Code:

tig_blobuploader_blobuploader:    path: /blobuploader    defaults: { _controller: tig.blobuploader.controller.blobuploader::handle_request }    methods: [POST]

Code:

services:...    tig.blobuploader.controller.blobuploader:        class: tig\blobuploader\controller\blobuploader        arguments:            - '@user'            - '@request'            - '%core.root_path%'            - '%core.php_ext%'

Code:

<?phpnamespace tig\blobuploader\controller;use Symfony\Component\HttpFoundation\Response;class blobuploader{    protected $user;    protected $request;    protected $root_path;    protected $php_ext;    public function __construct(        user $user,        request $request,        $root_path,        $php_ext    ) {        $this->user = $user;        $this->request = $request;        $this->root_path = $root_path;        $this->php_ext = $php_ext;    }    public function handle_request ()    {        ...     }
