是否有一种方法可以让程序记住当用户关闭程序时打开的URL ?

Question

是否有办法让程序记住当用户关闭程序时哪个URL是打开的?例如，如果用户关闭应用程序，最后一个URL将被添加到loadURL。该程序适用于只能与触摸屏互动，不能离开特定网站的用户。我用的是windows 10和最新版本的电子操作系统。

// Modules to control application life and create native browser window.
const { app, BrowserWindow, Menu } = require("electron");
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow;
function createWindow() {
// Create the browser window.
mainWindow = new BrowserWindow({
width: 800,
height: 600,
frame: false,
webPreferences: {
preload: `${__dirname}/preload.js`
}
});
// The loadURL that loads if you start up the application.
mainWindow.loadURL("https://google.com");
// Emitted when the window is closed.
mainWindow.on("closed", function() {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
mainWindow = null;
});
}
// The toggleFullScreen function stated in the createMainMenu function.
function toggleFullscreen() {
if (mainWindow.isFullScreen()) {
mainWindow.setFullScreen(false);
} else {
mainWindow.setFullScreen(true);
}
}
function createMainMenu() {
const template = [
{
label: "Options",
submenu: 
[
{
label: "Quit",
accelerator: "CmdOrCtrl+Q",
click() {
app.quit();
}
},
{
label: 'Toggle full screen',
accelerator: 'CmdOrCtrl+F',
click: () => {
toggleFullscreen();
}
},
{
label: 'Toggle developer tools',
accelerator: 'CmdOrCtrl+I',
click(item, focusedWindow){
focusedWindow.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.on("ready", () => {
createWindow();
createMainMenu();
});
// Quit when all windows are closed.
app.on("window-all-closed", function() {
// On macOS it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q.
if (process.platform !== "darwin") {
app.quit();
}
});
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 (mainWindow === null) {
createWindow();
}
});
// 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.

您有两个选择。

首先，每次URL更改时，在呈现过程中使用LocalStorage。它将像在一个web应用程序中一样工作。

第二，每次URL更改，让它发送一条消息回主进程，并让它将该消息写入本地文件。getPath('appData')可用于获取可写入设置文件的操作系统特定目录
