连接 WiFi python 的最简单方法

Question

我想使用 python 连接到我的 wifi 网络。 我知道网络的 SSID 和密钥，并且它在 WPA2 安全性中加密。 我见过一些图书馆，比如无线和 pywifi，但第一个没有用，第二个太复杂了。 连接wifi最简单的方法是什么？ 什么是最好的图书馆/方式？

我使用无线库的失败代码（当然，我是通过 pip 安装的）：

from wireless import Wireless

wire = Wireless()
wire.connect(ssid='myhome',password='password')

解释器 output：

Traceback (most recent call last):
File "C:/Users/Aviv/PycharmProjects/Networks/WiFi/1/1.py", line 4, in 
<module>
wire = Wireless()
File "C:\Python27\lib\site-packages\wireless\Wireless.py", line 23, in 
__init__
self._driver_name = self._detectDriver()
File "C:\Python27\lib\site-packages\wireless\Wireless.py", line 50, in

compare = self.vercmp(ver, "0.9.9.0")
File "C:\Python27\lib\site-packages\wireless\Wireless.py", line 71, in vercmp
return cmp(normalize(actual), normalize(test))
File "C:\Python27\lib\site-packages\wireless\Wireless.py", line 70, in 
normalize
return [int(x) for x in re.sub(r'(\.0+)*$', '', v).split(".")]

无需任何模块即可轻松连接 Wifi：

import os


class Finder:
    def __init__(self, *args, **kwargs):
        self.server_name = kwargs['server_name']
        self.password = kwargs['password']
        self.interface_name = kwargs['interface']
        self.main_dict = {}

    def run(self):
        command = """sudo iwlist wlp2s0 scan | grep -ioE 'ssid:"(.*{}.*)'"""
        result = os.popen(command.format(self.server_name))
        result = list(result)

        if "Device or resource busy" in result:
                return None
        else:
            ssid_list = [item.lstrip('SSID:').strip('"\n') for item in result]
            print("Successfully get ssids {}".format(str(ssid_list)))

        for name in ssid_list:
            try:
                result = self.connection(name)
            except Exception as exp:
                print("Couldn't connect to name : {}. {}".format(name, exp))
            else:
                if result:
                    print("Successfully connected to {}".format(name))

    def connection(self, name):
        cmd = "nmcli d wifi connect {} password {} iface {}".format(name,
            self.password,
            self.interface_name)
        try:
            if os.system(cmd) != 0: # This will run the command and check connection
                raise Exception()
        except:
            raise # Not Connected
        else:
            return True # Connected

if __name__ == "__main__":
    # Server_name is a case insensitive string, and/or regex pattern which demonstrates
    # the name of targeted WIFI device or a unique part of it.
    server_name = "example_name"
    password = "your_password"
    interface_name = "your_interface_name" # i. e wlp2s0  
    F = Finder(server_name=server_name,
               password=password,
               interface=interface_name)
    F.run()

我希望你使用的是 Windows 机器。 然后你应该安装winwifi模块。 在安装winwifi模块之前，最好先安装plumbum模块。 尝试将其安装在 python 32 位版本中。

点击这里安装plumbum模块： https : //pypi.org/project/plumbum/

然后安装 winwifi： https ://pypi.org/project/winwifi/

现在您可以尝试使用以下代码连接已知的 wifi：

import winwifi
winwifi.WinWiFi.connect('ssid_of_the_router')

这个模块有更多的命令，比如：

winwifi.WinWiFi.disconnect()

winwifi.WinWiFi.addprofile('ssid_of_new_router') 等

您可以通过浏览我的 github 存储库来检查这一点： https : //github.com/ashiq-firoz/winwifi_Guide

如果您使用的是 Ubuntu/linux，则可以使用本机可用的网络管理器 cli package (nmcli)：

import subprocess

def what_wifi():
    process = subprocess.run(['nmcli', '-t', '-f', 'ACTIVE,SSID', 'dev', 'wifi'], stdout=subprocess.PIPE)
    if process.returncode == 0:
        return process.stdout.decode('utf-8').strip().split(':')[1]
    else:
        return ''

def is_connected_to(ssid: str):
    return what_wifi() == ssid

def scan_wifi():
    process = subprocess.run(['nmcli', '-t', '-f', 'SSID,SECURITY,SIGNAL', 'dev', 'wifi'], stdout=subprocess.PIPE)
    if process.returncode == 0:
        return process.stdout.decode('utf-8').strip().split('\n')
    else:
        return []
        
def is_wifi_available(ssid: str):
    return ssid in [x.split(':')[0] for x in scan_wifi()]

def connect_to(ssid: str, password: str):
    if not is_wifi_available(ssid):
        return False
    subprocess.call(['nmcli', 'd', 'wifi', 'connect', ssid, 'password', password])
    return is_connected_to(ssid)

def connect_to_saved(ssid: str):
    if not is_wifi_available(ssid):
        return False
    subprocess.call(['nmcli', 'c', 'up', ssid])
    return is_connected_to(ssid)

连接到已保存的网络：

connect_to_saved('my_wifi')

否则，使用 ssid 和密码连接到网络：

connect_to('my_wifi', 'my_password')
