jolt - 检查 jolt 中是否为 null 或为空，并输入另一个存在于输入 JSON 中的值

Question

这是我的输入 JSON：

{
    "AddressBilling": {
        "FirstName": "Some Name",
        "LastName": "Some Name",
        "Address":"some address"
     }
    "AddressShipping": {
        "FirstName": "",
        "LastName": "",
        "Address":""
     }
}

我想保留“AddressBilling”和“AddressShipping”，但名称不同，即“payment_address”和“shipping_address”，为此我为payment_address部分编写了一个规范文件

{
    "operation": "shift",
    "spec": {
      "AddressBilling": {
        "FirstName": "payment_address.firstname",
        "LastName": "payment_address.lastname",
        "Address": "payment_address.address"
      },
       "AddressShipping": {
        "FirstName": "shipping_address.firstname",
        "LastName": "shipping_address.lastname"

      }
    }
}

现在我想要检查“AddressShipping”对象中的“Address”键是否为空，然后我想将“AddressBilling”的“Address”复制到“shipping_address”的“Address”。

Answer 1

可以使用“修改默认值”来做到这一点。如果键不存在或它的值为空，修改默认值只会填写一个值。

规格

[
  {
    "operation": "modify-default-beta",
    "spec": {
      "shipping_address": {
        "address": "@(2,payment_address.address)"
      }
    }
  }
]

输入A，没有收货地址

{
  "payment_address": {
    "address": "some address"
  },
  "shipping_address": {}
}

生成输出 A，其中复制了帐单地址

{
  "payment_address" : {
    "address" : "some address"
  },
  "shipping_address" : {
    "address" : "some address"
  }
}

输入 B，其中有 shipping_address

{
  "payment_address": {
    "address": "some address"
  },
  "shipping_address": {
    "address": 1234
  }
}

生成输出 B，其中送货地址不会被覆盖。

{
  "payment_address" : {
    "address" : "some address"
  },
  "shipping_address" : {
    "address" : 1234
  }
}
