关于报错WebSocket connection to 'ws:

解决办法

修改webpack配置如下
devServer.proxy的ws为false

    devServer: {
        ...
        proxy: {
            "/": {
                target: 'http:xxx',
                changeOrigin: true,
                ws: false,
                secure: false,
            }
        }
    },
