慢慢地看清CI了 &&&&& 望高人指教
以下为CI核心类CI_Router类中的一段代码：--------------------------
/**
* Validates the supplied segments.Attempts to determine the path to
* the controller.
*
* @access private
* @param array
* @return array
*/
function _validate_request($segments)
{
// Does the requested controller exist in the root folder?
if (file_exists(APPPATH.'controllers/'.$segments.EXT))
{
return $segments;
}
// Is the controller in a sub-folder?
if (is_dir(APPPATH.'controllers/'.$segments))
{
// Set the directory and remove it from the segment array
$this->set_directory($segments);
$segments = array_slice($segments, 1);
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments.EXT))
{
show_404($this->fetch_directory().$segments);
}
}
else
{
$this->set_class($this->default_controller);
$this->set_method('index');
// Does the default controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
{
$this->directory = '';
return array();
}
}
return $segments;
}
// Can't find the requested controller...
show_404($segments);
}
------------------------------------------------------------------------
这说明什么？ 这说明CI 的控制器类的目录不可以有两级或以上的子目录 ，试了一下，果然不行，提示404。
不知哪位有好点的解决方法。 只能是自己扩展这个类，支持多级目录了。 呵呵，目前还没有用的2级以上的目录，谢谢楼主发现
http://www.jiayuan.com/15284073 CI的周全判断太保守了，想提速只能自己定制CI，改码 看来是 CI 没注意性能问题？
实际上，扩展这个类就可以实现多级目录了，CI 扩展很容易，并且自己扩展的东西，比别人提供的更好把握。 放到 application/libaries/下 MY_Router.php
