一、如：http://127.0.0.1/Home/Index/index.html 会变成：http://www.0.0.1/Home/Index/index.html（这是不需要看到的）
二、开启二级域名时，就不能 生成 一级域名
三、多级域名生成
解决一、在U方法判断$domain是否为"localhost"时 加上正则判断是否为ip访问
解决二、也是判断$domain是否为"localhost"时，否则就是直接生成了www开始的域名， 然后再后面 子域名生成规则中循环判断是否要生成子域名 进行了www替换为配置的子域名
下面是我的处理方法 如果要生成 www.****.com域名 这属于子域名配置
