How to implement cookie support in ruby net/http?

Question

I'd like to add cookie support to a ruby class utilizing net/http to browse the web. Cookies have to be stored in a file to survive after the script has ended. Of course I can read the specs and write some kind of a handler, use some cookie.txt format and so on, but it seems to mean reinventing the wheel. Is there a better way to accomplish this task? Maybe some kind of a cooie jar class to take care of cookies?

Answer 1

The accepted answer will not work if your server returns and expects multiple cookies. This could happen, for example, if the server returns a set of FedAuth[n] cookies. If this affects you, you might want to look into using something along the lines of the following instead:

http = Net::HTTP.new('https://example.com', 443) http.use_ssl = true path1 = '/index.html' path2 = '/index2.html'  # make a request to get the server's cookies response = http.get(path) if (response.code == '200')     all_cookies = response.get_fields('set-cookie')     cookies_array = Array.new     all_cookies.each { | cookie |         cookies_array.push(cookie.split('; ')[0])     }     cookies = cookies_array.join('; ')      # now make a request using the cookies     response = http.get(path2, { 'Cookie' => cookies }) end
