php - Symfony2 模板渲染过程中抛出异常 ("Parameter for route must match "[^/]+ +"to generate a corresponding URL.")

Question

在对象名称中使用反斜杠并希望通过对象 URL 继续操作时，我不断收到以下错误:

模板渲染期间抛出异常(“路由“object_show”的参数“name”必须匹配“[^/]++”(给定“black/white”)才能生成相应的URL.") 在/ObjectBundle/Resources/views/Object/index.html.twig

Controller

/**
 * @Route("/show/{user}/{name}", name="object_show")
 * @Template()
 */
public function showAction($user, $name, Request $request)
{
    $user = $this->getDoctrine()->getRepository('UserBundle:User')
                 ->findBy(['username'=> $user]);
    $object = $this->getDoctrine()->getRepository('ObjectBundle:Object')
                   ->findOneBy(['name' => $name, 'user' => $user]);

    return array('object' => $object);
}

如何允许使用反斜杠作为对象名称并能够生成相应的 URL？

模板

      {% for object in objects %}
        <div class="item" id="object_{{ object.id }}">
            <a href="{{ path('object_show',
                     {'user': object.user.username, 'name' : object.name }) }}">
                <div class="title">{{ object.name }}</div>
            </a>
        </div>

Answer 1

您需要将 ,requirements={"name"=".+"} 部分添加到您的路由定义中。例如:

/**
 * @Route("/show/{user}/{name}", name="object_show", requirements={"name"=".+"})
 * @Template()
 */
public function showAction($user, $name, Request $request)
