在本地.env文件配置本地/测试/预发/正式 路径：

在vue.config.js 里面配置：

module.exports = defineConfig({
  transpileDependencies: false,
  lintOnSave: false,
  outputDir: process.env.VUE_APP_DIST,
  publicPath: '/',
  css: {
    loaderOptions: {
      postcss: {
        // postcssOptions: {
        //   plugins: [autoprefixer(), postcss]
        // }
      }
    }
  },
  // 配置路径别名
  chainWebpack: (config) => {
    config.resolve.alias
      .set('@', resolve('./src'))
      .set('components', resolve('./src/components'))
      .set('assets', resolve('./src/assets'))
  },
  // 代理
  devServer: {
    proxy: {
      "/iot": {
        target: process.env.VUE_APP_API_PATH_ONE,
        changeOrigin: true,
        pathRewrite: {
          '^/poi': '',
        }
      },
      "/V1": {
        target: process.env.VUE_APP_API_PATH_TWO,
        changeOrigin: true,
        pathRewrite: {
          '^/V5': '',
        }
      },
      "/api": {
        target: process.env.VUE_APP_API_PATH,
        changeOrigin: true,
        pathRewrite: {
          '^/api': '',
        }
