Ruby - Getting page content even if it doesn't exist

I am trying to put together a series of custom 404 pages. 

require 'uri'

def open(url)
 page_content = Net::HTTP.get(URI.parse(url))
 puts page_content.content
end

open('http://somesite.com/1ygjah1761')

the following code exits the program with an error. How can I get the page content from a website, regardless of it being 404 or not.

Solution

  • You need to rescue from the error

     def open(url)
   require 'net/http'
   page_content = ""
   begin
     page_content = Net::HTTP.get(URI.parse(url))        
     puts page_content
   rescue Net::HTTPNotFound         
     puts "THIS IS 404" + page_content
   end
 end
