使用JSON模式强制对象非空性

问题描述

我们可以如下强制实施类型为object的空属性:

We can enforce empty attribute of type object as follows:

{
   "description": "voice mail record",
   "type": "object",
   "additionalProperties": false,
   "properties": {}
}

如此处所述.

现在我要验证哪个属性

1. 是对象类型，
2. 没有任何预定义的属性
3. 可以具有字符串或数字类型的属性
4. 不能为空

强制执行非空(第4点)是我无法猜测的.如上面的示例，这与强制执行空性有些相反.我当前的json模式摘录如下:

Enforcing non-emptyness (point 4) is what I am unable to guess. This is somewhat opposite of enforcing emptyness as in above example. My current json schema excerpt looks like this:

"attribute": 
{
    "type": "object",
    "additionalProperties": { "type": ["string","number","integer"] }
}

但是，上面没有强制非空性.我该怎么做?

But above does not enforce non-emptyness. How can I accomplish this?

推荐答案

类似 minProperties 是您想要的.

Sounds like minProperties is what you want.

{
    "type": "object",
    "additionalProperties": {"type": ["string", "number", "integer"]},
    "minProperties": 1
}

还有 maxProperties ，它可以用作您链接到的相反问题的替代解决方案.

There is also maxProperties, which can be used as an alternative solution to the opposite question that you linked to.
