Cakephp 3 带有语言参数的路由答案

【问题描述】：

我正在尝试将 cakephp 2.x 转换为 3.x。我正在使用Router::connect() 规则，但我尝试将它们转换为范围版本。

关于myold的路由规则，我在config/routes.php添加了这个。

  Router::defaultRouteClass('Route');
  Router::scope('/', function ($routes) {

    $routes->connect('/:language/:controller/:action/*', ['language' => 'ar|de|en|fr']);
    $routes->connect('/:language/:controller', ['action' => 'index', 'language' => 'ar|de|en|fr']);
    $routes->connect('/:language', ['controller' => 'Mydefault', 'action' => 'index', 'language' => 'ar|de|en|fr']);

    $routes->redirect('/gohere/*', ['controller' => 'Mycontroller', 'action' => 'myaction'], ['persist' => array('username')]);

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

    $routes->fallbacks('InflectedRoute');
});

但这在example.com/en/works 中失败了。我收到此错误：Error: worksController could not be found. 因为我的控制器文件是WorksController.php。

控制器名称部分是否挂在句子 casein cakephp 3 上？ http://book.cakephp.org/3.0/en/intro/conventions.html#controller-conventions

同样example.com/foo/bar 给出此错误：Error: barController could not be found.。但是foo 是控制器，bar 是操作。

如何解决这个路由问题？

编辑：
将Route::defaultRouteClass('Route') 更改为Route::defaultRouteClass('InflectedRoute') 解决了问题1。但问题2 存在。

【问题讨论】：

您的 routes.php 顶部必须有一行 Route::defaultRouteClass('Route')。将其更改为Route::defaultRouteClass('InflectedRoute')。
此修复错误1。但错误2存在。当我输入example.com/foo/bar 时，cakephp 会查找 barController。

【解决方案1】：

诸如路由元素模式之类的选项必须通过Router::connect() 的第三个参数$options 参数传递。

这条路线：

$routes->connect(
    '/:language/:controller',
    ['action' => 'index', 'language' => 'ar|de|en|fr'
]);

将捕获您的/foo/bar URL，它将匹配foo 的:language 元素和bar 的:controller 元素。基本上 URL 数组中的 language 键将被视为默认值，并且它总是会被 :language 元素值覆盖。

定义路线的正确方法是：

$routes->connect(
    '/:language/:controller',
    ['action' => 'index'],
    ['language' => 'ar|de|en|fr']
);

其他路线需要相应调整。

最好的方法是使用路由范围

<?php
$builder = function ($routes) {
    $routes->connect('/:action/*');
};
$scopes = function ($routes) use ($builder) {
    $routes->scope('/questions', ['controller' => 'Questions'], $builder);
    $routes->scope('/answers', ['controller' => 'Answers'], $builder);
};

$languages = ['en', 'es', 'pt'];
foreach ($languages as $lang) {
    Router::scope("/$lang", ['lang' => $lang], $scopes);
}

Router::addUrlFilter(function ($params, $request) {
    if ($request->param('lang')) {
        $params['lang'] = $request->param('lang');
    }
    return $params;
});

从 CakePHP 3 应用程序框架扩展默认路由器

原始 routes.php 已移除 cmets

<?php

use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;
use Cake\Routing\Route\DashedRoute;

Router::defaultRouteClass(DashedRoute::class);

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

用定义集中的语言修改

<?php

use Cake\Routing\RouteBuilder;
use Cake\Routing\Router;
use Cake\Routing\Route\DashedRoute;

Router::defaultRouteClass(DashedRoute::class);

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

// support only for 3 languages, other language will throw 404/NotFoundException
// or will cause different routing problem based on your routes
Router::scope('/', $routerCallback);
foreach (["en", "fr", "de"] as $language) {
    Router::scope('/' . $language, ['language' => $language], $routerCallback);
}

// to access the language param, or default to 'en', use 
// $this->request->getParam('language', 'en')
// from AppController, PagesController, etc...

rooter.php

$routes->connect('/:lang/:controller/:action',[],[ 'lang' => '[a-z]{2}','pass' => ['lang']]);
$routes->connect('/:lang/', ['controller' => 'Pages', 'action' => 'index'],[ 'lang' => '[a-z]{2}','pass' => ['lang']]); 
$routes->connect('/:lang/index', ['controller' => 'Pages', 'action' => 'index'],[ 'lang' => '[a-z]{2}','pass' => ['lang']]); 
$routes->connect('/:lang/pages/*', ['controller' => 'Pages', 'action' => 'index'],[ 'lang' => '[a-z]{2}','pass' => ['lang']]);
$routes->connect('/:lang/contact', ['controller' => 'Pages', 'action' => 'contact'],[ 'lang' => '[a-z]{2}','pass' => ['lang']]);
$routes->connect('/:lang/about', ['controller' => 'Pages', 'action' => 'about'],[ 'lang' => '[a-z]{2}','pass' => ['lang']]);

类应用控制器公共函数 beforeFilter(Event $event) { $this->Auth->allow(['']);

    if(isset($this->request->params['pass'][0]))
    $lang = $this->request->params['pass'][0];
    else $lang = 'en';
    I18n::locale($lang);

}
