这也正是我的要求，而且我使用了类似
$route['logued/presse-access'] = "logued/presse_access";
在我之前的项目中，我需要创建300-400路由规则，其中大多数是由于短划线到下划线的转换。
对于我的下一个项目，我热切希望避免。尽管没有在任何实时服务器中使用它，但我已经对其进行了一些快速的修改并对其进行了测试，但是它对我有用。请执行下列操作..
确保您的system / application / config / config.php中的subclass_prefix如下所示
$config['subclass_prefix'] = 'MY_';
然后在system / application / libraries目录中上传一个名为MY_Router.php的文件。
<?phpclass MY_Router extends CI_Router { function set_class($class) { //$this->class = $class; $this->class = str_replace('-', '_', $class); //echo 'class:'.$this->class; } function set_method($method) {// $this->method = $method; $this->method = str_replace('-', '_', $method); } function _validate_request($segments) { // Does the requested controller exist in the root folder? if (file_exists(APPPATH.'controllers/'.str_replace('-', '_', $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().str_replace('-', '_', $segments[0]).EXT)) { show_404($this->fetch_directory().$segments[0]); } } 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[0]); }}现在，您可以自由使用网址，例如http://example.com/logued/presse-
access，它将通过自动将破折号转换为下划线来调用适当的控制器和功能。
编辑： 这是我们的Codeigniter 2解决方案，它将覆盖新的CI_Router函数：
<?phpclass MY_Router extends CI_Router { function set_class($class) { $this->class = str_replace('-', '_', $class); } function set_method($method) { $this->method = str_replace('-', '_', $method); } function set_directory($dir) { $this->directory = $dir.'/'; } function _validate_request($segments) { if (count($segments) == 0) { return $segments; } // Does the requested controller exist in the root folder? if (file_exists(APPPATH.'controllers/'.str_replace('-', '_', $segments[0]).'.php')) { 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); while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0])) { // Set the directory and remove it from the segment array $this->set_directory($this->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().str_replace('-', '_', $segments[0]).'.php')) { if ( ! empty($this->routes['404_override'])) { $x = explode('/', $this->routes['404_override']); $this->set_directory(''); $this->set_class($x[0]); $this->set_method(isset($x[1]) ? $x[1] : 'index'); return $x; } else { show_404($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.'.php')) { $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]); }}现在必须放置该文件，例如application / core /
MY_Router.php，并确保他具有subclass_prefix的定义如
$config['subclass_prefix'] ='MY_';在application / config / config.php中
在方法中添加了几行额外的代码
_validate_request()：
while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0])){ // Set the directory and remove it from the segment array $this->set_directory($this->directory . $segments[0]); $segments = array_slice($segments, 1);}它用于使人可以使用controllers目录内的多层子目录，而通常我们可以在controllers文件夹内使用单层子目录并可以在url中调用它。如果不需要，可以删除此代码，但对正常流程没有危害。
