【问题描述】：
我正在尝试定义一个 json 模式，该模式具有多个对象的通用枚举类型，然后根据选择的枚举，定义枚举的可能组合以及所需的其他元素。 该示例具有 {IDNumber, Color, Furniture Type} 的家具数据，然后根据从枚举列表中选择的类型，获取分配有不同枚举的函数。我还添加了一个“分配的人员”示例作为额外元素。
我认为我使用 anyof 和 const 正确地做到了这一点。但是，当我使用 XMLSpy Pro 2020 进行测试时，它会生成无效的 json 示例，并且当我尝试验证无效示例时，它也会通过....所以，1) 我表达得很好吗？ 2）我做错了什么？ 3）有更好的方法吗？ 4) 是工具还是 json 模式？ 请帮忙。

XMLSpy 验证为正常的无效 JSON 示例：（它链接到我在信息页面中的架构） 灯不应该允许 6x4 作为函数......
{
"FurnitureData": [
{
"Color": {
"value": "WOOD",
"readOnly": "a",
"custom value": "a"
},
"IDNumber": {
"value": "a",
"readOnly": true
},
"Furniture Type": {
"value": "LAMP",
"custom value": "a"
},
"Function": {
"value": "6' x 4'",
"custom value": "a"
}
}
]
}
另一个无效示例...椅子具有“分配的人员”并且显示了错误的类型值，但这也可以验证...
{
"FurnitureData": [
{
"Color": {
"value": "WOOD",
"readOnly": "a",
"custom value": "a"
},
"IDNumber": {
"value": "a",
"readOnly": true
},
"Furniture Type": {
"value": "CHAIR",
"custom value": "a"
},
"Function": {
"value": "6' x 4'",
"custom value": "a"
}
}
]
}
这是遵循中的建议 See enum section using anyof
也许我必须使用 if-then 构造？在这里，我在 any-of 中尝试了 if-then，但我也得到了 json 的验证，它允许来自其他家具类型的枚举......
