Detailed explanation of how Laravel uses pusher to push messages

1. Register pusher

1. Register

https:// pusher.com/

2. Get key, secret key, app_id, etc.

2. Configure pusher

1. Install pusher

composer require pusher/pusher-php-server

2. Configure config/broadcasting.php

'default' => env('BROADCAST_DRIVER', 'pusher'),
....
'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_KEY'),
            'secret' => env('PUSHER_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
                'cluster' => 'ap1',
                'encrypted' => true
            ],
        ],
.....

3. Create events

1. The code is as follows:

<?php
 
namespace App\Events;
 
use App\Events\Event;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
 
class PusherEvent extends Event implements ShouldBroadcast
{
    use SerializesModels;
 
    public $info;
 
    /**
     * PusherEvent constructor.
     */
    public function __construct($info)
    {
        $this->info = $info;
    }
 
    /**
     * 指定广播频道(对应前端的频道)
     * Get the channels the event should be broadcast on.
     *
     * @return array
     */
    public function broadcastOn()
    {
        return [&#39;my-channel&#39;];
    }
 
    /**
     * 指定广播事件(对应前端的事件)
     * @return string
     */
    public function broadcastAs()
    {
        return &#39;my-event&#39;;
    }
 
    /**
     * 获取广播数据,默认是广播的public属性的数据
     */
    public function broadcastWith()
    {
        return [&#39;info&#39; => $this->info];
    }
}

2. Broadcast events do not require a listener; broadcast events need to inherit the interface ShouldBroadcast

4. Broadcast

1 .Trigger event

event(new \App\Events\PusherEvent(&#39;测试&#39;));

2. Front-end code

<!DOCTYPE html>
<head>
  <title>Pusher Test</title>
  <script src="https://js.pusher.com/4.0/pusher.min.js"></script>
  <script>
 
    // Enable pusher logging - don&#39;t include this in production
    Pusher.logToConsole = true;
 
    var pusher = new Pusher(&#39;XXX&#39;, {
      cluster: &#39;ap1&#39;,
      encrypted: true
    });
 
    var channel = pusher.subscribe(&#39;my-channel&#39;);
    channel.bind(&#39;my-event&#39;, function(data) {
      alert(data.info);
    });
  </script>
</head>

ps:

1.pusher uses curl to https://pusher. com Submit data, so you need to configure the certificate; otherwise the submission will fail

2. If you do not configure the certificate, you need to set curl’s CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST

#curl_setopt($ch, CURLOPT_POSTFIELDS, $post_value of trigger in vender/pusher/pusher-php-server/lib/Pusher.php );

Added below:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
