Redis keyPrefix Problem

• Echo Version: 1.5.3
• Laravel Version: 5.8.*
• PHP Version: 7.2.17
• NPM Version: 6.8.0
• Node Version: 8.10.8

Description:

When Echo used with Redis, it produces keyPrefix to every channel you created. (which is by default “laravel_database_”)

Steps To Reproduce:

1-) Use Redis as Broadcast Driver and Queue Connection

BROADCAST_DRIVER=redis
QUEUE_CONNECTION=redis

2-) Create any Event

class UserRegistered implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }

    public function broadcastOn()
    {
        return new PrivateChannel('test');
    }

    public function broadcastAs()
    {
        return 'user.registered';
    }

    public function broadcastWith()
    {
        return ['id' => $this->user->id];
    }
}

3-) Broadcast this event with Private Channel called ‘test’ 4-) Authorize this channel

Broadcast::channel('test', function ($user) {
    return $user;
});

5-) Initialize Echo in your js file

import Echo from "laravel-echo"

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001',
    authEndpoint: "/broadcasting/auth",
});

6-) Initialize your channel

 Echo.private(`test`)
                .listen('.user.registered', function (e) {
                    console.log(e);
                });

7-) Send event

event(new UserRegistered($user));

😎 See laravel-echo-server logs

[6:13:51 AM] - W3drJJWfqL9OacTmAAAa authenticated for: private-test
[6:13:51 AM] - W3drJJWfqL9OacTmAAAa joined channel: private-test
Channel: foo_bar_database_private-test
Event: user.registered

My Redis keyPrefix is “foo_bar_database_”, so the channel name that the event emitted is “foo_bar_database_private-test” but i am listening the channel “private-test”. So Echo never gets the event.

I tried to delete “private-” prefixes from both php&js side but this time Echo not requiring to authenticate channel anymore since not see as private channel.

I was able to get it working:

In config/database.php disable prefix for redis.

Now i can do

 window.Echo.private('channel')

And in routes/channels.php

Broadcast::channel('channel', function ($user) {

With redis-cli monitor 👍

1558979801.909666 [0 172.20.0.1:35198] "PUBLISH" **"private-channel"** "{\"event\":\"App\\\\Events\\\\PrivateMessage\",\"data\":{\"msg\":\"Hello\",\"user\":\"foo\",\"socket\":\"vDVEap6hCjgJ5OhtAAAB\"},\"socket\":\"vDVEap6hCjgJ5OhtAAAB\"}"

And Echo clients gets their message.

As you’re using Laravel just edit your .env file and set:

REDIS_PREFIX=

This will remove the ‘foo_bar_database_’ prefix from your channel names. Then make sure you’ve restarted your services.
