如何使用ARM模板创建多个Service Bus主题？

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

az deployment group create --resource-group <resource-group-name> --template-file <template-file-path> --parameters resourceGroupName=<resource-group-name> namespaceName=<namespace-name> topics=<topics-json-array>
