Question

我想在下载更新时在我的电子应用程序内显示进度条。因此，我已经根据我的需要调整了电子制造商更新程序文档中的示例代码。

以下是我的main.ts的摘录：

function sendStatusToWindow(updateState: UpdateState) {
  log.info(updateState);
  win.webContents.send('message', updateState);
}

autoUpdater.on('checking-for-update', () => {
  sendStatusToWindow({ status: 'checking' });
});

autoUpdater.on('update-available', (info) => {
  sendStatusToWindow({ status: 'update-available' });
});

autoUpdater.on('update-not-available', (info) => {
  sendStatusToWindow({ status: 'current' });
});

autoUpdater.on('error', (err) => {
  sendStatusToWindow({ status: 'error', error: err });
});

autoUpdater.on('download-progress', (progressObj) => {
  log.info(progressObj);
  sendStatusToWindow({
    status: 'downloading',
    download: {
      bytesPerSecond: progressObj.bytesPerSecond,
      percent: progressObj.percent,
      transferred: progressObj.transferred,
      total: progressObj.total
    }
  });
});

autoUpdater.on('update-downloaded', (info) => {
  sendStatusToWindow({ status: 'completed' });
});

还有我的electronic-builder.json：

  "win": {
    "icon": "dist",
    "target": ["NSIS"],
    "publish": ["github"]
  }

除download-progress之外的所有事件都被调用我在做错什么吗？

在开发人员模式下，checkForUpdatesAndNotify不会触发任何操作。仅在打包时有效。如果在开发人员模式（electron-is-dev）中调用checkForUpdates，则应该获得下载事件。

电子更新程序下载进度事件未调用
