我需要一个应用程序的

Question

页面

PDFkit的准确PDF或图片没有得到根本<div>元素，IMGkit呈现空白图像（以下法）：

def png 
    file = Tempfile.new(Digest::MD5.hexdigest(rand(12).to_s), :encoding => 'ascii-8bit') 
    file.write(IMGKit.new(request.referer).to_png) 
    send_data file, :filename => "test.png" 
end 

是否有可靠的获得副本应用中的任何给定页面？格式并不重要，但PDF将是理想的。

Answer 1

尝试

kit = IMGKit.new(request.referer, height: 900, transparent:true, quality:10) /*YOUR SETTING*/ 

file = kit.to_file(Rails.root + "public/pngs/" + "screenshot.png") /*YOUR IMAGE NAME*/ 
send_file("#{Rails.root}/public/pngs/screenshot.png", :filename => "screenshot.png", :type => "image/png",:disposition => 'attachment',:streaming=> 'true') /*YOUR ADDRESS WHERE U WANT TO STORE PNG FILE*/
