Question

In Rails controller, I’d like to validate a user-inputted URL (say, it’s in a variable url) by making a request to it, and checking that the response is not 50X. How can I do that?

Answer 1

You can send request from a controller using Net::Http module as follows

uri = URI('http://festivalsherpa.com')
response = Net::HTTP.get_response(uri)

response.to_hash["status"] will return you proper response code
