Dataweave 数组差异

Question

我有 2 个数组。arr1 将是一个超集，而 arr2 将是一个子集，并且 arr2 的大小将始终小于 arr1。

我想找出 arr1 中哪些值不在 arr2 中。

例如

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

预期结果应该是 ["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
