如何使用Cake PHP创建子域？ [英] How to create Sub Domains using Cake PHP?

问题描述

我正在建立一个网站，每个设定档都需要一个专属的子网域。我使用的技术是Cake PHP + MongoDB。我需要知道同样的可行性。是否可以创建一个物理DNS或者我可以简单地路由用户的配置文件页面，在Cake PHP中的Routes类的帮助。

I am building a site ,which requires a unique sub-domain for each profile. The technology which I am using is Cake PHP + MongoDB. I need to know the feasibility of the same. Whether I can create a Physical DNS or I can simply route the Profile page of the User , by the help of Routes Class in Cake PHP. Please suggest what will be better and easy way to implement along with feasibility of the same.

感谢进阶。

推荐答案

如果您对每个网站使用CakePHP，则无需担心为每个网站创建多个子域，您只需创建通配符DNS记录即可。这会从服务器和DNS管理中消除很多麻烦。

If you are using CakePHP for each of the websites, you do not need to worry about multiple subdomain creation for each site, you can simply create a wildcard DNS record. This removes a lot of the hassle from the server and DNS administration.

通配符DNS记录（Wiki）

使用通配符DNS记录，您可以使用HTTP_HOST或CakePHP方式， $ request-> host（）来确定用于访问系统的主机名（子域）。然后，您可以在AppController的beforeFilter（）方法中加载正确的配置文件详细信息，然后从那里向前移动。

With the wildcard DNS record in place, you can then use HTTP_HOST, or the CakePHP way, $request->host() to determine the hostname (subdomain) being used to access your system. You can then load the correct profile details in the beforeFilter() method of AppController and move forward from there.

我会执行一些操作：

class User extends AppModel
{
     public $belongsTo = array(
          'Profile'
     );

     public function findByProfileHostname($hostname) {
         return $this->find('first', array('conditions' => array(
             'Profile.hostname' => $hostname
         ));
     }
};

class AppController extends Controller
{
    public function beforeFilter () {
        $this->ActiveUser = $this->User->findByProfileHostname($this->request->host());
        if (!$this->ActiveUser) {
            throw new InvalidArgumentsException(__('%s is not active here', $this->request->host()));
        }
    }
}
