然后，访问如下 URL：

```
http://localhost:8000/items/?q=foo&q=bar
```

你会在*路径操作函数*的*函数参数* `q` 中以一个 Python `list` 的形式接收到多个 `q` *查询参数* 的值（`foo` 和 `bar`）。

因此，该 URL 的响应将会是：

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

/// tip | 提示

要声明类型为 `list` 的查询参数（如上例），你需要显式地使用 `Query`，否则它会被解释为请求体。

## Using `Union` or `Optional` { #using-union-or-optional }

If your code for some reason can't use `|`, for example if it's not in a type annotation but in something like `response_model=`, instead of using the vertical bar (`|`) you can use `Union` from `typing`.

For example, you could declare that something could be a `str` or `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):

    assertThat(url.queryParameterValues("bar")).isEqualTo(listOf(null as String?))
    assertThat(url.queryParameterValues("baz")).isEqualTo(listOf(null as String?))
  }

  @Test
  fun queryParametersWithEmptyValues() {
    val url = parse("http://host/?foo=&bar=&baz=")
    assertThat(url.querySize).isEqualTo(3)
    assertThat(url.queryParameterNames).containsExactlyInAnyOrder("foo", "bar", "baz")
