CodeIgniter路由文件夹错误

在CodeIgniter3它不允许您在$route['default_controller']上有一个子文件夹，您需要创建一个MY_Router.php文件，如下所示。

您需要在中创建一个MY_Router.php

application > core > MY_Router.php

下面是一个MY_Router.php文件，它应该允许您在Codeigniter 3 中使用$route['default_controller'] = 'public/pubweb';

<?php
class MY_Router extends CI_Router {
    protected function _set_default_controller() {
        if (empty($this->default_controller)) {
            show_error('Unable to determine what should be displayed. A default route has not been specified in the routing file.');
        }
        // Is the method being specified?
        if (sscanf($this->default_controller, '%[^/]/%s', $class, $method) !== 2) {
            $method = 'index';
        }
        // This is what I added, checks if the class is a directory
        if( is_dir(APPPATH.'controllers/'.$class) ) {
            // Set the class as the directory
            $this->set_directory($class);
            // $method is the class
            $class = $method;
            // Re check for slash if method has been set
            if (sscanf($method, '%[^/]/%s', $class, $method) !== 2) {
                $method = 'index';
            }
        }
        if ( ! file_exists(APPPATH.'controllers/'.$this->directory.ucfirst($class).'.php')) {
            // This will trigger 404 later
            return;
        }
        $this->set_class($class);
        $this->set_method($method);
        // Assign routed segments, index starting from 1
        $this->uri->rsegments = array(
            1 => $class,
            2 => $method
        );
        log_message('debug', 'No URI present. Default controller set.');
    }
}

确保文件名和类名的大小写都是第一个字母。Pubweb.php和class Pubweb extends CI_Controller {}

希望这能有所帮助！

您可以在主控制器文件夹中创建一个新文件用于路由。例如，我有一个类似'controllers/coming/Commingsoon.php'的目录结构。如果我想运行Commingsoon作为我的默认控制器，那么我会这样做：

在控制器文件夹中创建新文件：Main_controller.php:

class Main_controller extends CI_Controller{
    public function __construct(){
        parent:: __construct();
    }
    public function index(){    
        redirect('comming'); 
    }
} 

和在routes.php文件中：

$route['default_controller'] = 'main_controller';
$route['comming'] = 'comming/commingsoon/index';

希望这会有所帮助。。。
