    Serving generated PDF/vCard from content

    Extending Umbraco and using the API
    Umbraco 7

    We are developing a site that needs PDF and vCard export of certain document types.

    For PDF,

    We use wkhtmltopdf and followed the instructions at https://github.com/ma1f/umbraco/blob/master/pdf.md.

    However I cannot get the pdf.cshtml file to actually load/run when the user visits say an Article page, but with pdf as the extension (or /pdf as the repo suggests).

    We don't want to use a paid package because it's too expensive and would rather solve this ourselves.

    Any help would be super useful :)

    The following is the code in the pdf.cshtml file:

    @inherits Umbraco.Web.Mvc.UmbracoTemplatePage
@using Umbraco.Core
@using Umbraco.Web
@{
    Layout = null;
    string PDF_CONVERTER = Server.MapPath("/App_data/wkhtmltopdf/wkhtmltopdf.exe");

    var filename = Model.Content.UrlName + ".pdf";
    var path = Server.MapPath("/App_Data/pdfs/" + filename);
    var url = Request.Url.Scheme + "://" + Request.Url.Host + Model.Content.Url;
    // Create directory if needed
    var di = new DirectoryInfo(Path.GetDirectoryName(path));
    if (!di.Exists){ di.Create(); }

    // Connect to process
    var process = new System.Diagnostics.Process();
    process.StartInfo.FileName = PDF_CONVERTER;
    process.StartInfo.Arguments = "-T 0 -R 0 -B 0 -L 0 --no-outline --disable-smart-shrinking " + url + " " + "\"" + path + "\"";
    process.Start();
    process.WaitForExit();

    Response.Clear();
    Response.AddHeader("content-disposition", "attachment; filename=" + filename);
    Response.ContentType = "application/pdf";
    Response.WriteFile(path);
    Response.Flush();
    Response.End();
}
