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：默认：index.html.twig：

Hello {{ name }}!

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

为什么会有所不同？ people_homepage路由为何与第二个（web/app_dev.php/people/）网址不匹配？

但如果我将prefix设置为/，我会得到相同的输出：
web/app_dev.php ->你好Foo！
web/app_dev.php/ ->你好Foo！

如果你看appdevUrlMatcher.php，你会看到类似的东西：

    // 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',);
    }

您可以看到路线/people/与people_homepage不匹配，但会与/people或/people/test

匹配

如果您改变路线的顺序

，那么您正在做的事情会更有意义

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

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

使用此配置，您将拥有：

/people == /people/ ---＆gt; people_homepage2

/people/test ---＆gt; people_homepage

使用默认占位符的symfony2路由
