Bicep 更新砖块代码，现在我收到变量 vnetArray 的错误，该变量返回所有 vnet 及其各自子网和子网 ID 的列表

Question

自从不久前的 Bicep 更新以来，我收到变量 vnetArray 的错误，该变量返回所有 vnet 及其各自的子网和子网 ID 的列表。我认为解决方案很简单，但我似乎找不到解决方案。

我在 mainSpoke.bicep 变量 vnetArray 中的 virtualNetworkModule[i].outputs.vnetName 和 virtualNetworkModule[i].outputs.subnetIDArray 中遇到的错误：“此表达式正在变量“vnetArray”的 for-body 中使用，需要可以在部署开始时计算的值。virtualNetworkModule 的属性“outputs”无法在开始时计算。virtualNetworkModule 可以在开始时计算的属性包括“name”.bicep(BCP182)”

mainSpoke.bicep

var vnetArray = [for i in range(0, length(virtualNetwork)): { name: virtualNetworkModule[i].outputs.vnetName, value: virtualNetworkModule[i].outputs.subnetIDArray }]

module virtualMachineDeploymentModule '../../Modules/Compute/virtualMachineDeployment/virtualMachineDeploy.bicep' = [for vmConfiguration in virtualMachines: {

我可以确认 2 个虚拟网络已成功创建并具有相应的子网，我只是似乎无法映射返回所有 vnet 及其各自子网和子网 ID 列表的变量。 Var vnetArray 将在 virtualMachineDeploymentModule 中用于以下用途：

// This variable is used to create an object of the vnets and subnets lists.
var vnetObject = toObject(vnets, i => i.name, i => toObject(i.value, j => j.name, j => j.resourceId))

有点难看，但你可以将 vnet 创建包装到它自己的模块中：

// file virtualNetworkWrapper.bicep

param customerName string
param virtualNetwork array

// Deploy Network resources
module virtualNetworkModule 'virtualNetwork.bicep' = [for vnet in virtualNetwork: {
  name: 'virtualnetworkdeploy-${vnet.name}'
  params: {
    virtualNetworkName: '${customerName}-${vnet.name}'
    location: vnet.location
    subnets: vnet.subnets
    networkSecurityGroupId: networkSecurityGroupModule.outputs.networkSecurityGroupId
    addressPrefixes: vnet.addressPrefixes
  }
}]

output vnetArray array = [for i in range(0, length(virtualNetwork)): { name: virtualNetworkModule[i].outputs.vnetName, value: virtualNetworkModule[i].outputs.subnetIDArray }]

然后从你的主目录看起来像这样：

// file mainSpoke.bicep

param customerName string
param virtualNetwork array

module virtualNetworkModule '../../Modules/Network/virtualNetwork/virtualNetworkWrapper.bicep' = {
  name: 'allvirtualnetworkdeploy-${customerName}'
  params: {
    customerName: customerName
    virtualNetwork: virtualNetwork
  }
}

var vnetArray = virtualNetworkModule.outputs.vnetArray
