# protocol 要求```（workerman >= 3.2.7）``` ## 說明: ```php string Worker::$protocol ``` 設置當前Worker實例的協議類。 注：協議處理類可以直接在初始化Worker在監聽參數時直接指定。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"); }; // 運行worker Worker::runAll(); ``` 以上代碼等價于下面代碼 ```php use Workerman\Worker; require_once __DIR__ . '/Workerman/Autoloader.php'; /** * 首先會查看用戶是否有自定義\Protocols\Http協議類， * 如果沒有使用workerman內置協議類Workerman\Protocols\Http */ $worker = new Worker('http://0.0.0.0:8686'); $worker->onMessage = function($connection, $data) { var_dump($_GET, $_POST); $connection->send("hello"); }; // 運行worker Worker::runAll(); ```
