How do I download a file over HTTP using Ruby?
506
Plain old Ruby The most popular way to download a file without any dependencies is to use the standard library open-uri . open-uri extends Kernel#open so that it can open URIs as if they were files. We can use this to download an image and then save it as a file.
In general, downloading a file from an HTTP server terminal via HTTP GET consists of the following steps: Make an HTTP GET request to send to the HTTP server. Send an HTTP request and receive an HTTP response from the HTTP server. Save the contents of the HTTP response file to a local file.
For Example: i Have my file in SVG folder inside Public Directory. Now we Can Access any file in Public Folder Like below and Pass id and Download option. Download option rename any file which u want to download. Now Click able link is Ready We Can Click on Above link to Download the File.
Probably the shortest way to download a file:
require 'open-uri' download = open('http://example.com/download.pdf') IO.copy_stream(download, '~/my_file.pdf') You can use open-uri, which is a one liner
require 'open-uri' content = open('http://example.com').read If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
