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：

```Python hl_lines="6"
{!../../docs_src/events/tutorial002.py!}
```

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。

/// tip | "Dica"

O "PATCH" é o último número, por exemplo, em `0.2.3`, a versão PATCH é `3`.

///

Logo, você deveria conseguir fixar a versão, como:

```txt
fastapi>=0.45.0,<0.46.0
```

Mudanças significativas e novos recursos são adicionados em versões "MINOR".
