How can I implement role-based access control in Flask RESTful?

You can use Flask-RESTful along with Flask-JWT-Extended to manage roles. First, define your roles and then create decorators to restrict access.

Can you show me a code example for that?

Sure! Here's a simple example:

from flask import Flask
from flask_restful import Api, Resource
from flask_jwt_extended import JWTManager, jwt_required, get_jwt_identity

app = Flask(__name__)
api = Api(app)
app.config['JWT_SECRET_KEY'] = 'your_secret_key'
jwt = JWTManager(app)

roles = {'admin': ['view', 'edit'], 'user': ['view']}

def role_required(role):
    def wrapper(fn):
        @jwt_required()
        def decorated(*args, **kwargs):
            current_user = get_jwt_identity()
            if current_user['role'] != role:
                return {'msg': 'Access denied'}, 403
            return fn(*args, **kwargs)
        return decorated
    return wrapper

class AdminResource(Resource):
    @role_required('admin')
    def get(self):
        return {'msg': 'Welcome, Admin!'}

api.add_resource(AdminResource, '/admin')

if __name__ == '__main__':
    app.run(debug=True)

What if I want to allow multiple roles to access a resource?

You can modify the role_required decorator to accept a list of roles and check if the current user's role is in that list.
