我想在Action中取得web目录的各种路径

对于你的需求,Symfony2通过DIC提供了kernel服务,以及request(请求)的封装。

在controller里(在其他地方你可以自行注入kernel,这个服务是HttpKernel库里的一个类:好孩子都喜欢读源代码):

<code>$appRoot = $this->get('kernel')->getRootDir(); // 这里得到的是app目录的绝对路径
// ... 然后你可以再定位到web目录了
</code>
Copy after login

web目录的相对路径?相对什么的路径?不管你的实际需求是什么,sf2给你提供了现成的工具,你可以比对获取相对路径:

<code>use Symfony\Component\Filesystem\Filesystem;
$filesystem = new Filesystem();
$filesystem->makePathRelative($endPath, $startPath); // $endPath相对$startPath的相对路径
</code>
Copy after login

至于网址,你可以通过request获得:

<code>// 在controll里:
$this->getRequest()->getHost(); // 主机名
$this->getRequest()->getHttpHost(); // 带协议的主机名
$this->getRequest()->getRequestUri(); // 请求的路径
</code>
Copy after login

还有很多很多的方法,请自己查看
