用python来控制wifi连接

1、python连接WiFi，需要使用pywifi包，安装pywifi：pip install pywifi

2、判断wifi连接状态：

def wifi_connect_status():
    wifi = pywifi.PyWiFi()
    iface = wifi.interfaces()[0] #acquire the first Wlan card,maybe not

    if iface.status() in [const.IFACE_CONNECTED,const.IFACE_INACTIVE]:
        print("wifi connected!")
        return 1
    else:
        print("wifi not connected!")
    
    return 0

2、扫描wifi：

def scan_wifi():
    wifi = pywifi.PyWiFi()
    iface = wifi.interfaces()[0]

    iface.scan()
    time.sleep(1)
    basewifi = iface.scan_results()

    for i in basewifi:
        print("wifi scan result:{}".format(i.ssid))
        print("wifi device MAC address:{}".format(i.bssid))
        
    return basewifi

3、连接指定的wifi：

# Define interface status.
IFACE_DISCONNECTED = 0
IFACE_SCANNING = 1
IFACE_INACTIVE = 2
IFACE_CONNECTING = 3
IFACE_CONNECTED = 4

# Define auth algorithms.
AUTH_ALG_OPEN = 0
AUTH_ALG_SHARED = 1

# Define auth key mgmt types.
AKM_TYPE_NONE = 0
AKM_TYPE_WPA = 1
AKM_TYPE_WPAPSK = 2
AKM_TYPE_WPA2 = 3
AKM_TYPE_WPA2PSK = 4
AKM_TYPE_UNKNOWN = 5

# Define ciphers.
CIPHER_TYPE_NONE = 0
CIPHER_TYPE_WEP = 1
CIPHER_TYPE_TKIP = 2
CIPHER_TYPE_CCMP = 3
CIPHER_TYPE_UNKNOWN = 4

# KEY_TYPE_NETWORKKEY = 0
# KEY_TYPE_PASSPHRASE = 1

def connect_wifi():
    wifi = pywifi.PyWiFi()
    ifaces = wifi.interfaces()[0]
    print(ifaces.name())               #输出无线网卡名称
    ifaces.disconnect()
    time.sleep(3)

    profile = pywifi.Profile()                          #配置文件
    profile.ssid = "123_wifi"                           #wifi名称
    profile.auth = const.AUTH_ALG_OPEN                  #需要密码
    profile.akm.append(const.AKM_TYPE_WPA2PSK)          #加密类型
    profile.cipher = const.CIPHER_TYPE_CCMP             #加密单元
    profile.key = "88888888"                            #wifi密码

    ifaces.remove_all_network_profiles()                #删除其它配置文件
    tmp_profile = ifaces.add_network_profile(profile)   #加载配置文件
    ifaces.connect(tmp_profile)
    time.sleep(5)
    isok = True

    if ifaces.status() == const.IFACE_CONNECTED:
        print("connect successfully!")
    else:
        print("connect failed!")

    time.sleep(1)
    return isok
