Problem with share session.

[KrissMcCone]

Hello I try to share sesssion by this tutorial: https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md

My configuration:

Thank you! Now, there is my config, but still the error:

The service "gos_web_socket.client_storage" has a dependency on a non-existent service "gos_web_socket.client_storage.driver.predis".

[jjsaunier]

This time the docs is right :D

Checkout https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md#create-your-own-driver

NOTE : Predis driver class is included in GosWebSocketBundle, just register the service like below to use it.

services:
    gos_web_scocket.client_storage.driver.predis:
        class: Gos\Bundle\WebSocketBundle\Client\Driver\PredisDriver
        arguments:
            - @snc_redis.cache

[KrissMcCone]

Yes, I have bad service name linked. Thanks. :)

Fatal error: Call to a member function beginTransaction() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/app/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/Session/Storage/Handler/PdoSessionHandler.php on line 445

[Symfony\Component\Debug\Exception\FatalErrorException]
Error: Call to a member function beginTransaction() on a non-object

Now I have error in symfony engine, lolz. Do you know sth about it?

[jjsaunier]

Yes, your PDO session handler is not correctly setup.

http://symfony.com/doc/master/cookbook/configuration/pdo_session_storage.html

[KrissMcCone]

I've configured this by this tutorial

session.handler.pdo:
        class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
        public:    false
        arguments:
            - "mysql:host=%database_host%;dbname=%database_name%"
            - { db_username: %database_user%, db_password: %database_password% }

And probably everyting works, cos I can login and my session is saved in database.

[jjsaunier]

I will dig into it so

[KrissMcCone]

Thanks so : )

This error occurred in WebSocket console when I connected some user. :)

[jjsaunier]

Symfony PdoSessionHandler bug when dsn (instead of inject pdo instance directly) is used in event loop context.

I have write this part docs : https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md

[KrissMcCone]

Thank you. :)

[Predis\Connection\ConnectionException]
Operation timed out [tcp://0.0.0.0:6379]

Now this after connected some user. Hard to do...

[jjsaunier]

Redis is installed ? (BTW redis driver is optional and proposed to illustrate a concret exemple, you can leave by default to fallback on php driver)

[KrissMcCone]

Yes, some play with configs helps me. :) Thank you

https://github.com/GeniusesOfSymfony/WebSocketBundle/blob/master/Resources/docs/SessionSetup.md

-> Retrieve current user

You have double use Ratchet\ConnectionInterface; in the topic class. :)

[jjsaunier]

Nice catch ! Just fixed thank you !

May the docs on Session setup part is confused and orient people to use another driver to store client ?

[KrissMcCone]

I would add there informaton that you have to install redis server. Rest there is ok, i think. Good job! :) http://redis.io/

[KrissMcCone]

Probably works, but can't use it in topic. hahaha :P

use Gos\Bundle\WebSocketBundle\Client\WebSocketUserTrait;
use Gos\Bundle\WebSocketBundle\Topic\TopicInterface;
use Gos\Bundle\WebSocketBundle\Client\ClientStorageInterface;
use Gos\Bundle\WebSocketBundle\Router\WampRequest;
use Ratchet\ConnectionInterface;
use Ratchet\Wamp\Topic;
use App\ChatBundle\Entity\ChatMessage;
use Doctrine\ORM\Mapping as ORM;

**
     * Constructor
     *
     * @param \Doctrine\ORM\EntityManager $em
     * @param ClientStorageInterface $clientStorage
     */
    public function __construct(\Doctrine\ORM\EntityManager $em, ClientStorageInterface $clientStorage)
    {
        $this->em = $em;
        $this->clientStorage = $clientStorage;
    }

Error:

[Symfony\Component\Debug\Exception\ContextErrorException]
Catchable Fatal Error: Argument 2 passed to App\ChatBundle\Topic\ChatTopic
::__construct() must be an instance of Gos\Bundle\WebSocketBundle\Client\Cl
ientStorageInterface, none given, called in /Applications/XAMPP/xamppfiles/
htdocs/app/app/cache/dev/appDevDebugProjectContainer.php on line 2366 an
d defined

I've tried to use full path in argument but didn't help.

[jjsaunier]

It's normal, you must inject $clientStorage service @gos_web_socket.client_storage into your Topic via the depency injection (like you inject your entity manager)

[KrissMcCone]

I'm really sorry but it still doesn't work.

Now, Fatal Error: Fatal Error: Call to undefined method App\ChatBundle\Topic\ChatTopic::getCurrentUser()

I have:

use Gos\Bundle\WebSocketBundle\Client\WebSocketUserTrait;

So the topic clas doesn't add method from trait, but why lol.

[jjsaunier]

class AcmeTopic implements TopicInterface
{
    use WebSocketUserTrait;

[KrissMcCone]

Ohhh, kill me better!!! :(

Now it works, but session isn't shared. I have to test it.

