Python如何过滤JSON数组中指定Intel网卡的MAC地址？

现有代码的问题 #

• 判断条件误用赋值符号=，且需求是网卡名称包含指定字符串，不是完全相等，应该用in关键字做包含判断
• 循环内固定取索引为0的网卡信息，无论匹配到哪个网卡，都只会输出第一个网卡的名称，逻辑错误
• 没有做两类网卡的分类筛选和存储逻辑

可直接运行的修正代码 #

import json

response ='{"message_response":{"compdetailssummary":{"computer_summary":{"computer_name":"ABC","primary_owner":"Windows User","domain_name":"WORKGROUP"},"computer_network_adapter_summary":[{"dhcp_status":"Enabled","adapter_name":"[00000001] Fortinet Virtual Ethernet Adapter (NDIS 6.30)","mac_address":"00:00:0F:00:00:01","dhcp_server":"-","ip_address":"-","gateway":"-"},{"dhcp_status":"Enabled","adapter_name":"[00000004] Intel(R) Ethernet Connection I219-LM","mac_address":"00:00:0F:00:00:01","dhcp_server":"-","ip_address":"-","gateway":"-"},{"dhcp_status":"Enabled","adapter_name":"[00000005] Intel(R) Dual Band Wireless-AC 8260","mac_address":"00:00:0F:00:00:01","dhcp_server":"1.1.9.1","ip_address":"1.2.9.3","gateway":"1.1.8.1"},{"dhcp_status":"Enabled","adapter_name":"[00000007] Bluetooth Device (Personal Area Network)","mac_address":"00:00:0F:00:00:01","dhcp_server":"-","ip_address":"-","gateway":"-"},{"dhcp_status":"Disabled","adapter_name":"[00000002] PPPoP WAN Adapter","mac_address":"-","dhcp_server":"--","ip_address":"--","gateway":"--"},{"dhcp_status":"Enabled","adapter_name":"[00000003] Fortinet SSL VPN Virtual Ethernet Adapter","mac_address":"00:00:0F:00:00:01","dhcp_server":"--","ip_address":"--","gateway":"--"}]}}}'
json_data = json.loads(response)

# 提前提取公共字段，减少重复写长路径
computername = json_data['message_response']['compdetailssummary']['computer_summary']['computer_name']
all_adapters = json_data['message_response']['compdetailssummary']['computer_network_adapter_summary']

# 分别存储两类网卡的MAC地址，适配单设备多同类型网卡的场景
eth_mac = []
wifi_mac = []

for item in all_adapters:
    name = item["adapter_name"]
    mac = item["mac_address"]
    if "Intel(R) Ethernet" in name:
        eth_mac.append(mac)
        print(f"以太网适配器：{name}，MAC：{mac}")
    elif "Intel(R) Dual Band Wireless" in name:
        wifi_mac.append(mac)
        print(f"WiFi适配器：{name}，MAC：{mac}")

# 输出最终汇总结果
print(f"\n设备名称：{computername}")
print(f"全部Intel以太网MAC：{eth_mac}")
print(f"全部Intel WiFi MAC：{wifi_mac}")

运行效果 #

用你提供的样例JSON运行后，会自动过滤掉虚拟网卡、蓝牙网卡等无关内容，输出匹配到的1个以太网和1个WiFi网卡的信息，即使返回的网卡数量超过12个也能正常筛选。
