### 问题描述
在ws.send消息之前只要 onclose 中有耗时操作就会报错

### Swoole版本，PHP版本，以及操作系统版本信息
Version => 4.5.5
centos7
php7.2

### 相关代码
```php
class WebSocket
{
    public $server;
    function __construct($host='0.0.0.0', $port='8082')
    {
        $this->server = new \Swoole\WebSocket\Server($host, $port);
        $this->server->set([
            'log_level' => SWOOLE_LOG_WARNING,
            'heartbeat_check_interval' => 30,
            'heartbeat_idle_time' => 60,
            'reactor_num' => 1,
            'worker_num' => 2,
        ]);

$this->server->on('open', [$this, '_onOpen']);
        $this->server->on('close', [$this, '_onClose']);

$this->server->start();
    }

public function _onOpen($ws, $request){
        $data = $request->get;
        if($data['token'] != 123){
		//不能正常返回code 和 reason !!!!
            $ws->disconnect($request->fd, 1000, '登录已失效,请重新登录。');
        }
    }

public function _onClose($ws, $fd){
        //耗时操作
        sleep(1);
        echo 'quit success'.PHP_EOL;

}
}

new WebSocket();
```

```javascript
<script>

var ws = new WebSocket('ws://127.0.0.1:8082?token=1234');

ws.onopen = function (event) {
        console.log('websocket连接成功...');
        console.log(event);
    };

ws.onclose = function (event) {
        console.log('链接关闭');
        console.log(event);
    };

ws.onerror = function (event) {
        console.log('出错了');
        console.log(event);
    };

</script>
```

### 你期待的结果是什么？实际看到的错误信息又是什么？
期待：$ws->disconnect 可以正常返回错误码 和 reason
实际：![](/storage/article-column/GCP7XlKajrFub4jb4gc4UoApxI66icCLBqg0lRa4.jpeg)
