如何在 Mule DataWeave 中过滤 JSON 的数组

Question

我有这样的 JSON :

{
  "dcsId": "1184001100000000517",
  "marketCode": "US",
  "languageCode": "en-US",
  "profile": {
  "base": {
     "username": "arunima27",
     "activeInd": "R",
     "phone": [
       {
          "activeInd": "Y",
          "type": "mobile",
          "primaryInd": "Y",
          "number": "2234566788"
       },
       {
         "activeInd": "N",
         "type": "mobile",
         "primaryInd": "N",
         "number": ""
       }
      ]
    }
  }
 }

从这个输入 JSON 我们需要提取 payload.profile.base.phone.number 其中 payload.profile.base.phone.type == "mobile" 和 payload.profile.base.phone.activeInd == "Y" .实际上，我们需要遍历 JSON 数组 (payload.profile.base.*phone) 并仅获取 phone 处于活动状态且类别/类型为移动的号码。

我们需要如下输出：

{
  "dcsId": "1184001100000000517",
  "marketCode": "US",
  "languageCode": "en-US",
  "username" :  "arunima27", 
  "phoneNumber" : "2234566788"
}

我们在对 "phoneNumber" 输出变量进行此转换时遇到问题。

Answer 1

这已经解决了问题。

{(payload.profile.base.phone 过滤器 ($.activeInd == "Y" and $.primaryInd== "Y"))}.number default ""

Answer 2

从您的预期结果来看，您似乎只需要第一个匹配的数字。这是数据编织正是这样做的：

%dw 1.0
%output application/json
---
{
    dcsid: payload.dcsId,
    markCode: payload.marketCode,
    languageCode: payload.languageCode,
    username: payload.profile.base.username,
    phoneNumber: (payload.profile.base.phone filter ($.activeInd == 'Y' and $.type == 'mobile'))[0].number
}

如果您想要所有匹配的 phone 数字，只需将 [0] 去掉，结果中 phoneNumber 的值将是一个数组（不仅仅是第一个匹配的 phone个数).

Answer 3

在 phone 上使用 filter 和 map 以获得所需的结果。

phoneNumber: {
    (payload.profile.base.phone filter ($.activeInd == "Y" and $.type == "mobile") map {
        number: $.number
    }
)}

输出

"phoneNumber": {
    "number": "2234566788",
 }

Answer 4

 %dw 2.0
 output application/json
 ---
 payload.profile.base.phone filter ((obj, index) -> (obj.activeInd == 'Y' and obj.type  ~= 'mobile'   ))
