JSON文档无法在JSON Schema上进行验证

Question

Json schema和Json Document下面都是有效的json。 它只是因为我无法获得与json模式相关的有效Json文档。

我收到错误消息：不应该有其他属性

    "required": [

    ]
  }
}

Answer 1

架构中缺少"users"属性，因此它是一个附加属性，因此违反了"additionalProperties": false设置。

如果您在架构中定义"users"属性，那么您的文档将有效。

Answer 2

问题出在additionalProperties的位置上。 因为用户是具有大量对象的类型数组。假设项目的属性具有additionalProperties而不是包装器“users”：{}但是“item”：{}

解决方案
