    说明

如果你想在自己家里搭建一个网站折腾，可以看看本文。由于家庭宽带IP地址总是发生变化，因此需要需要使用动态DNS服务，目前在linux下最好用的还是dnspod，简洁、接口开放、稳定。
准备

在dnspod.cn上注册一个帐号，是免费的，很好用。
写脚本

在其他网站上找到的别人的各种语言的更新dns代码都是只能支持一个子域名，很奇怪，难道支持多域名是我个性化的需求吗？而且dnspod的api每次是覆盖更新，所以不能使用多个脚本来更新。
于是把代码做了一些调整支持同时更新多个子域名。现在只需要修改以下代码行即可增加多个子域名:
ddns_domains = {"*":1111111, "@":222222, "www":3333333};
* 标识泛域名解析，可以解析你所有的子域名，如 aaa.kongwu.net aaa.kongwu.net …xxx.kongwu.net
@ 表示默认域名，比如 kongwu.net 这是我比较喜欢的用法
这里的1111111表示的是这个子域名的record_id， 如何获得record_id呢？
curl -k https://dnsapi.cn/Domain.List -d "login_email=dnspod_user&login_password=dnspod_pwd"
在xml文件中找到domain_id
domain_id = 12345678
curl -k https://dnsapi.cn/Record.List -d "login_email=dnspod_user&login_password=dnspod_pwd&domain_id=12345678"
然后在显示的xml中找到record_id对应的值。
最后，见下面的代码[https://gist.github.com/kennyz/0afc809baabd8223fddf#file-pypod-py] 。
运行脚本

用以下命令运行脚本
/usr/bin/python /home/pi/bin/pypod.py >/home/pi/pypod.log
也可以把它加入到crontab中去（每5分钟自动更新一次）:
*/5 * * * * /usr/bin/python  /home/pi/bin/pypod.py > /home/pi/logs/pypod.log
好了，大功告成，到dnspod的界面上看你更新过的ip吧
