I try to run my websocket server but it fails to run for some reason I cant figure out. I used this tutorial: http://socketo.me/docs/hello-world
I have this main folder: enter image description here
composer.js:
{
"autoload": {
"psr-4": {
"dealspace_websocket\\": "websocket_src"
}
},
"require": {
"cboden/ratchet": "^0.4.2"
}
}
Inside websocket_src
folder, there is ONLY 1 file, Chat.php:
<?php
namespace dealspace_websocket;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
require_once __DIR__ . "/../Model/DBConnection.php";
class Chat implements MessageComponentInterface {
protected $clients;
public function __construct() {
$this->clients = new \SplObjectStorage;
}
public function onOpen(ConnectionInterface $conn) {
$this->clients->attach($conn);
}
public function onMessage(ConnectionInterface $from, $msg) {
$JSonMsg = json_decode($msg);
if($JSonMsg['type'] === 'updownvote') {
$connection = new DBConnection();
$allowUpdate = false;
try {
$sql = 'UPDATE `deals`
SET `votes_counter` = :vc
WHERE `id` = :id';
$stmt = $connection->dbh->prepare($sql);
$allowUpdate = $stmt->execute(array(
'vc' => $JSonMsg['data']['votes'],
'id' => $JSonMsg['data']['dealid']
));
if($allowUpdate !== false) {
$dataOBJ->dealid = $JSonMsg['data']['dealid'];
$dataOBJ->votes = $JSonMsg['data']['votes'];
$returnMsg->type = 'updownvote';
$returnMsg->date = $dataOBJ;
foreach($this->clients as $client) {
$client->send(json_encode($returnMsg));
}
}
} catch(PDOException $e) {}
}
}
public function onClose(ConnectionInterface $conn) {
$this->clients->detach($conn);
}
public function onError(ConnectionInterface $conn, \Exception $e) {
$conn->close();
}
}
And the last file, websocket_server.php:
<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use dealspace_websocket\Chat;
require __DIR__ . '/vendor/autoload.php';
$server = IoServer::factory(
new HttpServer(
new WsServer(
new Chat()
)
),
8080
);
$server->run();
?>
Then, when I open the CMD in the main folder, I run: php websocket_server.php
This is the result: enter image description here
Why is that?
You are require
-ing the vendor/autoload.php
file after use
-ing the classes.
Put the require __DIR__ . '/vendor/autoload.php';
at the top of the file and PHP will be able to find the classes.
<?php
require __DIR__ . '/vendor/autoload.php';
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use dealspace_websocket\Chat;
EDIT
There is also one crucial part that i did not notice at first, which is the typo in composer.json
, you need to prefix the path to which the namespace points with a /
to tell composer to look for files under the given directory.
The resulted json
would be:
"psr-4": {
"dealspace_websocket\\": "websocket_src/"
}
After making this change run composer dump-autoload
