使用 Resource Manager 範本在 Azure 事件方格中建立系統主題

本文說明如何使用 Resource Manager 範本來建立和管理系統主題。 如需系統主題的概觀,請參閱系統主題

先建立系統主題,然後建立事件訂閱

若要先在 Azure 來源上建立系統主題,然後為該主題建立事件訂閱,您可以使用類似下列的範本:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "storageName": {
            "type": "string",
            "defaultValue": "[concat('storage', uniqueString(resourceGroup().id))]",
            "metadata": {
                "description": "Provide a unique name for the Blob Storage account."
            }
        },
        "location": {
            "type": "string",
            "defaultValue": "[resourceGroup().location]",
            "metadata": {
                "description": "Provide a location for the Blob Storage account that supports Event Grid."
            }
        },

            "type": "string",
            "defaultValue": "subToStorage",
            "metadata": {
                "description": "Provide a name for the Event Grid subscription."
            }
        },
        "endpoint": {
            "type": "string",
            "metadata": {
                "description": "Provide the URL for the WebHook to receive events. Create your own endpoint for events."
            }
        },

            },
            "kind": "StorageV2",
            "location": "[parameters('location')]",
            "tags": {},
            "properties": {
                "accessTier": "Hot"
            }
        },
        {

            ],
            "properties": {

                "topicType": "Microsoft.Storage.StorageAccounts"
            }
        },
        {

                    ]
                }
            }
        }
    ]
}

建立事件訂閱戶時建立系統主題

若要隱含建立系統主題,在 Azure 來源上建立事件訂閱時,您可以使用下列範本:

            "metadata": {
                "description": "Provide a unique name for the Blob Storage account."
