我使用以下代码使用itextsharp

将div内容导出为pdf格式

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
// Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
Document pdfDoc = new Document(new Rectangle(1000f, 1000f));
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();

它显示以下错误

    @staticmethod
    def post(request, *args, **kwargs):
        form = forms.input_form(request.POST)

        if form.is_valid():
            # process the data
            .....
         
            # Generate the mp3 file at ./speech.mp3
            amazon_polly.amazon_polly(....)

            return http.JsonResponse({}, status=200)
        else:
            return http.JsonResponse({}, status=400)
