Rotativa pdf在發佈到Azure服務器時不起作用

Question

我有一個帶有Asp.net MVC 5的Web應用程序，我使用了Rotativa作爲pdf。

Rotativa在發佈到Azure Server時無法正常工作，但它適用於本地計算機。 它給出了波紋管錯誤

500 - 請求定時。

Web服務器在指定的時間內未能響應。

貝婁是我的代碼。

public ActionResult DoPdf(int id) 
{ 
return new ActionAsPdf("PrintMyPdf", new { id = id }) { FileName = string.Format("Demo_{0}.pdf", id) }; 
} 

這裏是已經被發現無法使用，由於限制byAzure Web應用程序沙箱 https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#unsupported-frameworks

請建議我該怎麼辦我的HTML視圖的PDF在框架和方案的列表MVC 5？

我建議您使用EvoPdf的HTML to PDF for Azure Websites。您可以完全控制HTML到PDF Azure雲服務，因爲您是該服務的所有者，您不必擔心諸如發送用於轉換的數據的安全性。您在網站上使用的代碼如下所示：

protected void convertToPdfButton_Click(object sender, EventArgs e) 
{ 
    // Get the server IP and port 
    String serverIP = textBoxServerIP.Text; 
    uint serverPort = uint.Parse(textBoxServerPort.Text); 

    // Create a HTML to PDF converter object with default settings 
    HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(serverIP, serverPort); 

    // Set optional service password 
    if (textBoxServicePassword.Text.Length > 0) 
     htmlToPdfConverter.ServicePassword = textBoxServicePassword.Text; 

    // Set HTML Viewer width in pixels which is the equivalent in converter of the browser window width 
    htmlToPdfConverter.HtmlViewerWidth = int.Parse(htmlViewerWidthTextBox.Text); 

    // Set HTML viewer height in pixels to convert the top part of a HTML page 
    // Leave it not set to convert the entire HTML 
    if (htmlViewerHeightTextBox.Text.Length > 0) 
     htmlToPdfConverter.HtmlViewerHeight = int.Parse(htmlViewerHeightTextBox.Text); 

    // Set PDF page size which can be a predefined size like A4 or a custom size in points 
    // Leave it not set to have a default A4 PDF page 
    htmlToPdfConverter.PdfDocumentOptions.PdfPageSize = SelectedPdfPageSize(); 

    // Set PDF page orientation to Portrait or Landscape 
    // Leave it not set to have a default Portrait orientation for PDF page 
    htmlToPdfConverter.PdfDocumentOptions.PdfPageOrientation = SelectedPdfPageOrientation(); 

    // Set the maximum time in seconds to wait for HTML page to be loaded 
    // Leave it not set for a default 60 seconds maximum wait time 
    htmlToPdfConverter.NavigationTimeout = int.Parse(navigationTimeoutTextBox.Text); 

    // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed 
    // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish 
    if (conversionDelayTextBox.Text.Length > 0) 
     htmlToPdfConverter.ConversionDelay = int.Parse(conversionDelayTextBox.Text); 

    // The buffer to receive the generated PDF document 
    byte[] outPdfBuffer = null; 

    if (convertUrlRadioButton.Checked) 
    { 
     string url = urlTextBox.Text; 

     // Convert the HTML page given by an URL to a PDF document in a memory buffer 
     outPdfBuffer = htmlToPdfConverter.ConvertUrl(url); 
    } 
    else 
    { 
     string htmlString = htmlStringTextBox.Text; 
     string baseUrl = baseUrlTextBox.Text; 

     // Convert a HTML string with a base URL to a PDF document in a memory buffer 
     outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlString, baseUrl); 
    } 

    // Send the PDF as response to browser 

    // Set response content type 
    Response.AddHeader("Content-Type", "application/pdf"); 

    // Instruct the browser to open the PDF file as an attachment or inline 
    Response.AddHeader("Content-Disposition", String.Format("{0}; filename=Getting_Started.pdf; size={1}", 
     openInlineCheckBox.Checked ? "inline" : "attachment", outPdfBuffer.Length.ToString())); 

    // Write the PDF document buffer to HTTP response 
    Response.BinaryWrite(outPdfBuffer); 

    // End the HTTP response and stop the current page processing 
    Response.End(); 
}
