获取所有连接的用户(Laravel 5) [英] Get All Connected Users (Laravel 5)

问题描述

如何显示我家中所有已连接的用户?

How to display all connected users in my home?

推荐答案

这是一种非常基本的方法，但希望能有效地检测Laravel5应用程序中的Guest和Registered用户.

This is a very basic, but hopefully an efective way to detect both Guest and Registered users on your Laravel5 application.

第1步

打开文件config/session.php，并将驱动程序更改为数据库.

Open the file config/session.php and change the driver to database.

第2步

我们需要创建会话表，因此请使用以下工匠命令php artisan session:table生成迁移文件.

We need to create the sessions table, so use the following artisan command php artisan session:table to generate the migration file.

第3步

在此新生成的迁移中，您需要添加一个新的user_id列，这样我们可以将会话与用户相关联(如果该用户已登录).

On this newly generated migration, you need to add a new user_id column, this is so we can relate the session to a user, if that user is logged in of course.

打开文件migrations/xxxx_xx_xx_xxxxxx_create_session_table.php，然后在Schema :: create中添加以下内容:

Open the file migrations/xxxx_xx_xx_xxxxxx_create_session_table.php and add the following inside the Schema::create:

$t->integer('user_id')->nullable();

这是完整迁移的外观:

<?php

use Illuminate\Database\Migrations\Migration;

class CreateSessionTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('sessions', function($t) 
        {
            $t->string('id')->unique();
            $t->text('payload');
            $t->integer('last_activity');
            $t->integer('user_id')->nullable();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('sessions');
    }

}

第4步

运行composer dump-autoload和php artisan migrate.

注意:如果尚未全局安装Composer，则只需使用php composer.phar dump-autoload.

第5步

将Eloquent模型保存为应用程序中的Session.php.

Save the Eloquent Model somewhere on your application as Session.php.

注意:建议将此位置保存在应用程序目录中.

第6步

现在，您只需要知道如何使用它.

Now you just need to know how to use it.

. .

用法

将以下Session::updateCurrent();放置在代码中，因为这将确保当前用户的会话条目已更新，仅作为示例，您可以将其放置在app/routes.php文件中.

Place the following Session::updateCurrent(); somewhere on your code, as this will make sure that the session entry for the current user get's updated, just an example, you can place it on your app/routes.php file.

获取所有用户(访客+注册)

Get all users (Guests + Registered)

$all = Session::all();

如果您需要在一定时期内(例如10分钟)在线检查所有用户，则需要调用activity(:limit)方法，如下所示:

If you need to check all users online for a certain period, like 10 minutes, you need to call the activity(:limit) method, like so:

$all = Session::activity(10)->get();

注意:此方法可以与guest()和/或registered()方法结合使用.

Note: This method can be used in combination with the guests() and/or registered() methods.

访客用户

全部获取

$guests = Session::guests()->get();
Get the # of Guest users

$total = Session::guests()->count();

注册用户

全部获取

$registered = Session::registered()->get();

foreach ($registered as $online) {
    // You can retrieve the user information using something like:
    var_dump($online->user->email);
}

获取注册用户数

$total = Session::registered()->count();

口才模式:

use Carbon\Carbon;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Session;
use Illuminate\Database\Eloquent\Builder;
use Cartalyst\Sentinel\Laravel\Facades\Sentinel;

class Session extends Model 
{
    /**
     * {@inheritdoc}
     */
    public $table = 'sessions';

    /**
     * {@inheritdoc}
     */
    public $timestamps = false;

    /**
     * Returns the user that belongs to this entry.
     *
     * @return \Cartalyst\Sentinel\Users\EloquentUser
     */
    public function user()
    {
        return $this->belongsTo('Cartalyst\Sentinel\Users\EloquentUser');
    }

    /**
     * Returns all the users within the given activity.
     *
     * @param  \Illuminate\Database\Eloquent\Builder  $query
     * @param  int  $limit
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeActivity($query, $limit = 10)
    {
        $lastActivity = strtotime(Carbon::now()->subMinutes($limit));

        return $query->where('last_activity', '>=', $lastActivity);
    }

    /**
     * Returns all the guest users.
     *
     * @param  \Illuminate\Database\Eloquent\Builder  $query
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeGuests(Builder $query)
    {
        return $query->whereNull('user_id');
    }

    /**
     * Returns all the registered users.
     *
     * @param  \Illuminate\Database\Eloquent\Builder  $query
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeRegistered(Builder $query)
    {
        return $query->whereNotNull('user_id')->with('user');
    }

    /**
     * Updates the session of the current user.
     *
     * @param  \Illuminate\Database\Eloquent\Builder  $query
     * @return \Illuminate\Database\Eloquent\Builder
     */
    public function scopeUpdateCurrent(Builder $query)
    {
        $user = Sentinel::check();

        return $query->where('id', Session::getId())->update([
            'user_id' => $user ? $user->id : null
        ]);
    }
}

或者，您也可以尝试此.

Alternatively you can try this.
