该配置文件详细指定了开发服务器如何处理跨域请求。通过设置`historyApiFallback`为true支持HTML5HistoryAPI，`allowedHosts`设为all允许所有主机，`Access-Control-Allow-Origin`设为*允许任何源进行跨域。同时，配置了devServer的代理，将/api路径的请求转发到http://xxx.xxx.xxx.xxx:8082/，并重写了路径，启用changeOrigin以更改源信息，secure参数设为false可能用于忽视HTTPS验证。

配置跨域：

historyApiFallback: true,

allowedHosts: 'all',

headers: {

'Access-Control-Allow-Origin': '*'

}

  devServer: {
    open: true,
    host: 'localhost',
    port: 8081,
    hot: true,
    historyApiFallback: true,
    allowedHosts: 'all',
    headers: {
      'Access-Control-Allow-Origin': '*'
    },
    proxy: {
      '/api': {
        target: 'http://xxx.xxx.xxx.xxx:8082/',
        pathRewrite: {
          '^/api': ''
        },
        changeOrigin: true,
        secure: false
      }
    }
  },
