PDFKit 的保存按钮？

Question

是否可以使用 PDFkit 添加保存按钮以下载 pdf 格式？

file = kit.to_file('/path/to/save/pdf')

我在 Github 上看到了这个，但我不知道按下按钮时该怎么做，下载将在浏览器中启动

谢谢

您必须使用以下 link https://github.com/devongovett/pdfkit

# require dependencies
PDFDocument = require 'pdfkit'
blobStream  = require 'blob-stream'

# create a document the same way as above
doc = new PDFDocument

# pipe the document to a blob
stream = doc.pipe(blobStream())

# add your content to the document here, as usual

# get a blob when you're done
doc.end()
stream.on 'finish', ->
# get a blob you can do whatever you like with
blob = stream.toBlob('application/pdf')

# or get a blob URL for display in the browser
url = stream.toBlobURL('application/pdf')
iframe.src = url

Above code write document into stream ( memory ), once finish stream put into blobStream and then generate url and show in iframe.

When user click button, redirect to url, so they can download already
