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.

Configuring Endpoints

Now that we have defined all our resources, we will set up some endpoints so that users can send requests to them. These endpoints can be accessed by the users and are connected to specific resources. We will be using the add_resource method on the API object to specify the URL for these endpoints and route the client HTTP request to our resources.

For example, the api.add_resource(RecipeListResource, '/recipes') syntax is used to link the route (relative URL path) to RecipeListResource so that HTTP requests will be directed to this resource. Depending on the HTTP verb (for example, GET, and POST), the request will be handled by the corresponding methods in the resource accordingly.

Exercise 10: Creating the Main Application File

In this exercise, we will create our file, which will be our main application file. We will set up Flask and initialize our flask_restful.API there. Finally, we will set up the endpoints so that users can send...
