目前可以使用 fs.copyFile接口，来把文件拷贝到cache目录下再进行上传， 参考文档：

import common from '@ohos.app.ability.common';
import fs from '@ohos.file.fs';


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

@Entry
@Component
struct Index12 {
  @State message: string = 'Hello World';

  build() {
    Row() {
      Column() {
        Text(this.message).fontSize(50).fontWeight(FontWeight.Bold)
        Button('复制').onClick(async () => {
          let uri = 'file://media/Photo/5/IMG_1718353652_004/IMG_004.jpg';
          let file = fs.openSync(uri)
          console.log('-------file', file.name)
          fs.copyFileSync(file.fd, cacheDir + "/IMG_003.jpg")
          fs.closeSync(file)
          let file1 = fs.openSync(cacheDir + "/IMG_003.jpg")
          console.log('-------file1', file1.name)
        })
      }
    }
  }
