python3练习-发送IP地址到邮箱（使用日志）

看了下python下的logging模块，和java的log4j差不多，把之前的代码改为使用log配置的方式实现功能（需求和之前的相同，地址"http://www.cnblogs.com/GYoungBean/p/6510508.html"）

#! usr/bin/env python3
# -*- coding:utf-8 -*-

import socket
import threading
import logging.config

now_ip = ""

def _get_ip_win():
    ips = socket.gethostbyname_ex(socket.gethostname())
    for s in ips[2]:
        if s.startswith(''):
            return s

def checkIP(start_ip):
    global now_ip
    if start_ip != now_ip:
        logger_mail.error('Send Mail:the old IP is:%s.Now,the new IP is:%s' % (now_ip,start_ip))
        now_ip = start_ip
    else:
        logger_root.info('IP address not change,the old IP is:%s---the new IP is:%s' % (start_ip, now_ip))
    new_ip = _get_ip_win()
    t = threading.Timer(3600.0, checkIP,(new_ip,))
    t.start()

if __name__ == '__main__':
    logging.config.fileConfig("./logging.conf")
    logger_mail = logging.getLogger('mail')
    logger_root = logging.getLogger('root')
    start_ip,now_ip = _get_ip_win(),_get_ip_win()
    checkIP(start_ip)

日志配置如下(logging.conf)：

[loggers]
keys=root,mail

[handlers]
keys=consoleHandler,fileHandler,mailHandler

[formatters]
keys=simpleFormatter

[formatter_simpleFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s - [%(filename)s:%(lineno)s]
datefmt=

[logger_root]
level=INFO
handlers=consoleHandler,fileHandler

[logger_mail]
level=ERROR
handlers=mailHandler,fileHandler
qualname=mail
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=INFO
formatter=simpleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=INFO
formatter=simpleFormatter
args=('./ipchange.log', 'a')

[handler_mailHandler]
class=handlers.SMTPHandler
level=ERROR
formatter=simpleFormatter
args=(('xxx',25), 'xxx', ['xxx','xxx'], 'NOTICE!!!--PC IP CHANGED', ('xxx', 'xxx'))
