Python gets the current public network ip and automatically disconnects the broadband connection instance code

Today, I wrote a file to get the current public network ip and automatically disconnect the broadband connection, and I will share it with you.

The specific purpose of this file is clear and you can use it, but it only applies to the Windows platform at present. My VERSION of Python is 2.7, and the win32ras module needs to download pywin32.

The code is as follows:

#!coding: cp936 
import win32ras 
import time,os 
 
def Connect(dialname, account, passwd): 
  dial_params = (dialname, '', '', account, passwd, '') 
  return win32ras.Dial(None, None, dial_params, None) 
 
def DialBroadband(): 
  dialname = ' A broadband connection ' #just a name 
  account = '********' 
  passwd = '****************' 
  try: 
    #handle is a pid, for disconnect or showipadrress, if connect success return 0. 
    #account is the username that your ISP supposed, passwd is the password. 
    handle, result = Connect(dialname, account, passwd) 
    if result == 0: 
      print "Connection success!" 
      return handle, result 
    else: 
      print "Connection failed, wait for 5 seconds and try again..." 
      time.sleep(5) 
      DialBroadband()   
  except: 
    print "Can't finish this connection, please check out." 
    return 
 
def Disconnect(handle): 
  if handle != None: 
    try: 
      win32ras.HangUp(handle) 
      print "Disconnection success!" 
      return "success" 
    except: 
      print "Disconnection failed, wait for 5 seconds and try again..." 
      time.sleep(5) 
      Disconnect() 
  else: 
    print "Can't find the process!" 
    return 
 
def Check_for_Broadband(): 
  connections = [] 
  connections = win32ras.EnumConnections() 
  if(len(connections) == 0): 
    print "The system is not running any broadband connection." 
    return 
  else: 
    print "The system is running %d broadband connection." % len(connections) 
    return connections 
 
def ShowIpAddress(handle): 
  print win32ras.GetConnectStatus(handle) 
  data = os.popen("ipconfig","r").readlines() 
  have_ppp = 0 
  ip_str = None 
  for line in data: 
    if line.find(" A broadband connection ")>=0: 
      have_ppp = 1 
    #if your system language is English, you should write like this: 
    #if have_ppp and line.strip().startswith("IP Address"): 
    #in othewords, replace the "IPv4  address " to "IP Address" 
    if have_ppp and line.strip().startswith("IPv4  address "): 
      ip_str = line.split(":")[1].strip() 
      have_ppp = 0 
      print ip_str 
 
#get my ipaddress anf disconnect broadband connection. 
def main(): 
  data = Check_for_Broadband() 
  #if exist running broadband connection, disconnected it. 
  if data != None: 
    for p in data: 
      ShowIpAddress(p[0]) 
      if(Disconnect(p[0]) == "success"): 
        print "%s has been disconnected." % p[1] 
      time.sleep(3) 
  else: 
    pid, res = DialBroadband() 
    ShowIpAddress(pid) 
    time.sleep(3) 
    Disconnect(pid) 
  return "finsh test" 
 
test = main() 
print test 

There are basic notes, you can refer to their own.
