我是Laravel/PHP的新手，我找不到错误-IamsonewtoLaravel/PHPandIcantfindtheerror

I have a CRM system designed with Lavarel. What I am trying to do is selecting some contacts, clicking on save button (I have to save before exporting as CSV).

我有一个用Lavarel设计的CRM系统。我要做的是选择一些联系人,点击保存按钮(我必须在导出为CSV之前保存)。

However after that when I click on download button my contacts will not export to CSV and I receive this error:

然而,在我点击下载按钮后,我的联系人将不会导出为CSV,我收到此错误:

Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_ERROR) Call to undefined method Symfony\Component\HttpFoundation\BinaryFileResponse::withCOOKIE() Open: /home/mirjamro/public_html/mr-admin.com/app/filters.php

Symfony \ Component \ Debug \ Exception \ FatalErrorException(E_ERROR)调用未定义的方法Symfony \ Component \ HttpFoundation \ BinaryFileResponse :: withCOOKIE()打开:/home/mirjamro/public_html/mr-admin.com/app/filters.php

Auth::logout(); return Redirect::to(URL::route('AdminShowLogin')); }
if(Auth::check()){
  $ckname=Auth::getRecallerName(); //Get the name of the COOKIE, where remember me expiration time is stored
  $ckval=COOKIE::get($ckname); //Get the value of the COOKIE
  return $response->withCOOKIE(COOKIE::make($ckname,$ckval,1440)); //change the expiration time
}
});

I cant download anything from the server.

我无法从服务器下载任何东西。

    return $response->withCOOKIE(COOKIE::make($ckname,$ckval,1440));

    return Response::make($response)->withCOOKIE(COOKIE::make($ckname,$ckval,1440));
