将生成的PDF文件保存为Azure [英] Save generated PDF file in azure

问题描述

我在ASP.NET中有一个表单，在最后一步中填写表单时，它会生成PDF文件.我使用了jsPDF. 我想要的是，生成的pdf文件要在Azure存储中发送(保存)，有人可以帮助我吗?

I have a form in ASP.NET and in when I fill up the form in the last step it generates a PDF file. I used jsPDF. What I want is that, the generated pdf file to be send (saved) in Azure storage, does anyone can help me?

谢谢

更新:这是我正在尝试的代码，它可以正常工作，但仅提取文本，不会按原样保存pdf:

UPDATE: This is the code that I'm trying, it's working but it's extracting only the text, it doesn't save the pdf as it is:

var account = new CloudStorageAccount(new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials("storageaccount", 
                    "accesskey"), true);
var blobClient = account.CreateCloudBlobClient();
var container = blobClient.GetContainerReference("folderpath");

StringBuilder text = new StringBuilder();
string filePath = "C:\\Users\\username\\Desktop\\toPDF\\testing PDFs\\test.pdf";

if (File.Exists(filePath))
{
     PdfReader pdfReader = new PdfReader(filePath);

     for (int page = 1; page <= pdfReader.NumberOfPages; page++)
     {
         ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
         string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy);
         currentText = Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(currentText)));
         text.Append(currentText);
       }
       pdfReader.Close();

       using (MemoryStream ms = new MemoryStream())
       {
       using (var doc = new iTextSharp.text.Document())
       {
             PdfWriter writer = PdfWriter.GetInstance(doc, ms);
             doc.Open();
             doc.Add(new Paragraph(text.ToString()));
       }
       var byteArray = ms.ToArray();
       var blobName = "test.pdf";
       var blob = container.GetBlockBlobReference(blobName);
       blob.Properties.ContentType = "application/pdf";
       blob.UploadFromByteArray(byteArray, 0, byteArray.Length);
       }
    } 

推荐答案

我找到了一个简单的解决方案，这就是代码的作用:

I found a simple solution, this is what the code does:

string filePath = "C:\\Users\\username\\Desktop\\toPDF\\testing PDFs\\rpa.pdf";
var credentials = new StorageCredentials("storageaccount","accesskey");
var client = new CloudBlobClient(new Uri("https://jpllanatest.blob.core.windows.net/"), credentials);

// Retrieve a reference to a container. (You need to create one using the mangement portal, or call container.CreateIfNotExists())
var container = client.GetContainerReference("folderpath");
// Retrieve reference to a blob named "myfile.pdf".
var blockBlob = container.GetBlockBlobReference("myfile.pdf");

// Create or overwrite the "myblob" blob with contents from a local file.
using (var fileStream = System.IO.File.OpenRead(filePath))
{
     blockBlob.UploadFromStream(fileStream);
}
