我正在尝试使用wpa_supplicant python 模块通过 wpa 连接到 wifi。在 API 中，我找到了一个名为select_network的函数，它似乎可以帮助我与 wifi AP 关联，但我不明白输入参数的含义。

输入参数称为所需网络的 D-bus 对象路径。谷歌搜索后，我找不到任何有关使用此功能的示例。

更新

我使用 d-feet 查看 /fi/w1/wpasupplicant1 下的对象路径。如下所示：

/fi/w1/wpa_supplicant1
/fi/w1/wpa_supplicant1/interfaces/7
/fi/w1/wpa_supplicant1/interfaces/7/BSSs/14
/fi/w1/wpa_supplicant1/interfaces/7/Networks/0
/fi/w1/wpa_supplicant1/interfaces/7/Networks/1

还是不知道怎么处理 select_network 这个函数。但是我找到了以下链接：

此链接描述了如何使用 dbus 模块直接连接到 wifi。

任何提示将不胜感激。

除此之外，对于那些努力让它工作的人，您需要通过添加 -u（启用 dbus）在 wpa_supplicant 应用程序守护程序上启用 DBUS 功能

关于如何使用它的快速示例，只是一个粗略的编程示例。

from wpa_supplicant.core import WpaSupplicantDriver
from twisted.internet.selectreactor import SelectReactor
import threading
import time
import errno
import sys
import types
import netifaces
import dbus

class PythonWifiScanner:

    wifiAccessPoints = []

    def __init__(self,reactor):
        self._reactor = reactor
        threading.Thread(target=self._reactor.run, kwargs={'installSignalHandlers': 0}).start()
        time.sleep(0.2)  # let reactor start
        self.driver = WpaSupplicantDriver(reactor)
        self.supplicant = self.driver.connect()

        # get network interfaces

        self.net_iface = netifaces.interfaces()

    def get_configured_networks(self,interfaceNumber):
        return self.supplicant.get_interface(self.net_iface[interfaceNumber].decode()).get_networks()

    def get_single_wpa_interface(self,interfaceNumber):
        return self.supplicant.get_interface(self.net_iface[interfaceNumber].decode())

    def get_interfaces(self):
        return self.net_iface

    def select_network(self,network_path,interfaceNumber):
        return self.supplicant.get_interface(self.net_iface[interfaceNumber].decode()).select_network(network_path)

    def add_network(self,network_cfg,interfaceNumber):
        return self.supplicant.get_interface(self.net_iface[interfaceNumber].decode()).add_network(network_cfg)

    def scan_interface_for_networks(self,interfaceNumber):
        # Get interface and scan the network
        interface = self.supplicant.get_interface(self.net_iface[interfaceNumber].decode())
        wifiNetworks = interface.scan(block=True)
        self.wifiAccessPoints = [] 
        for singleWifi in wifiNetworks:
            self.wifiAccessPoints.append(singleWifi.get_ssid())
        return wifiNetworks

# Start a simple Twisted SelectReactor

sample_network_cfg  = {}
sample_network_cfg['psk'] = "EnterYourKeyHere"
sample_network_cfg['ssid'] = "EnterYourWifiHere"
sample_network_cfg['key_mgmt'] = "WPA-PSK"
reactor = SelectReactor()
dave=PythonWifiScanner(reactor)
value = None
bus = dbus.SystemBus()


print "Interface:" + dave.get_interfaces()[3]

# scan for available networks

for singleWifi in dave.scan_interface_for_networks(3):
    print "Wifi SSID:" + singleWifi.get_ssid()
    print "Wifi Network Type:" + singleWifi.get_network_type()

# Add network configuration to wpa_supplicant 

configpath = dave.add_network(sample_network_cfg,3)

# Attach and Select your network (will need to setip address)
dave.select_network(configpath.get_path(),3)
reactor.stop()
