroundTasks`。你可以在多個層級宣告 `BackgroundTasks` 型別的參數：路徑操作函式、相依項（dependable）、次級相依項等。

**FastAPI** 會在各種情況下正確處理並重用同一個物件，將所有背景任務合併，並在之後於背景執行：

}

func initAllSubsystems(ctx context.Context) {
	// Initialize notification peer targets
	globalNotificationSys = NewNotificationSys(globalEndpoints)

	// Create new notification system
	if globalEventNotifier == nil {
		globalEventNotifier = NewEventNotifier(GlobalContext)
	}

	// Create new bucket metadata system.
