Symfony Basic

• 获取登录用户信息

  • 控制器中

    $this->getUser();

    等价于

     $this->get('security.token_storage')
     ->getToken()
     ->getUser(); 

  • Twig中：

     {% if app.user %}{{ app.user.username }}{% else %}游客{% endif %}

• 用户密码加密

/**
 *
 * @var \Symfony\Component\Security\Core\Encoder\UserPasswordEncoder
 */
$encoder = $this->get('security.password_encoder');

校验密码:

$encoder->isPasswordValid($user, $userForm->getPassword())；

密码加密:

$password = $encoder->encodePassword($user, $userForm->getPlainPassword());

• 文件上传相关

$file = $request->files->get('file'); //获取上传的文件
if($file instanceof UploadedFile){
    //不为空
    $filename = $this->get('kit.file_uploader')->upload($file, 'file');
}else{
    //未上传
}

• 获取根目录和host

$this->getContainer()->get('kernel')->getRootDir()
$root = $this->container->get('kernel')->getRootDir();
$root = $this->get('kernel')->getRootDir();
// xx/xxx/app
//Symfony 3.3
$root = $this->get('kernel')->getProjectDir()
// %kernel.project_dir%
/*
 * use %kernel.project_dir%/web/ instead of %kernel.root_dir%/../web/.
 **/

get HOST

$request()->getHost()

• 获取当前路由名称

// controller
$routeName = $request->get('_route');

{# twig #}
{{ app.request.get('_route') }}

• 获取头部信息

$ua = $request->headers->get('User-Agent');

• 获取referer

$this->getRequest()->headers->get('referer')；
$request->server->get('HTTP_REFERER');
