在我的Symfony2项目中集成FOSfacebookBundle后，我在尝试执行我的项目时得到这个错误:
An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "fos_facebook_channel" as such route does not exist.") in MyBundle::layout.html.twig at line 32.
第32行:
{{ facebook_initialize({'xfbml': true, 'fbAsyncInit': 'onFbInit();'}) }}
我刚刚检查了fo_facebook_channel是否在文件FOS/FacebookBundle/Resources/config/routing.xml中有路由，它确实有:
<route id="fos_facebook_channel" pattern="/channel.html">
<default key="_controller">FOSFacebookBundle:Facebook:channel</default>
<requirement key="_method">GET</requirement>
</route>
尝试添加
fos_facebook_channel:
resource: "@FOSFacebookBundle/Resources/config/routing.xml"
到appconfigrouting.yml文件
