一、安装

安装electron,electron-builder,vue-cli-plugin-electron-builder,electron-devtools

npm i --save-dev electron electron-builder vue-cli-plugin-electron-builder electron-devtools

二、创建background.js

vue-cli项目src下创建background.js文件

// Modules to control application life and create native browser window
const {app, BrowserWindow, screen, ipcMain, dialog, Tray, protocol} = require('electron')
import {createProtocol} from 'vue-cli-plugin-electron-builder/lib'

const fs = require('fs');
const path = require('path')
const electron = require('electron');
/*获取electron窗体的菜单栏*/
const Menu = electron.Menu;
/*隐藏electron创听的菜单栏*/
Menu.setApplicationMenu(null);
let mainWindow;
let appTray = null;
let preFix = './';
if (process.env.NODE_ENV === 'development') {
  preFix = "./bundled/";
}

// Scheme must be registered before the app is ready
protocol.registerSchemesAsPrivileged([{
  scheme: 'app',
  privileges: {
    secure: true,
    standard: true,
    supportFetchAPI: true
  }
}])

// 隐藏主窗口,并创建托盘,绑定关闭事件
function setTray(mainWindow) {
  // 用一个 Tray 来表示一个图标,这个图标处于正在运行的系统的通知区
  // 通常被添加到一个 context menu 上.
  // 系统托盘右键菜单
  const trayMenuTemplate = [
    {
      type: 'checkbox',
      label: '开机启动',
      checked: app.getLoginItemSettings().openAtLogin,
      click: function () {
        if (!app.isPackaged) {
          app.setLoginItemSettings({
            openAtLogin: !app.getLoginItemSettings().openAtLogin,
            path: process.execPath
          })
        } else {
          app.setLoginItemSettings({
            openAtLogin: !app.getLoginItemSettings().openAtLogin
          })
        }
      }
    },
    {
      // 系统托盘图标目录
      label: '退出',
      click: () => {
        app.quit();
      }
    }
  ];
  // 设置系统托盘图标
  let filePath = preFix + 'favicon.ico';
  const iconPath = path.join(__dirname, filePath);
  appTray = new Tray(iconPath);
  const win = BrowserWindow.getFocusedWindow()
  // 图标的上下文菜单
  const contextMenu = Menu.buildFromTemplate(trayMenuTemplate);

  // 展示主窗口,隐藏主窗口 mainWindow.hide()
  mainWindow.show();

  // 设置托盘悬浮提示
  appTray.setToolTip('Saturn');

  // 设置托盘菜单
  appTray.setContextMenu(contextMenu);

  // 单击托盘小图标显示应用
  // appTray.on('click', () => {
  //     //显示主程序
  //     mainWindow.show();
  //     //关闭托盘显示
  //     // appTray.destroy();
  // });
  appTray.on('double-click', () => {
    win.isVisible() ? win.hide() : win.show()
  })
  return appTray;
}

function createWindow(scheme, handler) {
  // Create the browser window.
  const displayWorkAreaSize = screen.getAllDisplays()[0].workArea
  const width = displayWorkAreaSize.width;
  const height = displayWorkAreaSize.height;
  mainWindow = new BrowserWindow({
    width: width / 2 + 100,
    height: height - 10,
    x: width - (width / 2 + 100) - 5,
    y: 5,
    // width: 1920,
    // height: 1350,
    transparent: true,
    resizable: false,
    movable: true,
    frame: false,
    alwaysOnTop: false,
    backgroundColor: '#00000000',
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      //关闭web权限检查,允许跨域
      webSecurity: false,
      nodeIntegration: true,
      contextIsolation: false,
      enableRemoteModule: true,
    }
  })

  // and load the index.html of the app.
  // mainWindow.loadFile('index_bak.html')
  let filePath = preFix + 'index.html';
  mainWindow.loadFile(path.join(__dirname, filePath))

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()
  setTray(mainWindow);

  mainWindow.setSkipTaskbar(true) // 使窗口不显示在任务栏中

  //程序崩溃后
  mainWindow.webContents.on('crashed', () => {
    const options = {
      type: 'error',
      title: '进程崩溃了',
      message: '这个进程已经崩溃.',
      buttons: ['重载', '退出'],
    };
    recordCrash().then(() => {
      dialog.showMessageBox(options, (index) => {
        if (index === 0) reloadWindow(mainWindow);
        else app.quit();
      });
    }).catch((e) => {
      console.log('err', e);
    });
  })

  function recordCrash() {
    return new Promise(resolve => {
      // 崩溃日志请求成功....
      resolve();
    })
  }

  function reloadWindow(mainWin) {
    if (mainWin.isDestroyed()) {
      app.relaunch();
      app.exit(0);
    } else {
      BrowserWindow.getAllWindows().forEach((w) => {
        if (w.id !== mainWin.id) w.destroy();
      });
      mainWin.reload();
    }
  }

}

// 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.whenReady().then(() => {
  createProtocol('app')
  createWindow()

  app.on('activate', function () {
    // 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 (BrowserWindow.getAllWindows().length === 0) createWindow()
  })
})

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', function () {
  if (process.platform !== 'darwin') app.quit()
})

/**
 * 开机自动启动
 * */
const exeName = path.basename(process.execPath)
app.setLoginItemSettings({
  openAtLogin: true,
  openAsHidden: false,
  path: process.execPath,
  args: [
    '--processStart', `"${exeName}"`,
  ]
})

