C# wkhtmltopdf 将html转pdf(详解)

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, , bytes.Length);
fs.Close();
if (Request.UserAgent != null)
{
string userAgent = Request.UserAgent.ToUpper();
if (userAgent.IndexOf("FIREFOX", StringComparison.Ordinal) <= )
{
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 "";
}
