Possible solutions (credit to @jerney in the comments)可能的解决方案（在评论中归功于@jerney）

Using index manipulation:使用索引操作：

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input[1..-2]

Using regex:使用正则表达式：

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input replace /^\[|\]$/ with ""

Using simple replacement:使用简单替换：

%dw 1.0
%output application/java

%var input = "[\"HELLO\", \"WORLD\"]"
---
input replace "[" with "" replace "]" with ""
