如何将数组动态拆分为多个字符串

Question

输入：{   “ID”： [     1，2，3，4，5，6，7，8，9，10   ] }

输出：{ “ID”： [ “ 1,2,3”， “ 4,5,6”， “ 7,8,9”， “ 10” ] }

%dw 2.0
output application/json
---
"id": vars.pd.*id joinBy ","

Answer 1

您可以在divideBy模块中使用dw::core::Arrays功能。

%dw 2.0
import * from dw::core::Arrays
output application/json
---
"id": payload.id divideBy 3 map ((v) -> v joinBy ",")
