可变索引值映射Dataweave

Question

这是我必须映射以下项目的输入有效载荷

{
    "externalOrderLineRefs": [
        {
            "sourceSystem": "Shutterfly",
            "identifier": "SFLYOrderLine09876"
        }
    ],
    "externalQuoteLineRefs": [
        {
            "sourceSystem": "Salesforce",
            "identifier": "SFDCQuoteLine123"
        },
        {
            "sourceSystem": "Shutterfly",
            "identifier": "SFLYQuote123456"
        }
    ]
}

映射条件： Quote = externalQuoteLineRefs.identifier WHERE sourceSystem =“ Shutterfly”

Answer 1

这会成功吗？否则，精确的输出将非常有益。

%dw 1.0
%output application/json
---
payload.externalQuoteLineRefs filter $.sourceSystem == "Shutterfly" map {
    quote: $.identifier
}

输出：

[
  {
    "quote": "SFLYQuote123456"
  }
]
