title: Getting JWT token in SignalR hub
body: <p>I have two requirements:</p>
  
  <ol>
  <li>I want my <code>SignalR</code> hubs to require authentication</li>
  <li>When the request comes in, I want it to come with a <code>JWT token</code> so
  that I can get user data.</li>
  </ol>
  
  <p>It's important to note that I'm using <code>SignalR Core</code> which is still in Alpha and looks like there's been some changes in the API.</p>
  
  <p>I've been doing some research on this for the past couple of hours and I'm a bit confused about how to both pass the <code>JWT Token</code> on the client side and receive it on the server side.</p>
