uni-app electron打包成exe应用

1.安装electron
cnpm install electron -g
2.安装electron-packager
cnpm install electron-packager -g
3.uni-app的manifest.json修改

运行的基础路径修改为：./ 不然打包出来会出现白屏，读取不到，因为打包出来的h5默认加载地址为/static/
去掉启用https协议: 不然会出现网络无法加载，去掉https不影响你请求后端的https协议。

4.打包成H5
5.H5文件夹下新建package.json和main.js
package.json
{ "name" : "exam考试系统", "version" : "0.1.0", "main" : "main.js"}
main.js

const path = require('path')
const url = require('url')
 
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win
 
function createWindow () {
  // Create the browser window.
//设置窗口大小
  //win = new BrowserWindow({width: 400, height: 700})
 设置窗口最大化
  // win = new BrowserWindow({width: 400, height: 700})
 win = new BrowserWindow({show: false})
win.maximize()
win.show()
  // and load the index.html of the app.
  win.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))
 
  // Open the DevTools.
  // win.webContents.openDevTools()
 
  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null
  })
}
 
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow)
 
// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})
 
app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
    createWindow()
  }
})
 
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

6.打包命令：
electron-packager . helloWorld --platform=win32 --arch=x64 --icon=computer.ico --out=./out --asar --app-version=1.0.0 --overwrite --ignore=node_modules --electron-version 8.2.1

参数说明：

HelloWorld ：你将要生成的exe文件的名称
–platform=win32：确定了你要构建哪个平台的应用,可取的值有 darwin, linux, mas, win32
–arch=x64：决定了使用 x86 还是 x64 还是两个架构都用
–icon=自定义.ico：自定义设置应用图标
–out=./out：指定打包文件输出的文件夹位置,当前指定的为项目目录下的out文件夹
–asar：该参数可以不加，如果加上，打包之后应用的源码会以.asar格式存在
–app-version=1.0.0：生成应用的版本号
–overwrite：覆盖原有的build,让新生成的包覆盖原来的包
–ignore=node_modules：如果加上该参数，项目里node_modules模块不会被打包进去
–electron-version 8.2.1：指定当前要构建的electron的电子版本（不带"v"）,需要和当前的版本一致,具体可以在 package.json文件中查看,可以不加该参数，如果不一致，会自动下载。

打包过慢使 使用淘宝映射：
更换阿里镜像源
npm config set ELECTRON_MIRROR http://npm.taobao.org/mirrors/electron/

electron-packager . appName --platform=win32 --electron-version=10.0.0 --arch=x64 --download.mirrorOptions.mirror=https://npm.taobao.org/mirrors/electron/ --asar --app-version=0.0.0 --build-version=0.0.0 --out=outName --overwrite --no-package-manager --ignore="(.git)" --icon=logo.ico
