HarmonyOS 鸿蒙Next 使用相机拍照或者相册选择照片并把照片上传到服务器

上传是需要用internal://cache/xxx.jpg 这个路径的

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

算了，上代码吧：

// 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)

          })

      }

    }

  }

}
