我有列last_activity,其中寫入日期最后一個活動用戶使用中間件.我如何檢查在線用戶以及何時注銷？

中間件：

class LastActivityUser

{

/**

* Handle an incoming request.

*

* @param \Illuminate\Http\Request $request

* @param \Closure $next

* @return mixed

*/

public function handle($request, Closure $next)

{

if (\Auth::check() && (\Auth::user()->last_activity < new \DateTime('-5 minutes'))) {

$user = \Auth::user();

$user->last_activity = new \DateTime;

$user->timestamps = false;

$user->save();

}

return $next($request);

}

}

用戶模型中的代碼：

public function online() {

return ($this->last_activity > new \DateTime('-5 minutes') && $user->check()) ? true : false;

}

$user-> check => Auth :: check() – 不工作.我不需要使用Auth :: check(),我需要在其他用戶上顯示在線用戶..但是Auth :: check()檢查用戶是否只為當前的auth用戶保留帳戶..

解決方法:

namespace App\Http\Middleware;

use Closure;

use Illuminate\Contracts\Auth\Factory as Auth;

class LastActivityUser

{

/**

* The authentication factory instance.

*

* @var \Illuminate\Contracts\Auth\Factory

*/

protected $auth;

/**

* Create a new middleware instance.

*

* @param \Illuminate\Contracts\Auth\Factory $auth

* @return void

*/

public function __construct(Auth $auth)

{

$this->auth = $auth;

}

/**

* Handle an incoming request.

*

* @param \Illuminate\Http\Request $request

* @param \Closure $next

* @return mixed

*/

public function handle($request, Closure $next)

{

if ($this->auth->check() && $this->auth->user()->last_activity < Carbon::now()->subMinutes(5)->format('Y-m-d H:i:s')) {

$user = $this->auth->user();

$user->last_activity = new \DateTime;

$user->timestamps = false;

$user->save();

}

return $next($request);

}

}
