替换上你的 API Token，域名ID，记录ID等参数，就可以运行了。 会在后台一直运行，每隔30秒检查一遍IP，如果修改了就更新IP。

获取 API Token 的方式

获得 domain_id 可以用 curl

curl -k https://dnsapi.cn/Domain.List -d "login_token=TOKEN"`

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}
