今天 使用 pcap库 选网卡发现 findalldevs() 调出来的网卡基本上不可读

那么我们能不能将这个值转换为我们可读的值呢
这里参考了以下代码

import platform
if 'Windows' in platform.platform():
    import winreg as wr
IF_REG = r'SYSTEM\CurrentControlSet\Control\Network\{4d36e972-e325-11ce-bfc1-08002be10318}'
##这个函数就是将网卡的名字转换为 findalldevs 返回的值
def getInterfaceByName(name):
    '''Get guid of interface from regedit of windows system
    Args:
        name: interface name
    Returns:
        An valid guid value or None.
    Example:
        getInterfaceByName('eth0')
    '''
    reg = wr.ConnectRegistry(None, wr.HKEY_LOCAL_MACHINE)
    reg_key = wr.OpenKey(reg, IF_REG)
    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 + r'\Connection')
            Name = wr.QueryValueEx(reg_subkey, 'Name')[0]
            wr.CloseKey(reg_subkey)
            if Name == name:
                return r'\Device\NPF_' + subkey_name
        except FileNotFoundError as e:
            pass
 
    return None

这里直接上代码

import platform
if 'Windows' in platform.platform():
    import winreg as wr
IF_REG = r'SYSTEM\CurrentControlSet\Control\Network\{4d36e972-e325-11ce-bfc1-08002be10318}'
def FindalldevsName(devs):
    reg = wr.ConnectRegistry(None, wr.HKEY_LOCAL_MACHINE)
    reg_key = wr.OpenKey(reg, IF_REG)
    try:
        reg_subkey = wr.OpenKey(reg_key, devs + r'\Connection')
        return wr.QueryValueEx(reg_subkey, 'Name')[0]
    except FileNotFoundError as e:
        ...
    return None

findOb = = pcap.findalldevs()
for i in name:
    FindalldevsName(i.split('_')[1])
