To generate a PDF with the contents of the URL:

url = "Http://www.baidu.com"
Kit = pdfkit.new (URL)
# kit.stylesheets << ' #{rails.root}/app/assets/assets/stylesheets/pdf.css ' # CSS styles are not available when using URLs.
#kit. to_pdf # inline PDF
#kit. To_file ('/path/pdf.pdf ')
Send_data (kit.to_pdf,: filename = "mypdf.pdf",: type = "Application/pdf")
