json-schema 中是否有一种方法可以验证与正则表达式匹配的对象键？

Question

有没有办法让 json 模式验证器验证 json 对象的 keys？例如：

{
    "$schema": "http://json-schema.org/draft-07/schema",
    "type": "object",
    "properties": { // here properties is an object containing user-defined keys that should be alphanumeric or underscore.
        "values": {
            "type": "object",
            "patternProperties": {
                "[a-zA-Z0-9_]+": {
                    "description": "Foo"
                }
            }
        }
    }
}

所以这里有一些应该和不应该通过的例子：

// Should pass:
{
 "values": {
   "myKey1": { "foo": 1 },
   "myKey2_": "bar"
 }
}

// Should fail but no error is shown saying this doesnt match schema:
{
  "values": {
    "m[]": 123
  }
}

我尝试使用 patternProperties，但任何与我的正则表达式不匹配的内容都会被忽略，不会在有问题的行上抛出验证错误。这与 patternProperties 上的文档一致： https://json-schema.org/understanding-json-schema/reference/object.html#pattern-properties

有没有办法做我正在寻找的东西？谢谢

您应该能够使用 additionalProperties 使未通过您所要求的 patternProperties 的对象无效。

By default any additional properties are allowed.

{
"$schema": "http://json-schema.org/draft-07/schema",
"type": "object",
"properties": {
    "values": {
        "type": "object",
        "patternProperties": {
            "[a-zA-Z0-9_]+": {
                "description": "Foo"
            },
            "additionalProperties": false
            }
        }
    }
}

Is there a way in json-schema to validate object keys matching regex?
