JSON 模式表单 - 日期格式的最小值或最大值

Question

有没有办法在 JSON 模式表单中设置最小日期？使用 min 不起作用，这是一个示例：

{
  "title": "Date picker",
  "type": "object",
  "properties": {
    "native": {
      "title": "Title",
      "description": "description",
      "type": "object",
      "properties": {
        "date": {
          "type": "string",
          "format": "date",
          "default": "2023-10-26",
          "min": "2023-10-26"
        }
      }
    }
  }
}

Answer 1

min

不是 json 模式关键字。

minimum

是，但它只适用于数字，不适用于字符串。

在当前发布的 JSON Schema 版本中，您可以使用正则表达式实现最小检查的近似值：

description: at or later than 2023-10-26, up to 2099-12-31
type: string
format: date
anyOf:
- pattern: ^2023-10-2[6-9]
- pattern: ^2023-1[12]
- pattern: ^202[4-9]
- pattern: ^20[3-9]
