# protocol 要求```（workerman >= 3.2.7）``` ## 说明: ```php string Worker::$protocol ``` 设置当前Worker实例的协议类。 注：协议处理类可以直接在初始化Worker在监听参数时直接指定。例如 ```php $worker = new Worker('http://0.0.0.0:8686'); ``` ## 范例 ```php use Workerman\Worker; require_once __DIR__ . '/Workerman/Autoloader.php'; $worker = new Worker('tcp://0.0.0.0:8686'); $worker->protocol = 'Workerman\\Protocols\\Http'; $worker->onMessage = function($connection, $data) { var_dump($_GET, $_POST); $connection->send("hello"); }; // 运行worker Worker::runAll(); ``` 以上代码等价于下面代码 ```php use Workerman\Worker; require_once __DIR__ . '/Workerman/Autoloader.php'; /** * 首先会查看用户是否有自定义\Protocols\Http协议类， * 如果没有使用workerman内置协议类Workerman\Protocols\Http */ $worker = new Worker('http://0.0.0.0:8686'); $worker->onMessage = function($connection, $data) { var_dump($_GET, $_POST); $connection->send("hello"); }; // 运行worker Worker::runAll(); ```
