主界面显示Data Websocket API is connected. 但是报以上错误, 无法正常连接.

我们已经重新开发实现了vnpy_evo.websocket和vnpy_evo.rest两个模块。

使用线程池 + 同步客户端的方式，替代了官方基于asyncio的实现。

经过我们测试基本解决了各种奇怪的异步问题，同时也方便各种脚本使用。

这里也分享我们团队的经验：

1. asyncio异步机制，对于网络通讯的并发量有优势，对于速度延时没有优势（甚至是劣势）
2. 因此asyncio的主要使用场景，是网络服务端的开发（比如FastAPI开发的各种Web服务）
3. 而VN的交易接口gateway，是典型的网络客户端应用，使用asyncio无异于用大卡车去跑赛道
4. 因此更合适的方案依然是基于线程池的同步机制（requests和websocket-client）
