我有列last_activity,其中写入日期最后一个活动用户使用中间件.我如何检查在线用户以及何时注销？
中间件：
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);
}
}
用户模型中的代码：
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(),我需要在其他用户上显示在线用户..但是Auth :: check()检查用户是否只为当前的auth用户保留帐户..
解决方法:
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);
}
}
