java - 如何验证 json 模式中的 UUID 属性字段？

Question

   {
  "status": 200,
  "id": "123e4567-e89b-12d3-a456-426655440000",
  "shop": {
    "c73bcdcc-2669-4bf6-81d3-e4ae73fb11fd": {
      "123e4567-e89b-12d3-a456-426655443210": {
        "quantity": {
          "value": 10
        }
      },
      "123e4567-e89b-12d3-a456-426655443211": {
        "quantity": {
          "value": 20
        }
      }
    }
  }
}

这是我的 json 响应。我想验证字段“c73bcdcc-2669-4bf6-81d3-e4ae73fb11fd”，“123e4567-e89b-12d3-a456-426655443210”和“123e4567-e89b-12d3-a456-426655443211”，每次点击时都是唯一的端点。

基于@pxcv7r 的回答:

To validate UUID in particular, you may use format in JSON schema, which provides built-in support for the UUID syntax: { "type": "string", "format": "uuid" }

See https://json-schema.org/understanding-json-schema/reference/string.html

此外，您可以使用 "propertyNames" 的组合和 "unevaluatedProperties"避免需要任何正则表达式:

{
  "$schema": "https://json-schema.org/draft/2019-09/schema",
  "type": "object",
  "properties": {
    "status": {
      "type": "integer"
    },
    "id": {
      "type": "string",
      "format": "uuid"
    },
    "shop": {
      "type": "object",
      "minProperties": 1,
      "maxProperties": 1,
      "propertyNames": {
        "format": "uuid"
      },
      "unevaluatedProperties": {
        "type":"object",
        "minProperties": 1,
        "propertyNames": {
          "format": "uuid"
        },
        "unevaluatedProperties": {
          "title": "single variant of a shop",
          "type": "object",
          "properties": {
            "quantity": {
              "type": "object",
              "properties": {
                "value": {
                  "type": "integer"
                }
              }
            }
          }
        }
      }
    }
  }
}
