python - 如何在 Windows 下使用 netifaces 获取有意义的网络接口(interface)名称而不是 GUID？

Question

我使用 netifaces 模块。

import netifaces
print netifaces.interfaces()

但这显示了下面的结果:

 ['{CDC97813-CC28-4260-BA1E-F0CE3081DEC7}',
 '{846EE342-7039-11DE-9D20-806E6F6E6963}',
 '{A51BA5F0-738B-4405-975F-44E67383513F}',
 '{A646FA85-2EC6-4E57-996E-96E1B1C5CD59}',
'{B5DC7787-26DC-4540-8424-A1D5598DC175}']

我想在 Windows 中获得一个“友好”的接口(interface)名称，如“本地连接”。

我怎样才能得到它？

看起来 netifaces 让我们将信息从 Windows 注册表中提取出来。以下函数适用于 Windows 8.1 上的 Python 3.4。

获取连接名称...

import netifaces as ni
import winreg as wr
from pprint import pprint

def get_connection_name_from_guid(iface_guids):
    iface_names = ['(unknown)' for i in range(len(iface_guids))]
    reg = wr.ConnectRegistry(None, wr.HKEY_LOCAL_MACHINE)
    reg_key = wr.OpenKey(reg, r'SYSTEM\CurrentControlSet\Control\Network\{4d36e972-e325-11ce-bfc1-08002be10318}')
    for i in range(len(iface_guids)):
        try:
            reg_subkey = wr.OpenKey(reg_key, iface_guids[i] + r'\Connection')
            iface_names[i] = wr.QueryValueEx(reg_subkey, 'Name')[0]
        except FileNotFoundError:
            pass
    return iface_names

x = ni.interfaces()
pprint(get_connection_name_from_guid(x))

.. 在我的机器上生成:

['Local Area Connection* 12',
 'Bluetooth Network Connection',
 'Wi-Fi',
 'Ethernet',
 'VirtualBox Host-Only Network',
 '(unknown)',
 'isatap.{4E4150B0-643B-42EA-AEEA-A14FBD6B1844}',
 'isatap.{BB05D283-4CBF-4514-B76C-7B7EBB2FC85B}']

获取驱动程序名称...

import netifaces as ni
import winreg as wr
from pprint import pprint

def get_driver_name_from_guid(iface_guids):
    iface_names = ['(unknown)' for i in range(len(iface_guids))]
    reg = wr.ConnectRegistry(None, wr.HKEY_LOCAL_MACHINE)
    reg_key = wr.OpenKey(reg, r'SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}')
    for i in range(wr.QueryInfoKey(reg_key)[0]):
        subkey_name = wr.EnumKey(reg_key, i)
        try:
            reg_subkey = wr.OpenKey(reg_key, subkey_name)
            guid = wr.QueryValueEx(reg_subkey, 'NetCfgInstanceId')[0]
            try:
                idx = iface_guids.index(guid)
                iface_names[idx] = wr.QueryValueEx(reg_subkey, 'DriverDesc')[0]
            except ValueError:
                pass
        except PermissionError:
            pass
    return iface_names

x = ni.interfaces()
pprint(get_driver_name_from_guid(x))

...这给了我:

['Microsoft Wi-Fi Direct Virtual Adapter',
 'Bluetooth Device (Personal Area Network)',
 'Dell Wireless 1395 WLAN Mini-Card',
 'Broadcom 440x 10/100 Integrated Controller',
 'VirtualBox Host-Only Ethernet Adapter',
 '(unknown)',
 'Microsoft ISATAP Adapter',
 'Microsoft ISATAP Adapter']
