There are two modules you can use to build URLs in Ruby. The URI::HTTP module
will build URLs with the http protocol. And then to build URLs with the
https protocol, you can reach for the URI::HTTPS module.
We can specify just the host and optionally include a port if that is
needed.
Here is URI::HTTP in action.
> URI::HTTP.build(host: 'example.com', port: 3000)
=> #<URI::HTTP http://example.com:3000>
> URI::HTTP.build(host: 'example.com', port: 3000, protocol: 'https')
=> #<URI::HTTP http://example.com:3000>Note that we can try to override the protocol, but it will be ignored.
Here is the URI::HTTPS module.
> URI::HTTPS.build(host: 'example.com', port: 3000)
=> #<URI::HTTPS https://example.com:3000>If we want the URL as a string, we can call #to_s on it.
> URI::HTTPS.build(host: 'example.com', port: 3000).to_s
=> "https://example.com:3000"We can even include the path, though be sure to include the leading slash.
> URI::HTTP.build(host: 'example.com', port: 3000, path: '/taco/bell')
=> #<URI::HTTP http://example.com:3000/taco/bell>
> URI::HTTP.build(host: 'example.com', port: 3000, path: 'taco/bell')
