Azure 逻辑应用程序从单独收到的 xml 创建 JSON 数组

Question

我是 Azure 新手，必须根据逻辑应用收到的单独 XML 消息创建 JSON 数组。逻辑应用请求数据并接收 XML 格式的响应。我提出了一种将消息保存在 Azure 存储中然后通过 Azure 函数创建 JSON 数组的方法。这种方法会影响性能吗？有什么想法吗？

提前致谢

Answer 1

有两种方法可以完全依赖逻辑应用程序而不涉及 Azure 功能

将此作为样本 xml

<?xml version="1.0"?>
<PurchaseOrder PurchaseOrderNumber="99503" OrderDate="1999-10-20">
  <Address Type="Shipping">
    <Name>Adam Murphy</Name>
    <Street>123 Maple Street</Street>
    <City>Mill Valley</City>
    <State>CA</State>
    <Zip>10999</Zip>
    <Country>Ireland</Country>
  </Address>
  <Address Type="Billing">
    <Name>Tai Yee</Name>
    <Street>8 Oak Avenue</Street>
    <City>Old Town</City>
    <State>PA</State>
    <Zip>95819</Zip>
    <Country>Ireland</Country>
  </Address>
  <DeliveryNotes />
</PurchaseOrder>

方式一

您可以使用 json(xml(triggerBody())) 直接将 xml 转换为 json 这是供您参考的逻辑应用程序 -

输出

如果您想要自定义 json，则可以使用 Parse_Json 和 Compose 连接器创建一个。

这里我只是将 Compose 连接器的输出带到 Parse_Json 以解析结果 Json 以获得自定义 JSON 脚本。下面是我正在尝试创建的 Json。

{
  "PurchaseOrder": {
    "OrderNumber": "@{body('Parse_JSON')?['PurchaseOrder']?['@PurchaseOrderNumber']}",
    "PurchaseDate": "@{body('Parse_JSON')?['PurchaseOrder']?['@OrderDate']}",
    "Location": [
      {
        "Name": "@{items('For_each')?['Name']}",
        "Address": "@{items('For_each')?['Street']},@{items('For_each')?['City']},@{items('For_each')?['State']},@{items('For_each')?['Country']},@{items('For_each')?['Zip']}"
      }
    ]
  }
}

输出

这是我的逻辑应用程序的代码视图。您可以直接使用它在您的逻辑应用程序中获取准确的工作流程。

您可以使用液态模板，以便使用 Transform XML to JSON 连接器将 xml 转换为 json。更多信息可以参考 and .
