我正在为某些点击事件设置cookie.然后在cookie中存储值后,我想
>检查是否存在cookie
>获取cookie值
我通过参考Laravel官方文档开发了一个函数.控制台显示已设置cookie.但在那之后,我无法解决视图(Blade Template)中的两点(在上面的列表中提到).它总是显示(Cookie :: get(‘cookie.clients’))’null’.但浏览器控制台显示该cookie
.
如果有人知道答案,我们将不胜感激.
这是我的代码.
调节器
use App\Client;
use App\Http\Requests;
use Illuminate\Http\Request;
use Validator;
use App\Http\Controllers\Controller;
use App\Repositories\ClientRepository;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Cookie;
class ClientController extends Controller
{
public function cookieadd(Request $request,Client $client)
{
$clients = [];
if (Cookie::get('cookie.clients') != null)
{
$clients = Cookie::get('cookie.clients');
}
array_push($clients,$client);
Cookie::forever('cookie.clients',$clients);
return redirect('/client');
}
}
视图
@if (Cookie::get('cookie.clients') != null)
<p>cookie is set</p>
@else
<p>cookie isn't set</p>
@endif
您正在创建一个cookie对象,但是您没有通过响应发送它.
您可以将其直接添加到控制器中的响应中
$cookie = Cookie::forever('cookie.clients',$clients);
return redirect('/client')->withCookie($cookie);
或者您可以对cookie进行排队并使用AddQueuedCookiesToResponse中间件自动将其添加到响应中.
Cookie::queue(Cookie::forever('cookie.clients',$clients));
return redirect('/client');
