下载pdf而不是在浏览器中显示 [英] Download pdf instead of showing it in the browser

问题描述

我正在Rails应用程序上使用pdfkit(我根据Ryan Bates railscast 进行了此操作) 目前，它正在浏览器中显示pdf.

I am using pdfkit on my rails application (I did this according to Ryan Bates railscast) Currently it's showing the pdf inside the browser.

如何下​​载pdf呢?

How can the pdf be downloaded instead ?

谢谢

感谢您的回复！

但是如何在控制器中创建pdf数据?

But how can I create the data of the pdf in the controller?

URL为.pdf时，会自动显示pdf.例如，当转到此链接时:

The pdf shows up automatically when the url has .pdf. for example when going to this link:

http://localhost:3000/home/index.pdf

它会在浏览器上自动打开页面的pdf版本(这是rails中间件设置).

It opens a pdf version of the the page automatically on the browser (it's a rails middleware setup).

推荐答案

尝试使用所有rails控制器都具有的 send_data 方法.

Try using the send_data method that all rails controllers have.

类似这样的东西:

# Generate a PDF document with information on the client and return it.
# The user will get the PDF as a file download.
def download_pdf
  send_data(generate_pdf, :filename => "my_file.pdf", :type => "application/pdf")
end
