same previous program

1- I need a registration page, 2- I need to see the database so when someone register there is a place I can see there information, 3- I need to see the post and get request so when someone try to log in with invalid credentials I can see the requests using postman or curl, 4- Don’t use templates just use FlaskRESTFul, 5- he told us something about authorization and authentication. as before don’t make it a perfect program.
