1.修改.env后缀文件夹

# just a flag
ENV = 'production'

# base api
VUE_APP_BASE_API = 'http://10.10.1.1:8080'

# 生产环境打包文件
outputDir = prod

文件名修改

2.修改package.json配置

  "scripts": {
    "dev": "vue-cli-service serve",
    "build:prod": "vue-cli-service build --mode prod",
    "build:test": "vue-cli-service build --mode test",
    "preview": "node build/index.js --preview",
    "svgo": "svgo -f src/icons/svg --config=src/icons/svgo.yml",
    "test:unit": "jest --clearCache && vue-cli-service test:unit",
    "test:ci": "npm run lint && npm run test:unit"
  }

3.修改vue.config.js配置

'use strict'
const path = require('path')
const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const name = defaultSettings.title || 'vue Admin Template' // page title

const port = process.env.port || process.env.npm_config_port || 9528 // dev port

module.exports = {
  publicPath: './',                                     // 基本路径
  outputDir: process.env.outputDir,                     // 配置文件中的值，用于修改打包文件名称
  lintOnSave: false,                                    // eslint-loader 是否在保存的时候检查
  assetsDir: 'static',                                  // 输出的资源，所在的文件夹
  productionSourceMap: false,                           // 如果你不需要生产环境的 source map，可以将其设置为 false 以加速生产环境构建
  filenameHashing: false,                               // build之后生成的静态资源默认情况下加了hash值以控制静态资源的缓存，默认是true
  devServer: {
    https: false,                                       // https: { type: Boolean }
    port: port,                                         // 端口号
    open: true,                                         // 配置自动启动浏览器 true/false
    overlay: {
      warnings: false,
      errors: true
    },
    proxy: {
      '/api': {
        target: 'http://10.10.1.45:8080',               // 要访问的跨域的域名
        changeOrigin: true,                             // 开启代理：在本地会创建一个虚拟服务端，然后发送请求的数据，并同时接收请求的数据，这样客户端和服务端进行数据的交互就不会有跨域问题
        secure: false,                                  // 使用的是http协议则设置为false，https协议则设置为true
        ws: true,                                       // 是否启用websockets
        pathRewrite: {
          '^/api': ''
        }
      }
    }
  },
