假设以下 JSON 来自 Google GeoCoding API
{
"lon": 1.2345678,
"lat": 1.2345678,
"formatted_adress": "Sunny Ave, 01234 Dev City, New Devland",
"address_components": [
{
"long_name": "Sunny Ave",
"short_name": "Sunny Ave",
"types": [
"route"
]
},
{
"long_name": "Downtown",
"short_name": "Downtown",
"types": [
"sublocality_level_1",
"sublocality",
"political"
]
},
{
"long_name": "Dev City",
"short_name": "Dev City",
"types": [
"locality",
"political"
]
},
{
"long_name": "Dev City",
"short_name": "Dev City",
"types": [
"administrative_area_level_3",
"political"
]
},
{
"long_name": "Somwherechester",
"short_name": "SC",
"types": [
"administrative_area_level_1",
"political"
]
},
{
"long_name": "New Devland",
"short_name": "DE",
"types": [
"country",
"political"
]
},
{
"long_name": "01234",
"short_name": "01234",
"types": [
"postal_code"
]
}
]
}
我需要验证所示的数据（类型、属性等）。
除了：
address_components必须包含所有types至少包含 [ locality, country, postal_code] 一个元素的对象。允许包含其他对象。
根据此解决方案https://github.com/orgs/json-schema-org/discussions/191，我设法足够接近types常量字符串。但我无法针对字符串数组进行验证。

{

示例
无效数据 => 没有带有 的对象postal_code。
{
"lon": 1.2345678,
"lat": 1.2345678,
"formatted_adress": "Sunny Ave, 01234 Dev City, New Devland",
"address_components": [
{
"long_name": "Sunny Ave",
"short_name": "Sunny Ave",
"types": [
"route"
]
},
{
"long_name": "Downtown",
"short_name": "Downtown",
"types": [
"sublocality_level_1",
"sublocality",
"political"
]
},
{
"long_name": "Dev City",
"short_name": "Dev City",
"types": [
"locality",
"political"

},
{
"long_name": "Dev City",

]
},
{
"long_name": "New Devland",
"short_name": "DE",
"types": [
"country",

}
]
}
有效数据 => 所有 3 个对象至少具有上述类型之一 - 没有其他（可选）对象
{
"lon": 1.2345678,
"lat": 1.2345678,
"formatted_adress": "Sunny Ave, 01234 Dev City, New Devland",
"address_components": [
{
"long_name": "Dev City",
"short_name": "Dev City",
"types": [
"locality",
"political"
]
},
{
"long_name": "New Devland",
"short_name": "DE",
"types": [
"country",
"political"
]
},
{
"long_name": "01234",
"short_name": "01234",
"types": [
"postal_code"
]
}
]
}
要处理 types 属性中字符串数组的验证并确保至少存在一个必需的类型（locality、country、postal_code），您可以使用 JSON 架构来检查 types 数组是否至少包含其中一个值。以下是您的架构的改进版本：
{ "$schema": "https://json-schema.org/draft/2020-12/schema", "$id": "", "title": "Google API 地理编码", "description": "必要的地址组件。", "type": "object", "required": [ "formatted_adress", "lon", "lat", "address_components" ], "properties": { "formatted_adress": { "type": "string" }, "lon": { "type": "number" }, "lat": { "type": "number" }, "address_components": { "type": "array", "items": { "type": "object", "required": [ "long_name", "short_name", "types" ], "properties": { "long_name": { "type": "string" }, "short_name": { "type": "string" }, "types": { "type": "array", "items": { "type": "string" } } } }, "allOf": [ { "contains": { "properties": { "types": { "type": "array", "contains": { "enum": ["locality"] } } } } }, { "contains": { "properties": { "types": { "type": "array", "contains": { "enum": ["country"] } } } } }, { "contains": { "properties": { "types": { "type": "array", "contains": { "enum": ["postal_code"] } } } } } ] } } } 要点： types 作为数组： types 属性现在正确定义为字符串数组。 contains 关键字：用于确保数组至少包含一个来自指定集合（locality、country、postal_code）的元素。 allOf 用于多项检查：该架构确保 address_components 数组至少包含一个具有地点的对象、一个具有国家/地区的对象和一个具有邮政编码的对象作为类型数组的一部分。此架构将正确验证 address_components 是否包含所需的地址类型。
我想这就是你所要求的。
每个
address_components > types条目应至少包含三种类型关键字之一locality, postal_code, country。
