Overview of this book

Python is the language of choice for millions of developers worldwide that builds great web services in RESTful architecture. This second edition of Hands-On RESTful Python Web Services will cover the best tools you can use to build engaging web services. This book shows you how to develop RESTful APIs using the most popular Python frameworks and all the necessary stacks with Python, combined with related libraries and tools. You’ll learn to incorporate all new features of Python 3.7, Flask 1.0.2, Django 2.1, Tornado 5.1, and also a new framework, Pyramid. As you advance through the chapters, you will get to grips with each of these frameworks to build various web services, and be shown use cases and best practices covering when to use a particular framework. You’ll then successfully develop RESTful APIs with all frameworks and understand how each framework processes HTTP requests and routes URLs. You’ll also discover best practices for validation, serialization, and deserialization. In the concluding chapters, you will take advantage of specific features available in certain frameworks such as integrated ORMs, built-in authorization and authentication, and work with asynchronous code. At the end of each framework, you will write tests for RESTful APIs and improve code coverage. By the end of the book, you will have gained a deep understanding of the stacks needed to build RESTful web services.

Creating resource classes to handle users


We just want to be able to create users and use them to authenticate requests. Thus, we will just focus on creating resource classes with just a few methods. We won't create a complete user management system.

We will create the resource classes that represent the user and the collection of users. First, we will create a UserResource class, which we will use to represent a user resource. Open the views.py file within the service folder and add the following lines after the line that creates the Api instance named service and before the declaration of the NotificationResource class. The code file for the sample is included in the restful_python_2_03_02 folder, in the Flask01/service/views.py file:

class UserResource(AuthenticationRequiredResource): 
    def get(self, id): 
        user = User.query.get_or_404(id) 
        result = user_schema.dump(user).data 
        return result 

The UserResource class is a subclass of the previously coded AuthenticationRequiredResource...
