就像这里说的那样,我已经覆盖了FOSUserBundle的layout.html.twig模板.

<div>
{% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}

app.user.username}, 'FOSUserBundle') }} |

{{ 'layout.logout'|trans({}, 'FOSUserBundle') }}

trans({}, 'FOSUserBundle') }}</a>

在Symfony2中,服务被定义为[强调我的]:
服务是执行特定任务的任何PHP对象的通用术语.服务通常" 全局 "使用,例如数据库连接对象或传递电子邮件消息的对象.在Symfony2中,通常从服务容器配置和检索服务.据说具有许多解耦服务的应用程序遵循面向服务的体系结构.
以"全局"为关键词,我看到的如何定义服务的所有示例都在现有的bundle中声明了服务?以下是MartinSikora.com的一个例子
<?php
// Bundle/HelloBundle/Services/MyService.php
namespace Bundle\HelloBundle\Services;
class MyService {
public function sum($n1, $n2) {
return $n1 + $n2;
}
}

然后他在Hello Controller中使用它:
<?php
// Bundle/HelloBundle/Controller/HelloController.php
namespace Bundle\HelloBundle\Controller;
class HelloController extends Controller {
public function indexAction() {
$number = $this->get('my_service')->sum(12, 37);
// this returns 49

}
}

请注意他的示例服务如何在标记为"Services"的文件夹中的HelloBundle包内声明.如果"Services"文件夹存储在任何特定捆绑包之外的一个或多个级别,那是不是更好,因为服务是要在整个应用程序中使用的?
