从json-schema引用远程枚举值

问题描述

在我的模式定义中，我有一个类型，具有一个整数属性，该属性应该是固定"属性中的任何一个.一组数字.问题在于，该固定集"不正确.可能会经常更改.

In my schema definitions, I have a type, with an integer property which should be any of a "fixed" set of numbers. The problem is that this "fixed set" may be changed often.

   "person": {
      "type": "object",
      "properties": {
        "aproperty": {
          "type": "integer",
          "enum": [1, 12, 30 ... , 1000]
        },
      }
    },

是否有任何方法可以从远程服务(该服务具有最新设置)引用此数组?

Is there any way to reference this array from a remote service (which will have the most updated set)?

   "person": {
      "type": "object",
      "properties": {
        "aproperty": {
          "type": "integer",
          "$ref": "http://localhost:8080/fixed_set"
        },
      }
    },

我尝试了$ ref，但是没有运气.如果"ref"是解决方案的一部分，后端后端应该返回什么?

I tried $ref, but no luck.If "ref" is part of the solution, what should de backend return?

{
  "enum": [1, 12, 30 ... , 1000]
}

或

  "enum": [1, 12, 30 ... , 1000]

或

  [1, 12, 30 ... , 1000]

推荐答案

主模式:

    {
      "$schema": "https://json-schema.org/draft/2019-09/schema",
      "type": "object",
      "properties": {
        "aproperty": {
          "type": "integer",
          "$ref": "http://localhost:8080/fixed_set"
        },
      }
    }

子模式:

{
  "$id": "http://localhost:8080/fixed_set",
  "enum": [1, 12, 30 ... , 1000]
}

请注意，必须使用支持draft2019-09的评估程序，$ref才能被识别为同级关键字.否则，您需要将其包装在allOf中:

Note that you must be using an evaluator that supports draft2019-09 for the $ref to be recognized as a sibling keyword. Otherwise, you need to wrap it in an allOf:

    {
      "type": "object",
      "properties": {
        "aproperty": {
          "type": "integer",
          "allOf": [
            { "$ref": "http://localhost:8080/fixed_set" }
          ]
        },
      }
    }
