事件网格将事件过滤到订阅中的所有Azure函数

Question

我正在尝试过滤事件网格中的事件，使其仅在我的订阅中的Azure功能更改时触发（例如配置更改、代码更新或创建/删除新功能）。

我使用的 PowerShell 脚本如下所示：

# Provide an endpoint for handling the events. Must be formatted "https://your-endpoint-URL"
$myEndpoint = "https://myendpoint-function.azurewebsites.net"
$subscriptionId = "abcde-34df-4493-9477-notrealid980"

$eventSubscriptionName = "FunctionConfigChanges"

# Select the Azure subscription you want to subscribe to. You need this command only if the 
# current subscription is not the one you wish to subscribe to.
Set-AzContext -Subscription $subscriptionId

$includedEventTypes = "Microsoft.Resources.ResourceActionSuccess", "Microsoft.Resources.ResourceDeleteSuccess", "Microsoft.Resources.ResourceWriteSuccess"
$AdvancedFilters = @{operator="StringContains"; key="Subject"; Values=@("providers/Microsoft.Web/sites")}
New-AzEventGridSubscription -Endpoint $myEndpoint -EventSubscriptionName $eventSubscriptionName -IncludedEventType $includedEventTypes -AdvancedFilter $AdvancedFilters

这将过滤到所有功能和网站（请检查＜code＞和$AdvancedFilters）。是否有任何方法可以将事件仅过滤到Azure函数？欢迎使用Azure CLI、portal、Powershell或.net sdk中的任何解决方案帮助。

对于您的要求，可以使用以下属性，请注意操作名称和操作位于数据对象中：

>

创建函数：

"eventType":"Microsoft.Resources.ResourceWriteSuccess"
"operationName":"Microsoft.Web/sites/functions/write"

删除功能:

"eventType":"Microsoft.Resources.ResourceDeleteSuccess"   
"operationName":"Microsoft.Web/sites/functions/delete"

代码已更新（运行.csx 文件）：

"eventType":"Microsoft.Resources.ResourceWriteSuccess"
"operationName":"Microsoft.Web/sites/hostruntime/vfs/run.csx/write"

配置已更改：

"eventType":"Microsoft.Resources.ResourceWriteSuccess"
"operationName":"Microsoft.Web/sites/config/write"

请注意，主题应用服务(目前在预览版中)的订阅可以根据以下属性进行筛选:

"eventType":"Microsoft.Web.AppUpdated"
"action":"ChangedAppSettings

订阅者可以从subject属性中找到函数应用（应用服务）和特定函数的名称。

以下示例显示了如何根据上述要求设置过滤属性:

"filter": {
  "subjectBeginsWith": "",
  "subjectEndsWith": "",
  "includedEventTypes": [
    "Microsoft.Resources.ResourceWriteSuccess",
    "Microsoft.Resources.ResourceDeleteSuccess"
  ],
"advancedFilters": [
  {
    "values": [
      "Microsoft.Web/sites/functions/write",
      "Microsoft.Web/sites/functions/delete",
      "Microsoft.Web/sites/hostruntime/vfs/run.csx/write",
      "Microsoft.Web/sites/config/write"
    ],
    "operatorType": "StringIn",
    "key": "Data.operationName"
  }
]

}
