如何为任意键设计JSON模式?

I have the following JSON output data:

我有以下JSON输出数据:

{
   "label_name_0" : 0,
   "label_name_5" : 3,
   .
   .
   .
   "label_name_XXX" : 4
}

The output is simple: a key[1] name associated with integer value. If the key name doesn't change, I can easily come up with JSON Schema similar to this:

输出很简单:与整数值关联的关键[1]名称。如果键名不变，我可以很容易地得到类似以下的JSON模式:

    {
        "type": "array"
        "title": "Data output",
        "items" :{ 
            "properties": {
                "label_name": {
                   "type": "integer",
                   "default": 0,
                   "readonly": True,
            }
        }
    },

Since the key name itself is not known and keep changing, I have to design schema for it. The only thing I know is that the key is string and not more than 100 characters. How do I define a JSON Schema for the key lable_name_xxx that keeps changing.

由于键名本身不为人知，并且不断变化，所以我必须为它设计模式。我只知道键是字符串，不超过100个字符。如何为不断变化的关键lable_name_xxx定义一个JSON模式。

On json-schema.org you will find something appropriate in the Advanced Examples section. You can define patternProperties inside an object.

在json-schema.org上，您将在高级示例部分找到一些合适的内容。您可以在对象内部定义模式属性。

{
    "type": "object",
    "properties": {
        "/": {}
    },
    "patternProperties": {
        "^(label_name_[0-9]+)+$": { "type": "integer" }
    },
    "additionalProperties": false,
 }

The regular expression (label_name_[0-9]+)+ should fit your needs. In JSON Schema regular expressions are explicitly anchored with ^ and $. The regular expressions defines, that there has to be at least one property (+). The property consists of label_name_ and a number between 0 and 9 whereas there has to be at least one number ([0-9]+), but there can also arbitrary many of them.

正则表达式(label_name_[0-9]+)应该适合您的需要。在JSON模式正则表达式是明确固定^和$。正则表达式定义，必须至少有一个属性(+)。属性由label_name_和一个介于0和9之间的数字组成，而必须至少有一个数字([0-9]+)，但是也可以有很多。

By setting additionalProperties to false it constrains object properties to match the regular expression.

通过将additionalProperties设置为false，它限制了对象属性与正则表达式匹配。

As Konrad's answer stated, use patternProperties. But use in place of properties, which is not needed, and I think Konrad just pasted from his reference example that was expecting a path starting with /. In the example below, the pattern match regex .* accepts any property name and I am allowing types of string or null only by using "additionalProperties": false.

正如Konrad的回答所说，使用模式属性。但是，使用不需要的属性，我认为Konrad只是从他的引用示例中粘贴过来的，它期望从/开始的路径。在下面的示例中，模式匹配regex .*接受任何属性名，我只允许使用“additionalProperties”:false来表示字符串类型或null类型。

  "patternProperties": {
    "^.*$": {
      "anyOf": [
        {"type": "string"},
        {"type": "null"}
      ]
    }
  },
  "additionalProperties": false
