经常出现这个问题，我跑在本地虚拟机没有看到过，但是在阿里云服务器上就会遇到这个

这段代码是不是关闭的有问题

func (ws *WebSocketOp) Close() {
	ws.conn.Close()
	ws.mutex.Lock()
	defer ws.mutex.Unlock()
	if !ws.isClose {
		ws.isClose = true
		ws.authOk = false
		close(ws.closeChan)
	}
	ws.closeChanCallback <- struct{}{}
}

这样会好点吗

func (ws *WebSocketOp) Close() {
	ws.mutex.Lock()
	ws.conn.Close()
	defer ws.mutex.Unlock()
	if !ws.isClose {
		ws.isClose = true
		ws.authOk = false
		close(ws.closeChan)
	}
	ws.closeChanCallback <- struct{}{}
}
