**FastAPI** 支持多个事件处理器函数。

只有所有 `startup` 事件处理器运行完毕，**FastAPI** 应用才开始接收请求。

### `shutdown` 事件

使用 `shutdown` 事件声明 `app` 关闭时运行的函数：

{* ../../docs_src/events/tutorial002.py hl[6] *}

此处，`shutdown` 事件处理器函数在 `log.txt` 中写入一行文本 `Application shutdown`。

/// info | 说明

`open()` 函数中，`mode="a"` 指的是**追加**。因此这行文本会添加在文件已有内容之后，不会覆盖之前的内容。

///

/// tip | 提示

注意，本例使用 Python `open()` 标准函数与文件交互。

	if err != nil {
		return err
	}

### Contêiner Único { #single-container }

Se você tiver uma configuração simples, com um **único contêiner** que então inicia vários **processos workers** (ou também apenas um processo), então poderia executar esses passos anteriores no mesmo contêiner, logo antes de iniciar o processo com o aplicativo.
