http://www.jsonschemavalidator.net/ 似乎不支持 "uniqueitems": true 或 "additionalProperties": false

Question

我一直在阅读如何定义 json 架构来保存不同形状对象的列表：人、地址、车辆。部分研究让我看到了一些帖子，其中提出了有用的补充建议。例如添加 "uniqueitems": true 以便列表不包含重复项。

我发现站点 http://www.jsonschemavalidator.net/ 在验证我的模式和 json 数据方面非常有用，但我无法弄清楚我在这两个方面做错了什么

"additionalProperties": false

和

"uniqueitems": true

这是我的示例架构和数据：

{

          "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"

和重复的地址对象。

我一直在搜索 Whosebug [标记为 json.net]，正在阅读（除其他外）http://grokbase.com, http://json-schema.org，并且我正在研究 draft-04。

我也试过 https://jsonschemalint.com/#/version/draft-04/markup/json 但那也没有问题。

任何人都可以向我指出其他验证器、json 架构文档和示例，或者让我知道我做错了什么（如果很明显）吗？

Answer 1

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

uniqueItems 你有两个问题。第一个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。当它应该是根模式（数组）的一部分时，它是 items 模式（一个对象）的一部分。

因此，修复您的大小写并将 uniqueItems 提高一级，它应该会按预期工作。
