JSON 模式验证条件

Question

所以我有这个模式，我正在尝试验证它，但也包括条件。我发现了一些以前提出的问题并遵循了提供的答案，但是我无法正确验证我的架构。

我遵循了这个 post 的答案：但它不起作用

这是我的架构。基本上它应该需要基于 commodityType 的某些字段，但它不起作用并且模式验证器会抛出各种错误。我不确定我做错了什么...

我还应该补充一点，我正在使用 npm jsonschema 来处理模式...

Answer 1

在你有类似 "type": ["integer", null], 的地方，它应该是 "type": ["integer", "null"],。 type 接受一个字符串数组。它不起作用，因为 null 不是字符串。

Answer 2

您可以将 anyOf 更改为 allOf，并删除所有 else: false 子句，这至少会使错误（发出时）更有帮助。

此外，if/then/else 直到第 7 版草案才引入，因此如果您使用的评估器不支持该版本，这些关键字将被完全忽略。
