使用共享访问签名的Azure ZIP多个文件并从流中下载

我正在使用 DotNetZip 用于将Blob压缩(或尝试至少).

I'm using Shared Access Signatures for downloading blobs from my blobstorage and DotNetZip for zipping the blobs, (or trying atleast).

   var images = _fileService.GetImages(companyID, model.ImageIDs).ToList();

        if (images != null && images.Count > 0)
        {
            DateTime currentTime = TimeZoneExtensions.GetCurrentDate();

            using (ZipFile zip = new ZipFile())
            {
                MemoryStream output = new MemoryStream();

                foreach (var image in images)
                {
                    if (image.ImageLinks != null)
                    {
                        //ImageLinks contains SAS uri for each image format..
                        List<ImageLinkModel> imageLinks = image.ImageLinks.Where(m => m.FormatID == model.FormatID).ToList();

                        if (imageLinks != null && imageLinks.Count > 0)
                        {
                            foreach (var imageLink in imageLinks)
                            {
                                if (String.IsNullOrEmpty(imageLink.DownloadURL) || imageLink.DateExpiresDownloadURL < currentTime)
                                {
                                    int hours = 1;

                                    imageLink.DateExpiresDownloadURL = currentTime.AddHours(hours);

                                    //Create new shared access signature
                                    imageLink.DownloadURL = _fileService.GetDownloadImageURL(imageLink.BlobName, image.ImageName, hours);

                                    //Update imagelink
                                    _fileService.UpdateImageLink(companyID, imageLink);

                                    //Exception here
                                    zip.AddDirectory(imageLink.DownloadURL);
                                }
                                else
                                {

                                    //Use existing SAS download url

                                    Exception here
                                    zip.AddDirectory(imageLink.DownloadURL);
                                }
                            }

                            zip.Save(output);
                        }
                    }
                }

                return File(output, "application/zip", "sample.zip");
            }
        }

这是我到目前为止提出的.

This is what I have come up with so far.

运行此方法并将文件添加到zip时，出现异常: System.ArgumentException不支持URI格式.我认为您只能将本地路径添加到zip中，这很有意义，所以现在我没有主意了.

When running this method and adding a file to the zip I get the exception: System.ArgumentException URI format not supported. I assume you can only add local path to the zip which makes sense, so now I'm out of ideas.

这是我的SAS URL之一:

This is one of my SAS URLs:

URL没什么问题，(我无需压缩即可下载).

It's nothing wrong with the URL, (I can download without zipping).

我要在这里做不可能的事吗?我是否被迫按此的常规方式下载Blob?然后将它们拉上拉链?

Am I trying to do the impossible here? Am I forced to download the blobs the normal way like this and after that zip them?

谢谢
