How do I open a web page and write it to a file in ruby?

Question

If I run a simple script using OpenURI, I can access a web page. The results get written to the terminal.

Normally I would use bash redirection to write the results to a file.

How do I use ruby to write the results of an OpenURI call to a file?

Answer 1

require 'open-uri'

open("file_to_write.html", "wb") do |file|
  URI.open("http://www.example.com/") do |uri|
     file.write(uri.read)
  end
end

Note: In Ruby < 2.5 you must use open(url) instead of URI.open(url). See https://bugs.ruby-lang.org/issues/15893
