O **FastAPI** criará o objeto do tipo `BackgroundTasks` para você e o passará como esse parâmetro.

## Crie uma função de tarefa { #create-a-task-function }

Crie uma função para ser executada como a tarefa em segundo plano.

É apenas uma função padrão que pode receber parâmetros.

含有 `yield` 的相依隨著時間演進，以涵蓋不同的使用情境並修正一些問題。以下是變更摘要。

### 含有 `yield` 與 `scope` 的相依 { #dependencies-with-yield-and-scope }

在 0.121.0 版中，FastAPI 為含有 `yield` 的相依加入了 `Depends(scope="function")` 的支援。

使用 `Depends(scope="function")` 時，`yield` 之後的結束程式碼會在「路徑操作函式」執行完畢後立刻執行，在回應發送回客戶端之前。

而當使用 `Depends(scope="request")`（預設值）時，`yield` 之後的結束程式碼會在回應送出之後才執行。
