Azure 订阅上的 Azure EventGrid - 确定哪个标签已更改

Question

我正在尝试为 Azure 订阅设置 Azure EventGrid，以便在资源的某个标签发生更改时收到通知。

这就是我创建 EventGrid 订阅的方式:

$includedEventTypes  = , 'Microsoft.Resources.ResourceWriteSuccess'
New-AzEventGridSubscription `
  -EventSubscriptionName mySubscriptionName `
  -ResourceGroupName myResourceGroup `
  -Endpoint myEndpoint `
  -IncludedEventType $includedEventTypes

现在，如果我更改 Azure Web 应用程序上的标签，我会收到以下事件:

{
  "subject": "/subscriptions/mySubId/resourceGroups/eventgrid/providers/Microsoft.Web/sites/wd-eventgrid-viewer",
  "eventType": "Microsoft.Resources.ResourceWriteSuccess",
  "eventTime": "2019-06-03T08:50:47.7469859Z",
  "id": "f193df79-6755-42c7-b663-91bc373a80e5",
  "data": {
    "authorization": {
      "scope": "/subscriptions/mySubId/resourceGroups/eventgrid/providers/Microsoft.Web/sites/wd-eventgrid-viewer",
      "action": "Microsoft.Web/sites/write",
      "evidence": {
        "role": "Subscription Admin"
      }
    },
    "claims": {
     ....
    },
    "correlationId": "9a1bb49f-9f39-4e98-918c-dfe0655b895a",
    "httpRequest": {
      "clientRequestId": "8bf9bfdb-6e65-4c55-84f2-3f4e05b340d0",
      "clientIpAddress": "......",
      "method": "PATCH",
      "url": "https://management.azure.com/subscriptions/mySubId/resourceGroups/eventgrid/providers/Microsoft.Web/sites/wd-eventgrid-viewer?api-version=2015-08-01"
    },
    "resourceProvider": "Microsoft.Web",
    "resourceUri": "/subscriptions/mySubId/resourceGroups/eventgrid/providers/Microsoft.Web/sites/wd-eventgrid-viewer",
    "operationName": "Microsoft.Web/sites/write",
    "status": "Succeeded",
    "subscriptionId": "mySubId",
    "tenantId": "...."
  },
  "dataVersion": "2",
  "metadataVersion": "1",
  "topic": "/subscriptions/mySubId"
}

不幸的是，我没有看到标签已更改，也没有看到哪个标签已更改。有没有办法接收资源的哪个标签已更改或者我是否必须在事件发生后手动查询标签？

Answer 1

Azure Subscription Events如记录的那样，针对资源操作、删除或写入发出。

您只会获得用于获取更改的资源详细信息。

正如您所想，您必须将这些详细信息与 Resources API 一起使用。获取标签。

更新: get resource changes 有一个新的 API您可以使用它来检测对资源所做的确切更改。 请注意此功能目前处于公共(public)预览版。
