我正在尝试使用tv4. 它正在工作并且验证返回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 模式

{
    "$schema": "http://json-schema.org/draft-07/schema",
    "$id": "http://example.com/example.json",
    "type": "object",
    "title": "The root schema",
    "description": "The root schema comprises the entire JSON document.",
    "default": {},

    "required": [
        "checked",
        "result"
    ],
    "properties": {
        "checked": {
            "$id": "#/properties/checked",

            ]
        },
        "result": {

在 JSON Schema 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这些属性。要使它们成为可选，请删除该关键字："required": ["first", "second", "third"]
