从 SharePoint JSON 输出中获取值

Question

我正在从共享点列表中获取以下 JSON 对象。如何在逻辑应用程序的数据操作 (select) 中获取 Company 的值。我做了 item()['Company']?['Value'] 但它不起作用。有什么建议吗？

"body": [
  {
    "Company": {
      "@odata.type": "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
      "Id": 0,
      "Value": "Test1"
    },
    "Date From": "2022-03-30",
    "Date To": "2022-03-31",
    "Title": "Title 1"
  },
  {
    "Company": {
      "@odata.type": "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
      "Id": 2,
      "Value": "Line2"
    },
    "Date From": "2022-03-21",
    "Date To": "2022-03-29",
    "Title": "Title 2"
  }
]
}

我正在获取共享点列表，然后使用数据操作 (select) 获取 JSON 作为输出。

我需要以下格式的 JSON，以便我可以将其传递给存储过程并插入到 Azure SQL 数据库中。我在列表中还有另外 12 个项目。

         [
          {
            "Company": "Test1",
            "Date From": "2022-03-30",
            "Date To": "2022-03-31",
            "Title": "Title 1"
          },
          {
            "Company": "Line2",
            "Date From": "2022-03-21",
            "Date To": "2022-03-29",
            "Title": "Title 2"
          }
        ]

而不是select，您可以设置一个变量。我们都是不同的，但这对我来说更有意义。

你的表达方式大同小异，我用...

item()['Company']['Value']

只需确保在 For each ...

之外和之前初始化变量

这是数组中第一项的结果...

要编译一个完整的 JSON 对象并将其添加到一个数组中，再次简单地使用一个变量并根据需要指定值。

首先，在 For each ...

之外初始化数组

... 然后在 For each 中，在每个循环中向数组变量添加一个对象（确保在需要的地方包括表达式周围的引号）...

你只需要编译JSON。最终结果将如下所示...

这是完整的 JSON ...

[
  {
    "Company": "Line2",
    "Date From": "2022-03-21",
    "Date To": "2022-03-29",
    "Title": "Title 2"
  },
  {
    "Company": "Test1",
    "Date From": "2022-03-30",
    "Date To": "2022-03-31",
    "Title": "Title 1"
  }
]

此外，您会注意到我的列表以不同的顺序出现，那是因为 For each 并行运行，如果您需要避免这种情况，请更改设置以使其在单个线程中运行...

这是 LogicApp 的 JSON 定义，您可以将其加载到您的租户中并使用它进行测试...
