https://www.cnblogs.com/louby/p/905198.html转自,看文章只放了代码看起来云里雾里的,在此做些解析
使用说明:
1.首先呢,得安装下软件,地址下面有链接,文件里有使用说明
2.代码里安装路径得改下,改成你安装的路径,或者把wkhtmltopdf.exe 文件放在网站bin目录下
3.设置下输出路径,转好的pdf得有地方存,代码里是放在了D盘,可以变动
4.就可以使用啦,直接调用HtmlToPdf(string url) url为要转的html路径。
一、转换程序代码如下:
public string 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 = "1.pdf"; //string path = Server.MapPath("~/kehu/" + dwbh + "/pdf/") + pdfName; string path = "D:\" + pdfName; try { if (string.IsNullOrEmpty(url) || string.IsNullOrEmpty(path)) success = false; //获取安装路径 string str = Server.MapPath("~\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; } return ""; }
