如果您使用的是 Windows ，则可能要 使用WLAN API ，该 API 提供了“
WlanGetAvailableNetworkList（）”功能（有关用法，请参阅API文档）。我不知道有任何python包装器，
WLANAPI.DLL因此您可能必须使用ctypes自己包装它。我有一个初步的脚本可以做到这一点（“
为我工作” ），但这可能很麻烦。您将需要阅读文档以了解所有字段的含义：

标准选项是解析的输出
iwlist -scan。但是，如果您当前连接到无线局域网并且没有以root身份运行，则它仅返回当前连接的无线局域网。
如果您还需要更多，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。可以使用查询这两个管理器
dbus。除非您可以控制客户端在其系统上拥有的内容，否则可能需要同时支持这两个选项或至少一个选项，并具有的后备功能
iwlist。
