Answer 1

因此，您的示例JSON实际上是一个具有三个属性的类型，这就是为什么您生成的模式要求您显式定义每个属性，即使它们实际上是相同的类型。

但是，如果您愿意稍微修改您的示例json：

{
  "categoryMapping": [
    {
      "name": "categoryA",
      "map": ["a","b","c"]
    },
    {
      "name": "categoryB",
      "map": ["x","y","z"]
    },
    {
      "name": "categoryC",
      "map": ["x","y","z"]
    }
  ]
}

然后可以使用以下模式验证它：

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "categoryMapping": {
      "type": "array",
      "items": {
        "type": "object",
        "required": [
          "name",
          "map"
        ],
        "properties": {
          "name": {
            "type": "string"
          },
          "map": {
            "type": "array",
            "items": {
              "type": "string"
            }
          }
        }
      }
    }
  }
}
