Azure ARM 模板 : DocumentDB primaryMasterKey as OUTPUT

Question

在 Azure ARM 模板中，我在尝试在 OUTPUT 部分中提取在 RESOURCES 部分中创建的 DocumentDB 的“primaryMasterKey”时遇到一些问题。

部署报告此错误:

The template output 'documentDbPrimaryMasterKey' is not valid: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.. (Code: DeploymentOutputEvaluationFailed)

该输出的定义是:

"documentDbPrimaryMasterKey": {
     "type": "object",
     "value": "[listKeys(resourceId('Microsoft.DocumentDB/databaseAccounts', variables('documentDb').name), providers('Microsoft.DocumentDB','databaseAccounts').apiVersions[0]).primaryMasterKey]"
  }

这是我的模板 https://github.com/toto-castaldi/azure-templates/blob/master/documentdb/template.json

这很奇怪，因为“listKeys”的结果是一个正确的 JSON，例如

{"primaryMasterKey":"XXXX","secondaryMasterKey":"XXX","primaryReadonlyMasterKey":"XXX","secondaryReadonlyMasterKey":"XXXX}

好吧，你显然想要一个字符串，而不是一个对象:)

"documentDbPrimaryMasterKey": {
    "type": "String", # <<< STRING
    "value": "[listKeys(resourceId('Microsoft.DocumentDB/databaseAccounts', variables('documentDb').name), providers('Microsoft.DocumentDB','databaseAccounts').apiVersions[0]).primaryMasterKey]"
}
