【问题描述】：

我正在尝试创建一个包含多个网络安全组 (NSG) 的 json 对象，以便构建它们并使用“计数”应用到 vNet 子网以最小化模板代码。 The Microsoft Documentation covers how to create an object for one NSG's settings 在“在复制循环中使用属性对象”部分下。这需要我为我需要的每个 NSG 创建一个新的参数对象，并为每个 NSG 创建冗长的模板代码。

我目前正在使用以下参数对象来保存有关虚拟网络的所有信息，包括 NSG。 NSG 将绑定到子网，第一个子网“GatewaySubnet”被排除在需要 NSG 之外

"vNetProperties": 
    "value": 
        "vNetAddressSpace": "10.136.0.0/16",
        "subnetNames": [
            "GatewaySubnet",
            "Kemp-frontend-subnet",
            "AD-backend-subnet"
        ],
        "subnetRanges": [
            "10.136.0.0/27",
            "10.136.1.0/24",
            "10.136.2.0/24"
        ],
        "networkSecurityGroups": 
            "value": 
                "kempNSG": 
                    "value": 
                        "securityRules": [

                                "priority": 100,
                                "sourceAddressPrefix": "*",
                                "destinationAddressPrefix": "10.0.0.0/24",
                                "sourcePortRange": "*",
                                "destinationPortRange": "443",
                                "access": "Allow",
                                "protocol": "Tcp"
                            ,
                            
                                "name": "HTTP",
                                "description": "allow HTTP connections",

                                "sourceAddressPrefix": "*",
                                "destinationAddressPrefix": "10.0.0.0/24",
                                "sourcePortRange": "*",

                                "protocol": "Tcp"
                            
                        ]
                    
                ,
                "adNSG": 
                    "value": 
                        "securityRules": [
                            
                                "name": "RDPAllow",
                                "description": "allow RDP connections",
                                "direction": "Inbound",
                                "priority": 100,
                                "sourceAddressPrefix": "*",
                                "destinationAddressPrefix": "10.0.0.0/24",
                                "sourcePortRange": "*",
                                "destinationPortRange": "3389",
                                "access": "Allow",
                                "protocol": "Tcp"
                            
                        ]
                    
                
            
        
    

我处理对象的模板代码如下：

      "apiVersion": "2016-06-01",
      "type": "Microsoft.Network/networkSecurityGroups",
      "name": "[concat(parameters('vNetProperties').subnetNames[copyIndex(1)], '-nsg')]",
      "location": "[resourceGroup().location]",
      "copy": 
        "name": "NSGs",
        "count": "[length(array(parameters('vNetProperties').networkSecurityGroups))]"
      ,
      "properties": 
        "copy": [
          
            "name": "securityRules",
            "count": "[length(array(parameters('vNetProperties').networkSecurityGroups[copyIndex('securityRules')]))]",
            "input": 
              "description": "[parameters('vNetProperties').networkSecurityGroups[0].securityRules[0].description]",
              "priority": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].priority]",
              "protocol": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].protocol]",
              "sourcePortRange": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].sourcePortRange]",
              "destinationPortRange": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].destinationPortRange]",
              "sourceAddressPrefix": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].sourceAddressPrefix]",
              "destinationAddressPrefix": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].destinationAddressPrefix]",
              "access": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].access]",
              "direction": "[parameters('vNetProperties').networkSecurityGroups[copyIndex('NSGs')].securityRules[copyIndex('securityRules')].direction]"
            
          
        ]
      
    

我现在的代码肯定不起作用。我现在需要验证这种类型的逻辑在 ARM 中甚至是可能的。是否有可能有一个数组，其中数组中的每个项目都是一个数组本身，并以 array1[i].array2[j].name 这样的方式引用两个级别的数组？

【参考方案1】：

这种方法行不通，你不能在同一个资源中拥有循环和属性复制循环，并且像这样引用对象（可悲）。

您的解决方法是为每个父对象（networkSecurityGroups）创建一个嵌套部署，并在该部署中创建一个属性复制循环（安全规则）。这将起作用，因为您将只有一个复制循环。
