    $redis->set('test_key', 'value', function ($redis, $result) {
        $redis->get('test_key', function ($redis, $result) {

$cli->post('/dump.php', array("test" => 'abc'), function ($cli) {
    var_dump($cli->body);
    $cli->get('/index.php', function ($cli) {
        var_dump($cli->cookies);
        var_dump($cli->headers);
