listKeys() 中的 copyIndex()

Question

我们正在尝试部署一个 ARM 模板，该模板使用 n 事件中心输出部署流分析作业，具体取决于输入参数。现在，除了 outputs 属性复制循环函数中的 listKeys() 函数外，我们都取得了成功，该函数获取每个事件中心的主键：

"sharedAccessPolicyKey": "[listKeys(resourceId('Microsoft.EventHub/namespaces/eventhubs/authorizationRules', variables('clientEventHubNamespace'), parameters('clients')[copyIndex('outputs')].id, variables('clientEventHubClientSharedAccessName')), '2015-08-01').primaryKey]"

我们收到错误：

17:44:31 - Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The template resource 'tailor-router-axgf7t3gtspue' at line '129' and column '10' is not valid: The template function 'copyIndex' is not expected at this location. The function can only be used in a resource with copy specified. Please see https://aka.ms/arm-copy for usage details.. Please see https://aka.ms/arm-template-expressions for usage details.'.

但是，如果我们将其更改为特定索引：

"sharedAccessPolicyKey": "[listKeys(resourceId('Microsoft.EventHub/namespaces/eventhubs/authorizationRules', variables('clientEventHubNamespace'), parameters('clients')[0].id, variables('clientEventHubClientSharedAccessName')), '2015-08-01').primaryKey]"

有效。

listKeys() 中的 copyIndex('propertyName') 是受支持的函数吗？如果没有，是否有可以达到相同效果的解决方法？

亲切的问候，

感谢您报告此事，对于给您带来的不便，我们深表歉意。我刚和 ARM 团队谈过，当 copyindex 位于索引标签内时我们遇到了问题，例如 'array[copyindex()]'。现在应该修复了。

让我们知道进展如何。

谢谢，
