Python API Development Fundamentals

By: Jack Chan, Ray Chung, Jack Huang

Overview of this book

Python is a flexible language that can be used for much more than just script development. By knowing the Python RESTful APIs work, you can build a powerful backend for web applications and mobile applications using Python. You'll take your first steps by building a simple API and learning how the frontend web interface can communicate with the backend. You'll also learn how to serialize and deserialize objects using the marshmallow library. Then, you'll learn how to authenticate and authorize users using Flask-JWT. You'll also learn how to enhance your APIs by adding useful features, such as email, image upload, searching, and pagination. You'll wrap up the whole book by deploying your APIs to the cloud. By the end of this book, you'll have the confidence and skill to leverage the power of RESTful APIs and Python to build efficient web applications.

In this chapter, we have learned a lot of things. The data verification of an API through marshmallow is very important. This function should also be constantly updated in the production environment to ensure that the information we receive is correct.

In this chapter, we started with the verification of registered members and then talked about basic verification methods, such as setting mandatory fields, performing data type validation, and so on. Apart from data validation, marshmallow can be used for data filtering as well. We can use the exclude parameter to display the user email field. Based on what we learned, we then developed customized verifications for our application, such as verifying the length of the recipe creation time.

At the end of this chapter, we added the functionality to get all the recipes written by our favorite author. Then, we searched for different publish statuses through the visibility parameter and applied access control accordingly.
