JSON架构验证条件

Question

所以我有这个模式，我正在尝试验证它，但也包括条件。我找到了一些以前问过的问题，并遵循了提供的答案，但我无法正确验证我的模式。

我遵循了这篇文章的答案：堆栈溢出JSON模式验证，但它不起作用

这是我的模式。基本上，它应该需要基于commodityType的某些字段，但它不起作用，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

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(在发出时(更有帮助。

此外，如果/then/else直到草案版本7才引入，那么如果您使用的评估器不支持该版本，那么这些关键字将被完全忽略。

Answer 2

在有类似"type": ["integer", null],的东西的地方，它应该是"type": ["integer", "null"],。type采用字符串数组。它不起作用，因为null不是字符串。
