mule - mule 4中JSON数据的转换

Question

我有一个要求，我必须将 JSON 数据从一种格式转换为另一种格式。我必须获取 JSON 数组的相应值，并使它们成为键值对。

以下是所需的详细信息:

输入:

"Headers": {
    "Header": [
      {
        "Key": "SellerOrganization",
        "Value": "XYZ"
      },
      {
        "Key": "SellerType",
        "Value": "B2C"
      },
      {
        "Key": "Region",
        "Value": "SOUTH"
      },
      {
        "Key": "OrderType",
        "Value": "RETURN"
      },
      {
        "Key": "InvoiceType",
        "Value": ""
      },
      {
        "Key": "EventType",
        "Value": "Created"
      },
      {
        "Key": "EntryType",
        "Value": "Call Center"
      }
    ]
  }

预期输出:

{
    SellerOrganization:XYZ,
    SellerType: B2C,
    Region:SOUTH,
    OrderType:RETURN,
    InvoiceType:"",
    EventType:Created,
    EntryType:Call Center
}

您可以使用 dynamic object它基本上会做你想做的事。

%dw 2.0
output application/json

{
    (payload.Headers.Header map ((item, index) -> {
        (item.Key): item.Value
    })
    )
}
