title: Identity Server4 access logged in users access token
body: <p>I am using the Identity server 4 ( with .Net core 2.0 ) and all the clients are working perfectly and can retrieve the access_token. In my MVC client, i am using following command to retrieve the access_token.</p>
  
  <pre><code>var accessToken = await this.HttpContext.GetTokenAsync("access_token");
  </code></pre>
  
  <p>But for a functional requirement , I need to get this access_token inside my Identity server itself. The same code returns null when I'm trying to use it inside my Identity server's code. </p>
  
  <p>It would be great if someone can help me on this. </p>
