使用JSON模式进行属性验证的唯一值 [英] Unique value for a property validation using json schema

问题描述

我有一个JSON对象，如:

{
  "result": [
    {
      "name" : "abc",
      "email": "[e-mail]"
      
    },
    {
      "name": "def",
      "email": "[e-mail]"
     
    },
    {
      "name": "xyz",
      "email": "[e-mail]"
    }
  ]
}

和模式:

{
  "definitions": {},
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "https://example.com/object1607582431.json",
  "title": "Root",
  "type": "object",
  "required": [
    "result"
  ],
  "properties": {
    "result": {
      "$id": "#root/result",
      "title": "Result",
      "type": "array",
      "default": [],
      "uniqueItems": true,
      "items": {
        "$id": "#root/result/items",
        "title": "Items",
        "type": "object",
        "required": [
          "name",
          "email"
        ],
        "properties": {
          "name": {
            "$id": "#root/result/items/name",
            "title": "Name",
            "type": "string"
           
          },
          "email": {
            "$id": "#root/result/items/email",
            "title": "Email",
            "type": "string"
          }
        }
      }
    }
  }
}

我正在寻找一个选项来检查email的唯一性，而不管其名称如何.如何验证每个email应该是唯一的?

解决方案

您不能.除了uniqueItems之外，没有关键字可让您将一个特定的数据值与另一个特定的数据值进行比较.

I have a JSON object like:

{
  "result": [
    {
      "name" : "abc",
      "email": "[e-mail]"
      
    },
    {
      "name": "def",
      "email": "[e-mail]"
     
    },
    {
      "name": "xyz",
      "email": "[e-mail]"
    }
  ]
}

and schema for this:

{
  "definitions": {},
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$id": "https://example.com/object1607582431.json",
  "title": "Root",
  "type": "object",
  "required": [
    "result"
  ],
  "properties": {
    "result": {
      "$id": "#root/result",
      "title": "Result",
      "type": "array",
      "default": [],
      "uniqueItems": true,
      "items": {
        "$id": "#root/result/items",
        "title": "Items",
        "type": "object",
        "required": [
          "name",
          "email"
        ],
        "properties": {
          "name": {
            "$id": "#root/result/items/name",
            "title": "Name",
            "type": "string"
           
          },
          "email": {
            "$id": "#root/result/items/email",
            "title": "Email",
            "type": "string"
          }
        }
      }
    }
  }
}

I am looking for an option to check uniqueness for email irrespective of name. How I can validate that every email should be unique?

解决方案

You can't. There are no keywords that let you compare one particular data value against another, other than uniqueItems, which compares an array element in toto against another.
