Ruby HTTParty - get the redirected URL

Question

I am trying to send an HTTP request using HTTParty with some parameters,

Eg:

GET URL: http://example1.com?a=123&b=456

response_to_get = HTTParty.get('http://example1.com?a=123&b=456')

The redirect_url for this particular request is http://example2.com

When I tried the URL http://example1.com?a=123&b=456 in browser, it redirects to the expected URL with parameter value appended to it like http://example2.com?c=123trt58, but when I did it using HTTParty, I'm getting an HTML reponse only.

My requirement is to get the URL(http://example2.com?c=123trt58) out from the response.

Thanks in Advance.

If you do not want to follow redirects, but still want to know where the page is redirecting to (useful for web crawlers, for example), you can use response.headers['location']:

response = HTTParty.get('http://httpstat.us/301', follow_redirects: false)

if response.code >= 300 && response.code < 400
    redirect_url = response.headers['location']
end

Slightly corrected @High6 answer:

    res = HTTParty.head("example1.com?a=123&b=456")
    res.request.last_uri.to_s

This will prevent large response download. Just read headers.

To get the final URL after a redirect using HTTParty you can use:

res = HTTParty.get("http://example1.com?a=123&b=456")
res.request.last_uri.to_s

# response should be 'http://example2.com?c=123trt58'

Right choice is res = HTTParty.head("http://example1.com?a=123&b=456") HTTParty.get will download all content even that is 100Mb video file. – Aivils Štoss Jan 23 '17 at 10:04

require 'uri'
require 'net/http'

url = URI("https://<whatever>")

req = Net::HTTP::Get.new(url)
res = Net::HTTP.start(url.host, url.port, :use_ssl => true) {|http|
  http.request(req)
}

res['location']

PS: This is using native ruby HTTP lib.
