Arm模板(Bicep)：合并appsettings时的循环依赖(list函数)

Question

我正在尝试通过二头肌文件更新应用程序服务的AppSettings。

在我的二头肌模板中执行此操作时：

var currentAppSettings = list('Microsoft.Web/sites/appServiceName/config/appsettings', '2018-11-01')

var newAppSettings = {
  test: 'testValue'
}

var mergedAppSettings = union(currentAppSettings, newAppSettings)

resource appServiceConfig 'Microsoft.Web/sites/config@2018-11-01' = {
  name: 'appServiceName/appSettings'
  properties: mergedAppSettings
}

...I在部署二头肌文件时出现循环依赖错误：

"Deployment template validation failed: 'Circular dependency detected on resource: '/subscriptions/293d7347-b26f-4413-9986-d61717aaff26/resourceGroups/WSAPlayground/providers/Microsoft.Web/sites/playground-fitxp-backend-euw-wa/config/appSettings'. Please see https://aka.ms/arm-template/#resources for usage details.'."

有没有办法在不出现依赖错误的情况下做到这一点？

尝试使用模块。二头肌模块本质上是嵌套部署。在顶层文件(即main)中，提取当前值并将其作为object类型的参数传递给子模块(appsettings)，然后执行合并和更新。提示是将更新部署在不同的模块中，而不是读取当前值。
