php-ocpp-1.6J

Ready php script for WS/WSS server operation with OCPP 1.6J protocol for charging electric vehicles, tested on php version 7.1 - 8.0

1. Install php library WebSocket Ratchet (http://socketo.me/docs/install) on your server, use my composer.json
2. For OCPP 1.6J to work correctly, you need to change the standard headers in the /vendor/ratchet/rfc6455/src/Handshake/ServerNegotiator.php file. The contents of the “handshake” function are changed to

public function handshake(RequestInterface $request)
{
   $headers = [];
   $response = new Response(101, array_merge($headers, [
       'Upgrade'              => 'websocket'
       , 'Connection'           => 'Upgrade'
       , 'Sec-WebSocket-Version' => '13'
       , 'Sec-WebSocket-Protocol' => 'ocpp1.6'
       , 'Sec-WebSocket-Accept' => $this->sign((string)$request->getHeader('Sec-WebSocket-Key')[0])
   ]));
   return $response;
}

3. Use my files that I uploaded to the repository

/start.php is responsible for starting the WS/WSS server
/src/Desc.php main methods for WS/WSS server operation
/src/Init.php Basic methods for running OCPP 1.6J
/src/config/define.php connection to Mysql database
/src/MySQL.php file for database operation

4. To start and further keep the WS/WSS server in operation, be sure to use Supervisor (http://supervisord.org) or, as an alternative, I recommend using the php script https://github.com/Firehed/ProcessManager

My code was written in 2020 and is still functioning, I own my own electric car charging project.
