Codeigniter Routes regex - 在控制器/方法名称中使用短划线

这也正是我的要求，我使用的是像这样的路线

$route['logued/presse-access'] = "logued/presse_access";

在我之前的项目中，我需要创建300-400个路由规则，其中大多数是由于破折号到下划线的转换。

对于我的下一个项目，我急切地想避免它。我做了一些快速的黑客并测试了它，尽管没有在任何实时服务器中使用过，但它对我有用。请执行下列操作。.

确保系统/应用程序/配置/配置中的subclass_prefix如下所示.php

$config['subclass_prefix'] = 'MY_';

然后在系统/应用程序/库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，您可以像 http://example.com/logued/presse-access 一样自由使用url，它将通过自动将破折号转换为下划线来调用正确的控制器和函数。

编辑：以下是我们的Codeigniter 2解决方案，它覆盖了新的CI_Router功能：

<?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，必须像 application/core/MY_Router.php一样放置此文件，并确保他具有subclass_prefix在 application/config/config 中定义.php$config['subclass_prefix'] = 'MY_';

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);
}

使用它是为了可以使用控制器目录内的多级子目录，而通常我们可以在控制器文件夹内使用单级子目录，并且可以在url中调用它。如果没有必要，可以删除此代码，但它对正常流没有害处。

升级到CodeIgniter 2后回到这个问题。这是一个比公认的答案更强大的解决方案，因为它可以在CodeIgniter核心更新中幸存下来。

<?php
class MY_Router extends CI_Router
{ 
    public function set_class($class) 
    {
        parent::set_class($this->_repl($class));
    }

    public function set_method($method) 
    {
        parent::set_method($this->_repl($method));
    }

    public function _validate_request($segments)
    {
        if (isset($segments[0]))
            $segments[0] = $this->_repl($segments[0]);
        if (isset($segments[1]))
            $segments[1] = $this->_repl($segments[1]);

        return parent::_validate_request($segments);
    }

    private function _repl($s)
    {
        return str_replace('-', '_', $s);
    }
}

应将其另存为 。现在，您可以拥有带有下划线的控制器和方法名称，例如（在文件中），并使用URL引用它们。application/core/MY_Router.phpAbc_Defabc_def.php/abc-def
