我正在使用 Google-Cloud-Storage。此代码将在存储桶中保存一个对象，但它只是空的。它显示的大小为 0 字节

req.file = req.files.file;
const bucketName = req.body.bucketName || DEFAULT_BUCKET_NAME;
const bucket = storage.bucket(bucketName);
const gcsFileName = `${Date.now()}-${req.file.name}`;
const file = bucket.file(gcsFileName);
const stream = file.createWriteStream({
  // resumable: false, 
  // gzip: true,
  metadata: {
      contentType: req.file.mimetype,
    },
});

stream.on('error', (err) => {
  req.file.cloudStorageError = err;
    next(err)
});
stream.on('finish', () => {
    console.log('image uploaded succesfully')
    req.file.cloudStorageObject = gcsFileName;
  return file.makePublic()
    .then(() => {
      req.file.gcsUrl = gcsHelpers.getPublicUrl(bucketName, gcsFileName);
      next()
    });
});

stream.end(req.files.file.buffer);
