我有一个项目,要求从URL链接压缩多个文件。在我的Db中,我有pdf文件名,可以根据URL链接检查并压缩它们。因此,可以说我将其作为URL来源:www.example.com/folder/{pdf file name}
。我想将test1.zip
与其他其他zip文件一起压缩。即test1.zip, test2.zip, test3.zip
等
因此,我设法编写了代码来迭代URL链接。但是问题是我设法压缩了一个文件。但实际上,我想压缩多个文件。
我尝试了所有途径,但没有奏效。任何帮助表示赞赏!
这是一个有效的代码:
ASP.NET Core
[HttpGet("zipFiles")]
public IActionResult ZipPDFFiles()
{
//file names coming from db
var fileNames = _repo.GetFileNames();
foreach (var filesName in fileNames)
{
var urlLink = "https://example.com/folder/" + $"{filesName.PdfFileName}";
var net = new System.Net.WebClient();
var data = net.DownloadData(urlLink);
var file = $"{filesName.PdfFileName}";
var contentType = "application/zip";
string zippedFolderName = "Archive.zip";
using (MemoryStream ms = new MemoryStream())
{
using (var archive = new ZipArchive(ms, ZipArchiveMode.Create, true))
{
var zipArchiveEntry = archive.CreateEntry($"{file}", System.IO.Compression.CompressionLevel.Fastest);
using (var zipStream = zipArchiveEntry.Open()) zipStream.Write(data, 0, data.Length);
}
return File(ms.ToArray(), contentType, $"{zippedFolderName}");
}
}
return NotFound();
}
