我找到了一种使用 Symfony 而非 Symfony2 的好方法:http://symfony.com/blog/play-with-the-user-language

推荐答案

我发现的最简单的方法是直接在 twig 模板中进行.至少，它适用于 2.2:

The easiest way I have found is to do it directly in the twig template. At least, it works with 2.2:

<ul class="lang-menu">
  <li><a href="{{ path(app.request.get('_route'), app.request.get('_route_params')|merge({'_locale': 'ca'})) }}">Català</a></li>
  <li><a href="{{ path(app.request.get('_route'), app.request.get('_route_params')|merge({'_locale': 'en'})) }}">English</a></li>
</ul>
