Question

There are many discussion about URL escaping in Ruby, but unfortunately I didn’t find an appropriate solution.

In general, URI.escape should do the job, but looks like it doesn’t support all characters, for example it doesn’t escape “[“.

URI.parse(URI.escape("1111{3333"))  

works well.

URI.parse(URI.escape("1111[3333"))

raises an exception.

I understand that “[” is not an eligible character in URL according to RFC, but when I enter it into the browser it takes it, and renders the page, so I need exactly the same behavior.

Do know any ready solution for escaping in Ruby?

Answer 1

I typically use

CGI.escape

to escape URI parameters.

require 'cgi'. 

CGI.escape('1111[3333')
=> "1111%5B3333"
