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.

Executing HTTP requests to test throttling policies


Launch Django's development server to compose and send HTTP requests. Execute either of the following two commands based on your needs:

python manage.py runserverpython manage.py runserver 0.0.0.0:8000

 

 

Now, we will write commands to compose and send HTTP requests many times. In order to do so, we will learn how to achieve this goal with any of the following options combined with http and curl commands. Select the most appropriate one based on your needs. Don't forget that you will need to have the virtual environment activated in any of the options you select to run the commands when you use the http command:

  • macOS: Terminal with a Bash shell.
  • Linux: Terminal with a Bash shell.
  • Windows: Cygwin Terminal or Linux Bash Shell (also known as the Windows Subsystem for Linux). The steps are the same for a Terminal with a Bash shell.
  • Windows: Windows PowerShell.

We will run the following command six times to compose and send an HTTP GET request to retrieve...
