Question

我导出了一个资源组，其中包含一些我想在Visual Studio中使用的Logic应用程序，但是无法使用VS中的designer-view打开一个Logic App。

即使您没有以任何方式修改代码，我也会收到此错误：

模板验证失败：'属性'表达式''[concat（'@ equals（toLower（triggerBody（）？[''，parameters（'workflows_Booking_name'），'s']？['Event']）， '创建'）'）]' 模板操作'Condition _-_ Create_or_UpdateBookings'在第'1行'和第'1827列'不是有效的模板语言表达式。'。

逻辑应用程序在门户网站中的外观可以帮助您更好地理解。

Answer 1

正如Szymon Wylezol所说，模板本身似乎有问题。从错误消息中我们知道表达式[concat('@equals(toLower(triggerBody()?['', parameters('workflows_Booking_name'),'s']?['Event']), 'create')')]不正确。有关表达式的更多详细信息，请参阅document。

根据您提供的截图，我们可以在代码视图中获取以下表达式：

"actions": {
    "Condition_-_Create_or_UpdateBookings": {
      "type": "If",
      "expression": "@equals(toLower(triggerBody()?['Bookings']?['Event']), 'create')",
      "actions": {},
      "runAfter": {}
    }
  }

请将VS中的代码视图与Azure门户中的代码视图进行比较。

然后它应该准备好在Visual Studio中查看。有关在Visual Studio中设计，构建和部署Azure Logic应用程序的更多详细信息，请参阅document

演示代码。
