title: Not receiving Google OAuth refresh token
body: <p>I want to get the access token from Google.  <a href="https://developers.google.com/youtube/2.0/developers_guide_protocol_oauth2#OAuth2_Server_Side_Web_Applications_Flow" rel="noreferrer">The Google API says</a> that to get the access token, send the code and other parameters to token generating page, and the response will be a JSON Object like :</p>
  
  <pre><code>{
  "access_token" : "ya29.AHES6ZTtm7SuokEB-RGtbBty9IIlNiP9-eNMMQKtXdMP3sfjL1Fc",
  "token_type" : "Bearer",
  "expires_in" : 3600,
  "refresh_token" : "1/HKSmLFXzqP0leUihZp2xUt3-5wkU7Gmu2Os_eBnzw74"
  }
  </code></pre>
  
  <p>However, I'm not receiving the refresh token.  The response in my case is:</p>
  
  <pre><code>{
   "access_token" : "ya29.sddsdsdsdsds_h9v_nF0IR7XcwDK8XFB2EbvtxmgvB-4oZ8oU",
  "token_type" : "Bearer",
  "expires_in" : 3600
  }
  </code></pre>
