É uma grande ferramenta e eu também a utilizei bastante, antes de ter o **FastAPI**.

... rend le paramètre optionnel, et est donc équivalent à :

```Python
q: Union[str, None] = None
```

Mais déclare explicitement `q` comme étant un paramètre de requête.

Gardez à l'esprit que la partie la plus importante pour rendre un paramètre optionnel est :

```Python
= None
```

ou :

```Python
= Query(None)
```

### `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。

这个函数执行 I/O（输入/输出）操作，需要等待内容写进磁盘。
