CORS in Flask

Dealing with cross origin requests is common in APIs. In this video I show you how to handle CORS errors in case you get them.

Download a Flask template ready to plug in your business logic

Let’s assume after lots of hard work you have your machine learning model running the way it should. This model could be one which responds to a user’s request to classify a tweet sentiment or identify objects in an image or recommend a product or some other algorithm unique to your needs. You would now like to quickly deploy this model. The article below is an explanation of the template that I have created to get you up and running quickly.

Web development with python and flask: part 3

In this part of the series, we will be taking a look at the HTTP protocol, request/response objects, their application in flask, properties, and their related methods. We will take steps to import it from the flask module, use its properties, and look at some of its related usages

Web applications implement one of the internet data and message exchange architectures that is based on HTTP protocol. The HTTP protocol is just one of the many application layers of TCP/IP. The TCP/IP(Transmission Control Protocol/Internet Protocol) is used as a standard for transmitting data over networks. In simple terms, HTTP has rules, properties, and methods that implement the transmission of messages in form of hyperlinks over the communication structures enforced by the TCP/IP.

.You must know that the internet is based on connected physical computational devices over either copper wires, fiber optical cables, wireless, and other media to form data transmission and retrieval systems across the globe. Trust me, that is a whole career field in itself and we are not interested in its elaborate ramblings in this post.

Building REST APIs using Flask-RESTPlus, SQLAlchemy & Marshmallow

Python is an interpreted, high-level, and general-purpose programming language. It can be used to develop business applications as well as system scripts, has data science related capabilities, desktop GUIs, and also offers many choices for web and internet development.
Flask is a micro web framework written in Python that helps you build web applications easily. It does not require tools or libraries and has no database abstraction layer, form validation, serializers, user management, or built-in internationalization. However, it supports extensions that can add application features as if they were implemented in Flask itself. An aspiring Flask developer must then choose the right extensions and combine them together to get the right set of functions, as applicable.
The aim of this tutorial is working with Flask extensions that help us create a production environment ready Python application and to integrate with Swagger UI without a hitch. We will learn to build a Rest API using Flask extensions such as Flask-RestPlus, Flask-Marshmallow, and Flask-SQLAlchemy and share the API using Swagger UI.
Flask and Flask-RestPlus
Flask is a lightweight web server and framework. Although, we can create a Web API directly with flask, the Flask-RESTPlus extension makes it simpler to build Rest APIs.
It supports namespaces, which are ways of creating prefixes and structuring the code.
It has a full solution for parsing and validating the input parameters. This means that we have an easy way of dealing with endpoints that require several parameters and validate them.
Its best feature is the ability to automatically generate interactive documentation for our API using Swagger UI.
Marshmallow is an ORM/ODM/framework-agnostic library developed to simplify the process of serialization and deserialization. The Flask-Marshmallow extension acts as a thin integration layer for Flask and Marshmallow that adds additional features to Marshmallow, including URL and hyperlink fields for HATEOAS-ready APIs. It also integrates with Flask-SQLAlchemy and reduces some boilerplate code.

An API, which stands for Application Programming Interface, is just what its name suggests it is. It’s an Interface for other application programs. Meaning it helps connect different programs and machines to access and share data. An interface is just a medium facilitating the access of certain functionality or an intermediary between two systems. In the post about REST here, we gave an example of connecting to a Facebook graph API to access Facebook user information to log in a user to a third-party application.

REST ,an acronym for Representational State Transfer, is just a style guide for creating these APIs.We have a complete and indepth post here discussing what REST is, read it to have a clear understanding about that topic(REST) before continuing.

In this tutorial we will be looking at how we can create our own REST API in Python using flask micro-framework.
