ServiceBus的Azure ARM模板：无法引用自身

问题描述 投票：1回答：1

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使管理主题和订阅变得容易。为了实现这一点，脚本使用数组变量。

这一切都很好，但每当我尝试为两个不同的主题使用相同的订阅名称时，我就会看到一个问题。现在，我了解订阅只能映射到一个主题。该脚本尝试通过将订阅名称加入主题来解释该问题。

我还应该注意，Azure UI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控制台设置此方案，然后导出ARM。

我已经在这个脚本上打了几十次，但我没有看到原因。希望新的眼睛会有所帮助。

这是脚本：

执行时：

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

它返回：

该问题是由'sbSubscriptions'数组（mysubB / mytopic3）中的第三个条目引起的。这是在'资源'下面的第三个对象中处理的。

如果有人能看到我的疏忽，我们将不胜感激。

PS。如果有人知道如何让Azure工具在扩展“复制”节点和功能（resourceId，concat）之后输出模板json，那么这也是有用的。
