設置當前Worker實例所使用的傳輸層協議，目前只支持3種(tcp、udp、ssl)。不設置默認為tcp。 `注意：ssl需要Workerman版本>=3.3.7` ## [范例 1](https://www.workerman.net/doc/workerman/worker/transport.html#%E8%8C%83%E4%BE%8B%201) ~~~php use Workerman\Worker; use Workerman\Connection\TcpConnection; require_once __DIR__ . '/vendor/autoload.php'; $worker = new Worker('text://0.0.0.0:8484'); // 使用udp協議 $worker->transport = 'udp'; $worker->onMessage = function(TcpConnection $connection, $data) { $connection->send('Hello'); }; // 運行worker Worker::runAll(); ~~~ ## [范例 2](https://www.workerman.net/doc/workerman/worker/transport.html#%E8%8C%83%E4%BE%8B%202) ~~~php <?php use Workerman\Worker; use Workerman\Connection\TcpConnection; require_once __DIR__ . '/vendor/autoload.php'; // 證書最好是申請的證書 $context = array( 'ssl' => array( 'local_cert' => '/etc/nginx/conf.d/ssl/server.pem', // 也可以是crt文件 'local_pk' => '/etc/nginx/conf.d/ssl/server.key', ) ); // 這里設置的是websocket協議 $worker = new Worker('websocket://0.0.0.0:4431', $context); // 設置transport開啟ssl，websocket+ssl即wss $worker->transport = 'ssl'; $worker->onMessage = function(TcpConnection $con, $msg) { $con->send('ok'); }; Worker::runAll(); ~~~
