云博客例如wordpress.com 绑定域名的功能是如何实现的?
例如 wordpress.com 或Tumblr 一个用户注册后可以绑定到自己的一个顶级域名,
这个功能是如何实现的? 因为要做一个类似的云博客,
不知道是在apache或nginx配置里面实现?,
apache如何读取数据库的域名信息然后跳转到对应的用户ID下面的站点?
同时PHP程序中的路由如何实现?

首先你需要知道什么是“泛解析”。
泛解析: *.wordpress.com , 这样的话不管你是1024.wordpress.com ,还是chromefans.wordpress.com,都可以按照 *.wordpress.com解析到wordpress.com
然后在程序判断这个“ * ”就可以了。类似
//伪代码 $var = explode('.', $_SERVER['SERVER_NAME']); $var[0]
上面说的是子域名方法。
下面说的是顶级域名方法。
其实顶级域名也是一样的,不管怎么样让他CNAME绑到你的IP就好了,判断来路域名,去数据库查。
//伪代码 $current = $_SERVER['SERVER_NAME']; if($current != "wordpress.com") { // 当前来路域名不是你的域名 is_user_bind_domain($current); // 是不是用户绑定的 call_something(); }
