Programming Ruby 3.2 (5th Edition): B1.0 page 185, response not OK for me

Page 185, last example

response = http.get('/book/ruby3/programming-ruby-1-9')

doesn’t work for me, the response.message is Moved Permanently.

I have no knowledge about talking to networks.

I have no output with URI.open('http://pragprog.com') on page 186, nor with https.

So, that’s a very weird example, in that the code sample (which comes from the older version) hardcodes the output for some reason. Anyway, I didn’t fix it on first pass, because I didn’t have a URL for the new version, but I do have it now, and I should see what happens if I let it run for real. (the code also isn’t in line with Standard Ruby (single-quote strings) so I should clean that up as well.

Thanks

Actually, the whole code example is out of date, so the whole thing is being updated to

require "net/http"

uri = URI("https://pragprog.com/titles/ruby5/programming-ruby-3-2-5th-edition/")
Net::HTTP.start(
  "pragprog.com",
  Net::HTTP.https_default_port,
  use_ssl: true
) do |http|
  request = Net::HTTP::Get.new(uri)
  response = http.request(request)
  if response.code == "200"
    puts response.body.scan(/<img class=".*?" src="(.*?)"/m).uniq[0, 3]
  end
end

It looks more complex as I don’t know this topic, but I got the 3 responses.
Thanks

Yeah, I get that, I may go into more detail about the code, but it also might wind up in the yet-to-be-written section. Thanks!
