多个文件上传，如何更新进度条

[ezewu]

  const callback = (taskList) => {
    $fetch("http://localhost:2800/task", { method: "post", body: taskList })
      .then((res) => {
        for (let i = 0; i < res.data.length; i++) {
          const ossData = res.data[i];
          const client = new OSS({
            region: ossData.regionId,
            accessKeyId: ossData.accessKeyId,
            accessKeySecret: ossData.accessKeySecret,
            stsToken: ossData.securityToken,
            bucket: ossData.bucketName,
          });



          //进度条数组

          updateFileList.value.push({
            name: ossData.path,
            fileName: taskList[i].fileName,
            fileSize: taskList[i].fileSize,
            progress: 0,
          });

          const progress = (progress, checkpoint) => {};

          client
            .multipartUpload(ossData.path, fileMap[ossData.fileId], {
              partSize: 1024 * 1024,
              progress,
            })
            .then((res) => {})
            .catch((e) => {});
        }
      })
      .catch((e) => {});
  };
