jsonschema - 在对象数组的情况下，如何删除 Json 模式中顺序的依赖关系

Question

我有一个 Json 架构模板，其中包含对象数组。我需要使用该模板验证 Json 输入。但我希望这不应该依赖于数组中对象的顺序。

下面我们在模板中有 3 个不同对象的数组，即ABS、端点和调度。我想从这里删除顺序的依赖性。我可以在 Json 输入模式中提供项目的 ant 顺序。它不应该依赖于模板。我正在使用“ajv”节点 js 模板来使用模板数据验证 Json 输入。任何帮助，将不胜感激。谢谢。

Answer 1

items 关键字可以采用单个架构，也可以采用一个或多个架构。

如果您提供架构数组，则第一个架构必须应用于数组中的第一个项目，然后第二个架构应用于数组中的第二个项目，依此类推，对于 n 个架构和项目。

要更改架构以使 items 的值成为单个架构，请将架构数组包装在 oneOf 中。这意味着数组中的每一项都必须对于 oneOf 数组值中的模式之一有效。
