如何将.aspx页面转换为pdf?而不使用网站中的url

本文关键字：网站 url pdf aspx 转换 | 更新日期: 2023-09-27 17:59:25

我需要从.aspx创建一个pdf，但不使用wkHtmlToPdf或iTextSharp，因为他们需要页面中的url，而它对我不起作用，因为我的网站有安全性，所以当我尝试打印网站时，它会将我发送到默认页面。

有人知道我该怎么做吗？

提前谢谢。

我使用EvoPdf，所以我的解决方案与您的不同，但我在使用表单身份验证的应用程序（vb.net）中遇到了同样的问题。我的解决方案如下。关键是将Pdf库的cookie设置为已验证帐户的cookie。

Private Sub uiPdf_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles uiPdf.Click
    Dim urlToConvert As String = "ExportPdf.aspx"
    '// get the html string for the report
    Dim htmlStringWriter As New System.IO.StringWriter()
    Server.Execute(urlToConvert, htmlStringWriter)
    Dim htmlCodeToConvert As String = htmlStringWriter.GetStringBuilder().ToString()
    htmlStringWriter.Close()

    '// Create the PDF converter. 
    Dim pdfConverter As New EvoPdf.HtmlToPdf.PdfConverter()
    '************
    'Add the cookie so we don't get bounced to the home page
    '************ 
    If Not Request.Cookies(System.Web.Security.FormsAuthentication.FormsCookieName) Is Nothing Then
        pdfConverter.HttpRequestCookies.Add(System.Web.Security.FormsAuthentication.FormsCookieName, Request.Cookies(System.Web.Security.FormsAuthentication.FormsCookieName).Value)
    End If
    '// set the license key - required
    pdfConverter.LicenseKey = ConfigurationManager.AppSettings("EvoPdfLicenseKey")
    '// set the converter options - optional
    '... code omitted
    '// be saved to a file or sent as a browser response
    Dim baseUrl As String = HttpContext.Current.Request.Url.AbsoluteUri
    Dim pdfBytes As Byte() = pdfConverter.GetPdfBytesFromHtmlString(htmlCodeToConvert, baseUrl)
    '// send the PDF document as a response to the browser for download
    Dim response As System.Web.HttpResponse = System.Web.HttpContext.Current.Response
    Response.Clear()
    Response.AddHeader("Content-Type", "application/pdf")
    response.AddHeader("Content-Disposition", String.Format("attachment; filename=GettingStarted.pdf; size={0}", pdfBytes.Length.ToString()))
    response.BinaryWrite(pdfBytes)
    response.End()

End Sub
