在Logic Apps
在我的档案中
LogicApp.parameters.json
我已经声明了名为MyFirstNewParameter
的额外参数下面的完整文件内容
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"logicAppName": {
"value": "MyFirstLogicAppOne"
},
"servicebus_1_connectionString": {
"value": "Endpoint=sb://notForYouToSee"
},
"MyFirstNewParameter": {
"value": "abc123"
}
}
}
在我的LogicApp.json文件中，我添加了MyFirstNewParameter的“声明”。
中的
“参数”：{}
区域（下面第4行是该部分开始的地方）
我还添加了一个简单的响应，它尝试读取参数值并将其发送回响应中。 （所有事情都命名为“Read_And_Use_Parameter_Value_Simple_Response”）
{

}
],

}
当我发送请求时，我在客户端获得以下内容：
{
"error": {
"code": "NoResponse",
"message": "The server did not received a response from an upstream server. Request tracking id '000000000000000000000'."
}
}
检查门户网站时，会生成以下错误：
InvalidTemplate。无法在第1行和第1232行的“Read_And_Use_Parameter_Value_Simple_Response”输入中处理模板语言表达式：'找不到工作流参数'MyFirstNewParameter'。'。
做什么？
如何在Logic App中“读取”LogicApp.parameters.json中定义的参数？

我也找到了这篇文章：

文章的第一段如下，以防网址将来停止工作（如果移动可能会进行互联网搜索）
逻辑应用参数与ARM参数 我得到的问题是ARM模板参数和Logic App参数之间的差异以及何时应该使用这些参数，这就是我将在本文中尝试解释的内容。 ARM模板的第一个参数与ARM模板一起使用，在将基于ARM的资源部署到Azure时使用ARM模板，而Logic App是通过ARM模板部署的资源。 Logic App的工作流定义语言与ARM模板非常相似，因此在开始时看到差异可能很棘手。

我知道这很令人困惑，但有ARM模板参数和LogicApp参数。您刚刚声明了ARM参数，但错过了LogicApp。然后，您可以将ARM参数传递给LogicApp参数。
试试这个：
