我一直在构想可以自定义文章的路径,就像Wp那个别名一样!可惜我又担心和Controller冲突,我就研究了一下源码.但是不知道有没有一个方法类是可以直接验证的.
源码是这样验证的:
PHP复制代码
function _validate_request ($segments)
{
if (count($segments) == 0)
{
return $segments;
}
// Does the requested controller exist in the root folder?
if (file_exists(APPPATH .'controllers/'.$segments[0].EXT ))
{
return $segments;
}
// Is the controller in a sub-folder?
if (is_dir(APPPATH .'controllers/'.$segments[0]))
{
// Set the directory and remove it from the segment array
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);
if (count($segments) > 0)
{
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH .'controllers/'.$this->fetch_directory().$segments[0].EXT ))
{
show_404 ($this->fetch_directory().$segments[0]);
}
}
else
{
// Is the method being specified in the route?
if (strpos($this->default_controller, '/') !== FALSE)
{
$x = explode('/', $this->default_controller);
$this->set_class($x[0]);
$this->set_method($x[1]);
}
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 $segments;
}
// If we've gotten this far it means that the URI does not correlate to a valid
// controller class. We will now see if there is an override
if ( ! empty($this->routes['404_override']))
{
$x = explode('/', $this->routes['404_override']);
$this->set_class($x[0]);
$this->set_method(isset($x[1]) ? $x[1] : 'index');
return $x;
}
// Nothing else to do at this point but show a 404
show_404 ($segments[0]);
}
复制代码
所以其实有没有一个方法类是验证的?我不想重复造轮子!哈哈!
