类似字典的 JSON 模式

发布于12月09日

我有一个json对象，它可以包含任意数量的具有特定规范的嵌套对象，例如:

{
  "Bob": {
    "age": "42",
    "gender": "male"
  },
  "Alice": {
    "age": "37",
    "gender": "female"
  }
}

And would like to have a schema looking something like:

{
  "type": "object",
  "propertySchema": {
    "type": "object",
    "required": [
      "age",
      "gender"
    ],
    "properties": {
      "age": {
        "type": "string"
      },
      "gender": {
        "type": "string"
      }
    }
  }
}

I know that I can turn that into array and push 'name' inside the objects. In that case my schema would look like:

{
  "type": "array",
  "items": {
    "type": "object",
    "required": [
      "name",
      "age",
      "gender"
    ],
    "properties": {
      "name": {
        "type": "string"
      },
      "age": {
        "type": "string"
      },
      "gender": {
        "type": "string"
      }
    }
  }
}

but I would like to have a dictionary-like structure. Is it possible to make such schema?

推荐答案

additionalProperties is your keyword:

{
    "type" : "object",
    "additionalProperties" : {
        "type" : "object",
        "required" : [
            "age",
            "gender"
        ],
        "properties" : {
            "age" : {
                "type" : "string"
            },
            "gender" : {
                "type" : "string"
            }
        }
    }
}

additionalProperties可以具有具有不同含义的下列值:

"additionalProperties": false No more properties are allowed at all.
允许其他"additionalProperties": true个属性.这是默认行为.
"additionalProperties": {"type": "string"} Additional properties (of arbitrary name) are allowed, as long as their value follows the given type ("string" here).
"additionalProperties": {*any schema*}个附加属性必须满足提供的模式，例如上面提供的示例.
