如何使用 Python 在 Windows 上检索附近无线 LAN 网络的信号强度？

Question

如何使用 Python 在 Windows 上检索附近无线 LAN 网络的信号强度？

我想显示或绘制数值。

Answer 1

如果您使用的是 Windows，您可能想要使用 WLAN API，它提供了“WlanGetAvailableNetworkList()”函数（有关用法，请参阅API docs） .我不知道WLANAPI.DLL 有任何python 包装器，因此您可能必须使用ctypes 自己包装它。我有一个可以执行此操作的初步脚本（为我工作），但它可能很笨拙。您需要阅读文档以了解所有字段的含义：

在 linux 上，您有几个选择：

标准选项是解析iwlist -scan 的输出。但是，如果您当前连接到一个 wlan 并且没有以 root 身份运行，它只会返回当前连接的 wlan。

如果您需要更多，最好的方法是查询无线管理器守护程序。在现代 Linux 上，这通常是 NetworkManager，尽管 wicd 变得越来越流行。可以使用dbus 查询这两个管理器。除非您可以控制客户端在其系统上的内容，否则您可能需要同时支持这两个选项，或者至少支持一个选项并备用iwlist。

Answer 2

如果您不想处理 Windows API，您可以使用here 所示的方法并稍作修改。

你可以使用这个命令：

netsh wlan show networks mode=Bssid

使用此代码

import subprocess
results = subprocess.check_output(["netsh", "wlan", "show", "network", "mode=Bssid"])

这将为您提供以百分比表示的附加“信号”信息。这可以使用this method 转换为RSSI。

Answer 3

所以.. 我自己基于@fmarks 代码（这对我来说更安全），你应该添加 WlanScan 函数，否则 RSSI 值将不会刷新。。 p>

这是我的扩展代码！

@fmarks 的所有道具！

@fmark 我只想对这篇精彩的帖子表示非常感谢。在我的工作中，我一直在尝试从 Windows 中连接的 AP 获取 RSSI，您应该非常感谢我终于完成了它。我目前正在列出所有 AP，但我正在修改它。我想对您的代码提出建议。我对 C 或 Python CTypes 模块不是很有经验，但我想我可能发现了一个可能的错误。我真的不确定它有什么不同，但我注意到了：

你可以这样定义枚举：

DOT11_BSS_TYPE = c_uint
(dot11_BSS_type_infrastructure,
 dot11_BSS_type_independent,
 dot11_BSS_type_any) = map(DOT11_BSS_TYPE, xrange(1, 4))

但其他时候你定义的东西非常相似：

DOT11_PHY_TYPE = c_uint
dot11_phy_type_unknown      = 0
dot11_phy_type_any          = 0
dot11_phy_type_fhss         = 1
dot11_phy_type_dsss         = 2
dot11_phy_type_irbaseband   = 3
dot11_phy_type_ofdm         = 4
dot11_phy_type_hrdsss       = 5
dot11_phy_type_erp          = 6
dot11_phy_type_ht           = 7
dot11_phy_type_IHV_start    = 0x80000000
dot11_phy_type_IHV_end      = 0xffffffff 

我认为第二个片段应该像第一个那样建模，但我可能错了。这是我的想法：

DOT11_PHY_TYPE = c_uint
(dot11_phy_type_unknown,
 dot11_phy_type_any,
 dot11_phy_type_fhss,
 dot11_phy_type_dsss,
 dot11_phy_type_irbaseband,
 dot11_phy_type_ofdm,
 dot11_phy_type_hrdsss,
 dot11_phy_type_erp,
 dot11_phy_type_ht,
 dot11_phy_type_IHV_start,
 dot11_phy_type_IHV_end) = map(DOT11_PHY_TYPE,
                               [0,0,1,2,3,4,
                                5,6,7,0x80000000,
                                0xffffffff])

这样，这些值将正确映射到 DOT11_PHY_TYPE。也许我完全错了，但对于像我这样的未来人，我只是希望这里偶然发现的任何东西都是正确的:) 再次感谢@fmark。
