检查用户是否在线laravel [英] Check if user online laravel

问题描述

我有last_activity列，其中写有上次活动的用户和中间件的日期.
如何检查在线用户以及何时注销?

I have column last_activity, where write date last activity user with middleware.
How I can check online user and when he logout?

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()-不起作用.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()检查用户是否仅保留当前身份验证用户的帐户.

$user->check => Auth::check() - not working. I don't need use Auth::check(), I need show online user on other users.. But Auth::check() check if user stay in account only for current auth user..

推荐答案

<?php

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);
    }
}
