Vue CLI 3.x 自动部署项目至服务器的方法

// .env.dev文件中
VUE_APP_SERVER_ID=0

// .env.prod文件中
VUE_APP_SERVER_ID=1

/
 读取env环境变量
 /
const fs = require('fs');
const path = require('path');
// env 文件 判断打包环境指定对应的服务器id
const envfile = process.env.NODE_ENV === 'prod' ? '../.env.prod' : '../.env.dev';
// env环境变量的路径
const envPath = path.resolve(__dirname, envfile);
// env对象
const envObj = parse(fs.readFileSync(envPath, 'utf8'));
const SERVER_ID = parseInt(envObj['VUE_APP_SERVER_ID']);
function parse(src) {
 // 解析KEY=VAL的文件
 const res = {};
 src.split('\n').forEach(line => {
 // matching "KEY' and 'VAL' in 'KEY=VAL'
 // eslint-disable-next-line no-useless-escape
 const keyValueArr = line.match(/^\s([\w\.\-]+)\s=\s(.)?\s$/);
 // matched?
 if (keyValueArr != null) {
  const key = keyValueArr[1];
  let value = keyValueArr[2] || '';

  // expand newlines in quoted values
  const len = value ? value.length : 0;
  if (len > 0 && value.charAt(0) === '"' && value.charAt(len - 1) === '"') {
  value = value.replace(/\\n/gm, '\n');
  }

  // remove any surrounding quotes and extra spaces
  value = value.replace(/(^['"]|['"]$)/g, '').trim();

  res[key] = value;
 }
 });
 return res;
}
/
 定义多个服务器账号 及 根据 SERVER_ID 导出当前环境服务器账号
 /
const SERVER_LIST = [
 {
 id: 0,
 name: 'A-生产环境',
 domain: '.prod.',// 域名
 host: '46.106.38.24',// ip
 port: 22,// 端口
 username: 'root', // 登录服务器的账号
 password: 'Rock@sz18!',// 登录服务器的账号
 path: '/mdm/nginx/dist'// 发布至静态服务器的项目路径
 },
 {
 id: 1,
 name: 'B-测试环境',
 domain: 'test.xxx.',
 host: 'XX.XX.XX.XX',
 port: 22,
 username: 'root',
 password: 'xxxxxxx',
 path: '/usr/local//xxx_program_test/'
 }
];

module.exports = SERVER_LIST[SERVER_ID];

const scpClient = require('scp2');
const ora = require('ora');
const chalk = require('chalk');
const server = require('./products');
const spinner = ora('正在发布到' + (process.env.NODE_ENV === 'prod' ? '生产' : '测试') + '服务器...');
spinner.start();
scpClient.scp(
 'dist/',
 {
 host: server.host,
 port: server.port,
 username: server.username,
 password: server.password,
 path: server.path
 },
 function (err) {
 spinner.s();
 if (err) {
  console.log(chalk.red('发布失败.\n'));
  throw err;
 } else {
  console.log(chalk.green('Suess! 成功发布到' + (process.env.NODE_ENV === 'prod' ? '生产' : '测试') + '服务器! \n'));
 }
 }
