        password = flask.request.values.get('pass') # input names
        your_register_routine(username, password)
    else:
        # You probably don't have args at this route with GET
        # method, but if you do, you can access them like so:
        yourarg = flask.request.args.get('argname')
        your_register_template_rendering(yourarg)
