title: How to handle refresh tokens in golang/oauth2 client lib
body: <p>There are few examples of using <a href="https://github.com/golang/oauth2" rel="noreferrer">https://github.com/golang/oauth2</a> but none of them covers usage of refresh tokens. I've tried few approaches, but i'm still unsatisfied with my results.</p>
  
  <p>Is there any example code, or maybe you know some project at <strong>Github</strong> using <code>oauth2 lib</code> to take as example?</p>
