Json JOLT Spec从一组相似命名的键构建数组

尝试构建一个JOLT规范，将类似命名的键放入一个数组中，并去掉前导的6个字符。在下面的示例中，所有以“fd1lk1”开头的键将进入数组“Link1”，以“fd1lk2”开头的键将进入数组“Link2”，以此类推

谢谢你的帮助

源JSON:

{
  "EventName": "WidgetFeedImpression",
  "WidgetName": "_blah_2019.08.17",
  "WidgetID": "5d56ef313db7c300018d9c66",
  "WidgetVariationName": "_blah_2019.08.17",
  "WidgetVariationID": "5b5f524eb1932300014d0928",
  "WidgetTemplate": "blah-six-grid-wth-image",
  "fd1lk1Title": "link 1 title",
  "fd1lk1Image": "link 1 image",
  "fd1lk1TargetURL": "link 1 url",
  "fd1lk1Position": "1",
  "fd1lk1Id": "fd5da8ce0f8701a3000190efbdlk1",
  "fd1lk2Title": "link 2 title",
  "fd1lk2Image": "link 2 image",
  "fd1lk2TargetURL": "link 2 url",
  "fd1lk2Position": "2",
  "fd1lk2Id": "fd5da8ce0f8701a3000190efbdlk2",
  "gtmcb": "1878625665",
  "CreatedAtUtc": "2019-10-24T16:57:01.5274702Z"
}

期望输出：

{
  "EventName": "WidgetFeedImpression",
  "WidgetName": "_blah_2019.08.17",
  "WidgetID": "5d56ef313db7c300018d9c66",
  "WidgetVariationName": "_blah_2019.08.17",
  "WidgetVariationID": "5b5f524eb1932300014d0928",
  "WidgetTemplate": "blah-six-grid-wth-image",
  "Link1" : [ {
    "Title" : "link 1 title",
    "Image" : "link 1 image",
    "TargetURL" : "link 1 url",
    "Position" : "1",
    "Id" : "fd5da8ce0f8701a3000190efbdlk1"
  } ],
  "Link2" : [ {
    "Title" : "link 2 title",
    "Image" : "link 2 image",
    "TargetURL" : "link 2 url",
    "Position" : "2",
    "Id" : "fd5da8ce0f8701a3000190efbdlk2"
  } ],
  "gtmcb": "1878625665",
  "CreatedAtUtc": "2019-10-24T16:57:01.5274702Z"
}

fd1lk*标题

中的

*

被提取并与

&（0,1）

一起使用：
