azure - 在函数端点上使用 ARM 创建 Eventgrid 订阅

Question

我正在尝试使用 ARM 模板在 Azure 存储帐户上创建 Eventgrid 订阅。在门户中手动创建它并进入高级设置，得到了下面的模板。我进一步向其中添加了所需的模板项(例如架构)，但它不断产生错误。我尝试在网上查找类似的模板，但似乎找不到任何使用 "endpointType": "AzureFunction" 的模板。此外，在资源浏览器中也没有提及可以进一步帮助我的部署。

有人可以帮我解决问题吗？

从门户创建期间生成的模板:

{
    "name": "test123",
    "properties": {
        "topic": "/subscriptions/<guid>/resourceGroups/<myGroup>/providers/Microsoft.Storage/storageAccounts/<myStorageAccount>",
        "destination": {
            "endpointType": "AzureFunction",
            "properties": {
                "resourceId": "/subscriptions/<guid>/resourceGroups/<myGroup>/providers/Microsoft.Web/sites/<myFunctionsApp>/functions/<myFunction>",
                "maxEventsPerBatch": 1,
                "preferredBatchSizeInKilobytes": 64
            }
        },
        "filter": {
            "includedEventTypes": [
                "Microsoft.Storage.BlobCreated"
            ],
            "advancedFilters": [
                {
                    "operatorType": "StringContains",
                    "key": "Subject",
                    "values": [
                        "-original"
                    ]
                }
            ]
        },
        "labels": [],
        "eventDeliverySchema": "EventGridSchema"
    }
}

完整模板:

                            "operatorType": "StringContains",
                            "key": "Subject",
                            "values": [
                                "-original"
                            ]
                        }
                    ]
                },
                "labels": [
                ],
                "eventDeliverySchema": "EventGridSchema"
            }
        }
    ]
}

错误:

The specified topic property does not match the expected topic from the event subscription scope

我一直在尝试通过 Azure 工具链(ARM 模板/CLI/REST)中的任何选项来执行完全相同的操作。我查看了门户的调用，发现它正在使用您显示的 2020-01-01-preview EventGrid API。

经过一些测试，我可以确认新的 API 允许部署具有 AzureFunction EndpointType 的订阅，如下所示:

{
  "name": "[concat(variables('eventDomainName'), '/Microsoft.EventGrid/', variables('subscriptionName'))]",
  "type": "Microsoft.EventGrid/domains/providers/eventSubscriptions",
  "location": "[variables('location')]",
  "apiVersion": "2020-01-01-preview",
  "properties": {
    "destination": {
        "endpointType": "AzureFunction",
        "properties": {
            "resourceId": "[resourceId('Microsoft.Web/sites/functions/', parameters('functionAppName'), parameters('functionName'))]"
        }
    },
    "filter": "[parameters('subscriptionProperties').filter]"
  }
}

您的问题似乎与尝试定位 AzureFunction 无关，并且您使用的是正确的 API 版本，因此似乎并非如此。

我认为问题出在你的“Type”值上。我认为应该采用这种格式://providers/eventSubscriptions

所以它将是 Microsoft.Storage/storageAccounts/providers/eventSubscriptions。
