1. 主进程代码
在主进程中，使用 `os` 模块获取本机 IP 地址，并通过 `ipcMain` 将结果发送给渲染进程。
javascript">// main.jsconst { app, BrowserWindow, ipcMain } = require("electron");const os = require("os");function createWindow() {const win = new BrowserWindow({width: 800,height: 600,webPreferences: {nodeIntegration: true,contextBridge: true,},});win.loadFile("index.html");}app.whenReady().then(() => {createWindow();app.on("activate", () => {if (BrowserWindow.getAllWindows().length === 0) {createWindow();}});});// 获取本机 IP 地址的函数function getLocalIP() {let interfaces = os.networkInterfaces();for (let devName in interfaces) {let iface = interfaces[devName];for (let i = 0; i < iface.length; i++) {let alias = iface[i];if (alias.family === "IPv4" &&alias.address !== "127.0.0.1" &&!alias.internal) {return alias.address;}}}}// 监听渲染进程的请求ipcMain.on("get-ip-address", (event) => {const localIP = getLocalIP();event.reply("ip-address", localIP);});2. 渲染进程代码
在渲染进程中，使用 `ipcRenderer` 向主进程发送请求，并接收主进程返回的 IP 地址。
javascript"><!-- index.html --><!DOCTYPE html><html lang="en"><head><meta charset="UTF-8" /><title>Electron IP Address</title></head><body><button id="get-ip">获取本机 IP 地址</button><p id="ip-address"></p><script>const { ipcRenderer } = require("electron");const getIpButton = document.getElementById("get-ip");const ipAddressDisplay = document.getElementById("ip-address");getIpButton.onclick = () => {ipcRenderer.send("get-ip-address");};ipcRenderer.on("ip-address", (event, ip) => {ipAddressDisplay.textContent = ip;});</script></body></html>
