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.

Summary


In this chapter, we improved the RESTful API in many ways. We added user-friendly error messages for when resources aren't unique. We tested how to update single or multiple fields with the PATCH method and we created our own generic pagination class to enable us to paginate result sets.

Then, we started working with authentication and permissions. We added a user model and we updated the underlying PostgreSQL database. We made many changes in the different pieces of code to achieve a specific security goal and we took advantage of Flask-HTTPAuth and passlib to use HTTP authentication in our API.

Now that we have built an improved a complex API that uses pagination and authentication, we will use additional abstractions included in the framework and we will code, execute and improve unit tests to get ready to encapsulate our API in a microservice, which are the topics of the next chapter.
