title: HTTP::Request::UnsupportedSchemeError -- Rails -- HTTP gem
body: <p>I'm using Rails 4.2, HTTP gem, Grape for API.
  I'm trying to send request to other website and felt <a href="https://github.com/httprb/http" rel="nofollow">HTTP gem</a> is really awesome!
  <br>
  When I try to request a predefined URL, it works fine. But if I want to dynamically request the URL on various parameters. Say for example, I want to take it from ActiveRecord. like <br></p>
  
  <pre><code>url = Users.find_by_id(1).url
  </code></pre>
  
  <p>And I should be able to send a request to that URL.</p>
  
  <p>But I'm unable to do so. 
  It throws an error: </p>
  
  <pre><code>HTTP::Request::UnsupportedSchemeError
  </code></pre>
  
  <p>Working code :</p>
  
  <pre><code> HTTP.get("https://google.com")
  </code></pre>
  
  <p>I want to dynamically change that "<a href="https://google.com" rel="nofollow">https://google.com</a>" to my URL.</p>
  
  <p>Any workaround mates? </p>
