JSON-pointers

rules

• 以 "/" 开头的为绝对路径，相对整个 json 元数据，否则为相对路径，以当前校验的字段为基准
• "0": 当前 pointer 的 value
• "0#": 当前 pointer 的 key
• "1": 上一级 pointer 的 value
• "1#": 上一级 pointer 的 key
• "2": 上两级 pointer 的 value
• "2#": 上两级 pointer 的 key
  ...以此类推

example

// json data
const json = {
  "isSunday": false,
  "user": {
    "name": "gary",
    "age": 25,
    "courses": [
      {
        "name": "physical",
        "score": 95,
      },
      {
        "name": "chemistry",
        "score": 90,
      }
    ],
  },
  "fruits": ["apple", "bananer"]
}
