vue3使用Electron打包成exe的方法与打包报错解决_Javascript

一、安装

1.安装electron

npm install electron --save-dev
npm install electron-builder --save-dev

2.在vue项目根目录新建文件index.js

// main.js

// modules to control application life and create native browser window
const { app, browserwindow,menu } = require('electron')

const createwindow = () => {
  // create the browser window.
  const mainwindow = new browserwindow({
    width: 800,
    height: 600,
    webpreferences: {
      nodeintegration: true, // 启用 node.js 集成
      contextisolation: false, // 禁用上下文隔离（node.js 集成的一个选项）
      websecurity: false, // 禁用同源策略
      contextisolation: false,
      session: {
        cookies: true // 这行确保启用了cookie
      }

    },
    icon: 'build/.icon-ico/icon.ico'//这里是自动生成的图标，默认情况下不需要改

  })

  // and load the index.html of the app.
  mainwindow.loadfile('./dist/index.html')//如果要本地化，这样写，如果写远程的，那这里就是请求的域名
  //隐藏顶部菜单
  // mainwindow.setmenu(null);
  // open the devtools.
  // open the devtools.
  //mainwindow.webcontents.opendevtools()
  mainwindow.maximize();//默认最大化
}
//设置中文菜单，默认是英文的
const createmenu = () => {
  const template = [
    {
      label: '文件',
      submenu: [
        {
          label: '退出',
          accelerator: 'cmdorctrl+q',
          click: () => {
            app.quit();
          }
        }
      ]
    },
    {
      label: '查看',
      submenu: [
        { label: '重新加载', accelerator: 'f5', role: 'reload' },
        { label: '全屏', accelerator: 'f11', role: 'togglefullscreen' },
        { label: '开发者工具', role: 'toggledevtools' }
      ]
    }
  ];

  const menu = menu.buildfromtemplate(template);
  menu.setapplicationmenu(menu);
}

// 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(() => {
  createwindow()
  createmenu()//菜单设置
  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 (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', () => {
  if (process.platform !== 'darwin') app.quit()
})

// 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.

3.package.json文件编辑

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "electron:build": "vue-cli-service build && electron-builder",
    "electron:serve": "electron ."
  },
  "build": {
    "productname": "这里是你的项目名",
    "appid": "com.example.这里是appid",
    "win": {
      "icon": "favicon.ico",
      "target": ["nsis", "appx"]
    },
    "directories": {
      "output": "build"
    },
    "files": [
      "dist/**/*",
      "index.js"//这里是刚才建的index.js
    ]
  },

4.测试

npm run electron:serve

5.打包

npm run electron:build

二、报错解决

解决：打开cmd 执行 npm config edit

npm config edit

打开配置文件粘贴以下内容

registry=https://registry.npm.taobao.org/
sass_binary_site=https://npm.taobao.org/mirrors/node-sass/
phantomjs_cdnurl=http://npm.taobao.org/mirrors/phantomjs
electron_mirror=https://npm.taobao.org/mirrors/electron/
electron_mirror=http://npm.taobao.org/mirrors/electron/

三、使用

真正用的时候会出现各种，比例启动exe的图标，cookie。

还有就是，平时我的打包项目不需要指定域名，如果这里用本地化就需要指定域名。

默认配置是不开启cookie的，还有就是用cookie不太好，每次启动exe都需要登录太麻烦了，推荐使用localstorage永久保存。

我的cookie示例，打包exe时使用localstorage，其他情况下使用cookie：

 setcookie(cname, cvalue)
 {
    if(process.env.node_env === "host"){
        localstorage.setitem(cname, cvalue);

    }else{
        document.cookie = cname + "=" + cvalue
    }
    //  var d = new date();
    //  d.settime(d.gettime() + (exdays * 24 * 60 * 60 * 1000));
    //  var expires = "expires=" + d.toutcstring();
     //document.cookie = cname + "=" + cvalue

 },
 getcookie(cname) {
    if(process.env.node_env === "host"){
        return localstorage.getitem(cname);
    }else{
        var name = cname + "=";
        var ca = document.cookie.split(';');
        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charat(0) == ' ') c = c.substring(1);
            if (c.indexof(name) != -1) {
                return c.substring(name.length, c.length);
            }
        }
        return "";

    }
 },
 clearcookie(cname) {
    if(process.env.node_env === "host"){
        localstorage.removeitem(cname);
    }else{
        var d = new date();
        d.settime(-1);
        var expires = "expires=" + d.toutcstring();
        document.cookie = cname + "=''; " + expires;
    }
},

其他代码一并粘出来分享一下。

main.js

const env = process.env.node_env || 'development';

if(env === "host"){//如果是打包exe需要指定接口域名
    axios.defaults.baseurl = process.env.vue_app_interface
    axios.defaults.withcredentials = true;//跨域请求的全局凭证

}

package.json

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "electron:build": "vue-cli-service build --mode host && electron-builder",//使用.env.host配置打包exe
    "electron:serve": "electron ."
  },
  "build": {
    "productname": "newsaas",
    "appid": "com.example.newsaas",
    "win": {
      "icon": "./icon256.png",//这里是启动图标必须是256*256的png图
      "target": [
        "nsis",
        "appx"
      ]
    },
    "mac": {
      "target": "dmg"
    },
    "nsis": {
      "oneclick": true,
      "allowtochangeinstallationdirectory": true,
      "permachine": true,
      "allowelevation": true,
      "createdesktopshortcut": true,
      "createstartmenushortcut": true,
      "shortcutname": "index"

    },
    "directories": {
      "output": "build"
    },
    "files": [
      "dist/**/*",
      "index.js",
      "public/favicon.ico"
    ]
  },

.dev

node_env=""
vue_app_interface="这里是我的接口域名，只能本地开发时，做代理用，打包不影响"

.dev.host

node_env="host"
vue_app_interface="http://这里是我的接口域名"

vue.config.js

const { defineconfig } = require('@vue/cli-service')

module.exports = defineconfig({
    devserver:{
      port:8080,
      allowedhosts: "all",
      websocketserver:false,
      proxy:{
        "/":{
          target: process.env.vue_app_interface,
          changeorigin:true,
          pathrewrite:{
            "^/":"/"
          }
        }
      }
    },

    transpiledependencies: true,
    publicpath: './',
    // 输出文件目录
    assetsdir: 'static',
    outputdir: process.env.outputdir,
    // eslint-loader 是否在保存的时候检查
    lintonsave: true,
    
    // 生产环境是否生成 sourcemap 文件
    productionsourcemap: false
})

以上就是全部代码，如果安装不了electron，或是安装后运行不起来，改一下npm镜像源试试，package-lock.json这个文件记得删除。
