使用Electron获取用户信息，监听程序打开，用户退出连接关闭程序【全代码，有图】
效果图
如有其他操作可在代码中自己添加
main.js
const { app, BrowserWindow, ipcMain } = require('electron');
const path = require('node:path');
const os = require('os');
const { exec } = require('child_process');let intervalId;const createWindow = () => {const win = new BrowserWindow({width: 800,height: 600,autoHideMenuBar: true,webPreferences: {preload: path.join(__dirname, 'preload.js'),}});win.loadFile('view/index.html');// 确保窗口完全加载后发送用户信息win.once('ready-to-show', () => {LogsInUser(win); // 发送登录用户信息});
};app.on('window-all-closed', () => {if (process.platform !== 'darwin') app.quit();
});app.whenReady().then(() => {// 订阅消息ipcMain.handle('getWindowsUser', getWindowsUser);createWindow();app.on('activate', () => {if (BrowserWindow.getAllWindows().length === 0) createWindow();});// 每 5 秒获取登录用户信息startUserCheck();
});function getWindowsUser() {const userDomain = process.env.USERDOMAIN || 'UNKNOWN_DOMAIN';//用于获取当前用户的域名或工作组名称const username = os.userInfo().username; // 获取用户名return `${userDomain}---${username}`; // 返回域账号格式
}function LogsInUser(win) {if (win) {// 将用户信息发送到前端win.webContents.send('LogsInUser', os.userInfo().username);};
}// 启动用户检查函数，每 5 秒执行一次
function startUserCheck() {intervalId = setInterval(() => {// 每次检查获取当前登录的用户getLoggedInUsers();}, 5000);
}// 获取当前登录用户信息并判断其状态
function getLoggedInUsers() {const username = os.userInfo().username;// 如果 username 为空，退出程序if (!username) {console.log('Username is empty, exiting...');clearInterval(intervalId);app.quit();return;}// 使用 Windows 命令检查用户是否连接checkUserConnection(username, (isConnected) => {if (!isConnected) {console.log(`${username} is disconnected, exiting...`);clearInterval(intervalId);app.quit();} else {console.log(`Logged in user: ${username} is still connected`);const win = BrowserWindow.getAllWindows()[0];if (win) {win.webContents.send('userLoggedIn', username);}}});
}// 使用 Windows 命令行检查当前用户连接状态
function checkUserConnection(username, callback) {exec('chcp 65001 && qwinsta', { encoding: 'utf8' }, (error, stdout, stderr) => {if (error || stderr) {return callback(false); // 如果出错，认为用户断开}// 去除 stdout 中的多余空格和换行符const cleanedStdout = stdout.replace(/\s+/g, ' ').trim();// 正则表达式匹配当前用户的行，查找状态为 "Active" 或 "Disc" 的用户const userPattern = new RegExp(`(\\S+)\\s+(${username})\\s+\\d+\\s+(Active|Disc|Disconnected)`, 'i');const matches = cleanedStdout.match(userPattern);if (matches && matches[3] === 'Active') {callback(true); // 如果用户是活跃状态} else {callback(false); // 否则认为用户断开}});
}preload.js
const { contextBridge,ipcRenderer } = require('electron')contextBridge.exposeInMainWorld('myApi', {getWindowsUser: () => {return ipcRenderer.invoke('getWindowsUser')},userLoggedIn: (callback) => {ipcRenderer.on('userLoggedIn', (event, data) => {callback(data);});},LogsInUser: (callback) => {ipcRenderer.on('LogsInUser', (event, data) => {callback(data);});}
