HarmonyOS 文件上传 & 资源读取问题

let uploadTask: request.UploadTask; 
let uploadConfig: request.UploadConfig = { 
  url: 'http://www.huawei.com', //需要手动替换为真实服务器地址 
  header: { 'Accept': '*/*' }, 
  method: "POST", 
  files: [{ filename: "test", name: "test", uri: "internal://cache/test.jpg", type: "jpg" }], 
  data: [{ name: "name123", value: "123" }], 
}; 
try { 
  request.uploadFile(getContext(), uploadConfig).then((data: request.UploadTask) => { 
    uploadTask = data; 
  }).catch((err: BusinessError) => { 
    console.error(`Failed to request the upload. Code: ${err.code}, message: ${err.message}`); 
  }); 
} catch (err) { 
  console.error(`Failed to request the upload. err: ${JSON.stringify(err)}`); 
}

files中的uri可以读取工程内的资源文件吗，例如resources下的资源($r(‘app.media.ic_app_logo’))，这样怎么读取并上传？

request当前仅支持上传应用沙箱路径的文件，需要上传项目资源文件，请先拷贝到沙箱路径，以下是一个拷贝rawfile下资源文件的参考:

getContext(this).resourceManager.getRawFileContent('test.txt', (_err, value) => { 
  let myBuffer:ArrayBufferLike = value.buffer 
  let context = getContext(this); 
  //沙箱路径 
  let filePath = context.filesDir + "/test.txt"; 
  console.log("testTag-filePath:" + filePath); 
  let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE); 
  let writeLen = fs.writeSync(file.fd, myBuffer); 
  console.info("testTag-write data to file succeed and size is:" + writeLen); 
  fs.closeSync(file); 
});
