定义的路线丢失 - Cakephp 3.4 中缺少路线

Question

我正在尝试使用前缀 "student"。当我在模板或布局文件中创建 link 时，出现此错误，如图所示：

routes.php

中的代码

    <?php
use Cake\Core\Plugin;
use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;
use Cake\Routing\Route\DashedRoute;

Router::defaultRouteClass(DashedRoute::class);

Router::scope('/', function (RouteBuilder $routes) {
    $routes->connect('/', ['controller' => 'Pages', 'action' => 'display', 'home']);
    $routes->connect('/pages/*', ['controller' => 'Pages', 'action' => 'display']);
    $routes->fallbacks(DashedRoute::class);
});


Router::prefix('admin', function ($routes) {
   $routes->connect('/users/', [ 'controller' => 'MyUsers', 'action' => 'index', 'plugin'=>false]);
   $routes->connect('/login', [ 'controller' => 'MyUsers', 'action' => 'login', 'plugin'=>false, 'prefix'=>'admin']);
   $routes->connect('/', [ 'controller' => 'MyUsers', 'action' => 'dashboard', 'plugin'=>false]);
     $routes->fallbacks(DashedRoute::class);
});

Router::prefix('trainer', function ($routes) {
   $routes->connect('/users/', [ 'controller' => 'MyUsers', 'action' => 'index', 'plugin'=>false]);
   $routes->connect('/login', [ 'controller' => 'MyUsers', 'action' => 'login', 'plugin'=>false]);
   $routes->connect('/', [ 'controller' => 'MyUsers', 'action' => 'dashboard', 'plugin'=>false]);
     $routes->fallbacks(DashedRoute::class);
});


Router::prefix('student', function ($routes) {
   $routes->connect('/courses/', array ( 'controller' => 'Courses', 'action' => 'index', 'plugin' => false, 'prefix' => 'student', '_ext' => NULL, ));
   $routes->connect('/', array ( 'controller' => 'MyUsers', 'action' => 'dashboard', 'plugin' => false));
});

/**
 * Load all plugin routes.  See the Plugin documentation on
 * how to customize the loading of plugin routes.
 */
Plugin::routes();

布局文件student.ctp只有一行代码：

<li><?php echo $this->Html->link('Courses', [ 'controller' => 'Courses', 'action' => 'index', 'plugin' => false, 'prefix' => 'student', '_ext' => NULL, ]);?></li>

AppController.php:

    <?php

namespace App\Controller;

use Cake\Controller\Controller;
use Cake\Event\Event;
use  Cake\Core\Configure;
use Cake\Network\Exception\NotFoundException;




class AppController extends Controller
{

    public $helpers = array(
        'CakeDC/Users.AuthLink',
        'CakeDC/Users.User',
        );


    public function initialize()
    {
        parent::initialize();

        $this->loadComponent('RequestHandler');
        $this->loadComponent('Flash');
        $this->loadComponent('CakeDC/Users.UsersAuth');
        $this->loadComponent('Utils.GlobalAuth');

         $this->Auth->config('loginRedirect', array('controller'=>'Courses', 'action'=>'index', 'plugin'=>FALSE));
         $this->Auth->config('logoutRedirect', array('controller'=>'MyUsers', 'action'=>'login', 'plugin'=>FALSE));
         $this->Auth->config('unauthorizedRedirect', array('controller'=>'Courses', 'action'=>'index', 'prefix'=>$this->Auth->user('role')));
        $this->Auth->config('loginAction', array('controller'=>'MyUsers', 'action'=>'login'));  
         $this->Auth->allow(['login', 'logout']);



    }


    public function beforeRender(Event $event)
    {
        if (!array_key_exists('_serialize', $this->viewVars) &&
            in_array($this->response->type(), ['application/json', 'application/xml'])
        ) {
            $this->set('_serialize', true);
        }

        $this->_renderLayout();
    }

    private function _renderLayout()
    {
        $prefix =  isset($this->request->params['prefix'])?$this->request->params['prefix']:FALSE;

        if(!$prefix)
        {
            return;
        }

       $this->viewBuilder()->setLayout($prefix);



    }





}

我检查了这个解决方案：

您不能为特殊的 plugin 键提供布尔值，它必须是 null 或带有插件名称的字符串。

连接路由时也不需要定义plugin或prefix键，Router::prefix()方法将负责添加前缀。类似地 Router::plugin() 将添加插件名称，当不使用 Router::plugin() 时，plugin 键默认为 null。

进一步定义 _ext 和 null 仅当您不想生成带有扩展名的 URL 时才有意义。并在生成 URLs 时指定它仅当它被定义为非 null 值时才需要，对于 plugin 键也是如此（除非你需要突破当前插件上下文）。

长话短说，连接路线只需要controller和action键：

$routes->connect('/courses/', [
    'controller' => 'Courses',
    'action' => 'index'
]);

并且生成 URL 只需要额外的 prefix 键，如果不在插件上下文中使用，plugin 是可选的：

$this->Html->link('Courses', [
    'controller' => 'Courses',
    'action' => 'index',
    'plugin' => null,
    'prefix' => 'student'
]);
