JSON 架构具有不同属性的嵌套对象

Question

整个 JSON 文件相当大，所以我只取出了我遇到问题的小节。

    }
}

我拥有的当前 JSON 架构定义是：

{
  "$schema":"http://json-schema.org/schema#",
  "type":"object",
  "properties":{
     "diagrams":{
        "type":"object"
     }
  },
  "required":[
     "diagrams",
  ]
}

我遇到的问题是图表中包含多个对象，其名称为随机字符串，例如“5f759d15cd046720c28531dd”。

Then within that object there are properties such as (_id, offsetX) which I want to express as well as a nodes object, which again contains multiple objects with arbitrary names eg ("5f9f5c3ccd046720c28531e4", "5f9f5c3ccd046720c28531e5", ...) which have一个独特的节点定义，其中一些节点与其他节点具有不同的属性（nodeID、type、data vs nodeID、type、data、coords）。

我的问题是所有这些任意的东西，例如随机名称以及每个节点的不同属性。 如何将其转换为 1 JSON 模式定义，它涵盖了如何制作图表/节点的所有情况。

Answer 1

您可以使用additionalProperties或patternProperties来做到这一点。

additionalProperties适用于未在properties或patternProperties中声明的任何属性。

{
  "type": "object",
  "additionalProperties": {
    "type": "object",
    "properties": {
      "_id": { ... },
      "offsetX": { ... },
      ...
    }
  }
}

您的属性名称似乎始终是十六进制数字。 如果您想强制这些属性名称始终是十六进制数字，您可以使用patternProperties 。 任何与正则表达式匹配的属性都必须符合该模式。

{
  "type": "object",
  "patternProperties": {
    "^[0-9a-f]{24}$": {
      "type": "object",
      "properties": {
        "_id": { ... },
        "offsetX": { ... },
        ...
      }
    }
  },
  "additionalProperties": false
}
