>本教程探索棘輪,PHP庫促進Websocket通信。 WebSockets啟用瀏覽器和服務器之間的實時,雙向數據交換
密鑰功能:
onOpen
客戶管理:onMessage
>僱用onClose
進行有效的客戶跟踪和目標消息廣播。 onError
SplObjectStorage
組件配置Websocket服務器,通常在端口8080上偵聽。
IoServer
HttpServer
實現:WsServer
在A 目錄中創建a 文件。此類將處理Websocket Events。 composer require cboden/ratchet
>服務器入口點(CMD.PHP):Chat.php
文件以啟動WebSocket服務器。
<?php namespace ChatApp; 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 "New connection established.\n"; } public function onMessage(ConnectionInterface $from, $msg) { foreach ($this->clients as $client) { if ($from !== $client) { $client->send($msg); } } } public function onClose(ConnectionInterface $conn) { $this->clients->detach($conn); echo "Connection closed.\n"; } public function onError(ConnectionInterface $conn, \Exception $e) { echo "Error: " . $e->getMessage() . "\n"; $conn->close(); } }
cmd.php
<?php require 'vendor/autoload.php'; use Ratchet\Server\IoServer; use Ratchet\Http\HttpServer; use Ratchet\WebSocket\WsServer; use ChatApp\Chat; $server = IoServer::factory( new HttpServer( new WsServer( new Chat() ) ), 8080 ); $server->run();
