Laravel设置cookie不起作用 [英] Laravel set cookie not working

问题描述

我在自定义中间件中有以下代码：

I have the following code in a custom middleware:

public function handle($request, Closure $next)
{
    if($request->hasCookie('uuid')) {
        return $next($request);    
    }

    $uuid = 99;
    $response = $next($request);
    return $response->withCookie(cookie()->forever('uuid', $uuid));

}

我已经在app.php文件中注册了中间件，但cookie仍未写入。任何人都可以帮忙。另外，上述内容可以作为单例运行，以便在应用启动时执行一次吗？

I have registered the middleware in the app.php file, but cookies is still not being written. Please can anyone help. Additionally can this above be run as a singleton, so that it is executed once on app start?

谢谢

推荐答案

在这里，我会在下面的laravel简单示例中提到set并获取一个cookie。

Here, I'm mention set and get a cookie in laravel simple example following.

首先创建一个控制器。

First of the create a controller.

1. php artisan make：controller CookieController

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class CookieController extends Controller {

  **/* below code a set a cookie in browser */**
   public function setCookie(Request $request){
      $response = new Response('Hello World');
      $response->withCookie(cookie('name', 'Anything else'));
      return $response;
   }
  **/* below code a get a cookie in browser */**
   public function getCookie(Request $request){
      $value = $request->cookie('name');
      echo $value;
   }
}

在路线/ web.php文件（Laravel 5.4）

Add a following line code in routes/web.php file (Laravel 5.4)

Route::get('/cookie/set','CookieController@setCookie');   
Route::get('/cookie/get','CookieController@getCookie');

与运行程序相比，所有文件加载项项目都易于设置并获取Cookie。

And all files add-in project than a run program easily sets and get a cookie.
