文件上传的实现，有人知道怎么处理吗？

import { BusinessError, request } from '@kit.BasicServicesKit';

let uploadTask: request.UploadTask;
let uploadConfig: request.UploadConfig = {
  url: 'http://www.mywebsite.com', //替换真实的地址
  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;
    uploadTask.on("progress", (uploadedSize: number, totalSize: number) => {
          //监听上传进度
    })
    uploadTask.on("complete", (taskStates) => {
          //上传完毕
    })
    //。。。。。其他状态的监听

  }).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)}`);
}
