Cookies Laravel 5:自定义中间件设置的cookie在控制器中不可读

我用Laravel 5创建了一个网站。为了跟踪其他网站引用的用户，我使用以下中间件，该中间件通过请求参数识别引用并设置cookie

<?php

namespace App\Http\Middleware;

use Closure;

class AffiliateTrackingMiddleware {

    public static $trackingCookieName = "refId";
    public static $trackingURLParameter = "refId";

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next) {
        $response = $next($request);

        if ($request->has(\App\Http\Middleware\AffiliateTrackingMiddleware::$trackingURLParameter)) {

            return $response->withCookie(cookie()->forever(\App\Http\Middleware\AffiliateTrackingMiddleware::$trackingCookieName, $request->get(\App\Http\Middleware\AffiliateTrackingMiddleware::$trackingURLParameter)));
        }

        return $response;
    }
}

现在奇怪的是，在我的控制器的构造函数中，我能够通过cookie检索正确的附属id。但是，当我从控制器的另一个函数中调用函数

getAffiliateId

时，cookie值保持为空

为什么我无法从控制器中的任何函数检索中间件中设置的cookie值

在我的浏览器中，我还可以看到cookie

先谢谢你

添加：Http/Kernel.php的代码

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel {
    /**
     * The application's global HTTP middleware stack.
     *
     * These middleware are run during every request to your application.
     *
     * @var array
     */
    protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
        \App\Http\Middleware\TrimStrings::class,
        \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
        \App\Http\Middleware\AfterMiddleware::class,
        \App\Http\Middleware\AffiliateTrackingMiddleware::class,
    ];

    /**
     * The application's route middleware groups.
     *
     * @var array
     */
    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            // \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

    /**
     * The application's route middleware.
     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    ];
}

由于您希望在
web
中间件内部使用中间件，请将中间件附加到
web
组中间件的端，如下所示：

'web' => [
    ...
    \App\Http\Middleware\AffiliateTrackingMiddleware::class,
]

另外，请确保当请求到达您的中间件时，您的cookie不是空的
显示您的
内核。php
code我在我的原始帖子中添加了代码。您的中间件看起来不错，并且正确地添加到
内核中。你能给我们看看控制器中的
getAffiliateId
的工作和不工作版本的代码吗？我添加了以下代码
$this->affiliateID=$this->getAffiliateId（$request）
（带或不带参数）在
函数uu-construct（）
内，或在由Route
Route:：group（['middleware'=>['web']，'domain'=>env（“MY_-URL”）]调用的函数
公共函数索引（Request$Request）
内（['middleware'=>['web']，'domain'=>env（“MY_-URL”）]，函数（）{Route:：get（'/'，'MyController@index'); } );
所以你想在
web
中间件调用中使用你的中间件，当你在控制器构造函数中而不是在任何控制器函数中访问它时，它就工作了？太好了。现在可以了！现在cookie也被加密了。你说的“确保你的cookie不是空的…”是什么意思？没关系，我还以为你在检查cookie和url参数呢？现在cookie和url参数都可以用了。谢谢。
'web' => [
    ...
    \App\Http\Middleware\AffiliateTrackingMiddleware::class,
]
