Json Schema - 如何使任意两个或多个属性成为必需

Question

我有这个父架构：

{
    "definitions": {
        "parcel": {
            "type": "object",
            "properties": {
                "id": {
                    "type": "string"
                },
                "accountNumber": {
                    "type": "string"
                },
                "parcelNumber": {
                    "type": "string"
                },
                "propertyType": {
                    "type": "string"
                },
                "address": {
                    "$ref": "address.json#/definitions/address"
                },
                "coordinates": {
                    "$ref": "coordinates.json#/definitions/coordinates"
                }
            },
            "required": ["accountNumber", "parcelNumber"]
        }
    }
}

以下是引用的子模式：

{
    "definitions": {
        "address": {
            "type": "object",
            "properties": {
                "addressString": {
                    "type": "string",
                    "addressType": {
                        "enum": ["residential", "business"]
                    }
                },
                "required": ["addressString"]
            }
        }
    }
}

    {
    "definitions": {
        "coordinates": {
            "type": "object",
            "properties": {
                "latitude": {
                    "type": "number"
                },
                "longitude": {
                    "type": "number"
                },
                "projection": {
                    "type": "string"
                }
            },
            "required": ["latitude ", "longitude", " projection"]
        }
    }
}

我想将以下条件应用于父架构。

1. 提供地址或坐标或两者都提供。
2. 如果既没有提供地址也没有提供坐标，则验证失败。

Answer 1

您的anyOf解决方案有效。您可以通过从anyOf属性组中分离固定的必需属性（accountNumber 和parcelNumber）来使其更简洁：

{
  "type": "object",
  "required": [
    "accountNumber",
    "parcelNumber"
  ],
  "anyOf": [
    {"required" : ["address"]},
    {"required" : ["coordinates"]}
  ],
  "properties": {
    "id": {
      "type": "string"
    },
    "accountNumber": {
      "type": "string"
    },
    "parcelNumber": {
      "type": "string"
    },
    "propertyType": {
      "type": "string"
    },
    "address": {
      "type": "object",
      "properties": {
        "addressString": {
          "type": "string"
        },
        "addressType": {
          "enum": [
            "residential",
            "business"
          ]
        }
      },
      "required": [
        "addressString"
      ]
    },
    "coordinates": {
      "type": "object",
      "properties": {
        "latitude": {
          "type": "number"
        },
        "longitude": {
          "type": "number"
        },
        "projection": {
          "type": "string"
        }
      },
      "required": [
        "latitude",
        "longitude",
        "projection"
      ]
    }
  }
}
