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

问题描述

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.当我遍历基于 NumberOfItems 的网络数组时，它只向我显示第一个网络，而除此之外的任何内容都会给我 IndexError: invalid index.这是我的代码

from win32wifi.Win32Wifi import WlanScan, WlanOpenHandle, WlanGetProfileList, WlanEnumInterfaces, WlanGetAvailableNetworkList, WlanCloseHandle, WlanConnect句柄 =WlanOpenHandle()接口 = WlanEnumInterfaces(handle).contentsg= interfaces.InterfaceInfo[0].InterfaceGuidWlanScan(手柄，g)网络 = WlanGetAvailableNetworkList(handle, g).contentsprint("网络数量:",networks.NumberOfItems)对于我在范围内(networks.NumberOfItems):打印('网络:'，networks.Network[i].dot11Ssid.SSID)WlanCloseHandle(句柄)

这个问题与这个问题相关

解决方案

我在评论中说得太早了(所以我删除了它).显然，win32wifi.Win32Wifi 提供了许多封装 CTypes 的功能，但是由于诸如 from win32wifi.Win32NativeWifiApi import * 之类的语句，命名空间受到了污染.无论如何，这是一个例子.

code00.py:

#!/usr/bin/env python3导入系统从 win32wifi 导入 Win32Wifi as ww定义主():接口 = ww.getWirelessInterfaces()print("WLAN 接口:{:d}".format(len(interfaces)))对于 idx0，enumerate(interfaces) 中的接口:print("\n {:d}\n GUID: [{:s}]\n Description: [{:s}]\n State: [{:s}]".format(idx0, interface.guid_string, interface.description, interface.state_string))网络 = ww.getWirelessAvailableNetworkList(接口)print("\n 网络:{:d}".format(len(networks)))对于 idx1，枚举中的网络(网络):print("\n {:d}\n SSID: [{:s}]\n Profile: [{:}]\n Connectable: {:}\n 信号质量: {:d}\n 标志: {:d}\n 安全性:{:}\n 身份验证:{:}".format(idx1、network.ssid.decode()、network.profile_name、network.connectable、network.signal_quality、network.flags、network.security_enabled、network.auth))如果 __name__ == "__main__":print("Python {0:s} {1:d}bit on {2:s}\n".format(" ".join(item.strip() for item in sys.version.split("\n")), 64 如果 sys.maxsize > 0x100000000 否则 32, sys.platform))main(*sys.argv[1:])打印(\n完成.")

输出:

虽然它与这个问题无关，但我在处理 .可能想看看.

I am trying to get the list of all available networks using WlanGetAvailableNetworkList. The scan returns an object which contains NumberOfItems. When I loop over the array of networks based NumberOfItems it only shows me the first network and anything beyond that gives me IndexError: invalid index.here's my code

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)

解决方案

I spoke too soon in my comment (so I deleted it). Apparently, win32wifi.Win32Wifi offers lots of functionalities that wrap CTypes, but the namespace is polluted because of statements like from win32wifi.Win32NativeWifiApi import *. Anyway, here's an example.

code00.py:

#!/usr/bin/env python3

import sys
from win32wifi import Win32Wifi as ww


def main():
    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 {0:s} {1:d}bit on {2:s}\n".format(" ".join(item.strip() for item in sys.version.split("\n")), 64 if sys.maxsize > 0x100000000 else 32, sys.platform))
    main(*sys.argv[1:])
    print("\nDone.")

Although it's not related to this question, I found (and fixed) some Win32WiFi bugs while working on [SO]: How to connect to WiFi network using Python 3? (@CristiFati's answer). Might want to take a look.
