API Authentication with Django Knox and Postman Testing:
Django-Knox is a framework that makes the authentication of the API endpoints built with the Django Rest Framework easier. However, Knox is also a token-based authentication like JSON Web Token (JWT) auth. Django-Knox comes with well-detailed documentation for easy implementation.
Key takeaways
In this tutorial, the following are the subjects to be covered:
Why Knox is used with Django Rest Framework.
Designing Rest API endpoints with class-based views.
Securing endpoints with Django-Knox.
Testing API with postman application.
Now that you have a grasp of what Django-Knox is, let us discuss it in detail.
Why Django-Knox with DRF
Like I said earlier, Knox solves some problems found with the built-in TokenAuthentication in DjangoRestFramework. How?
Token is generated per one call in login views with Knox. This allows each user to have one active token that gets deleted when a user logs out.
Knox provides an encrypted form of tokens before storing them in the database. This feature would not allow any hacker to have access even if the database is compromised.
Expiration of tokens is also a key feature of Knox that is not inbuilt in DRF.
If you are curious to know more about all these benefits, head on to Django-Knox.
Designing Rest API with class-based views
We are building the Rest API endpoints for an application called Leads. Leads will contain all information of leads, like name, email, message, and owner models.
To build the API endpoints, we have to initialize the Django project. I believe you are familiar with the Django Rest Framework project setup. But if you are not, follow the below commands.
