无论如何使用Node.js中的multer（multer s3）解压缩文件并将其上传到AWS S3

Question

这是我将文件上传到AWS S3的方式：

import cv2
import threading

class Video:
    def play(self):
        video = cv2.VideoCapture('small.mov')

        if video.isOpened() == True:
            cv2.namedWindow("The Video")
            cv2.moveWindow("The Video", 500,200)

        elif video.isOpened() == False:
            print('No Data For Loading Video')
            return 0

        while video.isOpened():
            _, frame = video.read()

            if _ == True:
                cv2.imshow("The Video",frame)

                if cv2.waitKey(10) & 0xff == 27:
                    break

            if _ == False :
                break

        cv2.destroyAllWindows()
        video.release()

def Load():
    v=Video()
    v.play()
    del v


t = threading.Thread(target = Load)
t.start() 

然后：

const config = (req) => {
  limits: { fileSize: 20000000 }, // 20 MB
  storage: multerS3({
    acl: 'public-read',
    bucket: `${Bucket}/${orderNumber}/orderFiles`,
    key(request, file, cb) {
      cb(null, `${file.originalname}`);
    },
    metadata(request, file, cb) {
      cb(null, {});
    },
    s3,
  }),
}

uploadFiles = async req => {
  try {
    const uploadOrder = multer(config(req)).array('files');

    return new Promise((resolve, reject) => {
      uploadOrder(req, {}, error => {
        const fileArray = req.files;
        let fileLocation;

        fileArray.forEach(file => {
          fileLocation = file.location;
        });

        resolve(fileArray[0].bucket);
      });
    });
  } catch (error) {
    return error;
  }
};

有什么方法可以检查文件是否为 zip ，然后可以解压缩zip的每个文件并将其上传到s3？ 我全神贯注于互联网，无法正常工作。
