title: How to authenticate user without auth:api middleware in laravel 5.3?
body: <p>I have a public route that any user can access it. (<code>/timeline</code>).<br>
  In this action if user is authenticated, I must show him if he has liked the post.<br>
  If the route has <code>auth:api</code> middleware I can get authenticated user using <code>$request-&gt;user()</code>, but if I don't use <code>auth:api</code> middleware I can't check if user is authenticated even if user sends correct access_token.<br>
  How can I check if access_token is correct without middleware and authenticate user in controller?</p>
