使用功能端点上的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，产生了以下模板。我进一步向其中添加了所需的模板项目（例如架构），但它始终会产生错误。我尝试过在网上寻找类似的模板，但似乎无法使用"endpointType": "AzureFunction"找到任何模板。此外，在资源浏览器中也没有提到可以进一步帮助我的部署。

任何人都可以帮助我解决问题吗？

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"
    }
}

                            ]
                        }

            }
        }
    ]
}

错误：

指定的主题属性与事件订阅范围中的预期主题不匹配

我不认为endpointType中的AzureFunction与documented是分开的。这只是webhook处理程序的特例。

此GitHub Repo包含示例ARM模板，您可以参考。这是您需要的确切代码段

...
"destination": {
    "endpointType": "WebHook",
    "properties": {
        "endpointUrl": "[concat(variables('functionUrl'), listKeys(resourceId('Microsoft.Web/sites/host/', variables('functionAppName'), 'default'),'2016-08-01').systemkeys.eventgrid_extension)]"
    }
}
...
