您应该首先对整个阵列应用过滤器，然后执行转换的其余部分：

%dw 2.0
output application/json skipNullOn="everywhere"
fun toDate(v) = (v as String{format:'yyyy-MM-dd'} as Date) default null
var status = 'SUBSCRIBED'
var accountId = 'a-t-1000-5001-0687-0024'
---
if (payload is Array)
  flatten(payload filter ($.CloudAccountDetail.CloudAccountId == accountId and $.CloudAccountDetail.Status == status) map(item, value) -> 
flatten ( [
                item.NamedSubscriptions map {
                    key: $.SubscriptionId,
                    expiryDate: toDate($.ExpiryDate)
                    //nextPaymentDate: toDate($.NextPaymentDueDate)
                } 
                , 
                item.UnnamedSubscriptions map {
                    key: $.SubscriptionId,
                    expiryDate: toDate($.ExpiryDate),
                    cloudPublicName: item.CloudAccountDetail.CloudAccountPublicName,
                    cloudAccountId: $.EskoCloudAccount
                }
            ] ))
else []

更干净的例子。尝试使用
函数
填充值，而不是使用展平

例如：

%dw 2.0
var accountStatus=["SUBSCRIBED"]
var accountId=["a-t-1000-5001-0687-0024"]
fun getData(items, account, isUnnamedSubscriptions) = 
    (items default []) map {
        "key": $.SubscriptionId,
        "expiryDate": $.ExpiryDate as Date,
        ("cloudPublicName": account.CloudAccountPublicName) if (isUnnamedSubscriptions),
        ("cloudAccountId": account.CloudAccountId) if (isUnnamedSubscriptions)
    }

output application/json
---

(payload[?((accountId contains $.CloudAccountDetail.CloudAccountId) 
    and (accountStatus contains $.CloudAccountDetail.Status) )] map (
        getData($.NamedSubscriptions, $.CloudAccountDetail, false)
        ++
       getData($.UnnamedSubscriptions, $.CloudAccountDetail, true)
) flatMap () -> $) default []

payload[?( (isValidFilter($.CloudAccountDetail.CloudAccountId, 
  $.CloudAccountDetail.Status)) )] map ...

accountId
变量是一个数组，您也可以将其替换为字符串，类似于第
2行和第
3行中的
status

如果要筛选多个accountId，只需在
accountId
中添加另一个字符串，与
状态相同

如果要在CloudAccountDetail.Status为Null且CloudAccountDetail.CloudAccountId为Null时排除筛选器


您可以创建一个返回布尔值的函数。函数应该是这样的


fun isValidFilter(id, stat) = 
    if ( id !=null and stat != null) 
       ((accountId contains id) and (accountStatus contains stat))
    else (true)


然后将值传递给函数
isValidFilter

例如：


%dw 2.0
var accountStatus=["SUBSCRIBED"]
var accountId=["a-t-1000-5001-0687-0024"]
fun getData(items, account, isUnnamedSubscriptions) = 
    (items default []) map {
        "key": $.SubscriptionId,
        "expiryDate": $.ExpiryDate as Date,
        ("cloudPublicName": account.CloudAccountPublicName) if (isUnnamedSubscriptions),
        ("cloudAccountId": account.CloudAccountId) if (isUnnamedSubscriptions)
    }

output application/json
---

(payload[?((accountId contains $.CloudAccountDetail.CloudAccountId) 
    and (accountStatus contains $.CloudAccountDetail.Status) )] map (
        getData($.NamedSubscriptions, $.CloudAccountDetail, false)
        ++
       getData($.UnnamedSubscriptions, $.CloudAccountDetail, true)
) flatMap () -> $) default []



payload[?( (isValidFilter($.CloudAccountDetail.CloudAccountId, 
  $.CloudAccountDetail.Status)) )] map ...



谢谢你，奥利弗。但在这里，我对过滤器的有条件使用感兴趣。我只需要过滤器，并且仅当status和accountId有任何值时才需要过滤器。如果它们为空，则我不需要过滤器。”“使用”可以在这里使用，但我正在努力使用它。我明白了。你能提供一个输入样本和预期输出吗？谢谢。@user12445682请确认我在答案中发布的结果是否是您期望的结果。如果没有，请解释错误，以便我可以改进答案。谢谢你，谢谢你的回答，雷。但我的问题是，如果accountStatus=null和accountId=null（表示值不存在），那么我不需要基于这两个值进行过滤。非常感谢您的回答。但我的问题是，如果accountStatus=null和accountId=null（意味着值不存在），那么我不需要基于这两个值进行过滤。您可以使用默认值。示例：可以创建一个返回布尔值的函数。该函数应该像下面这样有趣的isValidFilter（id，stat）=if（id！=null和stat！=null）（（accountId包含id）和（accountStatus包含stat））else（true），有效负载的公式是：有效负载[？（（isValidFilter（$.CloudAccountDetail.CloudAccountId，$.CloudAccountDetail.Status））]map```
