你可以定义在返回响应后运行的后台任务。

这对需要在请求之后执行的操作很有用，但客户端不必在接收响应之前等待操作完成。

包括这些例子：

* 执行操作后发送的电子邮件通知：
    * 由于连接到电子邮件服务器并发送电子邮件往往很“慢”（几秒钟），您可以立即返回响应并在后台发送电子邮件通知。
* 处理数据：
    * 例如，假设您收到的文件必须经过一个缓慢的过程，您可以返回一个"Accepted"(HTTP 202)响应并在后台处理它。

## 使用 `BackgroundTasks` { #using-backgroundtasks }

首先导入 `BackgroundTasks` 并在 *路径操作函数* 中使用类型声明 `BackgroundTasks` 定义一个参数：

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

**FastAPI** a sa propre `HTTPException`.

Et la classe d'erreur `HTTPException` de **FastAPI** hérite de la classe d'erreur `HTTPException` de Starlette.

La seule différence est que la `HTTPException` de **FastAPI** accepte toute donnée sérialisable en JSON pour le champ `detail`, tandis que la `HTTPException` de Starlette n'accepte que des chaînes.

Ainsi, vous pouvez continuer à lever la `HTTPException` de **FastAPI** normalement dans votre code.

            return builder.execute();
        }).getHits().getTotalHits();
        return totalHits != null ? (int) totalHits.value() : 0;
