Question

我编写了一个ARM模板，以在现有存储帐户上创建事件订阅，我需要在其中监听特定blob容器的blob.created和blob.deleted事件，并将其发送到Azure eventgrid触发函数应用程序。

functionapp已部署在Azure https://myfunctionapp.azurewebsites.net中，我很难通过ARM模板创建事件订阅。请注意，我已经使用API版本2020-01-01-preview来将AzureFunction作为终结点。模板如下：

{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
    "appName": {
        "type": "string",
        "metadata": {
            "description": "Name of the function app"
        }
    },
    "functionName": {
        "type": "string",
        "defaultValue": "MyFunction",
        "metadata": {
            "description": "Name of the function"
        }
    },
    "eventSubName": {
        "type": "string",
        "defaultValue": "myfunctionappsub",
        "metadata": {
            "description": "The name of the event subscription to create."
        }
    },
    "storageName": {
        "type": "string",
        "metadata": {
            "description": "Storage account name"
        }
    },
    "location": {
        "type": "string",
        "defaultValue": "[resourceGroup().location]",
        "metadata": {
            "description": "Storage account location"
        }
    },
    "containerNamefilter": {
        "type": "string",
        "defaultValue": "-inputblob",
        "metadata": {
            "description": "Container name filter"
        }
    }
},
"variables": {
    "functionAppName": "[resourceId('Microsoft.Web/sites/functions/', parameters('appName'), parameters('functionName'))]"
},
"resources": [
    {
        "type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
        "name": "[concat(parameters('storageName'), '/Microsoft.EventGrid/', parameters('eventSubName'))]",
        "apiVersion": "2020-01-01-preview",
        "dependsOn": [
            "[parameters('storageName')]"
        ],
        "properties": {
            "destination": {
                "endpointType": "AzureFunction",
                "properties": {
                    "resourceId": "[variables('functionAppName')]"
                }
            },
            "filter": {
                "subjectBeginsWith": "",
                "subjectEndsWith": "",
                "isSubjectCaseSensitive": false,
                "includedEventTypes": [
                    "Microsoft.Storage.BlobCreated",
                    "Microsoft.Storage.BlobDeleted"
                ],
                "advancedFilters": [
                    {
                        "key": "subject",
                        "operatorType": "StringContains",
                        "value": "[parameters('containerfilter')]"
                    }
                ]
            }
        }
    }
]
}

这是我在管道上尝试运行时遇到的错误：

我在这里做错什么了吗？我是ARM模板的新手。

如果要为现有存储帐户创建事件网格订阅，请参考以下模板

{
"$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",

{
        "type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
        "name": "[concat(parameters('storageName'), '/Microsoft.EventGrid/', parameters('eventSubName'))]",
        "apiVersion": "2020-01-01-preview",
        "properties": {
            "destination": {
                "endpointType": "AzureFunction",
                "properties": {
                    "resourceId": "[variables('functionId')]"
                }
            },
            "filter": {
                "subjectBeginsWith": "",

                "includedEventTypes": [
                    "Microsoft.Storage.BlobCreated",
                    "Microsoft.Storage.BlobDeleted"
                ],
                "advancedFilters": [
                    {
                        "key": "subject",
                        "operatorType": "StringContains",
                        "value": "[parameters('containerNamefilter')]"
                    }
                ]
            }
        }
    }

]
}

如何在Azure模板中将AzureFunction添加为事件订阅端点？
