Creating RESTful Web APIs using Flask and Python by Jimit Dholakia
By leveraging Swagger UI, you’ll create handy documentation for your API along the way. That way, you’ll have the opportunity to test how your API works at each stage of this tutorial and get a useful overview of all your endpoints. The endpoint responsible for accepting new incomes was also refactored. The change on this endpoint was the addition of IncomeSchema to load an instance of Income based on the JSON data sent by the user. As the transactions list deals with instances of Transaction and its subclasses, we just added the new Income in that list. Inside the main module, let’s create a script called index.py.
Before JSON became popular, XML was widely used for open data interchange. JSON involves less overhead when parsing, so you’re more likely to see it when interacting with APIs via Python. You can check out the code from this and other posts on our GitHub repository. In the above example, GET is an flask rest api HTTP verb, home.html is a URI where we want to get the data from, and HTTP/1.1 refers to the HTTP version. Have you ever implemented Google Maps in your application or have seen an app that makes use of Google Maps? Note that in both blueprints, the /hello/ route is calling the hello function.
How to Make Flask API More Secure With Basic Authentication
Once we have updated the value, we will hit send again – and voila! You can check this by sending a GET request again, and your new book should be in the list. HTTP is one of the protocols that allows you to fetch resources. It is the basis of any data transfer on the Web and a client-server protocol. API stands for Application Programming Interface, and it refers to the mode of communication between any two software applications.
This can be achieved using solutions like Nginx or AWS Elastic Load Balancing. By incorporating these testing and debugging practices, you can build a more reliable and maintainable Flask REST API. Regular testing and debugging not only catch immediate issues but also help in maintaining the quality of the API over time. Exploring the creation of REST APIs in Flask, this article guides you through essential steps and best practices. From setting up your environment to securing your API, we cover the crucial aspects needed for efficient API development.
API Endpoints
From the ground up, Flask was built with scalability and simplicity. Flask applications are known for being lightweight, mainly compared to their Django counterparts. Flask developers call it a microframework, where micro (as explained here) means that the goal is to keep the core simple but extensible. Flask won’t make many decisions for us, such as what database to use or what template engine to choose.
Securing Your Flask REST API is crucial to protect your data and services from unauthorized access and vulnerabilities. Implementing security measures is a key step in API development. Error Handling and Response Formatting are critical aspects of a robust Flask REST API. Proper handling ensures that your API responds to errors gracefully, while consistent response formatting makes your API intuitive and user-friendly. However, what good is all of this code if we don’t write tests for it now? Everything that’s not tested will break, so we really should write some tests.
二、RESTful API的优势
You’ll create the corresponding Python code later in this tutorial. The Swagger configuration file is a YAML or JSON file containing your OpenAPI definitions. In this section, you’ll prepare the development environment for your Flask REST API project. First, you’ll create a virtual environment and install all the dependencies that you need for your project. One of the purposes of an API is to decouple the data from the application that uses it, thereby hiding the data implementation details.
Pytest automatically finds this fixture for us, and there is no need to import it. In the world of web development, creating robust RESTful APIs is an essential skill. REST (Representational State Transfer) is a widely used architectural style for designing networked applications. Flask, a micro web framework for Python, provides an excellent platform for building RESTful APIs due to its simplicity and flexibility. In this blog post, we’ll take you through a step-by-step guide on how to build a RESTful API with Flask, covering the fundamentals and best practices.

Web service APIs that are written to follow the REST principles are called RESTful APIs. A. Incoming data can be accessed through the request object in Flask. https://remotemode.net/ To access data in the request body, we can use the request.get_json() method, which parses the request body as JSON and returns a Python dictionary.
Many web services, like YouTube and GitHub, make their data accessible to third-party applications through an application programming interface (API). One of the most popular ways to build APIs is the REST architecture style. Python provides some great tools not only to get data from REST APIs but also to build your own Python REST APIs. The post method obtains request data in JSON format and adds the data to the database. Here we create a ProductView class that defines a get and post function.