/**
 * 窗口控制
 * */
// 1. 窗口 最小化
ipcMain.on('window-min', function () { // 收到渲染进程的窗口最小化操作的通知,并调用窗口最小化函数,执行该操作
  mainWindow.minimize();
})

// 2. 窗口 最大化、恢复
ipcMain.on('window-max', function () {
  if (mainWindow.isMaximized()) { // 为true表示窗口已最大化
    mainWindow.restore();// 将窗口恢复为之前的状态.
  } else {
    mainWindow.maximize();
  }
})

// 3. 关闭窗口
ipcMain.on('window-close', function () {
  // mainWindow.close();
  mainWindow.setSkipTaskbar(true) // 使窗口不显示在任务栏中
  mainWindow.hide() // 隐藏窗口
})

/**
 * 读写文件
 * */
ipcMain.on('read-message', function (event, arg) {
  // arg是从渲染进程返回来的数据
  // 这里是传给渲染进程的数据
  fs.readFile(path.join(__dirname, "./loginInfo.json"), "utf8", (err, data) => {
    if (err) {
      event.sender.send('read-reply', "读取失败");
    } else {
      event.sender.send('read-reply', data);
    }
  })
});


ipcMain.on('write-message', function (event, arg) {
  // arg是从渲染进程返回来的数据
  fs.writeFile(path.join(__dirname, "./loginInfo.json"), JSON.stringify(arg), "utf8", (err) => {
      if (err) {
        event.sender.send('write-reply', "写入失败");
      } else {
        event.sender.send('write-reply', "写入成功");
      }
    }
  )
  // 通过event.sender.send给渲染进程传递数据
});

三、创建preload.js文件

在vue-cli 项目src下 创建 preload.js

import { contextBridge, ipcRenderer } from 'electron'
window.ipcRenderer = ipcRenderer

contextBridge.exposeInMainWorld('ipcRenderer', {
  // 异步向主进程 发送消息
  send: (channel, data) => {
    let validChannels = ['toMain', 'downLoad', 'judgeUse', 'hideMenu', 'showMenu', 'window-close', 'asyncGetLocalServer']
    if (validChannels.includes(channel)) {
      ipcRenderer.send(channel, data)
    }
  },
  // 同步向主进程 发送消息,
  sendSync: (channel, data) => {
    let validChannels = ['syncGetLocalServer']
    if (validChannels.includes(channel)) {
      return ipcRenderer.sendSync(channel, data)
    }
  },
  // 异步接收主进程返回的数据
  receive: async (channel) => {
    let validChannels = ['authorizeBack', 'asyncBackLocalServer']
    if (validChannels.includes(channel)) {
      return new Promise((resolve) => {
        ipcRenderer.on(channel, (event, ...args) => {
          resolve(...args)
        })
      });

    }
  }
})

四、修改package.json文件

{
  "name": "ruoyi",
  "version": "3.1.0",
  "description": "若依管理系统",
  "author": "若依",
  "license": "MIT",

  },
  "browserslist": [
    "> 1%",

  ],
  "__npminstall_done": false,

}

五、修改vue.config.js文件

'use strict'
const path = require('path')

const defaultSettings = require('./src/settings.js')

function resolve(dir) {
  return path.join(__dirname, dir)
}

const name = defaultSettings.title //process.env.VUE_APP_TITLE || '若依管理系统' // 网页标题
const BASE_URL = process.env.NODE_EVN === 'production' ? './' : './'
const port = process.env.port || process.env.npm_config_port || 80 // 端口
// vue.config.js 配置说明
//官方vue.config.js 参考文档 https://cli.vuejs.org/zh/config/#css-loaderoptions
// 这里只列一部分,具体配置参考文档
module.exports = {
  // 部署生产环境和开发环境下的URL。
  // 默认情况下,Vue CLI 会假设你的应用是被部署在一个域名的根路径上
  // 例如 https://www.ruoyi.vip/。如果应用被部署在一个子路径上,你就需要用这个选项指定这个子路径。例如,如果你的应用被部署在 https://www.ruoyi.vip/admin/,则设置 baseUrl 为 /admin/。
  publicPath: BASE_URL,
  // publicPath: process.env.NODE_ENV === "production" ? "/" : "/",
  // 在npm run build 或 yarn build 时 ,生成文件的目录名称(要和baseUrl的生产环境路径一致)(默认dist)
  outputDir: 'dist',
  // 用于放置生成的静态资源 (js、css、img、fonts) 的;(项目打包之后,静态资源会放在这个文件夹下)
  assetsDir: 'static',
  // 是否开启eslint保存检测,有效值:ture | false | 'error'
  lintOnSave: process.env.NODE_ENV === 'development',
  // 如果你不需要生产环境的 source map,可以将其设置为 false 以加速生产环境构建。
  productionSourceMap: false,
  // webpack-dev-server 相关配置
  devServer: {
    host: '0.0.0.0',
    port: port,
    open: true,
    proxy: {

    },
    disableHostCheck: true
  },
  configureWebpack: {

              to: './', //到根目录下
            }
        }
      )
  }
}

六、启动

1 本地启动

npm run electron:serve

2 打包

npm run electron:build

打包成功后在build文件夹会生成exe安装文件
在这里插入图片描述

补充:

  1. 启动发现资源请求不到,先执行npm run electron:build(会生成dist_electron文件夹及相关文件),再执行npm run electron:serve,然后将dist_electron/bundled/static 复制一份static放到dist_electron文件夹下
    (不要问我为什么,我也不知道……时间紧,任务重,有时间再去研究-_-||)
  2. 接口协议是File的参考上一篇解决 vue项目通过Electron生成桌面应用
