在子条件下验证对象属性

Question

我编写了以下 JSON 模式验证多个设备组件的目标图像版本，包含多个组件的活动版本和非活动版本，即 foo、bar。

我如何防止例如如果组件名称是 component2，它只包含 active 属性而不需要 inactive 属性?

{
  "$schema": "http://json-schema.org/draft-07/schema",
  "$id": "config.json",
  "type": "object",
  "title": "Config parameters",
  "required": [
    "Versions"
  ],
  "properties": {
    "Versions": {
      "$id": "#/properties/Versions",
      "type": "array",
      "minItems": 1,
      "additionalItems": false,
      "items": {
        "$id": "#/properties/Versions/items",
        "title": "Version Info",
        "description": "Version information",
        "type": "object",
        "properties": {
          "foo": {
            "$ref": "#/properties/Versions/items/definitions/image-info"
          },
          "bar": {
            "$ref": "#/properties/Versions/items/definitions/image-info"
          }
        },
        "definitions": {
          "image-info": {
            "type": "object",
            "properties": {
              "component1": {
                "$ref": "#/properties/Versions/items/definitions/image-settings"
              },
              "component2": {
                "$ref": "#/properties/Versions/items/definitions/image-settings"
              }
            },
            "additionalProperties": false
          },
          "image-settings": {
            "type": "object",
            "properties": {
              "active": {
                "$ref": "#/properties/Versions/items/definitions/image-version"
              },
              "inactive": {
                "$ref": "#/properties/Versions/items/definitions/image-version"
              }
            },
            "additionalProperties": false
          },
          "image-version": {
            "type": "string",
            "pattern": "^20[0-9]{2}-[01][0-9]-[0-3][0-9]-[0-9]{2}$"
          }
        }
      }
    }
  },
  "additionalProperties": false
}

我希望以下 JSON 被视为无效，因为 component2 包含 inactive 属性

{
  "Versions": [
    {
      "foo": {
        "component1": {
          "active": "2021-11-15-01",
          "inactive": "2021-11-15-00"
        }
      }
    },
    {
      "bar": {
        "component2": {
          "active": "2021-11-15-03",
          "inactive": "2021-11-15-04"
        }
      }
    }
  ]
}

但我希望以下内容被视为有效 JSON

{
  "Versions": [
    {
      "foo": {
        "component1": {
          "active": "2021-11-15-01",
          "inactive": "2021-11-15-00"
        }
      }
    },
    {
      "bar": {
        "component2": {
          "active": "2021-11-15-03"
        }
      }
    }
  ]
}

Answer 1

假设您不想修改 image-setting 的定义，并希望尽可能避免重复，您可以修改 component2 的定义以禁止 inactive使用 not 关键字。

当您使用 JSON 架构的参考和 draft-07 时，您需要将该参考包含在 allOf 中。（如果您使用 2019-09 或更高版本，则不会，因为 $ref 现在可以与其他关键字一起使用。）

{
  "allOf": [
    {
      "$ref": "#/properties/Versions/items/definitions/image-settings"
    }, {
      "not": {
        "required": ["inactive"]
      }
    }
  ]
}
