 4.pywifi详细教程

 5.后言

 6.原本教程（英文版）

 二、pywifi的介绍与下载  

1.介绍：pywifi是在python中一个用于操作无线接口的模块，可以跨平台使用，Windows和Linux都支持

2.下载：①pip下载：打开命令提示符，输入下载命令：

pip install pywifi

由于此模块基于comtypes模块，因此同时需要下载此模块：

pip install comtypes

对于PyCharm，则直接下载两个模块即可

三、pywifi基础  

#  引入pywifi库及所带常量库
import pywifi
from pywifi import const, Profile

#  1. 基础

#  获取网卡接口
wifi = pywifi.PyWiFi()

#  得到第一个无线网卡
ifaces = wifi.interfaces()[0]

#  切断网卡连接
ifaces.disconnect()

#  获取wifi的连接状态
wifistatus = ifaces.status()

#  检查wifi是否处于切断状态
if wifistatus == const.IFACE_DISCONNECTED:

    #  网卡已被切断

    pass

#  如果网卡没有被切断
#  或者使用 " if wifistatus == const.IFACE_CONNECTED: "

else:

    #  已连接wifi

    pass

#  如果已经切断网卡，一般执行下述操作
if wifistatus == const.IFACE_DISCONNECTED:

    #  设置wifi连接文件
    profile: Profile = pywifi.Profile()

    #  你要连接的网络的名称
    profile.ssid = "    "

    #  网卡的开放状态
    #  " Auth - AP "的验证算法
    profile.auth = const.AUTH_ALG_OPEN

    #  wifi的加密算法
    #  通常的加密算法值为 " WPA "
    #  选择wifi的加密方式
    #  " Akm - AP "的密钥管理
    profile.akm.append(const.AKM_TYPE_WPA2PSK)

    #  加密单元
    #  " Cipher - AP "的密码类型
    profile.cipher = const.CIPHER_TYPE_CCMP

    #  设置密码
    password = "   "

    #  回调密码（wifi密码）
    #  如果没有密码，则设置值为 " CIPHER_TYPE_NONE "
    profile.key = password

    #  删除已连接的所有wifi文件
    ifaces.remove_all_network_profiles()

    #  加载新的wifi连接文件
    tep_profile = ifaces.add_network_profile(profile)

    #  连接上面的wifi文件
    ifaces.connect(tep_profile)

    #  如果wifi已连接
    if ifaces.status() == const.IFACE_CONNECTED:

        print(True)

    #  如果仍未连接
    else:

        print(False)

四、pywifi详细讲解  

#  2.提高

#  获取wifi接口名称
name = ifaces.name()

#  扫描wifi ( AP )
ifaces.scan()

#  查看上面的wifi扫描结果 ( 返回值为列表 )
result = ifaces.scan_results()

#  删除所有的AP配置文件
#  目的是为了接下来的连接
ifaces.remove_all_network_profiles()

#  返回配置文件的列表
files = ifaces.network_profiles()

#  设置配置文件的名字
ifaces.add_network_profile(profile)

#  连接wifi
ifaces.connect(profile)

#  断开wifi
ifaces.disconnect()

#  wifi的连接状态
ifaces.status()

#  配置文件
profile = pywifi.Profile()

#  配置文件的方法
#  ssid  auth  akm  cipher  key
#  这些的详细讲解可看基础


#  pywifi中const的量

#  const.IFACE_DISCONNECTED = 0
#  const.IFACE_SCANNING = 1
#  const.IFACE_INACTIVE = 2
#  const.IFACE_CONNECTING = 3
#  const.IFACE_CONNECTED = 4

#  Auth - AP
var1 = const.AUTH_ALG_OPEN
var2 = const.AUTH_ALG_SHARED

#  Akm - AP
#  不安全的方法
var3 = const.AKM_TYPE_NONE
#  WPA的方法
var4 = const.AKM_TYPE_WPAPSK
#  WPA2的方法
var5 = const.AKM_TYPE_WPA2PSK
#  对于企业的方法
var6 = const.AKM_TYPE_WPA
var7 = const.AKM_TYPE_WPA2

