可以使用安全控件中的保存控件，免去权限申请和权限请求等环节，获得临时授权，保存对应图片。需要申请权限：ohos.permission.INTERNET。参考代码如下：

import {
    http } from '@kit.NetworkKit';
import {
    image } from '@kit.ImageKit';
import {
    BusinessError } from '@kit.BasicServicesKit';
import {
    photoAccessHelper } from '@kit.MediaLibraryKit';
import {
    promptAction } from '@kit.ArkUI';
import {
    fileIo as fs } from '@kit.CoreFileKit';

@Entry
@Component
struct SaveImage {
   
  @State pixelMap: PixelMap | undefined = undefined;

  loadImageWithUrl(url: string) {
   
    let responseCode = http.ResponseCode;
    let OutData: http.HttpResponse;
    let imagePackerApi = image.createImagePacker();
    let packOpts: image.PackingOption = {
    format: 'image/jpeg', quality: 98 };
    // 确保网络正常
    http.createHttp().request(url, {
   
      method: http.RequestMethod.GET,
