# protocol ## 说明: ```php string Connection::$protocol ``` 设置当前连接的协议类 ## 范例 ```php use Workerman\Worker; require_once __DIR__ . '/Workerman/Autoloader.php'; $worker = new Worker('tcp://0.0.0.0:8484'); $worker->onConnect = function($connection) { $connection->protocol = 'Workerman\\Protocols\\Http'; }; $worker->onMessage = function($connection, $data) { var_dump($_GET, $_POST); // send 时会自动调用$connection->protocol::encode()，打包数据后再发送 $connection->send("hello"); }; // 运行worker Worker::runAll(); ```
