Javascript 谷歌页面没有出现在我的电子应用程序中

我正在使用eletron框架制作桌面应用程序，我需要在其中显示google搜索页面。 当我尝试在我的项目中显示普通html页面时，它看起来没有问题。但当我尝试使用在线网站时，它并没有出现。我需要知道我是否做错了什么，我只是遵循了一个教程

// Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron')
const path = require('path')


function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 1200,
    height: 600,
  })

  // and load the index.html of the app.
  mainWindow.loadFile(`https://google.com`)
}

// 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()
  
  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 (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', function () {
  if (process.platform !== 'darwin') 
     app.quit()
})

使用“loadURL”而不是“loadFile”，可以找到更多信息
