Question

我的对象的属性数量不相等（并且希望保持这种状态），即第二个对象缺少属性“ routeTable”

"subnets": {
"value":[
{
"name": "GatewaySubnet",
"addressPrefix": "10.2.0.0/24",
"networkSecurityGroup":"NSG-AllowAll",
"routeTable":"UDR-Default"
},
{
"name":"UnTrusted",
"addressPrefix":"10.2.1.0/24",
"networkSecurityGroup":"NSG-AllowAll",
}]}

现在，我不知道如何遍历对象时检查属性是否存在。由于缺少属性“ id”，下面给出错误信息：“ [[resourceID（'Microsoft.Network/routeTables'，parameters（'subnets'）[copyIndex（'subnets']]。routeTable）]”

我对嵌套“ id”属性的条件似乎无效，即

"networkSecurityGroup": {
"id": "[resourceID('Microsoft.Network/networkSecurityGroups', if(equals(parameters('subnets')[copyIndex('subnets')].networkSecurityGroup, ''), json('null'), parameters('subnets')[copyIndex('subnets')].networkSecurityGroup))]"
}

好的，这是我能想到的最好的方法

您可能可以通过一些嵌套循环使它更好。但这也可以。

PS。我在动态创建名称时曾为nsg \ udr使用不同的名称，在您的方案中，如果存在这些名称，它将使用相同的名称（这不会）。
