vue.config.js中的devServer proxy配置（本地开发环境代理后端接口）

module.exports = {
  publicPath: '/publish',
  devServer: {
    open: true,
    hot: true,
    compress: true,
    disableHostCheck: true,
    proxy: {
      '/': {
        target: `http://:/`,
        changeOrigin: true, //跨域
        secure: false, // 使用的是http协议则设置为false，https协议则设置为true
        ws: true,
      },
    },
  },
  css: {
    loaderOptions: {
      less: {
        lessOptions: {
          modifyVars: {
            'primary-color': '#2A77EC',
            'link-color': '#1DA57A',
            'border-radius-base': '2px',
          },
          javascriptEnabled: true,
        },
      },
    },
  },
  chainWebpack: (config) => {
    config.plugin('html').tap((args) => {
      args[0].title = 'xxx';
      return args;
    });
  },
  configureWebpack: (config) => {
    config.devtool = process.env.NODE_ENV === 'development' ? 'source-map' : 'none';
  },
};

生产环境用nginx代理，nginx.conf内容如下：
