HarmonyOS 关于文件路径如何转化成internal://cache/格式

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：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-fileio-V5#ZH-CN_TOPIC_0000001930677245__fileiocopyfile

https://developer.huawei.com/consumer/cn/doc/harmonyos-guides/app-file-upload-download-0000001820880061

可参考以下demo：

// pages/xxx.ets
import common from '@ohos.app.ability.common';
import fs from '@ohos.file.fs';
import request from '@ohos.request';
import { BusinessError } from '@ohos.base';
import { photoAccessHelper } from '@kit.MediaLibraryKit';

// 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)
          })
      }
    }
  }
}
