If you are finding a way to encode urls in ruby then here is a quick tip -
Short Answer: You could use the URI class or the CGI class.
We have CGI.escape and URI.escape, but they have some slight differences. I have tried to show the differences in IRB as follows -
$ irb irb(main):001:0> str = 'hello world' => "hello world" irb(main):002:0> require 'uri' => true irb(main):003:0> URI.escape(str) => "hello%20world" irb(main):004:0> require 'cgi' => true irb(main):005:0> CGI.escape(str) => "hello+world" irb(main):006:0> url = 'http://example.com/åäö' => "http://example.com/åäö" irb(main):007:0> URI.escape(url) => "http://example.com/%C3%A5%C3%A4%C3%B6" irb(main):008:0> CGI.escape(url) => "http%3A%2F%2Fexample.com%2F%C3%A5%C3%A4%C3%B6"
So i hope you can see the difference now and can choose the one you need.
