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 al
