在我的档案中
LogicApp.parameters.json
我已经声明了名为 MyFirstNewParameter 的额外参数
完整的文件内容如下
{
"$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”。
在里面
“参数”： {}
区域（下面的第 4 行是该部分的开始位置）
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。（命名为“Read_And_Use_Parameter_Value_Simple_Response”的所有事物）

当我发送请求时，我在客户端中得到以下信息：
{
"error": {
"code": "NoResponse",
"message": "The server did not received a response from an upstream server. Request tracking id '000000000000000000000'."
}
}
当我检查门户时，会生成以下错误：
无效的模板。无法在“1”行和“1232”列的“Read_And_Use_Parameter_Value_Simple_Response”输入操作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？

附加工作正确的代码
接受的答案表明参数集存在歧义。
这是具有明确名称的更正工作答案。

客户现在收到预期值
**参数值为***ValueIWantToSeeShowUp*****
我还找到了这篇文章：
http://blog.ibiz-solutions.se/integration/logic-apps-parameters-vs-arm-parameters/
文章的第一段如下，以防网址将来停止工作（如果它被移动，可能是互联网搜索）
逻辑应用程序参数与 ARM 参数我得到了一个问题，即 ARM 模板参数和逻辑应用程序参数之间有什么区别，以及何时应该使用这些参数，所以这就是我将在这篇文章中尝试解释的内容。第一个 ARM 模板参数与 ARM 模板一起使用，并且在将基于 ARM 的资源部署到 Azure 时使用 ARM 模板，而逻辑应用程序是通过 ARM 模板部署的资源。Logic App 背后的工作流定义语言与 ARM 模板非常相似，因此一开始很难看出差异。
