Python – 获取系统已连接的所有 Wifi 设备

在本文中，我们将了解如何使用系统连接的所有 wifi 网络。 Wi-Fi 是一种无线网络技术，它允许计算机（笔记本电脑和台式机）、移动设备（智能手机和可穿戴设备）以及其他设备（打印机和摄像机）等设备与 Internet 连接。
为此，我们将使用 subprocess 模块。 Python（2.x 和 3.x）中存在的 subprocess 模块用于通过创建新进程来通过Python代码运行新的应用程序或程序。它还有助于获取输入/输出/错误管道以及各种命令的退出代码。
为了获取有关 wifi 设备系统连接到的信息，我们将使用下面给出的命令

subprocess.check_output(['netsh', 'wlan', 'show', 'profiles'])

该命令将以字节格式返回元数据，以获取我们必须解码的网络名称，并对其进行过滤以获得所需的输出。
下面是实现

Python3

# importing subprocess
import subprocess
 
# getting meta data of the wifi network
meta_data = subprocess.check_output(['netsh', 'wlan', 'show', 'profiles'])
 
# decoding meta data from byte to string
data = meta_data.decode('utf-8', errors ="backslashreplace")
 
# splitting data by line by line
# string to list
data = data.split('\n')
 
# creating a list of wifi names
names = []
 
# traverse the list
for i in data:
     
    # find "All User Profile" in each item
    # as this item will have the wifi name
    if "All User Profile" in i :
         
        # if found split the item
        # in order to get only the name
        i = i.split(":")
         
        # item at index 1 will be the wifi name
        i = i[1]
         
        # formatting the name
        # first and last chracter is use less
        i = i[1:-1]
         
        # appending the wifi name in the list
        names.append(i)
 
# printing the wifi names
print("All wifi that system has connected to are ")
print("-----------------------------------------")
for name in names:
    print(name)

输出 ：

All wifi that system has connected to are
