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."
            }
        },
        "eventSubName": {
            "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."
            }
        },
        "systemTopicName": {
            "type": "String",
            "defaultValue": "mystoragesystemtopic",
            "metadata": {
                "description": "Provide a name for the system topic."
            }
        }
    },
    "resources": [
        {
            "name": "[parameters('storageName')]",
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2017-10-01",
            "sku": {
                "name": "Standard_LRS"
            },
            "kind": "StorageV2",
            "location": "[parameters('location')]",
            "tags": {},
            "properties": {
                "accessTier": "Hot"
            }
        },
        {
            "name": "[parameters('systemTopicName')]",
            "type": "Microsoft.EventGrid/systemTopics",
            "apiVersion": "2020-04-01-preview",
            "location": "[parameters('location')]",
            "dependsOn": [
                "[parameters('storageName')]"
            ],
            "properties": {
                "source": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageName'))]",
                "topicType": "Microsoft.Storage.StorageAccounts"
            }
        },
        {
            "type": "Microsoft.EventGrid/systemTopics/eventSubscriptions",
            "apiVersion": "2020-04-01-preview",
            "name": "[concat(parameters('systemTopicName'), '/', parameters('eventSubName'))]",
            "dependsOn": [
                "[resourceId('Microsoft.EventGrid/systemTopics', parameters('systemTopicName'))]"
            ],
            "properties": {
                "destination": {
                    "properties": {
                        "endpointUrl": "[parameters('endpoint')]"
                    },
                    "endpointType": "WebHook"
                },
                "filter": {
                    "includedEventTypes": [
                        "Microsoft.Storage.BlobCreated",
                        "Microsoft.Storage.BlobDeleted"
                    ]
                }
            }
        }
    ]
}

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."
            }
        },
        "location": {
            "type": "string",
            "defaultValue": "[resourceGroup().location]",
            "metadata": {

        }
    },
    "resources": [

            }
        },
        {
            "type": "Microsoft.Storage/storageAccounts/providers/eventSubscriptions",
            "name": "[concat(parameters('storageName'), '/Microsoft.EventGrid/', parameters('eventSubName'))]",
            "apiVersion": "2018-01-01",
            "dependsOn": [
                "[parameters('storageName')]"
            ],
            "properties": {
                "destination": {
                    "endpointType": "WebHook",

                    }
                },
                "filter": {
                    "subjectBeginsWith": "",
                    "subjectEndsWith": "",
                    "isSubjectCaseSensitive": false,
                    "includedEventTypes": [
                        "All"
                    ]
                }
            }
        }
    ]
