How to Use OAuth2 Authentication in Django REST framework

OAuth2 is an open standard for authorization that provides a way for users to securely access resources without having to share their credentials. It is widely used in web applications and mobile applications to provide secure access to resources. In this tutorial, we will learn how to use OAuth2 authentication in Django REST framework.

Install the Django OAuth Toolkit

The first step is to install the Django OAuth Toolkit. This is a library that provides an easy way to add OAuth2 authentication to your Django project. To install it, run the following command in your terminal:

pip install django-oauth-toolkit

Once the installation is complete, add the following line to your settings.py file:

INSTALLED_APPS = [ ... 'oauth2_provider', ...]

This will enable the OAuth2 authentication in your Django project.

Add the OAuth2 Authentication to Your Django Project

The next step is to add the OAuth2 authentication to your Django project. To do this, add the following line to your urls.py file:

urlpatterns = [ ... path('o/', include('oauth2_provider.urls', namespace='oauth2_provider')), ...]

This will enable the OAuth2 authentication in your Django project.

Configure the OAuth2 Provider

The next step is to configure the OAuth2 provider. To do this, add the following line to your settings.py file:

OAUTH2_PROVIDER = { 'SCOPES': { 'read': 'Read scope', 'write': 'Write scope', }}

This will configure the OAuth2 provider with two scopes: read and write. You can add more scopes as needed.

Create an OAuth2 Application

The next step is to create an OAuth2 application. To do this, run the following command in your terminal:

python manage.py oauth2_provider_app

This will create an OAuth2 application with the default settings. You can customize the settings as needed.

Configure the Django REST Framework

The next step is to configure the Django REST framework. To do this, add the following line to your settings.py file:

REST_FRAMEWORK = {    'DEFAULT_AUTHENTICATION_CLASSES': (        'oauth2_provider.contrib.rest_framework.OAuth2Authentication',    )}

This will enable the OAuth2 authentication in the Django REST framework.

Test the OAuth2 Authentication

The last step is to test the OAuth2 authentication. To do this, run the following command in your terminal:

python manage.py test

This will run the tests for the OAuth2 authentication. If all the tests pass, then the OAuth2 authentication is working correctly.

Conclusion

In this tutorial, we have learned how to use OAuth2 authentication in Django REST framework. We have installed the Django OAuth Toolkit, added the OAuth2 authentication to our Django project, configured the OAuth2 provider, created an OAuth2 application, configured the Django REST framework, and tested the OAuth2 authentication. With this knowledge, you should be able to easily add OAuth2 authentication to your Django projects.
