azure 二头肌 : get array out of an array of objects

Question

我有一个参数，它是一个对象数组。对象中的元素之一(“peers”)是另一个对象数组。我想动态提取对等数组并联合/连接它们并保留“vnetid”作为引用。

param vnets array = [
  {
    vnetid: 0
    name: '0-test-test'
    addressPrefix: '10.10.74.0/22'
    peers: [
      {
        name: '0-to-1'
        peerToId: 1
      }
    ]
    subnets: [
      {
        name: 'GatewaySubnet'
        addressPrefix: '10.10.74.0/25'
      }
      {
        name: 'AzureFirewallSubnet'
        addressPrefix: '10.10.74.128/25'
      }
    ]
  }
  {
    vnetid: 1
    name: '1-test-test'
    addressPrefix: '10.10.68.0/22'
    peers: [
      {
        name: '1-to-0'
        peerToId: 0
      }
    ]
    subnets: [
      {
        name: 'subnet1'
        addressPrefix: '10.10.68.0/25'
      }
      {
        name: 'subnet2'
        addressPrefix: '10.10.69.0/24'
      }
    ]
  }
]

所需的新数组:

param peers array = [
  {
    vnetid: 0
    name: '0-to-1'
    peerToId: 1
  }
  {
    vnetid: 1
    name: '1-to-0'
    peerToId: 0
  }
]

我找不到解决方案。我尝试过 concat、union、items 和基本上所有的数组函数。没有任何运气。

您可以使用map和 flatten lambda 函数如所述 here :

var peers = flatten(
  // Iterate through the vnets
  map(vnets, vnet => 
     // Iterate through the peers and add vnetid to the peer object  
     map(vnet.peers, peer => 
       union({ vnetid: vnet.vnetid }, peer)
    )
  )
)

output peers array = peers
