How to get the request's Authentication Header in Tornado

Question

I've been looking on how to get the Authorization Header from a Tornado GET/POST Request, but there's none. Anyone can help on this?

The reason is that I want to implement JWT in my Python application.

For example, this tornado API just creates a GET request:

class HeaderHandler(tornado.web.RequestHandler):
    def get(self):
        headers = tornado.httputil.HTTPHeaders()
        response = {
            'message': str(headers)
        }
        self.write(response)

I want to access this API via http://localhost:{port} and I will add a header which is

Authentication: Bearer {token}

But this code doesn't work. It cannot fetch the authorization header passed to the request. Any help is appreciated. Thanks!

In Tornado, accessing the bearer token from JWT can be achieved by:

token = self.request.headers.get('Authorization')
