python获取外网IP并发邮件的实现方法

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!"
