Symfony2的默认路由占位

Question

应用程序/配置/ routing_dev.yml：

people: 
    resource: "@myPeopleBundle/Resources/config/routing.yml" 
    prefix: /people 

myPeopleBundle /资源/配置/ routing.yml中：

people_homepage: 
    pattern: /{name} 
    defaults: { _controller: myPeopleBundle:Default:index, name: Foo } 

people_homepage2: 
    pattern:/
    defaults: { _controller: myPeopleBundle:Default:index, name: Bar } 

myPeopleBundle：控制器：DefaultController.php：

... 
public function indexAction($name) { 
    return $this->render('myPeopleBundle:Default:index.html.twig', array('name' => $name)); 
} 
... 

myPeopleBundle：Default：index.html.twig：

Hello {{ name }}! 

---

web/app_dev.php/people ->你好富！
web/app_dev.php/people/ -> Hello Bar！

它为什么不同？ people_homepage路由为什么不匹配第二个（web/app_dev.php/people/）url？

但如果我设置prefix到/我得到的结果相同：
web/app_dev.php ->你好富！
web/app_dev.php/ -> Hello Foo！

如果你看看appdevUrlMatcher.php，你会看到这样的事情：

// people_homepage 
    if (preg_match('#^/people(?:/(?P<name>[^/]++))?$#s', $pathinfo, $matches)) { 
     return $this->mergeDefaults(array_replace($matches, array('_route' => 'people_homepage')), array ( '_controller' => 'Acme\\DemoBundle\\Controller\\DefaultController::indexAction', 'name' => 'Foo',)); 
    } 

    // people_homepage2 
    if (rtrim($pathinfo, '/') === '/people') { 
     if (substr($pathinfo, -1) !== '/') { 
      return $this->redirect($pathinfo.'/', 'people_homepage2'); 
     } 

     return array ( '_controller' => 'Acme\\DemoBundle\\Controller\\DefaultController::indexAction', 'name' => 'Bar', '_route' => 'people_homepage2',); 
    } 

你可以看到，该路线/people/不能有不匹配people_homepage，但它会随着/people或/people/test

因为你正在做的事情会更有意义，如果你改变路线的顺序

people_homepage2: 
    pattern:/
    defaults: { _controller: myPeopleBundle:Default:index, name: Bar } 

people_homepage: 
    pattern: /{name} 
    defaults: { _controller: myPeopleBundle:Default:index, name: Foo } 

有了这个配置，你将有：

/people == /people/ --->people_homepage2

/people/test --->people_homepage
