这是laravel中auth\guard的构造函数：
/** * create a new authentication guard. * * @param \illuminate\auth\userproviderinterface $provider * @param \illuminate\session\store $session * @param \symfony\component\httpfoundation\request $request * @return void */ public function __construct(userproviderinterface $provider, sessionstore $session, request $request = null) { $this->session = $session; $this->request = $request; $this->provider = $provider; }

其中传入了参数sessionstore $session
但是session的构造函数是这样的:
public function __construct($name, sessionhandlerinterface $handler, $id = null) { $this->setid($id); $this->name = $name; $this->handler = $handler; $this->metabag = new metadatabag; }

这里是有参数的，为什么guard的构造函数可以自动生成session?
是php原生提供的还是laravel提供的?
