add pusher private-encrypted #263

[it-can]

Ok added support for private-encrypted channels (#263) (only for Pusher). Hope this is correct.. I don't use Ts a lot...

Seems to be good.

@taylorotwell note that this is to support laravel/framework#31559

[taylorotwell]

@it-can did you actually build this and test it in a local application using npm link?

[it-can]

@taylorotwell yes I just tested this. works perfectly.

In Laravel set in the config/broadcasting.php file, a base64 encoded masterkey.

'pusher' => [
            'driver'  => 'pusher',
            'key'     => env('PUSHER_APP_KEY'),
            'secret'  => env('PUSHER_APP_SECRET'),
            'app_id'  => env('PUSHER_APP_ID'),
            'options' => [
                        'useTLS'       => true,
                        'cluster'      => 'eu',
                        'encryption_master_key_base64' => 'mysecretbase64encodedkey',
            ],
        ],

Broadcast to a EncryptedPrivateChannel channel.

namespace App\Events;

use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Broadcasting\EncryptedPrivateChannel;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class CalenderRefresh implements ShouldBroadcast
{
    use InteractsWithSockets, SerializesModels;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return Channel|array
     */
    public function broadcastOn()
    {
        return new EncryptedPrivateChannel('calendar');
    }
}

Subscribe with Echo to a privateEncrypted channel

Echo.privateEncrypted('calendar').listen('CalenderRefresh', function () {
            reloadCalendar();
        });

This works for me

One thing I notice is a mismatch between backend and frontend. On backend we say "EncryptedPrivate" but on this we say "privateEncrypted"... I would change it to "encryptedPrivate" here in Echo so it matches.

yeah I also noticed it... Pusher uses private-encrypted... But I guess changing the naming in Laravel is a breaking change... I'll change my PR

@taylorotwell ok renamed it

[taylorotwell]

Released Echo 1.7.0 on NPM.
