数据编织转换数组的元素到字符串

Question

谁能根据输入数据(数组对象的项)为下面的输出结构提供DataWeave逻辑?

输入数据

{
"Items": [{
"name": "Document",
"value": ["Representative", "Manager"]
}, {
"name": "Product",
"value": ["Sales", "Price"]
}]
}

输出数据:

^(+Document:"Representative" +Document:"Manager") ^(+Product:"Sales" +Product:"Price")

Answer 1

解决这个问题的最佳方法是使用map函数和joinBy函数的组合

%dw 2.0
output text/plain
---
payload.Items 
map ((item, index) -> "^(" ++ 
(item.value 
map ((value, index) -> '+$(item.name):"$(value)"') 
joinBy  " ") 
++ ")"
)
joinBy  " "
