# 路径参数和数值校验

与使用 `Query` 为查询参数声明更多的校验和元数据的方式相同，你也可以使用 `Path` 为路径参数声明相同类型的校验和元数据。

## 导入 Path

首先，从 `fastapi` 导入 `Path`：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

## 声明元数据

你可以声明与 `Query` 相同的所有参数。

例如，要声明路径参数 `item_id`的 `title` 元数据值，你可以输入：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

路径参数总是必需的，因为它必须是路径的一部分。
