这取决于我们在这里谈论多少主题。如果你只是创建一个小数字，那么我会这样做;

TopicsAndSubs.bicep

@description('Name of the Service Bus namespace')
param serviceBusNamespaceName string

@description('Name of the Topic')
param serviceBusTopicName string = 'theweather'

param topicSubscriptions int = 3

resource serviceBusNamespace 'Microsoft.ServiceBus/namespaces@2022-10-01-preview' existing = {
  name: serviceBusNamespaceName
}

resource serviceBusTopic 'Microsoft.ServiceBus/namespaces/topics@2022-10-01-preview' = {
  parent: serviceBusNamespace
  name: serviceBusTopicName
  properties: {

  }

  resource sub 'subscriptions' = [for i in range(0,topicSubscriptions): {
    name: 'sub-${i}'
    properties: {}
  }]
}

但是，如果它更古怪，那么你需要使用模块（一个单独的主题文件和一个订阅文件）。类似这样的东西;

Topics.bicep

@description('Name of the Service Bus namespace')
param serviceBusNamespaceName string

@description('Name of the Topic')
param topicsAndSubscriptions array = [
  {
    name: 'notification'
    subscriptions: [
      'none'
      'ntwo'
      'nthree'
      'nfour'
    ]
  }
  {
    name: 'analysis'
    subscriptions: [
      'aone'
      'atwo'
      'athree'
      'afour'
    ]
  }
]

resource serviceBusNamespace 'Microsoft.ServiceBus/namespaces@2022-10-01-preview' existing = {
  name: serviceBusNamespaceName
}

resource serviceBusTopic 'Microsoft.ServiceBus/namespaces/topics@2022-10-01-preview' = [ for topic in topicsAndSubscriptions: {
  parent: serviceBusNamespace
  name: topic.name
  properties: {

  }
}]

module subs 'sub.bicep' = [ for topic in topicsAndSubscriptions: {
  name: '${topic.name}-subs'
  params: {
    servicebusNamespaceName: serviceBusNamespaceName
    topicName: topic.name
    subscriptions: topic.subscriptions
  }
}]

订阅.bicep

param servicebusNamespaceName string
param topicName string
param subscriptions array = ['asubscription','anotherone']

resource sub 'Microsoft.ServiceBus/namespaces/topics/subscriptions@2022-10-01-preview' = [for i in subscriptions: {
  name: '${servicebusNamespaceName}/${topicName}/${i}'
  properties: {}
}]
