由于这种情况下（不使用 `Annotated`）我们必须把函数中的默认值 `None` 替换为 `Query()`，因此需要通过参数 `Query(default=None)` 来设置默认值，它起到同样的作用（至少对 FastAPI 来说）。

所以：

```Python
q: str | None = Query(default=None)
```

...会让参数变成可选，默认值为 `None`，等同于：

```Python
q: str | None = None
```

但使用 `Query` 的版本会显式把它声明为一个查询参数。

然后，我们可以向 `Query` 传入更多参数。本例中是适用于字符串的 `max_length` 参数：
