Question

In my Rails controller, I have the url that the user inputs:

url_parsed = URI.parse(url)
response = Net::HTTP.get_response(url_parsed)

If the user inputs www.google.com, it gives

undefined method `request_uri' for #<URI::Generic:0x00000002e07908 URL:www.google.com>

on the line response = ....

I want it to display my error page, instead of this error. How can I do it?

Answer 1

Don’t know if your question is why it isn’t working, or how to use the error message in the view.

Why you get the error

EDIT:

I think that it’s because there is no protocol in 'www.google.com', 'http://www.google.com' should work

How to show the error

Rescue the error:

error = nil
begin
  url_parsed = URI.parse(url)
  response = Net::HTTP.get_response(url_parsed)
rescue => error
end
if error
  @error_message = "Your URL wasn't good enough"
  # or you can use error.message if you want
  # then use @error_message in your view
else
  # do stuff when ok
end
