问一下大家，关于非LARAVEL默认加密方式登录dingo的$token生成问题

    //登录获取token
    public function login()
    {
        $credentials = request(['email', 'password']);

        if (!$token = auth('api')->attempt($credentials)) {
            return $this->response->errorUnauthorized('帐号或密码错误');
        }

        return $this->respondWithToken($token);
    }Copy

        $ytuser = YtUser::query()->where(['username' => $data['username'], 'password' => $data['password'], 'user_status' => '1'])->first();

        if (is_null($ytuser)) {
            return $this->response->errorUnauthorized('帐号或密码错误');
        }

//以上通过验证，下边怎么成生token，这里怎么写
        $token = auth('api')->？？？？？？;
return $this->respondWithToken($token);Copy

    //获取用户资料
    public function me()
    {
        return response()->json(auth('api')->user());
    }

    //销毁token
    public function logout()
    {
        auth('api')->logout();

        return response()->json(['message' => 'Successfully logged out']);
    }

    //刷新token
    public function refresh()
    {
        return $this->respondWithToken(auth('api')->refresh());
    }

    //响应token
    protected function respondWithToken($token)
    {
        return response()->json([
            'access_token' => $token,
            'token_type'   => 'bearer',
            'expires_in'   => auth('api')->factory()->getTTL() * 60,
        ]);
    }Copy
