如何在 Azure Logic Apps 的 Slack Webhook 中显示数组？

Question

我有 LogicApps。它在 HTTP 请求中接收属性 ListOfNames 数组。

我很难在 Slack webhook 中正确显示。如何格式化正文？

Slack 中显示的当前消息：名单： ["Name1\n","Name2\n","Name3\n"]

slack 中的目标消息：名单：姓名1 名字2 名字3

我试过拆分：

代码：没有错误，但未排列消息中正确列出的项目：

Answer 1

您可以在 webhook 连接器之前添加一个组合连接器，并使用提供正确格式的拆分功能，然后将 compose 连接器的输出添加到您的 webhook 连接器。

这里有截图供大家参考：

注意： 确保将来自 compose 连接器的拆分中的表达式修改为 split(triggerBody()?['ListOfFiles'],'\ n') 到 split(triggerBody()?['ListOfFiles'],'\n') 因为当我们为此编写表达式时，它首先将 '\n' 作为字符串然后添加另一个 ''.

下面是compose连接器中的拆分表达式：

split(triggerBody()?['ListOfFiles'],'

')

更新答案

当我们检索数组并将其传递给文本正文时，它正在向其中添加额外的字符。我们创建了一个新的逻辑应用程序，并将我们正在检索的每个项目添加到一个变量中，最后将该变量添加到 Webhook 主体中。
