如何在Laravel 5.2中使用Cookie [英] How to work with cookies in Laravel 5.2

问题描述

我正在为某些点击事件设置Cookie.然后在将值存储在Cookie中后，我要

I'm setting cookie on some click event. Then after storing value in cookie, I want to

1. 检查cookie是否存在
2. 获取cookie值

我已经通过引用Laravel官方文档开发了一个功能.控制台显示已设置cookie.但是在那之后，我无法解决视图(刀片模板)的两点(在上面的列表中提到).它始终显示(Cookie::get('cookie.clients'))'null'.但是浏览器控制台会显示该Cookie . 如果有人知道答案，将不胜感激.

I have developed a function by referring Laravel official docs. Console shows that cookies have been set. But after that, I can not solve two point (mentioned in above list) for view(Blade Template). It always shows (Cookie::get('cookie.clients')) 'null'. But browser console displays that cookie . If anyone knows answer, it will be appreciated.

这是我的代码.

控制器

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');
    }
}

查看

@if (Cookie::get('cookie.clients') != null)
<p>cookie is set</p>
@else
<p>cookie isn't set</p>
@endif

推荐答案

您正在创建一个cookie对象，但没有将其与响应一起发送.

You're creating a cookie object but you're not sending it with the response.

您可以将其直接添加到控制器中的响应中

You can either, add it directly to your response in a controller

$cookie = Cookie::forever('cookie.clients', $clients);

return redirect('/client')->withCookie($cookie);

或者您可以将Cookie排队并使用 AddQueuedCookiesToResponse 将其自动添加到响应的中间件.

Or you can queue a cookie and use the AddQueuedCookiesToResponse Middleware to automatically add it to the Response.

Cookie::queue(Cookie::forever('cookie.clients', $clients));

return redirect('/client');
