我只想使用 jsonpath 提取特定值

Question

如何使用 jsonpath 从 Json 中仅提取 id 值，如下所示？

[
      {
      "Name": "Test",
      "Code": "00",
      "options": [      {
         "id": "SS111",
         "roundTrip": false,
         "price": 53900,
         "trains": [         {
            "packageDiscount": 3244,
            "goodsType": "REGULAR"
         }],
         "adults": 1
      }],
      "type": "DOMESTIC_TRAIN"
   },
   {
      "Name": "Test",
      "Code": "00",
      "options": [      {
         "id": "SS222",
         "roundTrip": false,
         "price": 53900,
         "trains": [         {
            "packageDiscount": 3244,
            "goodsType": "REGULAR"
         }],
         "adults": 1
      }],
      "type": "DOMESTIC_TRAIN"
   }
]

我想要的结果如下

SS111,
SS222
