JSON模式-需要所有属性 [英] JSON Schema - require all properties

问题描述

JSON模式具有properties，required和additionalProperties字段.例如，

JSON Schema features the properties, required and additionalProperties fields. For example,

{
    "type": "object",
    "properties": {
        "elephant": {"type": "string"},
        "giraffe": {"type": "string"},
        "polarBear": {"type": "string"}
    },
    "required": [
        "elephant",
        "giraffe",
        "polarBear"
    ],
    "additionalProperties": false
}

将验证JSON对象，例如:

Will validate JSON objects like:

{
    "elephant": "Johnny",
    "giraffe": "Jimmy",
    "polarBear": "George"
}

但是如果属性列表不是完全 elephant, giraffe, polarBear，则会失败.

But will fail if the list of properties is not exactly elephant, giraffe, polarBear.

我经常将properties的列表复制粘贴到required的列表中，当由于错别字和其他愚蠢的错误导致列表不匹配时，我会遇到烦人的错误.

I often copy-paste the list of properties to the list of required, and suffer from annoying bugs when the lists don't match due to typos and other silly errors.

是否有一种较短的方法来表示所有属性都是必需的，而无需显式命名它们?

推荐答案

您可以只使用"minProperties"属性，而不是显式命名所有字段.

You can just use the "minProperties" property instead of explicity naming all the fields.

{
    "type": "object",
    "properties": {
        "elephant": {"type": "string"},
        "giraffe": {"type": "string"},
        "polarBear": {"type": "string"}
    },
    "additionalProperties": false,
    "minProperties": 3
}
