Extract data from URL

I would like to get some data from a URL in Ruby. I have a URL matching:

"http://localhost:3000/cars/test/1/direction/2"

I would like to extract the value after /test (here it is 1). I know how to extract the other values.

I created a URI object:

uri = URI.parse("http://localhost:3000/cars/test/1/direction/2")
uri.port = 3000
uri.path = /cars/test/1/direction/2
uri.host = localhost

But, I don't know how to extract the internal parameters.

Do I have to parse this URL or is there an existing solution?

The quick and easy solution is to just use split.

uri = URI.parse("http://localhost:3000/cars/test/1/direction/2")
url_path = uri.path
url_parts = url_path.split("/")
url_parts[3] # => "1"

I think this might work well for you as it identifies the leading name as well:

url_parts = uri.path.scan(/\/(\w+)\/(\d+)/)
#=> [["test","1"],["direction","2"]]

Then you could even make it a Hash using:

Hash[url_parts]
#=> {"test" => "1", "direction" => "2"}
