From 031428add6006d762dccb1431b6483f7044eafd0 Mon Sep 17 00:00:00 2001 From: hant Date: Sun, 7 Dec 2025 13:21:23 +0800 Subject: [PATCH] Implement process-forwarding WebSocket architecture MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New simplified approach: WebSocket server spawns bin/game process and forwards I/O Backend Changes: - New GameProcessServer class (src/Core/GameProcessServer.php) - Implements MessageComponentInterface (Ratchet) - For each WebSocket connection, spawns independent php bin/game process - Uses proc_open() to manage process I/O pipes - Reads process STDOUT/STDERR in non-blocking mode - Writes client input to process STDIN - Automatic process cleanup on disconnect - No game code modifications required - New websocket-process-server.php startup script - Listens on port 9002 - Simple process forwarder without game-specific logic - Suitable for any interactive CLI application Frontend Changes: - New web/process.html - Ultra-simple WebSocket frontend for process I/O - Direct STDIN/STDOUT forwarding - ANSI color support via xterm.js - Minimal dependencies, minimal code - Suitable for any CLI game/application Architecture Benefits: ✓ Zero game code changes needed ✓ Each user gets independent process (isolation) ✓ Real process STDIO, not emulation ✓ ANSI colors work perfectly ✓ Can run ANY CLI application (not just this game) ✓ Simpler than GameSession-based approach ✓ Easier to deploy and manage Usage: 1. Start WebSocket server: php websocket-process-server.php 2. Start HTTP file server (for static files): php -S 0.0.0.0:8080 web/server.php 3. Open browser: http://localhost:8080/process.html Message Protocol: Client → Server: { "type": "input", "input": "command" } - Send stdin to process { "type": "ping" } - Heartbeat Server → Client: { "type": "output", "text": "..." } - Process stdout/stderr { "type": "system", "message": "..." } - Server messages { "type": "error", "message": "..." } - Error messages { "type": "pong" } - Heartbeat response Features: - Non-blocking I/O reading - Stream buffering management - Automatic reconnection support - 30-second heartbeat for keep-alive - Process termination on disconnect - Proper error handling This is the simplest and most elegant approach for running CLI games on web! 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/Core/GameProcessServer.php | 250 +++++++++++++++++++++ web/process.html | 387 +++++++++++++++++++++++++++++++++ web/server.php | 7 + websocket-process-server.php | 58 +++++ 4 files changed, 702 insertions(+) create mode 100644 src/Core/GameProcessServer.php create mode 100644 web/process.html create mode 100755 websocket-process-server.php diff --git a/src/Core/GameProcessServer.php b/src/Core/GameProcessServer.php new file mode 100644 index 0000000..c191692 --- /dev/null +++ b/src/Core/GameProcessServer.php @@ -0,0 +1,250 @@ +resourceId}\n"; + $this->clients[$conn->resourceId] = $conn; + + try { + // 为该连接启动一个游戏进程 + $process = $this->startGameProcess($conn->resourceId); + $this->processes[$conn->resourceId] = $process; + + $this->sendMessage($conn, [ + 'type' => 'system', + 'message' => '游戏进程已启动，正在加载...' + ]); + } catch (\Exception $e) { + $this->sendError($conn, '启动游戏失败: ' . $e->getMessage()); + $conn->close(); + } + } + + /** + * 启动游戏进程 + */ + private function startGameProcess(string $connId): array + { + $gameDir = __DIR__ .
