laravel auth如何?的

//\app\Http\Controllers\Auth\AuthController.php/**     * Create a new authentication controller instance.     *     * @param \Illuminate\Contracts\Auth\Guard     $auth     * @param \Illuminate\Contracts\Auth\Registrar $registrar     */    public function __construct(Guard $auth, Registrar $registrar,Request $request)    {        $this->auth = $auth;        $this->registrar = $registrar;        $this->request = $request;        }            public function postRegister()    {        $data = $this->request->all();        //調用App\Services\Registrar裡的validator        $validator = $this->registrar->validator($data);        if ($validator->fails()) {            $this->throwValidationException(                $this->request, $validator            );        }        $this->auth->login($this->registrar->create($data));//這裡的login哪裡實現的？                return redirect('/user');    }    //\app\Providers\AppServiceProvider.php    public function register()    {    //綁定實現Illuminate\Contracts\Auth\Registrar介面的類App\Services\Registrar,但沒綁定auth的        $this->app->bind(            'Illuminate\Contracts\Auth\Registrar',            'App\Services\Registrar'        );    }    

回複內容：

//\app\Http\Controllers\Auth\AuthController.php/**     * Create a new authentication controller instance.     *     * @param \Illuminate\Contracts\Auth\Guard     $auth     * @param \Illuminate\Contracts\Auth\Registrar $registrar     */    public function __construct(Guard $auth, Registrar $registrar,Request $request)    {        $this->auth = $auth;        $this->registrar = $registrar;        $this->request = $request;        }            public function postRegister()    {        $data = $this->request->all();        //調用App\Services\Registrar裡的validator        $validator = $this->registrar->validator($data);        if ($validator->fails()) {            $this->throwValidationException(                $this->request, $validator            );        }        $this->auth->login($this->registrar->create($data));//這裡的login哪裡實現的？                return redirect('/user');    }    //\app\Providers\AppServiceProvider.php    public function register()    {    //綁定實現Illuminate\Contracts\Auth\Registrar介面的類App\Services\Registrar,但沒綁定auth的        $this->app->bind(            'Illuminate\Contracts\Auth\Registrar',            'App\Services\Registrar'        );    }    

Login哪裡實現
\Illuminate\Auth\Guard 第430行

public function login(UserContract $user, $remember = false)    {        $this->updateSession($user->getAuthIdentifier());        // If the user should be permanently "remembered" by the application we will        // queue a permanent cookie that contains the encrypted copy of the user        // identifier. We will then decrypt this later to retrieve the users.        if ($remember) {            $this->createRememberTokenIfDoesntExist($user);            $this->queueRecallerCookie($user);        }        // If we have an event dispatcher instance set we will fire an event so that        // any listeners will hook into the authentication events and run actions        // based on the login and logout events fired from the guard instances.        $this->fireLoginEvent($user, $remember);        $this->setUser($user);    }

還有啥問題麼= =？
