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。

<?php

class 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：

<?php

class 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。
