问题描述
所以我有这个模式，我正在尝试验证它，但也包括条件。我发现了一些先前提出的问题，并按照提供的答案进行了操作，但是我无法使自己的模式正确验证。
我遵循了这篇文章的答案：Stack Overflow JSON Schema Validation，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，但是它不起作用，并且模式验证器会抛出各种错误。不确定我在做什么错...
我还应该补充一点，我正在使用npm jsonschema处理模式...

解决方法
在"type": ["integer",null],之类的地方，应该为"type": ["integer","null"],。 type采用字符串数组。由于null不是字符串，因此无效。
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（在发出错误时）更加有用。
此外，如果直到第7版草案才引入/ then / else，所以如果您使用的评估程序不支持该版本，则这些关键字将被完全忽略。
