使用Javascript的可选Json验证

Question

我正在尝试使用tv4验证我的JSON模式。它正在工作，验证返回True。

但是，在我的情况下，JSON集合"first, second, and third"不会一直可用。

在这种情况下，我该如何编写模式？

我的JSON数据

{
"checked": "OK",
"result": {
"first": {
"label": "First Label",
"value": 1
},
"second": {
"label": "second Label",
"value": 34
},
"third": {
"label": "Third Label",
"value": 28
}
}
}

JSON架构

在JSON模式中，默认情况下，所有属性都是可选的。您的架构根据需要显式声明了这些属性。要使它们可选，请删除关键字："required": ["first", "second", "third"]
