属性的内容依赖于另一个属性值

Question

我有以下架构，"works"，但不强制执行它所需的所有规则。

我收到 JSON 一系列具有 templateType 和 data 属性的问题。每种类型都有不同的模板，类型必须符合模板（否则客户不知道如何布局数据）。

架构将 templateType 作为枚举进行验证，并且数据符合其中一个模板，但类型和数据结构之间没有关联（例如，我可以得到 templateType yesNo and data structure for multiSelect).

我希望它能验证 templateType 是否与数据结构匹配。我无法更改生成的 JSON 的格式，只能更改验证它的模式。 None 我看过的问题似乎提供了解决方案。

如需帮助，可以将架构粘贴到 http://jeremydorn.com/json-editor/ 处的编辑器中，它根据输入到表单中的选择和数据从架构和 JSON 数据生成表单。

{
  "definitions": {
    "question": {
      "type": "array",
      "title": "Question",
      "items": {
        "$ref": "#/definitions/template"
      }
    },
    "template": {
      "type": "object",
      "title": "Question template",
      "required": ["templateType","data"],
      "properties": {
        "templateType": {
          "type": "string",
          "enum": ["yesNo","multiSelect"]
        },
        "data": {
          "oneOf": [
            {"$ref": "#/definitions/yesNo"},
            {"$ref": "#/definitions/multiSelect"}
          ]
        }
      }
    },
    "yesNo": {
      "type": "object",
      "title": "Yes/No question",
      "additionalProperties": false,
      "properties": {
        "label": {
          "type": "string"
        }
      }
    },
    "multiSelect": {
      "type": "array",
      "title": "Multi-select question",
      "items": {
        "type": "string",
        "title": "Label for option",
        "additionalProperties": false
      }
    }
  },

    "$ref": "#/definitions/question"
  }
}

您是否考虑过在架构中使用 if、then、else 关键字？他们是 JSON Schema draft-07

的一部分

看起来像这样：

{
  "definitions": {
    "question": {
      "type": "array",
      "title": "Question",
      "items": {
        "$ref": "#/definitions/template"
      }
    },
    "template": {
      "type": "object",
      "title": "Question template",
      "required": ["templateType","data"],
      "properties": {
        "templateType": {
          "type": "string",
          "enum": ["yesNo","multiSelect"]
        },
        "data": {
          "if": { "properties": { "templateType": { "pattern": "^yesNo$" } } },
          "then": { "$ref": "#/definitions/yesNo" },
          "else": { "$ref": "#/definitions/multiSelect" }
        }
      }
    },
    "yesNo": {
      "type": "object",
      "title": "Yes/No question",
      "additionalProperties": false,
      "properties": {
        "label": {
          "type": "string"
        }
      }
    },
    "multiSelect": {
      "type": "array",
      "title": "Multi-select question",
      "items": {
        "type": "string",
        "title": "Label for option",
        "additionalProperties": false
      }
    }
  },
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "array",
  "items": {
    "$ref": "#/definitions/question"
  }
}

如果您的验证器不支持 if/then/else，替代方案可能是：

{
  "definitions": {
    "question": {
      "type": "array",
      "title": "Question",
      "items": {
        "$ref": "#/definitions/template"
      }
    },
    "template": {
      "type": "object",
      "title": "Question template",
      "required": ["templateType","data"],
      "anyOf": [
        {
          "properties": {
            "templateType": { "type": "string", "pattern": "yesNo" },
            "data": { "$ref": "#/definitions/yesNo" }
          }
        },
        {
          "properties": {
            "templateType": { "type": "string", "pattern": "multiSelect" },
            "data": { "$ref": "#/definitions/multiSelect" }
          }
        }
      ]
    },
    "yesNo": {
      "type": "object",
      "title": "Yes/No question",
      "additionalProperties": false,
      "properties": {
        "label": {
          "type": "string"
        }
      }
    },
    "multiSelect": {
      "type": "array",
      "title": "Multi-select question",
      "items": {
        "type": "string",
        "title": "Label for option",
        "additionalProperties": false
      }
    }
  },
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "array",
  "items": {
    "$ref": "#/definitions/question"
  }
}
