python - 无法在Python中使用WlanGetAvailableNetworkList获取所有可用网络

Question

我正在尝试使用WlanGetAvailableNetworkList获取所有可用网络的列表。扫描返回一个包含 NumberOfItems 的对象。当我循环基于NumberOfItems的网络数组时，它只显示第一个网络，除此之外的任何内容都会给我IndexError:无效索引。这是我的代码

from win32wifi.Win32Wifi import WlanScan, WlanOpenHandle, WlanGetProfileList, WlanEnumInterfaces, WlanGetAvailableNetworkList, WlanCloseHandle, WlanConnect

handle =WlanOpenHandle()
interfaces = WlanEnumInterfaces(handle).contents
g= interfaces.InterfaceInfo[0].InterfaceGuid
WlanScan(handle, g)
networks= WlanGetAvailableNetworkList(handle, g).contents
print("Number of networks : ", networks.NumberOfItems)
for i in range(networks.NumberOfItems):
    print('Network : ', networks.Network[i].dot11Ssid.SSID )

WlanCloseHandle(handle)

我在评论中说得太早了(所以我删除了它)。显然，win32wifi.Win32Wifi 提供了许多包装 CType 的功能，但命名空间由于诸如 from win32wifi.Win32NativeWifiApi import * 之类的语句而受到污染。无论如何，这是一个例子。

code00.py:

#!/usr/bin/env python3

import sys

from win32wifi import Win32Wifi as ww


def main(*argv):
    interfaces = ww.getWirelessInterfaces()
    print("WLAN Interfaces: {:d}".format(len(interfaces)))
    for idx0, interface in enumerate(interfaces):
        print("\n  {:d}\n  GUID: [{:s}]\n  Description:  [{:s}]\n  State: [{:s}]".format(idx0, interface.guid_string, interface.description, interface.state_string))
        networks = ww.getWirelessAvailableNetworkList(interface)
        print("\n  Networks: {:d}".format(len(networks)))
        for idx1, network in enumerate(networks):
            print("\n    {:d}\n    SSID: [{:s}]\n    Profile: [{:}]\n    Connectable: {:}\n    Signal quality: {:d}\n    Flags: {:d}\n    Security: {:}\n    Auth: {:}".format(
                idx1, network.ssid.decode(), network.profile_name, network.connectable, network.signal_quality, network.flags, network.security_enabled, network.auth))


if __name__ == "__main__":
    print("Python {:s} {:03d}bit on {:s}\n".format(" ".join(elem.strip() for elem in sys.version.split("\n")),
                                                   64 if sys.maxsize > 0x100000000 else 32, sys.platform))
    rc = main(*sys.argv[1:])
    print("\nDone.")
    sys.exit(rc)

输出:

虽然与这个问题无关，但我在处理 [SO]: How to connect to WiFi network on Windows (@CristiFati's answer) 时发现(并修复了)一些 Win32WiFi 错误。可能想看一下。
