我正在尝试在我的本地机器上实现 Ratchet Socket Hello 字，一切正常，但在 vps centos 服务器上运行服务器服务时

ssh Command : php chat-server.php

它开始正确侦听端口（我可以在 linux 上看到该端口正在侦听），但是当我打开“clint.html”页面时，该方法onopen永远不会触发，但服务器说

新客户端连接！

2分钟后它说

客户端断开连接

如果我向客户端发送消息，它将需要 2 分钟，然后客户端会收到它，但它会再次断开连接，在我看来，服务器和客户端之间的连接不稳定。每次当我检查 websocket.readyState 它不等于 1
我禁用防火墙和 vps 服务器上的任何安全但仍然有这个问题。我不得不提一下，正常的 php 套接字函数可以正常工作，因为我可以对其进行测试，并且一切正常 ，但是关于棘轮，它似乎挂在onopen方法上。

  • 端口 9091 已打开
  • 防火墙被禁用
  • abrandao.com/2013/06/websockets-html5-php/ 工作白化问题，可以发送和接收来自客户端的消息

  • 但是棘轮在连接上有问题


    聊天服务器.php：

    use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;
require dirname(__DIR__) . '/vendor/autoload.php';

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Chat()
        )
    ),
    9091
);
echo date("Y-m-d H:i:s")." chat-server Started on port 9091 \n";
$server->run();

    Chat.php 类：

    namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Chat implements MessageComponentInterface {
protected $clients;

public function __construct() {
    $this->clients = new \SplObjectStorage;      
}

public function onOpen(ConnectionInterface $conn) {        
    $this->clients->attach($conn);
    echo date("Y-m-d H:i:s")." New connection! ({$conn->resourceId})\n";        
    $conn->send("Hello {$conn->resourceId} from server at : ".date("Y-m-d H:i:s"));
    echo date("Y-m-d H:i:s")." Hello Sent to  ({$conn->resourceId})\n"; 

}

public function onMessage(ConnectionInterface $from, $msg) {
    $numRecv = count($this->clients) - 1;
    echo sprintf(date("Y-m-d H:i:s").'Connection %d sending message "%s" to %d other connection%s' . "\n"
        , $from->resourceId, $msg, $numRecv, $numRecv == 1 ? '' : 's');
    foreach ($this->clients as $client) {
        if ($from !== $client) {                
            $client->send($msg);
        }
    }
}

public function onClose(ConnectionInterface $conn) {        
    $this->clients->detach($conn);
    echo date("Y-m-d H:i:s")." Connection {$conn->resourceId} has disconnected\n";
}

public function onError(ConnectionInterface $conn, \Exception $e) {
    echo date("Y-m-d H:i:s")." An error has occurred: {$e->getMessage()}\n";
    $conn->close();
}
}

    客户端html：

    $(document).ready(function(){  
   connect();  
});

var wsUri = "ws://myserverdomain.comOrIP:9091";   


 function connect() {
  var ws = new WebSocket(wsUri);

  ws.onopen = function() {
    var now = new Date();
    console.log(now + ' Connected to '+wsUri);        
  };

  ws.onmessage = function(e) {
      var now = new Date();
    console.log(now + ' Message Recived From Server :', e.data);
  };

  ws.onclose = function(e) {
      var now = new Date();
    console.log(now +' Socket is closed. Reconnect will be attempted in 1 second.', e.reason);
    setTimeout(function() {
      connect();
    }, 1000)
  };

  ws.onerror = function(err) {
      var now = new Date();
    console.error(now + ' Socket encountered error: ', err.message, 'Closing socket')
    console.error(err)
    ws.close()
  };
}
