    Falls Sie das `...` bisher noch nicht gesehen haben: Es ist ein spezieller einzelner Wert, <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">Teil von Python und wird „Ellipsis“ genannt</a> (Deutsch: Ellipse).

    Es wird von Pydantic und FastAPI verwendet, um explizit zu deklarieren, dass ein Wert erforderlich ist.

    如果你之前没见过 `...` 这种用法：它是一个特殊的单独值，它是 <a href="https://docs.python.org/3/library/constants.html#Ellipsis" class="external-link" target="_blank">Python 的一部分并且被称为「省略号」</a>。
    Pydantic 和 FastAPI 使用它来显式的声明需要一个值。

这将使 **FastAPI** 知道此查询参数是必需的。

### 使用`None`声明必需参数
