从另一个控制器服务访问控制器服务会抛出异常

Question

我在bundle services.xml文件中设置了3个简单的控制器，如下所示：

http://symfony.com/schema/dic/services/services-1.0.xsd">

<parameters>
    <parameter key="wsh_lapi.content.class">Wsh\LapiBundle\Controller\ContentController</parameter>
    <parameter key="wsh_lapi.users.class">Wsh\LapiBundle\Controller\UserController</parameter>
    <parameter key="wsh_lapi.alerts.class">Wsh\LapiBundle\Controller\AlertController</parameter>
</parameters>

<services>
    <service id="wsh_lapi.content" class="%wsh_lapi.content.class%">
        <argument type="service" id="service_container"/>
    </service>
    <service id="wsh_lapi.users" class="%wsh_lapi.users.class%">
        <argument type="service" id="service_container"/>
    </service>
    <service id="wsh_lapi.alerts" class="%wsh_lapi.alerts.class%">
        <argument type="service" id="service_container"/>
    </service>
</services>

<parameters> <parameter key="wsh_lapi.content.class">Wsh\LapiBundle\Controller\ContentController</parameter> <parameter key="wsh_lapi.users.class">Wsh\LapiBundle\Controller\UserController</parameter> <parameter key="wsh_lapi.alerts.class">Wsh\LapiBundle\Controller\AlertController</parameter> </parameters> <services> <service id="wsh_lapi.content" class="%wsh_lapi.content.class%"> <argument type="service" id="service_container"/> </service> <service id="wsh_lapi.users" class="%wsh_lapi.users.class%"> <argument type="service" id="service_container"/> </service> <service id="wsh_lapi.alerts" class="%wsh_lapi.alerts.class%"> <argument type="service" id="service_container"/> </service> </services>

但是当我尝试在AlertController中获取wsh_lapi.users服务时，如下所示：

class AlertController extends Controller { protected $container;

function __construct(Container $container)
{
    $this->container = $container;
}

public function postAlert($appIdToken, $securityToken, $searchParams)
{
    // first let see if user not allready registered
    $em = $this->getDoctrine()->getManager();
    //$user = $this->container->get('wsh_lapi.users')->getUser($appIdToken, $securityToken);
    if($this->container->has('wsh_lapi.users')) {
        // this throws FatalErrorExecption
        $userService = $this->container->get('wsh_lapi.users');
    }
    // check if that alert does not exist allready
    $alertRepo = $em->getRepository('WshLapiBundle:Alert');
    // todo: do checking

    // create new alert object
    $alert = new Alert();
    $alert->setUser($user);
    $alert->setSearchQueryParams($searchParams);
    $em->persist($alert);
    $em->flush();

    return $alert;

}

我收到一个奇怪的错误：

FatalErrorException：错误：在/Users/bard/Projects/LavelAPI/src/Wsh/LapiBundle/Controller/UserController.php第82行中找不到类'Symfony \ Component \ Debug \ Exception \ ContextErrorException'

我不知道该怎么办，第82行是UserController的结尾，看起来像这样：

function __construct(Container $container) { $this->container = $container; } public function postAlert($appIdToken, $securityToken, $searchParams) { // first let see if user not allready registered $em = $this->getDoctrine()->getManager(); //$user = $this->container->get('wsh_lapi.users')->getUser($appIdToken, $securityToken); if($this->container->has('wsh_lapi.users')) { // this throws FatalErrorExecption $userService = $this->container->get('wsh_lapi.users'); } // check if that alert does not exist allready $alertRepo = $em->getRepository('WshLapiBundle:Alert'); // todo: do checking // create new alert object $alert = new Alert(); $alert->setUser($user); $alert->setSearchQueryParams($searchParams); $em->persist($alert); $em->flush(); return $alert; }

}

class UserController extends Controller { protected $container;

事实证明，问题是在我的wsh_lapi.users服务控制器中使用了“getUser”函​​数的名称。可能是与Symfony基本控制器的某种冲突。在我简单地更改功能名称后，它开始工作。
