webpack 配置端口 反向代理

Question

我想通过配置webpack.config.js 来修改本地端口号并配置反向代理
但是端口号和代理都没起作用
其他设置倒是正常，可以使用
请问是怎么回事

devServer: {
        contentBase: "./public",//本地服务器所加载的页面所在的目录
        colors: true,//终端中输出结果为彩色
        historyApiFallback: true,//不跳转
        inline: true,//实时刷新
        port: '8080',

           //配置服务器
        proxy:{
           '/v4/api/*': {
                  target: 'http://m.maizuo.com',
                  host: 'm.maizuo.com',
                  changeOrigin:true
              }
        }
    },

pack,json配置

"scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }

你要使用 webpack-dev-server 这个包啊，
然后配置package.json

 "start": "webpack-dev-server --config webpack.config.js",
