How to use the qiniu.rsf function in qiniu

const qiniuRsf = qiniu.rsf
const client   = new qiniuRs.Client()

class Qiniu {

      this.accessKey = accessKey
      this.secretKey = secretKey

      qiniu.conf.ACCESS_KEY = this.accessKey.toString(crypto.enc.Utf8)
      qiniu.conf.SECRET_KEY = this.secretKey.toString(crypto.enc.Utf8)
   }

   uploadFiles(uploadingPath, options) {
      console.log('---------------------------')
      glob.sync(uploadingPath, {
         nodir: options.nodir,

function qiniuList() {

        console.log(item.key);
      });
    } else {
      console.log(err)
    }
  });
