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.

Making HTTP requests to the Django API


Now we can launch Django's development server to compose and send HTTP requests to our unsecure web API (we will definitely add security later). Execute the following command:

python manage.py runserver

The following lines show the output after we execute the previous command. The development server is listening at port 8000.

With the previous command, we will start Django development server and we will only be able to access it in our development computer. The previous command starts the development server in the default IP address, that is, 127.0.0.1 (localhost). It is not possible to access this IP address from other computers or devices connected to our LAN. Thus, if we want to make HTTP requests to our API...
