class Websocket { const HOST = '0.0.0.0'; const PORT = 9502; private $ws = null; public function __construct() { $this->ws = new swoole_websocket_server(self::HOST, self::PORT); $this->ws->set([ 'worker_num' => 2, 'task_worker_num' => 2, // 要想使用task必须要指明 ]); $this->ws->on('open', [$this, 'onOpen']); $this->ws->on('message', [$this, 'onMessage']); $this->ws->on('task', [$this, 'onTask']); $this->ws->on('finish', [$this, 'onFinish']); $this->ws->on('close', [$this, 'onClose']); $this->ws->start(); } public function onOpen($server, $request) { echo "server:handshake success with fd:{$request->fd}\n"; } public function onMessage($server, $frame) { echo "receive from {$frame->fd}:{$frame->data}\n"; // 需要投递的任务数据 $data = [ 'fd' => $frame->fd, 'msg' => 'task', ]; $server->task($data); $server->push($frame->fd, 'this is server'); } // 处理投递的任务方法,非阻塞 public function onTask($server, $task_id, $worker_id, $data) { print_r($data); // 模拟大量数据的操作 sleep(10); return "task_finish"; } // 投递任务处理完毕调用的方法 public function onFinish($server, $task_id, $data) { echo "task_id:{$task_id}\n"; echo "task finish success:{$data}\n"; } public function onClose($server, $fd) { echo "Client:close"; } }
