Adding authentication to resources

We will configure the Flask-HTTPAuth extension to work with our User model to verify passwords and set the authenticated user associated with a request. We will declare a custom function that this extension will use as a callback to verify a password. We will create a new base class for our resources that will require authentication. Open the api/views.py file and add the following code after the last line that uses the import statement and before the lines that declares the Blueprint instance . The code file for the sample is included in the restful_python_chapter_07_02 folder:

from flask_httpauth import HTTPBasicAuth 
from flask import g 
from models import User, UserSchema 
 
 
auth = HTTPBasicAuth() 
 
 
@auth.verify_password 
def verify_user_password(name, password): 
    user = User.query.filter_by(name=name).first() 
    if not user or not user.verify_password(password): 
        return False 
    g.user = user 
    return True 
 
 
class AuthRequiredResource...
