Azure ARM 模板部署。未提供模板参数的值

Question

我正在扩展其中一个 Azure 快速入门模板来部署带有 VNET 集成的 Azure Web 应用程序。已经创建了 RG、网络组件和应用服务计划（使用 powershell）。我正在使用 ARM 模板来部署 Web 应用程序。但我在执行部署时遇到以下错误。

我使用 JSON Lint 来验证 JSON 并且看起来没问题。错误代码告诉我参数文件的语法存在问题，但我无法查明它。我尝试了很多方法来调试它，但无法修复它。

错误：

Answer 1

我删除了旧文件并重新创建了一个具有相同内容的新 JSON 文件。它现在正在工作。我不知道是什么导致旧文件出现问题..

Answer 2

问题似乎是您使用的 powershell cmdlet 参数而不是您的模板/参数的结果。请尝试以下操作：

使用TemplateParameterFile 而不是TemplateParameterUri

使用TemplateFile 代替TemplateUri

将文件参数用于非基于 uri 的 arm 部署，这应该可以解决您的问题。 https://docs.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-4.5.0

Answer 3

我认为您的问题是因为您提供了对现有资源的依赖项。删除"serverFarmId": "[parameters('appServicePlanResourceID')]"。

另外一个需要修复的是你在参数文件中的resourceId的硬编码值。
