Error package because of receiving data before handshake

Hi there,

I'm trying to run a basic WebSocket server as described in the README.md.

<?php

use Workerman\Worker;

require __DIR__  . '/../../vendor/autoload.php';

// Create a Websocket server
$ws_worker = new Worker('ws://0.0.0.0:2346');

// Emitted when new connection come
$ws_worker->onConnect = function ($connection) {
    echo "New connection\n";
};

// Emitted when data received
$ws_worker->onMessage = function ($connection, $data) {
    // Send hello $data
    $connection->send('Hello ' . $data);
};

// Emitted when connection closed
$ws_worker->onClose = function ($connection) {
    echo "Connection closed\n";
};

// Run worker
Worker::runAll();

The WebSocket server is started OK.

php cli/workerman/example.php start

Press Ctrl+C to stop. Start success.

However, it'll throw a package error because of receiving data before the handshake.

Error package. package_length=falseConnection closed

By the way, I'm trying to connect to the WebSocket server through the JavaScript console as shown in the image below.

Screenshot 2024-01-30 10:26:45

WebSocket connection to 'ws://127.0.0.1:2346/' failed:

Any help will be very much appreciated!

Thank you,

Thanks for the response,

const ws = new WebSocket('websocket://127.0.0.1:2346');

It seems though as if the websocket protocol can't be used in the JavaScript code.

Uncaught DOMException: Failed to construct 'WebSocket': The URL's scheme must be either 'ws' or 'wss'. 'websocket' is not allowed.
    at <anonymous>:1:12

The URL's scheme must be either ws or wss.

walkor means modify in PHP, not JS.

<?php

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// Create a Websocket server
$ws_worker = new Worker('websocket://0.0.0.0:2346');

// Emitted when new connection come
$ws_worker->onConnect = function ($connection) {
    echo "New connection\n";
};

// Emitted when data received
$ws_worker->onMessage = function ($connection, $data) {
    // Send hello $data
    $connection->send('Hello ' . $data);
};

// Emitted when connection closed
$ws_worker->onClose = function ($connection) {
    echo "Connection closed\n";
};

// Run worker
Worker::runAll();
let socket = new WebSocket("ws://127.0.0.1:2346");

socket.onopen = function(e) {
  alert("[open] Connection established");
  alert("Sending to server");
  socket.send("My name is John");
};

socket.onmessage = function(event) {
  alert(`[message] Data received from server: ${event.data}`);
};

socket.onclose = function(event) {
  if (event.wasClean) {
    alert(`[close] Connection closed cleanly, code=${event.code} reason=${event.reason}`);
  } else {
    // 例如服务器进程被杀死或网络中断
    // 在这种情况下，event.code 通常为 1006
    alert('[close] Connection died');
  }
};

socket.onerror = function(error) {
  alert(`[error] ${error.message}`);
};
