Question

输入:

{
  "creatives": [
    {
      "link_promo": [
        "https://facebook.com/123",
        "https://facebook.com/456"
      ]
    },
    {
      "link_promo": [
        "https://facebook.com/789",
        "https://facebook.com/101112"
      ]
    },
    {
      "link_promo": [
        "https://facebook.com/121314",
        "https://facebook.com/141516"
      ]
    }
  ]
}

规格:

[
  {
    "operation": "shift",
    "spec": {
      "creatives": {
        "*": {
          "link_promo": "promo_links[]"
        }
      }
    }
  }
]

输出:

{
  "promo_links": [
    [
      "https://facebook.com/123",
      "https://facebook.com/456"
    ],
    [
      "https://facebook.com/789",
      "https://facebook.com/101112"
    ],
    [
      "https://facebook.com/121314",
      "https://facebook.com/141516"
    ]
  ]
}

期望的输出：

{
  "promo_links": [
    "https://facebook.com/123",
    "https://facebook.com/456",
    "https://facebook.com/789",
    "https://facebook.com/101112",
    "https://facebook.com/121314",
    "https://facebook.com/141516"
  ]
}

大家好，我需要将嵌套列表展平为数组，如上所述。大家好，我需要将嵌套列表展平为数组，如上所述。有什么想法可以修改我的 jolt 规范以实现该输出吗？

Answer 1

替换零件再嵌套一步

"link_promo": "promo_links[]" 与 "link_promo": { "*": "promo_links" }

为了到达 JSON 的最里面，如下面的规范

[
  {
    "operation": "shift",
    "spec": {
      "creatives": {
        "*": {
          "link_promo": {
            "*": "promo_links"
          }
        }
      }
    }
  }
]
