laravel5.4控制器中的单变量双函数

Question

我使用api，我在indexx函数中使用access_token变量，这是服务器发送的json结果，现在我试图在图片函数中使用这个变量，然后用口香糖将这个变量发送到服务器，我能做什么呢？我的控制器有以下代码：

public function indexx(Request $request)
{
    $code = $this->code = $request->get('code');

    try {
        $client = new Client();
        $res = $client->request  ('POST', 'https://api.instagram.com/oauth/access_token', [
            'form_params' => [
                'client_id' => 'client_id' ,
                'client_secret' =>  'client_secret',
                'grant_type' => 'authorization_code',
                'redirect_uri' => 'http://hanie-asemi.ir/laravel/instagram/test',
                'code' => $code
            ]
        ]);
        $status = $res->getStatusCode();
        if ($status == 200) {
            $body = $res->getBody();
            $obj = \GuzzleHttp\json_decode($body);

            $access_token=$obj->access_token;
            echo view('json')->with($access_token);

        } else {
            echo "status is not 200";
        }

    } catch (BadResponseException $e) {
        echo "error1";
    }

}

public function picture()
{
    $client = new Client();
    $res2 = $client->request  ('GET', 'https://api.instagram.com/v1/users/self/media/recent/?access_token=Access_token');
}

另一种方法是写信给config并从中阅读

public function indexx(Request $request)
{
    ...
    $access_token = $obj->access_token;
    config(['app.access_token' => $access_token]);
    ...
}

public function picture()
{
    $client = new Client();
    $access_token = config('app.access_token', 'fallback token');
    $res2 = $client->request('GET', 'https://api.instagram.com/v1/users/self/media/recent/?access_token='.$access_token);
}
