Question

我正在使用Symfony 1.2.7。我的网站有多种语言，每种语言都在en.example.com，es.example.com这样的子域中。如果用户进入example.com，我想将他重定向到他的语言。我还想支持staging.example.com并重定向到es.staging.example.com和en.staging.example.com，这样我就可以在部署之前测试所有内容。

我有以下代码在index.php和frontend_dev.php上都有效。我的问题是，你能提高吗？有更好或更清洁的方式吗？谢谢！

require_once(dirname(__FILE__).'/../config/ProjectConfiguration.class.php');

$configuration = ProjectConfiguration::getApplicationConfiguration('frontend', 'dev', true);
$context = sfContext::createInstance($configuration);

// get the domain parts as an array
$host = array_reverse(explode('.', $_SERVER['HTTP_HOST']));
list($tld, $domain, $subdomain) = $host;

// determine which subdomain we're looking at
$app = ($subdomain == 'staging') ? $subdomain2=$host[3] : $subdomain;

if(empty($app) || $app == 'www')
{
  $browser_languages = $context->getRequest()->getLanguages();

  foreach($browser_languages as $language)
  {
    $allowed_culture = in_array($language, sfConfig::get('app_languagesAvailable'));
    if($allowed_culture)
    {
      $domain = $subdomain ? $subdomain.'.'.$domain : $domain;
      $url = 'http://'.str_replace($domain.'.'.$tld, $language.'.'.$domain.'.'.$tld, $_SERVER['HTTP_HOST']).$_SERVER['REQUEST_URI'];

      $context->getController()->redirect($url);
      break;
    }
  }
}

$context->dispatch();

更新解决方案：自定义过滤器

<?php

class subdomainFilter extends sfFilter
{
    public function execute($filterChain)
    {
        $context = $this->getContext();
        $user = $this->getContext()->getUser();
        $request = $this->getContext()->getRequest();

        // get the domain parts as an array
        $host = array_reverse(explode('.', $request->getHost()));
        list($tld, $domain) = $host;
        $subdomain2 = $host[3];
        $subdomain = $host[2];

        // determine which subdomain we're looking at
        $app = ($host[2] == 'staging') ? $subdomain2 : $subdomain;

        if(empty($app) || $app == 'www')
        {
          // if first time
          if ($this->isFirstCall())
          {
            $browser_languages = $request->getLanguages();
            // set default lang, for API as CURL doesn't set the language
            $lang = sfConfig::get('app_default_culture');

            foreach($browser_languages as $language)
            {
              $allowed_culture = in_array($language, sfConfig::get('app_languagesAvailable'));
              if($allowed_culture)
              {
                $lang = $language;
                break;
              }
            }
          }else {
            // Get user culture
            $lang = $user->getCulture();
          }

          $domain = $subdomain ? $subdomain.'.'.$domain : $domain;
          $url = str_replace($domain.'.'.$tld, $lang.'.'.$domain.'.'.$tld, $request->getURI());
          $context->getController()->redirect($url);
        }

        $filterChain->execute();
    }
}

使用Symfony的路由系统是解决这类问题的正确方法。

看一看 http://www.symfony-project.org/jobeet/1_2/Doctrine/en/05 用于一般路由信息和 http://www.symfony-project.org/blog/2009/03/02/call-the-expert-adding-subdomain-requirements-to-routing-yml 用于高级路由问题。

注意：我强烈建议更新到sf 1.4，因为不再维护1.2。（http://www.symfony-project.org/tutorial/1_4/en/upgrade）
