最近遇到一个项目要求使用二级域名,以方便SEO,由于采用的是CodeIgniter框架,这个框架虽然提供了灵活的路由功能,但是不能实现二级域名。查询了多很资料之后,经过几番测试得出了解决方法。本例采用www.mysite.com这个假域名。

步骤1:

首先在httpd.conf中建立virtualhost

<VirtualHost *:80>
  ServerAdmin admin@163.com
  DocumentRoot "D:/www/cms"
  ServerName www.mysite.com
  ServerAlias *.mysite.com #这里采用泛解析的方式
  ErrorLog "logs/mysite.com-error.log"
  CustomLog "logs/mysite.com.log" common
</VirtualHost>

步骤2:

我要实现这样的效果:
http://www.mysite.com/category/news/1.html  =====>  http://category.mysite.com/news/1.html
为了确保能正常访问这个domain,必须修改hosts文件

127.0.0.1 www.mysite.com
127.0.0.1 category.mysite.com

步骤3:

修改:system/core/URI.php的_set_uri_string方法

/**
 * Set the URI String
 *
 * @access public
 * @param string
 * @return string
 */
function _set_uri_string($str)
{
 // Filter out control characters
 $str = remove_invisible_characters($str, FALSE);
 // If the URI contains only a slash we'll kill it
 $this->uri_string = ($str == '/') &#63; '' : $str;
 // Add by fengyun for url rewrite at 2013-1-25 1:02:27
 @include(APPPATH.'config/domain'.EXT);
 $arrServerName = explode('.', $_SERVER['SERVER_NAME']);
 if (in_array($arrServerName[0], $domain)) {
 $this->uri_string = '/' . $arrServerName[0]."/" . $this->uri_string;
 }
}

这里主要是为了让URL能正确的被CI理解。

步骤4:在application/config/下建立一个domain.php文件。内容如下:

<&#63;php
if ( ! defined('BASEPATH'))
exit('No direct script access allowed');
$domain = array('category',"detail","info","archive");

至此已经基本完成了,不过,使用site_url()的时候,如果要使用二级域名,就得另做处理了。
