备注：
此脚本使用起来很灵活，可以和nagios使用起来也很方便，废话不多说，看实例：
python2.6 check_web_status.py -u yoururl -s yoururl_status(200, 301, 302, 404, 500 ... 都可以)
[xxx@xxx 10:32:47 ]# /usr/bin/python2.6 check_web_status.py -u http://www.8558.com/ -s 200
WEBURL OK: This http://www.8558.com/ state is 200
0 <----为nagios返回0
[xxx@xxx 10:32:47 ]# /usr/bin/python2.6 check_web_status.py -u http://www.8558.com/index.ph -s 200
WEBURL CRITICAL: This http://www.8558.com/index.ph state is 404
2 <----为nagios返回2
解释：-u 参数后面可以加你要监控的网址。
-s 参数后面可以加你要监控网址的状态，如何你监控的状态是301，那么除了301状态，其他的会报警给nagios。
