$con = new AsyncTcpConnection('ws://****.com/随机字符串', $context_option);
$con->transport = 'ssl';

$con->onConnect = function($con) {

};

$con->onMessage = function($con, $data) {
    echo $data;
};

$con->onClose = function($con){
    echo "connection closed\n";
    Timer::add(5, array($con, 'connect'), null, false);
