Vue-CLI 3 scp2自动部署项目至服务器的方法

npm install scp2 --save-dev

// .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.',// 域名可以忽略
  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];

// yirenck/index.js里面
