Overview

URI module of ruby can be used to get all parts from a URL. This module can be used to parse a URL and extract all parts https://ruby-doc.org/stdlib-2.5.1/libdoc/uri/rdoc/URI.html

Once the given URL is parsed correctly, then it will return the URI object. We can then access the below information from the URI

Scheme

User Info

Hostname

Port

Pathname

Query Params

Fragment

Once we have all the parts we can concatenate them to get the full hostname along with the port.

Program

Below is the program for the same.

require 'uri'


uri = "https://test:abcd123@techbyexample.com:8000/tutorials/intro?type=advance&compact=false#history"
pasrse_uri = URI(uri)

hostname = pasrse_uri.scheme + "://" + pasrse_uri.hostname + ":" + pasrse_uri.port.to_s

puts hostname

Output
