如何在一个Python脚本中使用WebSocket和webserver

我想创建一个电动汽车充电器（电动车）服务器的原型，这样电动汽车充电桩就可以通过网站进行管理。因此，我创建了一个非常简单的Python脚本，充电桩可以通过WebSocket连接到服务器。同时，Web服务器应连接到同一服务器。因此，脚本应该能够通过WebSocket和http接受传入连接

我创建了下面的脚本，它可以正常工作。如果我使用netstat，我可以看到端口8000和9000正在侦听并接受连接。但是，问题是没有触发_connect上的功能。哪里出了什么问题，或者我错过了什么

为了记录在案，我是Python的新手。非常感谢您的帮助
