Symfony2如何允许在路由正则表达式中使用破折号? [英] Symfony2 how to allow slug with dashes in routes regex?

问题描述

我的路线(slug 包含破折号！):

My route (slug contains dashes!):

region:
  pattern: /regione/{slug}-{id}
  defaults: { _controller: SWAItaliaInCifreBundle:Default:region }

在 Twig 模板中:

In Twig template:

{% for r in regions %}
    <a href='{{ path('region', { 'slug':r.slug, 'id':r.id }) }}'>{{ r.name }}</a>
{% endfor %}

我收到一个关于正则表达式匹配的错误.问题:为什么 Symfony2 不允许在 url 中使用破折号?我如何指定我的路线包含破折号(并且非常好)?

I'm getting an error about regular expression matching. Question: why Symfony2 does not permit dashes in url? How can i specify that my route contains dashes (and it's perfectly fine)?

在渲染模板期间引发了异常("路由 "region" 的参数 "slug" 必须匹配 "[^/-]+?"(给出valle-d-aosta-vallee-d-aoste").")

An exception has been thrown during the rendering of a template ("Parameter "slug" for route "region" must match "[^/-]+?" ("valle-d-aosta-vallee-d-aoste" given).")

推荐答案

默认情况下禁止使用斜线.您可以通过更改默认要求来启用它们.在您的情况下，最好对 id 提出要求，因为它用破折号分隔.

Slashes are by default forbidden. You can enable them by changing the default requirements. In your case it'd be also good to give requirements for the id as it's separated with dash.

请参阅下面的示例.

region:
    pattern: /regione/{slug}-{id}
    defaults:
        _controller: SWAItaliaInCifreBundle:Default:region
    requirements:
        slug: "[a-zA-Z1-9-_/]+"
        id: "d+"
