ServiceBus 的 Azure ARM 模板：无法引用自身

Question

我编写了一个 ARM 模板来编写 ServiceBus 的部署和配置脚本。该脚本的目标之一是简化主题和订阅的管理。为了实现这一点，脚本使用数组变量。

一切正常，但每当我尝试对两个不同的主题使用相同的订阅名称时，我都会遇到问题。现在，我了解到订阅只能映射到单个主题。该脚本尝试通过将订阅名称加入主题来解决这个问题。

我还应注意，Azure UI 将允许您在两个主题下使用相同的订阅名称。此脚本源自通过 azure 控制台设置此场景然后导出 ARM。

我已经检查过这个脚本几十次了，但我没有看到原因。希望新的眼睛能有所帮助。

这是脚本：

执行时：

New-AzureRmResourceGroupDeployment -ResourceGroupName {xxx} -TemplateFile arm.servicebus.example.json

它returns:

问题是由 'sbSubscriptions' 数组中的第三个条目 (mysubB/mytopic3) 引起的。这正在 'resources'.

下面的第三个对象中处理

如果有人能看到我的疏漏，将不胜感激。

PS。如果有人知道如何让 Azure 工具在扩展 "copy" 节点和函数（resourceId、concat）后输出模板 json，那也会有帮助。
