symfony筆記之--基礎經常使用知識點

Symfony Basic

• 獲取登陸用戶信息

  • 控制器中

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

  • Twig中：

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

• 用戶密碼加密

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

  校驗密碼:

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

  密碼加密:

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

• 文件上傳相關

  $file = $request->files->get('file'); //獲取上傳的文件
     if($file instanceof UploadedFile){
         //不爲空
         $filename = $this->get('kit.file_uploader')->upload($file, 'file');
     }else{
            //未上傳
     }

• 獲取根目錄和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()

• 獲取當前路由名稱

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