小程序Jenkins部署实践

背景和说明：

代码是同一份，根据不同业务场景，打包出不同渠道的小程序，小程序之间的区别是功能的删减、底部菜单首页、业务接口传参带上不同的渠道号
该项目使用的是uniapp
本文章只涉及打包微信小程序

遇到的问题：

提测之后和每次修改bug，都需要打包给测试同事新包，而且不同渠道就要打不同的包，平均打一次包就要花费2min~3min，很浪费时间；打包过程占用本地机器的资源，导致电脑卡顿；打完包之后还要手动发包给测试，每个包还要重命名标识渠道。
每次提审小程序，都需要一次性打包多个渠道小程序，然后手动一个个小程序去上传，然后填写一模一样的提审信息，还要手动添加一些本渠道的标识信息，很容易出错。

问题分析：

问题1

其实可以通过写一个shell脚本，或者node脚本，实现打包、把目标文件夹变成zip包、重命名。
缺点是：①占用本地机器的资源，导致工作效率低下；②用脚本打包，需要填写参数，不方便且不直观。
更好的方案：使用Jenkins，且可以让测试自行打包和下载包。

问题2

其实可以用微信小程序cli来上传包，然后再用脚本来解决批量上传的问题。
缺点，除了问题1提到的缺点，还有：①cli的路径，在每个开发者的电脑上是不一致的，而且还要考虑是windows还是mac机器；②使用cli打包，第一次需要扫码，且还要考虑过期的问题，还要考虑个别开发者没有权限
更好的方案：使用miniprogram-ci + Jenkins，免登录且自动化

规划&效果展示

问题1，只出现在测试环境下；问题2，只出现在生产环境下。所以要部署两套Jenkins，而且对应的Jenkinsfile也区分开

针对问题搭建的Jenkins：test

针对问题搭建的Jenkins：prod

使用miniprogram-ci上传的脚本

// 使用miniprogram-ci上传
const program = require('commander');
const ci = require('miniprogram-ci');
program
    .version('1.0.0')
    .option('-i, --appid [APPID]', '模板小程序appid')
    .option('-p, --projectpath [PROJECTPATH]', '项目路径')
    .option('-v, --ver [VER]', '小程序版本')
    .option('-d, --desc [DESC]', '版本描述')
    .parse(process.argv);
;(async () => {
  const project = new ci.Project({
    appid: `${program.appid}`,
    type: 'miniProgram',
    projectPath: program.projectpath,
    privateKeyPath: `build/upload/privatekeys/private.${program.appid}.key`,
    ignores: ['node_modules/**/*'],
  })
  const uploadResult = await ci.upload({
    project,
    version: program.ver,
    desc: program.desc,
    setting: {
      es6: true,
      es7: true,
      autoPrefixWXSS: true,
      minify: true
    }
  })
  console.log(uploadResult)
})()

补充说明

Jenkinsfile，是用groovy语法，如果想添加一些函数之类的，可以查一下对应的语法，我用到的isInChannels方法就是用的groovy语法
Jenkins默认不支持多选，需要安装Extend Choice Parameter插件
