如何对 JSON 具有数组的文档使用 JSON 模式验证?
How to use JSON schema validation against JSON document having arrays?
我有 json 文档,其中包含三个主要元素和子元素。这些元素也有数组。我使用 json 模式验证了此文档,但我不确定是否有任何简单的方法可以摆脱数组的重复模式,因为当前模式太长。
JSON 架构:

这个架构有很多问题。我建议您阅读 http://spacetelescope.github.io/understanding-json-schema/ 以更好地理解 JSON Schema。以下是更正后的架构。我会给出一些简短的建议,但不会做太多解释。请阅读 link 了解更多信息。
id
必须是绝对 URL。 “/”无效
- 不要在文档根以外的任何地方使用
id
。它有一些意想不到的特性。最好避免它。
items
关键字应该是模式而不是模式数组。您使用的表格不适用于具有单一类型项目的数组。
required
关键字仅适用于其出现的架构中的属性。子架构需要定义自己的 required
属性。
required
关键字对数组不起作用。请改用 minItems
和 maxItems
。
