http://www.jsonschemavalidator.net/ 似乎不尊重 "uniqueitems": true 或 "additionalProperties": false

Question

我一直在阅读有关如何定义 json 模式来保存不同形状对象的列表：人员、地址、车辆。部分研究使我找到了建议有用的补充的帖子。例如添加 "uniqueitems": true 以便列表不包含重复项。

我发现网站 http://www.jsonschemavalidator.net/ 在验证我的架构和 json 数据方面非常有用，但我无法弄清楚我在这两个方面都做错了什么

"additionalProperties": false 

和

"uniqueitems": true

这是我的示例架构和数据：

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "description": "an array of Insurable Items",
  "type": "array",

        },
        "registrationletter": {

        },
        "description": {
          "type": "string"
        }
      },
      "additionalProperties": false
    }
  }
}

数据：

[
  {
    "person": {
      "id": "123456789-01",
      "title": "Mr",
      "firstname": "Joe",
      "lastname": "blogs"
    },
    "badadditional": "thing"
  },
  {
    "address": {
      "id": "123456789-A",
      "line1": "1 The Mall",
      "line2": "Westminster",
      "line3": "London",
      "postcode": "SW1A 1AA"
    }
  },
  {
    "address": {
      "id": "123456789-A",
      "line1": "1 The Mall",
      "line2": "Westminster",
      "line3": "London",
      "postcode": "SW1A 1AA"
    }
  },
  {
    "vehicle": {
      "id": "123456789-01-01",
      "vehiclecode": "string",
      "registrationyear": "string",
      "registrationletter": "string",
      "registrationnumber": "string",
      "description": "string",
      "badadditional": "other thing"
    }
  }
]

如果您将这些复制到 http://www.jsonschemavalidator.net/ 架构验证器中，尽管存在

，但它不会报告任何问题

"badadditional": "thing"

和

"badadditional": "other thing"

以及重复的地址对象。

我一直在搜索 stackoverflow [标记为 json.net]、阅读（以及其他）、http://grokbase.com、http://json-schema.org，并且我正在努力起草 04。

我也试过https://jsonschemalint.com/#/version/draft-04/markup/json，但这也没有抱怨。

任何人都可以将我指向其他验证器、json 架构文档和示例，或者如果很明显，请告诉我我做错了什么？

Answer 1

additionalProperties 工作得很好。问题是您使用了OneOf 而不是oneOf。 JSON Schema 关键字区分大小写，因此验证器无法识别此关键字并忽略它以及它定义的所有内容。

uniqueItems 有两个问题。首先是另一个区分大小写的问题。您已使用uniqueitems。另一个问题是它在错误的地方。它是 items 架构（它是一个对象）的一部分，而它应该是根架构（它是一个数组）的一部分。

所以，修正你的大小写并将uniqueItems 上移一级，它应该会按预期工作。
