C#编写 HTML生成PDF
原创
html中
<body> <div style="text-align:center;"> <iframe id="pdframe" width="900px;" height="850px;" name="pdframe" src="../dl/NOQRS.htm" frameborder="no" border="0" marginwidth="0" marginheight="0" scrolling="no" allowtransparency="yes"> </iframe> </div> <br /> <table border="0" align="center" cellpadding="0" cellspacing="0" class="wd noprint"> <tr> <td align="right" height="30"> </td> </tr> <tr> <td align="right" height="50"> <a id="dc_a" class="dc" href="javascrpit:void(0)" target="_blank"> <img src="../../images/dc.jpg" border="0" width="128" height="43" /></a> <a id="dy_a" class="dy" href="javascrpit:void(0)" onclick="dyqrs()"> <img src="../../images/dy.jpg" border="0" width="128" height="43" /></a> </td> </tr> </table> </body>
js里面：
$(function () { $.ajax({ type: "GET", url: "/DLGL/GetDLZWQRSBH", cache: false, dataType: "json", success: function (data) { if (data.success) { var s = "../DL/DL_ZWFYQRSPDF.htm?dwbh=" + data.dwbh; var ss = "/Tools/HtmlToPdf?url=DL/DL_ZWFYQRSPDF.htm?dwbh=" + data.dwbh; $("#pdframe").attr("src", s); $("#dc_a").attr("href", ss); } } }); }); function dyqrs() { window.print(); }
控制器中
public JsonResult HtmlToPdf(string url) {
bool success = true;
string dwbh = url.Split('?')[1].Split('=')[1];
//CommonBllHelper.CreateUserDir(dwbh);
url = Request.Url.Host + "/html/" + url;
string guid = DateTime.Now.ToString("yyyyMMddhhmmss");
string pdfName = guid + ".pdf";
//string path = Server.MapPath("~/kehu/" + dwbh + "/pdf/") + pdfName;
string path = "D:\Temp\" + pdfName;
try
{
if (string.IsNullOrEmpty(url) || string.IsNullOrEmpty(path))
success = false;
string str = Server.MapPath("~\tools\wkhtmltopdf\bin\wkhtmltopdf.exe");
Process p = System.Diagnostics.Process.Start(str, url + " " + path);
p.WaitForExit();
if (!System.IO.File.Exists(str))
success = false;
if (System.IO.File.Exists(path))
{
FileStream fs = new FileStream(path, FileMode.Open);
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
if (Request.UserAgent != null)
{
string userAgent = Request.UserAgent.ToUpper();
if (userAgent.IndexOf("FIREFOX", StringComparison.Ordinal) <= 0)
{
Response.AddHeader("Content-Disposition",
"attachment; filename=" + HttpUtility.UrlEncode(pdfName, Encoding.UTF8));
}
else
{
Response.AddHeader("Content-Disposition", "attachment; filename=" + pdfName);
}
}
Response.ContentEncoding = Encoding.UTF8;
Response.ContentType = "application/octet-stream";
//通知浏览器下载文件而不是打开
Response.BinaryWrite(bytes);
Response.Flush();
Response.End();
fs.Close();
System.IO.File.Delete(path);
}
else
{
Response.Write("文件未找到,可能已经被删除");
Response.Flush();
Response.End();
}
}
catch (Exception ex)
{
success = false;
}
var rlt = new { success = success };
return Json(rlt, JsonRequestBehavior.AllowGet);
}
