electron中報錯Not allowed to load local resource

const mainWindow = new BrowserWindow({
    webPreferences: {
      webSecurity: false
    }
 })

const startUrl =
    process.env.NODE_ENV === 'dev'
      ? 'http://localhost:3000'
      : path.join(__dirname, "/build/index.html");

mainWindow.loadURL(startUrl);
           

需要設定webSecurity: false。
