GET URL that does not exist (404 error)

---

Here we deliberately created a URL that does not exist on the HTTPbin web server. In this case the response was not Net::HTTPOK, so Ruby executed the else part of our program. The code was 404 and the response message was NOT FOUND. I am sure you have already encountered links that returned this error message. BTW you can try to visit the URLs using your regular browser as well to see the same response.

examples/net-http/get_response_get_httpbin_error.rb

require 'net/http'

url = 'https://httpbin.org/qqrq'
uri = URI(url)
# puts(uri)

response = Net::HTTP.get_response(uri)
# puts response.class  # Net::HTTPNotFound
if response.is_a?(Net::HTTPSuccess)
    #puts "Headers:"
    #puts response.to_hash.inspect
    #puts '------'
    puts response.body
else
    puts response.code
    puts response.msg
end

The output was:

404
NOT FOUND
