在逻辑应用程序中将数组转换为字符串变量

Question

使用 Logic App 将数组转换为字符串变量（同时保留所有换行符）的最快方法是什么？下面是我的定义，它读取每个数组并附加到一个字符串变量，工作正常但不是最有效的。我的想法是，然后我可以从最终输出创建一个 BLOB，而无需 ["..."]

基本上我正在寻找一种转换数组的方法

[
  "Header1,Header2",
  "Data1,Data2",
  "Data3,Data4"
]

到一个字符串

Header1,Header2
Data1,Data2
Data3,Data4

Answer 1

其中一个解决方法是使用 Join 连接器，它连接数组中的每个项目。这是我的逻辑应用程序的屏幕截图
