【问题描述】：

所以，我正在尝试 Ratchet 教程 (http://socketo.me/docs/hello-world)，但我遇到了一个问题：每次在 ConnectionInterface 对象上调用 send() 方法时，此客户端都会与服务器断开连接。

下面的例子：

SSH 终端

php server1.php
New connection! (54)
New connection! (83)
Connection 83 sending message "test msg" to 1 other connection
Connection 54 has disconnected

我什至没有在客户端 54 上收到“测试信息”。

我的文件：

server1.php

<?php
use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat1;

    require dirname(__DIR__) . '/vendor/autoload.php';

    $server = IoServer::factory(
        new HttpServer(
            new WsServer(
                new Chat1()
            )
        ),
        8080
    );

    $server->run();

Chat1.php

?php
namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class Chat1 implements MessageComponentInterface {
    protected $clients;

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

    public function onOpen(ConnectionInterface $conn) {
        // Store the new connection to send messages to later
        $this->clients->attach($conn);

        echo "New connection! ({$conn->resourceId})\n";
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        $numRecv = count($this->clients) - 1;
        echo sprintf('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) {
                // The sender is not the receiver, send to each client connected
                $client->send($msg);
            }
        }
    }

    public function onClose(ConnectionInterface $conn) {
        // The connection is closed, remove it, as we can no longer send it messages
        $this->clients->detach($conn);

        echo "Connection {$conn->resourceId} has disconnected\n";
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        echo "An error has occurred: {$e->getMessage()}\n";

        $conn->close();
    }
}

【解决方案1】：

我遇到了类似的错误。

当我检查错误时，我注意到在客户端，当我收到消息时，我在接收方法中编写了会导致连接与客户端断开连接的内容.

此错误与服务器无关
