Question

我们正在尝试部署一个ARM模板，该模板根据输入参数部署具有 n 事件中心输出的Stream Analytics作业。现在，除了listKeys()属性复制循环函数中的outputs函数之外，我们取得了成功，它获取了每个Event Hub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 - 错误：Code = InvalidTemplate; Message =部署模板验证失败：'模板资源第'129'行的'tailor-router-axgf7t3gtspue'和第'10'列不是有效：模板函数'copyIndex'不在此处地点。该功能只能在具有副本的资源中使用指定。有关使用详情，请参阅https://aka.ms/arm-copy。有关用法，请参阅https://aka.ms/arm-template-expressions 的信息。'。

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]"

它有效。

copyIndex('propertyName')是listKeys()支持的功能吗？如果没有，是否有一种可以达到同样效果的解决方法？

亲切的问候，

感谢您举报并对此给您带来的不便表示歉意。我刚刚和ARM团队谈过，当copyindex在索引标签内部时我们遇到了问题，例如'array [copyindex（）]'。现在应该修复。

让我们知道它是怎么回事。

谢谢，
