在嵌套ARM模板中使用resourceId函数时出错

Question

我正在尝试在嵌套模板中部署函数应用程序(应用程序服务)、应用程序服务计划和Azure存储帐户，但在尝试部署时收到错误消息：

Status Message: The Resource 'Microsoft.Storage/storageAccounts/saaccountname389' under resource group '<null>' was not found. For more details please go to https://aka.ms/ARMResourceNotFoundFix (Code:ResourceNotFound)

导致模板失败的部分在函数app的属性中的appSettings中，它试图列出存储帐户密钥。我见过的所有示例模板(包括Azure中的导出模板选项)，请按照下面的代码使用listKeys(resourceId('Microsoft.Storage/storageAccounts'，‘storageaccountnamehere’执行此操作：

"appSettings": [
                                        {
                                            "name": "AzureWebJobsStorage",
                                            "value": "[concat('DefaultEndpointsProtocol=https;AccountName=',variables('Resources').FunctionStorageAccName,';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', variables('Resources').FunctionStorageAccName), '2019-06-01').keys[0].value,';EndpointSuffix=','core.windows.net')]"
                                        },
                                        {
                                            "name": "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING",
                                            "value": "[concat('DefaultEndpointsProtocol=https;AccountName=',variables('Resources').FunctionStorageAccName,';AccountKey=',listKeys(resourceId('Microsoft.Storage/storageAccounts', variables('Resources').FunctionStorageAccName), '2019-06-01').keys[0].value,';EndpointSuffix=','core.windows.net')]"
                                        }

我看到我的模板和我看到的其他模板之间的唯一区别是，我的模板是嵌套的，我想我可能没有在嵌套模板中正确使用resourceId，但是我真的无法确定我需要做什么不同的事情，并且ms文档没有指出更多的清晰度：https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/scope-functions?tabs=azure-powershell。

我尝试了resourceId函数的许多变体，比如包括资源组名、资源组名称和订阅ID -所有这些都会返回略微不同的错误。

完整的嵌套模板如下：

将嵌套模板的作用域放在与父模板不同的资源组中。看起来您的存储帐户位于不同的RG中，而不是您要部署的功能。默认情况下，resourceId函数假定资源与您部署模板的RG相同(在您的示例中是嵌套的RG)。

您需要在resourceId函数中指定存储帐户所在的资源组的名称，或者将存储帐户密钥作为securestring参数传递到嵌套模板中。

顺便说一句，你有没有考虑过在IaaC上使用Azure Bicep来代替ARM？
