Dataweave数组差异

Question

我有两个数组。arr1将是一个超集，arr2将是一个子集，arr2的大小将始终小于arr1。

我想找出哪些不在arr2中的值在arr1中。

例如：

arr1 = [
  "07d65369-78eb-4afb-aba8-710ac146b93f",
  "15d65369-25eb-9u4b-6t7m-820ac145t8w1"
]
arr2 = [
  "07d65369-78eb-4afb-aba8-710ac146b93f"
]

预期结果为15d65369-25eb-9u4b-6t7m-820ac145t8w1

Answer 1

像这样的东西也许..。

%dw 2.0
output application/json
var arr1 = [
  "07d65369-78eb-4afb-aba8-710ac146b93f",
  "15d65369-25eb-9u4b-6t7m-820ac145t8w1",
  "435rt3e-25eb-gh56-6t7m-njhyuiigt6565"
]
var arr2 = [
  "07d65369-78eb-4afb-aba8-710ac146b93f",
  "435rt3e-25eb-gh56-6t7m-njhyuiigt6565"
]
---
arr1 -- arr2
