你这个东西，直接用easyswoole框架的组件就可以实现。

$client = new \EasySwoole\HttpClient\HttpClient('ws://127.0.0.1:9502?user_id=xxxxxx');
$upgradeResult = $client->upgrade();
$frame = new \Swoole\WebSocket\Frame();
//设置发送的消息帧
$frame->data = json_encode(['action' => 'hello','content'=>['a'=>1]]);
$pushResult = $client->push($frame);
$recvFrame = $client->recv();
//将返回bool或一个消息帧，可自行判断
var_dump($recvFrame);
