JSON Schema 中基于 $ref 枚举的对象属性

Question

我已经看过了：

• Properties based on enum value in JSON Schema
• JSON schema for dynamic properties
• JSON Schema $ref for properties

---

我需要我的 JSON 模式来强制一个对象具有枚举中的所有属性，我不知道如何。

stuff.list.json

注意：想象一下，但要长得多。

{
    "$schema": "https://json-schema.org/draft/2020-12/schema",
    "$id": "https://example.com/product.schema.json",
    "title": "ListOfStuff",
    "description": "List of stuff",
    "enum": [
        "Thing1",
        "Thing2",
        "Thing3"
    ],
    "uniqueItems": true
}

stuff.schema.json

{
    "$schema": "https://json-schema.org/draft/2020-12/schema",
    "$id": "https://example.com/product.schema.json",
    "title": "Stuff Defined",
    "description": "Stuff in detail",
    "type": "object",
    "properties": {
        /* a property for each enum value of stuff.list.json  */: { <----- ???
            "type": "array",
            "items": { /* Schema for each item */ }
        }
    },
    "required": [ /* $ref: ./stuff.list.json ?? */ ]
 }

我希望它强制执行的输出是：

 {
     "Thing1": [],
     "Thing2": [],
     "Thing3": []
 }

您在寻找required keyword 吗？您可以将其放在定义中并稍后引用：

"$defs": {
  "required_properties": {
    "required": [
      "Thing1",
      "Thing2",
      "Thing3"
    ]
  }
},
...

然后在您的主架构中：

{
  ...,
  "type": "object",
  "$ref": "stuff.list.json#/$defs/required_properties",
  ...,
}