#  Cipher - AP
var8 = const.CIPHER_TYPE_NONE  
var9 = const.CIPHER_TYPE_WEP
var10 = const.CIPHER_TYPE_TKIP
var11 = const.CIPHER_TYPE_CCMP

六、原本教程（英文版）  

#  Import the module of PyWifi
import pywifi
from pywifi import const, Profile

#  1. Basic

#  Get the network card interface
wifi = pywifi.PyWiFi()

#  Get the first wireless network card
ifaces = wifi.interfaces()[0]

#  Disconnect the network card
ifaces.disconnect()

#  Get the connection state of wifi
wifistatus = ifaces.status()

#  Check if disconnect the wifi
if wifistatus == const.IFACE_DISCONNECTED:

    #  The network card disconnect

    pass

#  If the network card has already connected
#  Or use the " if wifistatus == const.IFACE_CONNECTED: "

else:

    #  Have already connected the wifi

    pass

#  If you have already disconnect the network card, do the below
if wifistatus == const.IFACE_DISCONNECTED:

    #  Set up the file of wifi connection
    profile: Profile = pywifi.Profile()

    #  The name of wifi which you want to connect
    profile.ssid = "TP-LINKwangqing"

    #  The opening state of the network card
    #  The authentication algorithm of " Auth - AP"
    profile.auth = const.AUTH_ALG_OPEN

    #  The encryption algorithm of wifi
    #  The encryption algorithm of common wifi is " WPA "
    #  Choose the encryption way of wifi
    #  The key management type of " Akm - AP "
    profile.akm.append(const.AKM_TYPE_WPA2PSK)

    #  Encryption unit
    #  The password type of " Cipher - AP "
    profile.cipher = const.CIPHER_TYPE_CCMP

    #  Set the password
    password = "wangzijia123456"

    #  Call the password ( the password of wifi)
    #  If there's no password, set the value " CIPHER_TYPE_NONE "
    profile.key = password

    #  Delete all the file of wifi which has already connected
    ifaces.remove_all_network_profiles()

    #  Loading the new file of connection
    tep_profile = ifaces.add_network_profile(profile)

    #  Connect the new file that above
    ifaces.connect(tep_profile)

    #  If the wifi has already connected
    if ifaces.status() == const.IFACE_CONNECTED:

        print(True)

    #  If it has disconnected yet
    else:

        print(False)



#  2.Improvement

#  Get the name of wifi interface
name = ifaces.name()

#  Scan the wifi ( AP )
ifaces.scan()

#  Look the result of scanning ( list )
result = ifaces.scan_results()

#  Delete all the setting files of AP
#  In order to the next connect
ifaces.remove_all_network_profiles()

#  Return the list of setting files
files = ifaces.network_profiles()

#  Set the name of setting file
ifaces.add_network_profile(profile)

#  Connect the wifi
ifaces.connect(profile)

#  Disconnect the wifi
ifaces.disconnect()

#  The connection state of wifi
ifaces.status()

#  Const in pywifi

#  const.IFACE_DISCONNECTED = 0
#  const.IFACE_SCANNING = 1
#  const.IFACE_INACTIVE = 2
#  const.IFACE_CONNECTING = 3
#  const.IFACE_CONNECTED = 4

#  Set up the file
profile = pywifi.Profile()

#  The way to set up the file
#  ssid  auth  akm  cipher  key
#  These look above

#  Auth - AP
var1 = const.AUTH_ALG_OPEN
var2 = const.AUTH_ALG_SHARED

#  The mode of WPA
var4 = const.AKM_TYPE_WPAPSK
#  The mode of WPA2
var5 = const.AKM_TYPE_WPA2PSK
#  For business
var6 = const.AKM_TYPE_WPA
var7 = const.AKM_TYPE_WPA2

#  Cipher - AP
var8 = const.CIPHER_TYPE_NONE  
var9 = const.CIPHER_TYPE_WEP
var10 = const.CIPHER_TYPE_TKIP
var11 = const.CIPHER_TYPE_CCMP
