下载demo参考如下，需要在module.json5配置如下权限

‘requestPermissions’: [
{“name”: “ohos.permission.INTERNET”},
{“name”: “ohos.permission.WRITE_MEDIA”},
{“name”: “ohos.permission.READ_NEDIA”}
],

import common from '@ohos.app.ability.common';
import request from '@ohos.request';
import { BusinessError } from '@ohos.base';

// 获取应用文件路径
let context = getContext(this) as common.UIAbilityContext;
let filesDir = context.filesDir;

@Entry
@Component
export struct Index1 {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        Button("下载")
        .onClick(() => {
          try {
            console.log('downloadTask1 filesDir' + filesDir + '/00sg00izg2.jpg');
            //下载文件
            request.downloadFile(context, {
              url: 'https://xxx.jpg',
              filePath: filesDir + '/00sg00izg2.jpg'
            }).then((downloadTask: request.DownloadTask) => {
              //开启回调
              downloadTask.on('complete', () => {
                console.info('downloadTask1 complete');
