【问题描述】：
我正在为我的项目使用 networknt json 模式验证器。 我在其他 json 模式文件中定义了一个 json 模式和更多定义。 但是当我使用对其他 json 文件的引用时，验证器会抛出 no json schema found (file not found ) 异常。 我让我的 id 看起来像 URL（当然不能通过网络访问，因为它只是 id） 但似乎 networknt 验证器试图检索架构，将其视为 URL？ 标准 json 模式文档说 id 不一定是网络可访问的，所以我不确定它为什么要尝试获取它。 无论如何，我想了解如何为 json 模式文件创建 $id 和 $ref 以使其工作。
示例架构 1：
