Chrome 不允许不安全的 websocket (ws) 连接到本地主机(仅限 wss，因此您应该为本地 web/websocket 服务器设置 TLS 证书).但是，Firefox 应该也能正常工作.

Chrome doesn't allow unsecure websocket (ws) connections to localhost (only wss, so you should setup a TLS certificate for your local web/websocket server). However the same should work fine with Firefox.
