reConnect 方法

重连。一般在onClose回调中调用，实现断线重连。

$delay

如果不传或者值为0则代表立即重连。

无返回值

use \Workerman\Worker;
use \Workerman\Connection\AsyncTcpConnection;
require_once __DIR__ . '/Workerman/Autoloader.php';
$worker = new Worker();
$worker->onWorkerStart = function($worker)
{
    $con = new AsyncTcpConnection('ws://echo.websocket.org:80');
    $con->onConnect = function($con) {
        $con->send('hello');
    };
    $con->onMessage = function($con, $msg) {
    $con->onClose = function($con) {
        // 如果连接断开，则在1秒后重连
        $con->reConnect(1);
    };
    $con->connect();
};
Worker::runAll();
