title: How to get the bearer token in the Asp .Net Core SignalR Hub?
body: <p>I need access to the bearer token raw string (the token itself) in the Asp.Net Core SignalR Hub.</p>
  <p>I need it because i have to use it when I'm making HttpClient Call to other microservice that requires the token from my hub.</p>
  <p>I tried to create Per-request service that has Token property, but SignalR does not use Per-Request pattern. The token is sent only when client is connecting, and not always.</p>
  <p>Anyway I need to get access to the bearer token and don't know how.
  Please help.</p>
