Use authorization decorator for UI Based session login as well as Auth Header Request like in Basic Auth

flask_login_api.py

def validate_api_or_user(f):
	@wraps(f)
	def decorated(*args, **kwargs):
		auth = request.authorization
		print auth
		if not auth:  # no header set
			if current_user.is_authenticated:  # check active session
				g.user = current_user
				return f(*args, **kwargs)
			else:
				abort(401)
		user = User.objects.get(username=auth.username)
		if user is None or not user.verify(auth.password):
			abort(401)
		g.user = user
		return f(*args, **kwargs)
	return decorated
