#鸿蒙通关秘籍#如何在HarmonyOS NEXT中下载文件并监听进度

使用request模块下载文件，并监听其进度和完成事件：

import { request } from '@kit.BasicServicesKit';

function downloadFile(url, filePath) {
  const downloadConfig = {
    url: url,
    filePath: filePath,
    enableMetered: true,
  };

  request.downloadFile(downloadConfig).then((downloadTask) => {
    downloadTask.on('progress', (receivedSize, totalSize) => {
      console.info(`Download progress: ${receivedSize} of ${totalSize}`);
    });

    downloadTask.on('complete', () => {
      console.info('Download completed');
    });
  }).catch((error) => {
    console.error('Download failed', error);
  });
}
