如何使用Python SDK实现PowerShell中的VNet与子网创建操作

前置依赖 #

• 安装所需SDK包：pip install azure-mgmt-network azure-identity
• 完成Azure身份认证：可通过本地执行az login，或配置服务主体环境变量完成身份校验

完整代码实现 #

以下代码完全对应你提供的PowerShell操作逻辑：

from azure.identity import DefaultAzureCredential
from azure.mgmt.network import NetworkManagementClient

# 基础参数配置，可按需修改
SUBSCRIPTION_ID = "替换为你的Azure订阅ID"
RESOURCE_GROUP_NAME = "CreateVNetQS-rg"
LOCATION = "EastUS"
VNET_NAME = "myVNet"
VNET_ADDRESS_PREFIX = "10.0.0.0/16"
SUBNET_NAME = "default"
SUBNET_ADDRESS_PREFIX = "10.0.0.0/24"

# 初始化网络管理客户端
credential = DefaultAzureCredential()
network_client = NetworkManagementClient(credential, SUBSCRIPTION_ID)

# 1. 对应PowerShell中New-AzVirtualNetwork操作，创建虚拟网络
vnet_operation = network_client.virtual_networks.begin_create_or_update(
    resource_group_name=RESOURCE_GROUP_NAME,
    virtual_network_name=VNET_NAME,
    parameters={
        "location": LOCATION,
        "address_space": {
            "address_prefixes": [VNET_ADDRESS_PREFIX]
        }
    }
)
virtual_network = vnet_operation.result()

# 2. 对应PowerShell中Add-AzVirtualNetworkSubnetConfig + Set-AzVirtualNetwork操作，添加子网并更新虚拟网络
subnet_operation = network_client.subnets.begin_create_or_update(
    resource_group_name=RESOURCE_GROUP_NAME,
    virtual_network_name=VNET_NAME,
    subnet_name=SUBNET_NAME,
    subnet_parameters={
        "address_prefix": SUBNET_ADDRESS_PREFIX
    }
)
subnet_config = subnet_operation.result()

print("虚拟网络与子网创建完成")

可选优化方案 #

你也可以在创建虚拟网络时直接传入子网配置，减少一次API调用，提升执行效率：

# 创建虚拟网络时直接携带子网配置
vnet_operation = network_client.virtual_networks.begin_create_or_update(
    resource_group_name=RESOURCE_GROUP_NAME,
    virtual_network_name=VNET_NAME,
    parameters={
        "location": LOCATION,
        "address_space": {
            "address_prefixes": [VNET_ADDRESS_PREFIX]
        },
        "subnets": [
            {
                "name": SUBNET_NAME,
                "address_prefix": SUBNET_ADDRESS_PREFIX
            }
        ]
    }
)
virtual_network = vnet_operation.result()
