Yii2 根据所选语言更改 Controller 和 Action 名称

Question

是否可以使用当前选择的语言更改 Controller 名称和操作名称，例如:

如果当前语言是 en 那么 url shuold:

http://localhost/yii2app/site/index

如果当前语言是 da 那么 url 应该:

http://localhost/yii.../websted/indeks

It is what I have tried but it shows 404 not found:

前端/配置/main.php

'urlManager' => [
        'baseUrl' => $baseUrl,
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'rules' => [
            Yii::t('app','site/index') => Yii::t('app','site/index'),
        ],
 ],

在 common/messages/da/app.php

 return [
         'site/index'=>'websted/indeks'
 ];

在我的 layouts/main.php 中

  <a href="<?= Yii::$app->urlManager
                  ->createUrl([Yii::t('app','site/index')])?>">
      <?= Yii::t('app','Home') ?>
  </a>

我已经修改了 Yii 论坛中的这段代码以适用于当前的框架版本。它需要进行测试，因为我很确定其中并未涵盖所有情况。

通用\组件\UrlManager.php:

<?php

namespace common\components;

use Yii;
use yii\web\Request;
use yii\web\UrlManager as YiiUrlManager;

/**
 * UrlManager
 * Allows to translate urls dynamically.
 */
class UrlManager extends YiiUrlManager
{
    public $enablePrettyUrl = true;
    public $showScriptName  = false;

    public $language;

    /**
     * Translated controllers names.
     * language code => [
     *      source name => translated name
     * ]
     * @var array 
     */
    public $languageControllers = [
        'eo' => [
            'site'  => 'ejo',
            'users' => 'uzantoj'
        ],
    ];

    /**
     * Translated actions names.
     * language code => [
     *      source name => translated name
     * ]
     * @var array 
     */
    public $languageActions = [
        'eo' => [
            'contact' => 'kontakton',
            'about'   => 'pri-ni',
            'test'    => 'testo'
        ],
    ];

    /**
     * Initializes UrlManager.
     */
    public function init()
    {
        parent::init();

        if (empty($this->language)) {
            $this->language = Yii::$app->language;
        }
    }

    /**
     * Creates translated url.
     * @param array $params
     * @return string the created URL
     */
    public function createUrl($params)
    {
        $params = (array)$params;

        $route = explode('/', trim($params[0], '/'));
        if (isset($route[0]) && !empty($this->languageControllers[$this->language][$route[0]])) {
            $route[0] = $this->languageControllers[$this->language][$route[0]];
        }
        if (isset($route[1]) && !empty($this->languageActions[$this->language][$route[1]])) {
            $route[1] = $this->languageActions[$this->language][$route[1]];
        }
        $params[0] = implode('/', $route);

        return parent::createUrl($params);
    }

    /**
     * Translates the request back to the source one.
     * @param Request $request the request component
     * @return Request
     */
    public function translateRequest($request)
    {
        if (empty($this->languageControllers[$this->language])) {
            return $request;
        }
        $url = ltrim($request->getPathInfo(), '/');
        $parts = explode('/', $url);
        $controller = $parts[0];
        $action = isset($parts[1]) ? $parts[1] : null;
        foreach ($this->languageControllers[$this->language] as $default => $localized) {
            if ($localized == $controller) {
                $controller = $default;
                break;
            }
        }
        $parts[0] = $controller;
        if ($action !== null) {
            foreach ($this->languageActions[$this->language] as $default => $localized) {
                if ($localized === substr($action, 0, mb_strlen($localized, 'UTF-8'))) {
                    $action = $default . substr($action, mb_strlen($localized, 'UTF-8'));
                    break;
                }
            }
            $parts[1] = $action;
        }
        $request->setPathInfo(implode('/', $parts));
        return $request;
    }

    /**
     * Parses and translates the user request.
     * @param Request $request the request component
     * @return array|boolean the route and the associated parameters. The latter is always empty
     * if [[enablePrettyUrl]] is false. False is returned if the current request cannot be successfully parsed.
     */
    public function parseRequest($request)
    {
        return parent::parseRequest($this->translateRequest($request));
    }
}

网址管理器配置:

// ...
'components' => [
    // ...
    'urlManager' => [
        'class' => 'common\components\UrlManager',
        // ...
    ],
],

现在，对于 Yii:$app->language = 'eo';

1. /site/test 调用带有 Action 测试的 Controller 站点。
2. /ejo/testo 使用 Action 测试调用 Controller 站点。
3. /ejo 使用操作索引调用 Controller 站点。
4. /site/testo 使用 Action 测试调用 Controller 站点。

对于不同的语言，只有现有的路线才有效。您可以以正常方式将参数发送到操作。
