Laravel 5.1 Cookie::get () 无法获取到数据， $_COOKIE 正常

laravel 5.1.34
前端使用
https://github.com/js-cookie/js-cookie

Cookies.set('name', 'value');

后端

namespace App\Http\Controllers;

use Cookie;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class Test extends Controller
{
    public function index(Request $request)
    {
        Cookie::get('name');        // null
        $request->cookie('name');   // null
        $_COOKIE['name'];           // 'value'
        setcookie('orgi', 2);       // success
        $response->withCookie(cookie('laravel', 5));    // not value
        return $response;
    }

哪里错了吗？
