json模式验证对象的空数组

Question

var schema = {
  "$schema": "http://json-schema.org/draft-07/schema",
  "$id": "http://example.com/example.json",
  "type": "object",
  "required": [
    "data"
  ],
  "properties": {
    "data": {
      "$id": "#/properties/data",
      "type": "object",
      "required": [
        "id",
        "name",
        "description",
        "groups"
      ],
      "properties": {
        "id": {
          "$id": "#/properties/data/properties/id",
          "type": "integer"
        },
        "name": {
          "$id": "#/properties/data/properties/name",
          "type": "string"
        },
        "description": {
          "$id": "#/properties/data/properties/description",
          "type": "string"
        },
        "groups": {
          "$id": "#/properties/data/properties/groups",
          "type": "array",
          "items": {
            "$id": "#/properties/data/properties/groups/items",
            "anyOf": [
              {
                "$id": "#/properties/data/properties/groups/items/anyOf/0",
                "type": "object",
                "required": [
                  "id",
                  "name",
                  "description"
                ],
                "properties": {
                  "id": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/id",
                    "type": "integer"
                  },
                  "name": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/name",
                    "type": "string"
                  },
                  "description": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/description",
                    "type": "string"
                  }
                }
              }
            ]
          }
        }
      }
    }
  }
};

我有JSON结果：

{
    "data": {
        "id": 1,
        "name": "Contacts",
        "description": "Pre-installed contacts management for your account.",
        "groups": []
    }
}

or

{
    "data": {
        "id": 4,
        "name": "Update Container Sub Type 913",
        "description": "I'll calculate the virtual SQL bus, that should circuit the FTP sensor!",
        "groups": [
            {
                "id": 1,
                "name": "tech",
                "description": "tech description group"
            }
        ]
    }
}

当我验证JSON模式时，第二个有效，第一个 - 无效。 我该如何解决这两者都是有效的？

Answer 1

在JSON架构规范中描述的是2020-12版，可以验证数组中的最小项目数量。只需使用属性minItems

。
您可以写这样的东西：

{
    "$id": "#/properties/data/properties/groups",
    "type": "array",
    "minItems": 1,
    "items": {
       ...
    }
}

已编辑：**这没有回答这个问题**

Option 1：验证者和JSON-SCHEMA版本

Answer 2

已编辑：删除错误的信息。 Option 2：丢弃

anyOf

问题可能是

anyOf

：它的意思是一个或更多这些问题，因此，组不能为空。有关更多信息

但是，当您只有一个类型的项目时，为什么需要

anyOf

？ 尝试：

 {
  "$schema": "http://json-schema.org/draft-07/schema#",

  "type": "object",
  "required": [
    "data"
  ],
  "properties": {
    "data": {
      "$id": "#/properties/data",
      "type": "object",
      "required": [
        "id",
        "name",
        "description",
        "groups"
      ],
      "properties": {
        "id": {
          "$id": "#/properties/data/properties/id",
          "type": "integer"
        },
        "name": {
          "$id": "#/properties/data/properties/name",
          "type": "string"
        },
        "description": {
          "$id": "#/properties/data/properties/description",
          "type": "string"
        },
        "groups": {
          "$id": "#/properties/data/properties/groups",
          "type": "array",
          "items": {
                "$id": "#/properties/data/properties/groups/items/anyOf/0",
                "type": "object",
                "required": [
                  "id",
                  "name",
                  "description"
                ],
                "properties": {
                  "id": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/id",
                    "type": "integer"
                  },
                  "name": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/name",
                    "type": "string"
                  },
                  "description": {
                    "$id": "#/properties/data/properties/groups/items/anyOf/0/properties/description",
                    "type": "string"
                  }
                }
          }
        }
      }
    }
  }
}

因此，您可以摆脱anyOf约束，并验证一个空数组，因为默认情况下允许。 3：条件模式 如果您的验证器不接受空数数（有些确实），则可能有可能使用条件结构来处理某些内容。 。 一行：

如果数组大小为> 0，然后应用“ Anyof”子chema

请让我们知道您如何解决此问题。
