그래서 `Query`를 필수값으로 만들어야 할 때면, 첫 번째 인자로 `...`를 사용할 수 있습니다:

```Python hl_lines="7"
{!../../docs_src/query_params_str_validations/tutorial006.py!}
```

/// info | "정보"

이전에 `...`를 본적이 없다면: 특별한 단일값으로, <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">파이썬의 일부이며 "Ellipsis"라 부릅니다</a>.

이렇게 하면 **FastAPI**가 이 매개변수는 필수임을 알 수 있습니다.

本例中，因为使用的是 Bearer Token，该响应头的值应为 `Bearer`。

实际上，忽略这个附加响应头，也不会有什么问题。

之所以在此提供这个附加响应头，是为了符合规范的要求。

说不定什么时候，就有工具用得上它，而且，开发者或用户也可能用得上。

这就是遵循标准的好处……
