cookies - 拉拉维尔 5.2 : retrieving a cookie via blade returns null also if cookie is set

Question

我通过 Javascript 设置了 cookie my_cookie

   function createCookie(name, value, days) {
      var expires;
      if (days) {
        var date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires="+date.toUTCString();
      }
      else {
        expires = "";
      }
      document.cookie = name+"="+value+expires+"; path=/";
   }

   ....
   createCookie('my_cookie', 1, 365);
   ....

通过 Chrome Cookie Inspector，我看到 cookie 是用值 1 创建的。

通过 Laravel Blade 我尝试过:

 @if (Cookie::get('my_cookie') !== null) // or Cookie::get('my_cookie') == 1 or Cookie::get('my_cookie') == '1'
      <p>set</p>
 @else
      <p>unset</p>
 @endif

写入unset

 @if (request()->cookie('my_cookie') == '1') // or @if (request()->cookie('my_cookie') == 1)
      <p>set</p>
 @else
      <p>unset</p>
 @endif

结果始终是未设置。

您可以使用

App\Http\Middleware\EncryptCookies 的字段 $ except 满足您的需求。

中间件的代码如下所示

<?php

namespace App\Http\Middleware;

use Illuminate\Cookie\Middleware\EncryptCookies as BaseEncrypter;

class EncryptCookies extends BaseEncrypter
{
  /**
   * The names of the cookies that should not be encrypted.
   *
   * @var array
   */
   protected $except = [
      'my_cookie'
   ];
}

现在您可以使用 Cookie::get('my_cookie') 或 request()->cookie('my_cookie') 来检索它
