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!"
以上这篇python获取外网IP并发邮件的实现方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
