Electron electron-builder.yml 根据环境变量来决定检测更新地址

确保项目里面有.env.production，.env.staging环境变量文件

拷贝一份 electron-builder.yml 命名为 electron-builder.template.yml

检测更新 url 这样写

publish:
  provider: generic
  url: ${VITE_APP_UPDATE_CHECK_URL}

新建一个脚本文件 prebuild.mjs

import fs from 'fs'
import dotenv from 'dotenv'

// 根据环境变量决定加载哪个环境文件
let envPath
switch (process.env.NODE_ENV) {
  case 'staging':
    envPath = '.env.staging'
    break
  default:
    envPath = '.env.production'
    break
}

dotenv.config({ path: envPath })

// console.log('环境变量:', process.env)

const viteUpdateCheckUrl = process.env.VITE_APP_UPDATE_CHECK_URL

console.log('🚢 ~ 当前打印的内容 ~ viteUpdateCheckUrl:', viteUpdateCheckUrl)

if (!viteUpdateCheckUrl) {
  throw new Error('环境变量 VITE_APP_UPDATE_CHECK_URL 未定义')
}

const templatePath = 'electron-builder.template.yml'
console.log('正在读取模板文件:', templatePath)

const template = fs.readFileSync(templatePath, 'utf8')
// console.log('模板内容:', template)

const config = template.replace(/${VITE_APP_UPDATE_CHECK_URL}/g, viteUpdateCheckUrl)

// console.log('配置内容:', config)

fs.writeFileSync('electron-builder.yml', config)
console.log('已写入配置文件到 electron-builder.yml')

安装cross-env库

npm install cross-env -D
