/// note | 注意

路径参数总是必需的，因为它必须是路径的一部分。即使你将其声明为 `None` 或设置了默认值，也不会产生任何影响，它依然始终是必需参数。

///

## 按需对参数排序 { #order-the-parameters-as-you-need }

/// tip | 提示

如果你使用 `Annotated`，这点可能不那么重要或必要。

///

假设你想要将查询参数 `q` 声明为必需的 `str`。

并且你不需要为该参数声明其他内容，所以实际上不需要用到 `Query`。

但是你仍然需要为路径参数 `item_id` 使用 `Path`。并且出于某些原因你不想使用 `Annotated`。
