在laravel的构造函数中使用会话值

我一直坚持在_构造函数中使用会话值，但它显示空值。我还在kernel.php中添加了一些配置，但仍然不起作用。请帮忙

public function __construct()
{
    /** PayPal api context **/
    $this->middleware(function ($request, $next) {
        $paypal_conf = \Config::get('paypal');
        $orgId=Session::get('org_id');
        $org_credentials=PaypalCredentials::where('org_id','=',orgId)->first();
        $credentials=$org->paypalCredentials;
        $this->_api_context = new ApiContext(new OAuthTokenCredential(
            $credentials->client_id,
            $credentials->client_secret));
        $this->_api_context->setConfig($paypal_conf['settings']);  

       return $next($request);
 });


}

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Session\Middleware\StartSession::class,
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
];

我们需要更多的信息来提供帮助。在正常情况下，如果这是一个web路由，并且设置了

org\u id

，并且会话cookie传递正确，那么您的代码应该可以工作。我们无法合理地知道您提供的信息量在这种情况下有什么问题。也不要在每个路由中启动会话。会话在api路由中没有意义

    public function __construct()
    {
        /** PayPal api context **/
        $this->middleware(function ($request, $next) {
            $paypal_conf = \Config::get('paypal');
            $orgID = $this->getSession('org_id');

            $org_credentials=PaypalCredentials::where('org_id','=',orgId)->first();
            $credentials=$org->paypalCredentials;
            $this->_api_context = new ApiContext(new OAuthTokenCredential(
                $credentials->client_id,
                $credentials->client_secret));
            $this->_api_context->setConfig($paypal_conf['settings']);  

           return $next($request);
     });


    }

private function getSession(){

            return \Session::get('org_id');

}
