python实现获取外网IP并发邮件的方法

第一步：通过ip138来爬取外网ip

第二步：通过python的smtplib模块和email来发送邮件，具体用法去网上搜索，

下面是代码示例：

#!/usr/bin/env python
#coding:utf-8
 
import urllib2
import re
import smtplib
from email.MIMEText import MIMEText
from email.Header import Header
 
##########################################
#get ip address
url = "http://1212.ip138.com/ic.asp"
url_op = urllib2.urlopen(url)
url_content = url_op.read()
ip_content = re.findall(r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}',url_content)
ipcode = ''.join(ip_content)
 
#################################################
# Setting mail-server, etc
mail_host="smtp.sina.com"
mail_user="ckl"
mail_pass="woXXXX"
mail_postfix="sina.com"
 
#################################################
def send_mail(to_list, sub, content):
 me = mail_user + "<" + mail_user + "@" + mail_postfix + ">"
 msg = MIMEText(content)
 msg['Subject'] = sub
 msg['From'] = me
 msg['To'] = ";".join(to_list)
 
 try:
  s = smtplib.SMTP()
  s.connect(mail_host)
  s.login(mail_user, mail_pass)
  s.sendmail(me, to_list, msg.as_string())
  s.close()
  return True
 except Exception, e:
  print str(e)
  return False
 
#################################################
# Main process
if __name__ == "__main__":
 mailto_list=["41145XXXX@qq.com"]
 
 if send_mail(mailto_list, "你的最新IP地址", ipcode):
  print "Send success!"
 else:
  print "Send failed!"
