如何将 foreach 循环的结果连接或合并到一个数组中？

Question

我有一个 for each 操作，它接收一个 JSON 数组并添加一个 Item:Key 对。

for each 的输入如下所示：

[
  {
    "memberName": "G-TEL FOR ENBRIDGE GAS (LEGACY UNION GAS) (ENOW01)",
    "stationCode": "ENOW01",
    "initialStatus": "Notification sent"
  },
  {
    "memberName": "G-TEL FOR CITY OF BRANTFORD - STREETLIGHTS (BRASL01)",
    "stationCode": "BRASL01",
    "initialStatus": "Notification sent"
  },
  {
    "memberName": "G-TEL FOR BRANTFORD POWER (LOCAL HYDRO) (BRAP01)",
    "stationCode": "BRAP01",
    "initialStatus": "Notification sent"
  },
  {
    "memberName": "G-TEL FOR CITY OF BRANTFORD - SEWER/WATER/STORM (BRAS01)",
    "stationCode": "BRAS01",
    "initialStatus": "Cleared"
  },
  {
    "memberName": "G-TEL FOR BELL CANADA (BCOW01)",
    "stationCode": "BCOW01",
    "initialStatus": "Notification sent"
  }
]

我在 compose 中使用它从变量中插入一个值：array(union(items('For_each_3'),outputs('Compose_8'))) 并得到这个结果：

[
  {
    "memberName": "G-TEL FOR ENBRIDGE GAS (LEGACY UNION GAS) (ENOW01)",
    "stationCode": "ENOW01",
    "initialStatus": "Notification sent",
    "LocateNumber": "2022054487"
  }
]

相同的值被插入到每个对象中。现在我需要合并结果，以便在 Excel 电子表格中添加行。

我边走边想，我试图使用我在别处找到的这个表达式将结果组合回一个数组：join(items('For_each_3'),',')。但是我得到一个错误，Join 期望第一个参数是一个数组。我认为每个结果已经是一个数组。我一直在寻找答案，但找不到。

正如我提到的，我希望输出到 excel 电子表格，所以如果有更好的方法来做到这一点，我很乐意听到它，但我仍然想知道如何加入结果也只是为了我自己的知识。谢谢。

Answer 1

这是解决方法之一。因为你想将数据保存到你的 excel 我已经直接使用 excel 作为业务连接器（你可以根据你的要求使用任何 excel 相关的连接器）。

这是我的逻辑应用程序

输出：-

这是我生成的 excel 文件

Answer 2

如果我没理解错的话，你想在你的原始数组中的每个项目中添加相同的“LocateNumber”，如果是这样的话，我设法得到了一些有用的东西但是，它确实需要特定的设置才能正常工作。

我创建了一个新数组对象，然后将每个 updated/new 项添加到该新数组中。 Excel 方面，我还没有解决，但这回答了关于你遇到的问题的直接问题。

向您展示的最简单方法是为您提供 JSON 定义，以便您可以在自己的租户中重新创建它。

流程的基础是...

创建存储现有数组、正在处理的数组项、new/updated 项和新数组的变量。
处理数组中的每一项，将当前项存储在一个新变量中（已为 debugging/visibility 包含此项），然后用新的属性更新该项，最后将其添加到新数组。

该公式中的表达式（虽然在附加的定义中找到）看起来像这样...

addProperty(variables('Array Item Object'), 'LocateNumber', '2022054487')

关键设置

For Each 必须将并发切换为 1。它不喜欢打开它，它在重复项目的新数组中不断出现错误输出。

转到操作上的 Settings 并使其看起来像下面这样。

流程中的最后一步只是一个新变量，它有助于可视化流程运行后的输出。

[
  {
    "initialStatus": "Notification sent",
    "memberName": "G-TEL FOR ENBRIDGE GAS (LEGACY UNION GAS) (ENOW01)",
    "stationCode": "ENOW01",
    "LocateNumber": "2022054487"
  },
  {
    "initialStatus": "Notification sent",
    "memberName": "G-TEL FOR CITY OF BRANTFORD - STREETLIGHTS (BRASL01)",
    "stationCode": "BRASL01",

如果您认为该解决方案可以接受，我相信您可以将其改编成您自己的流程。
