electron初学之随机点名

最近学了下electron，实践下也弄个exe安装程序。

思路：按照每个班级提供一个表格，读取表格中姓名列内容，存储一下。点名时选择班级，对班级人员随机展示，实现点名

主要配置

async function createWindow() {// Create the browser window.const win = new BrowserWindow({width: 800,height: 600,webPreferences: {webSecurity: false, //取消跨域限制// Use pluginOptions.nodeIntegration, leave this alone// See nklayman.github.io/vue-cli-plugin-electron-builder/guide/security.html#node-integration for more infonodeIntegration: process.env.ELECTRON_NODE_INTEGRATION,contextIsolation: !process.env.ELECTRON_NODE_INTEGRATION,enableRemoteModule: true},// eslint-disable-next-line no-undeficon: `${__static}/ept.ico`,// titleBarStyle: "hidden-inset", //隐藏标题栏autoHideMenuBar: true, //隐藏菜单栏//frame: false, //无边框// titleBarOverlay: true, //显示关闭最大化最小化resizable: false, //是否可以改变窗口size，默认为 true.});if (process.env.WEBPACK_DEV_SERVER_URL) {// Load the url of the dev server if in development modeawait win.loadURL(process.env.WEBPACK_DEV_SERVER_URL);if (!process.env.IS_TEST) win.webContents.openDevTools();} else {createProtocol("app");// Load the index.html when not in developmentwin.loadURL("app://./index.html");}
}// 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 + Qif (process.platform !== "darwin") {app.quit();}// 生产模式下在关闭electron时，启动stop.bat把java进程也关闭if (isCopyLib && !isDevelopment) {shell.openPath(path.resolve() + "\\resources\\lib\\stop.bat");}
});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();
});// 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", async () => {//生产模式下启动时打开运行bat启动java进程if (isCopyLib && !isDevelopment) {shell.openPath(path.resolve() + "\\resources\\lib\\run.bat");}createWindow();
});

pluginOptions: {electronBuilder: {nodeIntegration: true,contextIsolation: false,enableRemoteModule: true,builderOptions: {appId: "com.example.app",productName: appName, //项目名，也是生成的安装文件名，即aDemo.execopyright: "Copyright © 2022 HiCB", //版权信息//打包时复制项目目录下的res中文文件到 打包后的exe所在目录的res文件夹中，文件夹下没有文件的话不会复制extraResources: isCopyLib ? [{"from": "./lib/","to": "../resources/lib"  }] : [],win: {//win相关配置icon: "./public/ept.ico", //图标，当前图标在根目录下，注意这里有两个坑target: [{target: "nsis", //利用nsis制作安装程序arch: ["x64", //64位"ia32"//32位],},],},nsis: {oneClick: false, // 是否一键安装allowElevation: true, // 允许请求提升。 如果为false，则用户必须使用提升的权限重新启动安装程序。allowToChangeInstallationDirectory: true, // 允许修改安装目录installerIcon: "./public/ept.ico", // 安装图标uninstallerIcon: "./public/ept.ico", //卸载图标installerHeaderIcon: "./public/ept.ico", // 安装时头部图标createDesktopShortcut: true, // 创建桌面图标createStartMenuShortcut: true, // 创建开始菜单图标shortcutName: appName, // 图标名称},},},},

读取表格中的姓名列，并进行存储

  readExcel1(file) {let that = this;if (!/\.(xls|xlsx)$/.test(file.name.toLowerCase())) {this.$message.error("上传格式不正确，请上传xls或者xlsx格式");this.clearFiles();return false;}const fileReader = new FileReader();fileReader.onload = (ev) => {try {const data = ev.target.result;const workbook = XLSX.read(data, {type: "binary",});let name = file.name;that.fileName = name.substring(0, name.indexOf("."));that.readData(workbook);} catch (e) {return false;} finally {that.clearFiles();}};fileReader.readAsBinaryString(file);},readData(workbook) {const wsname = workbook.SheetNames[0]; //取第一张表const ws = XLSX.utils.sheet_to_json(workbook.Sheets[wsname], {range: 0,}); //生成json表格内容,从第一行开始（可以忽略标题）this.rawData = ws;let arr = [];for (let i = 0; i < ws.length; i++) {let item = ws[i]["姓名"];if (!isEmpty(item)) {arr.push(item);}}if (arr.length > 0) {let key = "myusers." + this.fileName;this.$setStoreData(key, arr);this.$emit("upload-success", ws);this.$baseMessage("数据上传成功","success",false,"vab-hey-message-success");} else {this.$baseMessage("未读取到【姓名】列,请检查是否存在【姓名】列并且是从第一行开始","error",false,"vab-hey-message-error");}},

按班级读取文件，随机点名

 handleStart() {if (this.users.length > 0) {this.sign = !this.sign;if (this.timer) {clearInterval(this.timer);this.timer = "";// this.voicePrompt(this.user);} else {let that = this;this.timer = setInterval(() => {let index = that.randomNum(0, that.users.length - 1);that.user = that.users[index];}, 10);}} else {this.$baseMessage("请先选择班级！","error",false,"vab-hey-message-error");}},//生成从minNum到maxNum的随机数randomNum(minNum, maxNum) {switch (arguments.length) {case 1:return parseInt(Math.random() * minNum + 1, 10);case 2:return parseInt(Math.random() * (maxNum - minNum + 1) + minNum, 10);default:return 0;}},
