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.

4: Authenticated Services and Security with JWTs

Activity 7: Implementing Access Control on the publish/unpublish Recipe Function


  1. Modify the put method in RecipePublishResource to restrict access to only authenticated users. In resources/, add the @jwt_required decorator on top of the RecipePublishResource.put method. Use the get_jwt_identity() function to identify whether the authenticated user is the owner of the recipe:
        def put(self, recipe_id):
            recipe = Recipe.get_by_id(recipe_id=recipe_id)
            if recipe is None:
                return {'message': 'Recipe not found'}, HTTPStatus.NOT_FOUND
            current_user = get_jwt_identity()
            if current_user...
