我需要的输出如下。我无法创建分隔数组中的元素。

解决方法
由于转换数据的规则尚不明确，我做了自己的尝试，似乎产生了预期的结果：
%dw 2.0
output application/json
---
flatten (
payload map (item,order) -> (
flatten ( [
item.NamedSubscriptions map {
key: $.SubscriptionId,expiryDate: $.ExpiryDate as Date
},item.UnnamedSubscriptions map {
key: $.SubscriptionId,expiryDate: $.ExpiryDate as Date,cloudPublicName: item.CloudAccountDetail.CloudAccountPublicName,cloudAccountId: item.CloudAccountDetail.CloudAccountId
}
] )
)
)
使用 flatten 将删除数组的额外级别。
示例：
%dw 2.0
fun getSubscription(items) =
(items default []) map {
"key": $.SubscriptionId,"expiryDate": $.ExpiryDate as Date
}
fun getUnsubscriptions(items,id,name) =
(items default []) map {
"key": $.SubscriptionId,"expiryDate": $.ExpiryDate as Date,"cloudPublicName": name,"cloudAccountId": id
}
output application/json
---
flatten (payload map (getSubscription($.NamedSubscriptions) ++
getUnsubscriptions($.UnnamedSubscriptions,$.CloudAccountDetail.CloudAccountId,$.CloudAccountDetail.CloudAccountPublicName)))
使用功能 fun 将使其更整洁和可读性。
使用 flatMap 并重复使用一个函数来提取Named和UnnamedS订阅。
%dw 2.0
fun getData(items,account,isUnnamedSubscriptions) =
(items default []) map {
"key": $.SubscriptionId,("cloudPublicName": account.CloudAccountPublicName) if (isUnnamedSubscriptions),("cloudAccountId": account.CloudAccountId) if (isUnnamedSubscriptions)
}
output application/json
---
payload map (
getData($.NamedSubscriptions,$.CloudAccountDetail,false)
++
getData($.UnnamedSubscriptions,true)
) flatMap () -> $
