如何將CSV字段映射到JSON列表？

Question

我使用的騾子3.8.1，並有這店的開業時間將作爲

Group Name,Group ID,Store ID,Store Name,Mon opening time,Tues opening time,Wed opening time,Thurs opening time,Fri opening time,Sat opening time,Sun opening time,Mon closing time,Tues closing time,Wed closing time,Thurs closing time,Fri closing time,Sat closing time,Sun closing time 
DBLTD,DB1,STORE1,Main Store,9:00,9:00,9:00,9:00,9:00,9:00,9:00,20:00,20:00,20:00,20:00,20:00,20:00,20:00 
DBLTD,DB1,STORE2,NYC Store,9:00,9:00,9:00,9:00,9:00,9:00,9:00,20:00,20:00,20:00,20:00,20:00,20:00,20:00 

我需要使用Dataweave按以下格式它們映射到一個JSON列表csv文件：

{ 
    "groupId": "DB1", 
    "groupName": "DBLTD", 
    "storeId": "STORE1" 
    "storeName": "Main Store", 
    "openingTimes": 
    [ 
     { 
     "day": "mon", 
     "openingTime": "9:00", 
     "closingTime": "20:00" 
     }, 
     { 
     "day": "tues", 
     "openingTime": "9:00", 
     "closingTime": "20:00" 
     } 
     ...etc 
    ] 
} 

我使用來測試這個工作的XML流量：

<?xml version="1.0" encoding="UTF-8"?> 

<mule xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:dw="http://www.mulesoft.org/schema/mule/ee/dw" xmlns:metadata="http://www.mulesoft.org/schema/mule/metadata" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

http://www.mulesoft.org/schema/mule/ee/dw http://www.mulesoft.org/schema/mule/ee/dw/current/dw.xsd"> 
    <flow name="testFlow"> 
     <file:inbound-endpoint path="src\main\resources\input" moveToDirectory="src\main\resources\output" responseTimeout="10000" doc:name="File"/> 
     <dw:transform-message metadata:id="e77b30f7-f9a2-4b97-82a9-23c186dc03cb" doc:name="Transform Message"> 
      <dw:input-payload mimeType="application/csv"/> 
      <dw:set-payload><![CDATA[%dw 1.0 
%output application/json 
--- 
{ 
    GroupID: payload."Group ID", 
    GroupName: payload."Group Name", 
    StoreId: payload."Store ID", 
    StoreName: payload."Store Name" 
}]]></dw:set-payload> 
     </dw:transform-message> 
    </flow> 
</mule> 

有誰知道我怎麼能做到這一點？

嘗試下面的代碼...

%dw 1.0 
%output application/json 
--- 
payload map { 
    GroupID: $."Group ID", 
    GroupName: $."Group Name", 
    StoreId: $."Store ID", 
    StoreName: $."Store Name", 
    openingTimes: [ 
     { 
      'day':'mon', 
      'openingTime':$."Mon opening time", 
      'closingTime': $."Mon closing time" 
     }, 
     { 
      'day':'Tues', 
      'openingTime':$."Tues opening time", 
      'closingTime': $."Tues closing time" 
     }, 
     { 
      'day':'Wed', 
      'openingTime':$."Wed opening time", 
      'closingTime': $."Wed closing time" 
     }, 
     { 
      'day':'Thurs', 
      'openingTime':$."Thurs opening time", 
      'closingTime': $."Thurs closing time" 
     }, 
     { 
      'day':'Fri', 
      'openingTime':$."Fri opening time", 
      'closingTime': $."Fri closing time" 
     }, 
     { 
      'day':'Sat', 
      'openingTime':$."Sat opening time", 
      'closingTime': $."Sat closing time" 
     }, 
     { 
      'day':'Sun', 
      'openingTime':$."Sun opening time", 
      'closingTime': $."Sun closing time" 
     } 

    ]