I also removed DoctrineCacheBundle and SncRedis. Default is the best. :D

[jjsaunier]

I also removed DoctrineCacheBundle and SncRedis. Default is the best. :D

Sure. Use it when you'll have 1000 concurrent users :dancer:

If the session is not shared it's due to your domain.

The domain between your websocket must be the same as your website. Because we use the cookie to auth the user.

Some examples :

Webserver | Websocket 127.0.0.1:80 | 127.0.0.1:8080 -> WORK 127.0.0.1:80 | localhost:8080 -> NOT WORK my-app.dev:80 | my-app.dev:8080 -> WORK my-app.dev:80 | 127.0.0.1:8080 -> NOT WORK

I hope that will help you.

[KrissMcCone]

[2015-05-25 16:52:04] websocket.INFO: Launching Ratchet on localhost:8080
http://localhost/app/web/app_dev.php/chat/open/82

$this->getCurrentUser($connection) return anon-5563377bbd5b7;

Should work 😡😡😡

[jjsaunier]

Your user is authenticated from symfony2 application ?

[KrissMcCone]

Yes. I copied PHPSESSID from firebug, and checked if the record exist in database and everything seems to be ok.

[jjsaunier]

Have you check the firewall name used in websocket bundle config is the same than your security.yml ?

[KrissMcCone]

firewalls:
        main:
            pattern: ^/
            form_login:
                provider: fos_userbundle
                csrf_provider: form.csrf_provider
                use_referer: false
                success_handler: login_success_handler 

            logout:       true
            anonymous:    true

So porbably not xD

[jjsaunier]

Just take your example above, adapt since you update.

# Web Socket Configuration

        router:

        session_handler: @session.handler.pdo
        storage:
            driver: @gos_web_socket.client_storage.driver.predis

[KrissMcCone]

Works perfectly. Thanks a lot. I hope that this topic helps another newbie in symfony like me.

[jjsaunier]

I will continue to improve the docs to be more explicit because the installation of this bundle is heavy and wrap a lot features bring by symfony.

Hi! I yet has this problem:

PHP Fatal error: Call to a member function beginTransaction() on null in /var/www/APSEAB/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/Session/Storage/Handler/PdoSessionHandler.php on line 445 [2015-06-27 12:51:26] php.EMERGENCY: Fatal Error: Call to a member function beginTransaction() on null {"type":1,"file":"/var/www/APSEAB/vendor/symfony/symfony/src/Symfony/Component/HttpFoundation/Session/Storage/Handler/PdoSessionHandler.php","line":445,"level":-1,"stack":[]}

I'm not use redis, my configs:

       class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
        public:    false
        arguments:
            - "mysql:host=%database_host%;dbname=%database_name%"
            - { db_table: sessions, db_username: %database_user%, db_password: %database_password% }

My server is runing in: 127.0.0.1:8000, and websoket in: 127.0.0.1:8080.

Can help me @ProPheT777 @KrissMcCone?

Tanks!

[jjsaunier]

Yes,

services:
session.handler.pdo:
class: Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
public: false
arguments:
- "mysql:host=%database_host%;dbname=%database_name%"
- { db_table: sessions, db_username: %database_user%, db_password: %database_password% }

This definition is wrong.

First of all you need to turn PDO as service like following:

pdo:
    class: PDO
    arguments:
        dsn: mysql:host=%database_host%;dbname=%database_name%
        user: %database_user%
        password: %database_password%
    calls:
        - [ setAttribute, [3, 2] ] # \PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION

Because Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler require it.

and then declare the session handler service:

session.handler.pdo:
    class:     Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler
    arguments: [@pdo, {lock_mode: 0}]

and then it should work. Don't worry about redis, he is not required to run websocket in basic configuration.

[ewertoncode]

Thank's a lot man!!

Works now!!

[hermandinho]

having the same issue here

[Symfony\Component\Debug\Exception\FatalErrorException] Error: Call to a member function beginTransaction() on null

[babukaivan]

Hello, please help me, in onSubscribe method user always anon-**** $user = $this->clientManipulator->getClient($connection);
dump($connection->WebSocket->request->getCookies()); return me PHPSESSID from browser, session shared beetween web and websockets Use predis without doctrine cache

[babukaivan]

I found a problem, my User Session stored in Redis, and if (false !== $serializedToken = $connection->Session->get('security' . $firewall, false)) { always false.

[zeckon]

I have the same issue and traced it to the same point with @babukaivan . serializedToken is empty, Any ideas?

[zeckon]

Ok. I figured it out. In my config, i was using firewall "main" so my config was like

gos_web_socket: client: firewall: main

but actually i have more than 1 firewall and they use same context (which is 'main_auth'). After checking the session bag, I noticed the value is _security_main_auth not _security_main so I changed my config to

gos_web_socket: client: firewall: main_auth

and it works now.

[KooliFiras]
