Question

我正在使用EVO pdf DLL。我已经完成了与pdf相关的所有功能。有谁知道如何保存生成的PDF而不是下载。

这是我的代码我可以将该文件保存到我的位置，但 txt 格式文件正在生成。

这是我的代码

如果我做错了，请纠正我。

 httpResponse.AddHeader("Content-Disposition", String.Format("attachment; filename='" + purchase_order_number + "'.pdf; size={0}", pdfBytes.Length.ToString()));

 pdfConverter.SavePdfFromUrlToFile(host + "/pdf-purchase-order/Default.aspx/?in=" + purchase_order_number + "&vid=" + vendor_id + "&wid=" + WarehouseAddress, Server.MapPath("../backup111/"+purchase_order_number+".pdf"));

Answer 1

如果您使用html创建pdf，则可以使用以下

SavePdfFromHtmlStringToFile(html, "PATH_TO_FILE");

我们确实需要更多信息才能给您答案。

Answer 2

正如您所说，您成功生成了pdf，这意味着您可以在服务器上看到该pdf，然后您可以通过此代码将其保存在客户端计算机上

Response.ContentType = "Application/pdf"; 
 Response.AppendHeader("Content-Disposition", "attachment; filename=Test_PDF.pdf"); 
 Response.TransmitFile(Server.MapPath("~/Files/Test_PDF.pdf")); 
 Response.End();

Here是一个完整的演示。

如果您使用的是evohtmltopdf.dll，则可以使用此功能：

        int packet_size = packet.size();
        JBuffer packet_buf = packet;  

        byte[] data = packet_buf.getByteArray(0, packet_size);
        int[] data_int = new int[max_byte_read];

        for (int k = 0; k<max_byte_read; k++) {
           data_int[k] = data[k]&0xFF;
        }

        byte[] frame_control = new byte[2];
        byte[] duration = new byte[2];
        byte[] dest_ip = new byte[6];
        byte[] src_ip = new byte[6];
        byte[] bss_id = new byte[6];
        byte[] seq_ctrl = new byte[2];
        byte[] time_stamp = new byte[8];
        byte[] beacon_interval = new byte[2];
        byte[] capability_info = new byte[2];
        byte[] tag_nr = new byte[1];
        byte[] tag_len = new byte[1];

         if (data_int[0]==0x80) {
            // It's a beacon
            System.out.printf("It's a beacon!\n");
            frame_control = Arrays.copyOfRange(data, 0, 2);
            duration = Arrays.copyOfRange(data, 2, 4);
            dest_ip = Arrays.copyOfRange(data, 4, 10);
            src_ip = Arrays.copyOfRange(data, 10, 16);
            bss_id = Arrays.copyOfRange(data, 16, 22);
            seq_ctrl = Arrays.copyOfRange(data, 22, 24);
            time_stamp = Arrays.copyOfRange(data, 24, 32);
            beacon_interval = Arrays.copyOfRange(data, 32, 34);
            capability_info = Arrays.copyOfRange(data, 34, 36);
            tag_nr = Arrays.copyOfRange(data, 36, 37);
            tag_len = Arrays.copyOfRange(data, 37, 38);

            int ss_id_len = tag_len[0];

            byte[] ss_id = new byte[ss_id_len];

            ss_id = Arrays.copyOfRange(data, 38, 38+ss_id_len);

            System.out.printf("SSID: ");
            for (byte b : ss_id) {
                int c = b&0xFF;
                System.out.printf("%s", (char) c);    
            }
            System.out.println("");
        }
        else {
            System.out.println("Not a beacon unfortunately");
        }
